Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The existing message middleware access method uses a consumption node (also called a client) of a complex interaction Protocol based on a Transmission Control Protocol (TCP) to access the message middleware, wherein the consumption node is a Transport layer (Transport layer) communication Protocol which is oriented to connection guidance, reliable and based on byte streams, and the step of subscribing the message by the consumption node comprises the following steps:
1. message middleware (for example, MQServer1 and MQServer2) registers its own information with a Registry (the Registry is called Registry, which contains subscription subject and service information, for example, the Registry maintains routing information on MQServer1 in record T1, and T2 on MQServer 2);
2. the consumer node subscribes to T1, and queries Registry to obtain routing information of T1;
3. the consumer node determines that the message of the T1 subscription subject is maintained in MQServer1 according to the routing information, and the consumer node establishes a long link with MQServer 1;
4. the consumer node initiates a continuous long polling mode consumption request to the MQServer1 by using the established long link, and the message is continuously consumed locally, wherein the consumption rhythm depends on whether a new message is delivered on the T1.
The current TCP-based message middleware consumption mode is characterized in that an interaction protocol between a consumer node and the message middleware is complex, message subscription logic in the consumer node is heavy, logic blocks of the consumer node need to execute operations including but not limited to instance heartbeat state maintenance, load balance between sending and consumption, ACL (access control list) authentication, flow control, an ACK (acknowledge character) mechanism and Trace tracking, and any one logic block is greatly changed and needs to push the consumer node of a user to update codes.
Aiming at the problems of the message middleware consumption mode based on the TCP, the invention provides the middleware consumption agent method embodiment; in the embodiment of the invention, the method is based on an HTTP (HTTP, Hypertext transfer protocol HyperFile transfer protocol) protocol, and the method comprises the following steps: when detecting that the proxy server is started, accessing a configuration center corresponding to the proxy server to acquire configuration information; determining a consumption group according to the configuration information, and starting an agent cluster according to the consumption group; obtaining subscription information in the message middleware through the agent cluster, and storing the subscription information to a buffer pool; and sending the subscription information in the buffer pool to each consumption node corresponding to the consumption group according to the configuration information.
The message middleware consumption proxy method based on the HTTP in the embodiment of the invention is used, effectively solves the problems existing in the message middleware consumption mode based on the TCP, and has the following advantages that:
1. by keeping the heartbeat state, balancing the load of sending and consuming, ACL authentication, flow control, an ACK mechanism, Trace tracking and the like in the logic block of the proxy server, the maintenance by the consuming node is not needed, namely the self-maintenance can be realized, the upgrading of the consuming node is not needed to be frequently promoted, and the operation and maintenance difficulty is reduced. The logic blocks of the consumption nodes are migrated to the proxy server, so that the proxy server can only reserve the sending and consumption carried by the HTTP protocol, consume the ACK instruction, and develop a proxy node of a certain language only by realizing a plurality of simple HTTP instructions, thereby greatly reducing the workload of language diversification.
2. The consumer nodes are connected with the proxy server, the proxy server controls the proxy nodes in the proxy cluster to access the message middleware, the number of the proxy nodes is limited, the long connection number of TCP (transmission control protocol) on the message middleware is greatly converged, the reliability of a message middleware server is enhanced, and the potential safety hazard that the message middleware server is directly exposed to the consumer nodes can be eliminated through safety verification.

For convenience of understanding, the embodiment is described by taking an example in which the proxy server is disposed at the front end of the message middleware.
Before the steps of the first embodiment of the message middleware consumption agent method of the present invention, a consumption agent framework is created in advance, and a message push operation is performed through the consumption agent framework, referring to fig. 2, fig. 2 is a schematic flow diagram of the consumption agent configuration in the first embodiment of the message middleware consumption agent method of the present invention, and the steps of the consumption agent configuration in the present embodiment include:
step S01, a configuration center corresponding to the proxy server is created;
the agent server creates a consumption agent frame according to the public code information of the consumption agent written by a developer in advance, the consumption agent frame refers to the public code for executing the consumption agent, the developer writes function codes in the consumption agent frame, the agent server synchronously sets a configuration center, wherein the configuration center is a data table or a data base for storing configuration information, the configuration information refers to the information of the subscription theme, the subscription time, the consumption node identification and the like of each consumption node configured by a user or the developer, the agent server calls an agent cluster (the agent cluster replaces the consumption node to acquire the subscription information from the message middleware) by using the consumption agent frame according to the configuration information in the configuration center, each agent node in the agent cluster can replace one consumption node or a plurality of consumption nodes to acquire the subscription information subscribed by each consumption node from the message middleware, then, storing the subscription message to a cache, and pushing the subscription message in the cache to each consumption node), executing consumption proxy operation through the proxy cluster, specifically:
step S02, when receiving the agent configuration request, outputting an information configuration page;
the user triggers the agent configuration request at the agent server, wherein the triggering mode of the agent configuration request is not specifically limited, and when the agent server receives the agent configuration request, the agent server outputs an information configuration page so that the user can input configuration information such as subscription subjects, subscription time, consumption node identifiers and the like of each consumption node at the information configuration page.
And step S03, acquiring the configuration information input based on the information configuration page, and storing the configuration information to a configuration center.
The method comprises the steps that a proxy server obtains configuration information input based on an information configuration page, wherein the configuration information comprises proxy configuration information and consumption configuration information with a mapping relation (the mapping relation can be one-to-one mapping, also can be one-to-many mapping, and preferably is one-to-many mapping, so that a message middleware can be prevented from being connected with a large number of long chains), the proxy configuration information refers to proxy cluster information with communication connection with the proxy server, the consumption configuration information refers to subscription subjects, subscription time, consumption node identifications and the like of each consumption node, and the proxy server stores the proxy configuration information and the consumption configuration information to a configuration center according to different dimensions.
It is understood that the configuration information in this embodiment may be updated in real time, that is, the time for triggering the agent configuration request in this embodiment is not limited, for example, the agent configuration request may be triggered during the process of executing the consuming agent; proxy configuration requests may be triggered when a consuming node updates; the triggering manner of the agent configuration request is not specifically limited, and the agent configuration request may be automatically triggered by the agent server, for example, when it is detected that a new consumption node accesses the message middleware, the agent server automatically triggers the agent configuration request to acquire the configuration information of the consumption node, and stores the configuration information in association with the consumption node; or the agent configuration request can be triggered manually and actively, for example, the agent configuration request is triggered by clicking a virtual key of 'configuration' on a display interface of the agent server by a user.
In the embodiment, the consumption agent operation of the message middleware is executed by the agent server, so that the consumption node does not need to be directly butted with a data interface provided by the message middleware, when the message middleware is upgraded, the agent server can carry out the consumption agent operation according to the latest configuration information only by updating the configuration information in the configuration center, the upgrading of each consumption node is not needed, the maintenance of the consumption nodes is more convenient, the long chain accessed by the message middleware comes from the agent node controlled by the agent server, one agent node can act on a plurality of consumption nodes, the number of the long chain accesses in the message middleware is less, the phenomenon of overload of the data accessed in the message middleware can not occur, the stability and the reliability of the message middleware are improved, and meanwhile, the agent nodes controlled by the agent server are verified in advance, thus, the security of the message middleware is better ensured.
Referring to fig. 3, fig. 3 is a flowchart illustrating a first embodiment of a message middleware consumption agent method according to the present invention, where the method includes:
step S10, when detecting that the proxy server is started, accessing a configuration center corresponding to the proxy server to obtain configuration information.
The proxy server is provided with a monitor, when the proxy server is started, the proxy server accesses a preset configuration center to acquire configuration information in the configuration center, so that the proxy server starts each proxy node in the proxy cluster to execute consumption proxy operation according to the configuration information, namely, the proxy server judges whether the configuration information comprises proxy configuration information and consumption configuration information with mapping relation; if the configuration information includes agent configuration information and consumption configuration information having a mapping relationship, the agent server starts each agent node in the agent cluster according to the mapping relationship in the configuration information, in this embodiment, each agent node in the agent cluster is started according to the mapping relationship, and the agent server can establish the mapping relationship according to information such as a network address, so that the message agent is more convenient; if the configuration information does not include agent configuration information and consumption configuration information with a mapping relationship, the agent server randomly starts each agent node in the agent cluster, in this embodiment, each agent node in the agent cluster is randomly started, so that each agent node is a mutual thermal device, when one agent node fails, the agent node can be replaced by other agent nodes, and the problem of agent abnormality is avoided; it is understood that the proxy servers and the proxy nodes in the proxy cluster are distributed architectures, and the proxy nodes in the proxy cluster having the access configuration center can be used as the proxy servers.
And step S20, determining a consumption group according to the configuration information, and starting an agent cluster according to the consumption group.
The proxy server determines a consumption group according to the configuration information, that is, the configuration center contains pre-configured configuration information, the proxy server divides the consumption nodes corresponding to the consumption node identifications in the configuration information into groups according to the subscription theme, subscription time and/or consumption node identifications of the consumption nodes in the configuration information to form a plurality of consumption groups, for example, the proxy server takes the consumption nodes corresponding to the consumption node identifications with the same subscription theme as a consumption group; or, the agent server takes the consumption nodes corresponding to the consumption node identifications with the same subscription time as a consumption group; or the proxy server determines the network address information of each consumption node according to the consumption node identifier, and the like, and the proxy server divides the consumption nodes corresponding to each consumption node identifier into consumption groups according to the network address information; the agent server associates each consumption group with the agent node, and the agent server takes the associated agent node as an agent cluster and then controls to start the agent cluster.
Step S20 in this embodiment specifically includes:
a1, acquiring the consumption node identification in the configuration information and the subscription theme corresponding to the consumption node identification, and forming a consumption group by the consumption node identifications with the same subscription theme;
step a2, associating each consumption group with a preset proxy node individually, forming the associated preset proxy nodes into a proxy cluster, and starting the proxy cluster.
The proxy server obtains consumption node identifiers in the configuration information and subscription themes corresponding to the consumption node identifiers, and the proxy server forms consumption group by using the consumption node identifiers with the same subscription theme, that is, in this embodiment, the proxy server forms a consumption group by using the consumption nodes with the same subscription theme in the configuration information, associates each consumption group with a preset proxy node (the preset proxy node is a client of a preset specific message subscription logic), forms a proxy cluster by using the associated preset proxy nodes, and starts the proxy cluster to execute message subscription operation.
It can be understood that, in the embodiment, the determining of the consumption groups is performed by dividing the consumption groups by taking the subscription topic as an example, and in the actual application process, the proxy server may also divide the consumption groups according to other dimensions, so that the message subscription is more flexible.
For example, in the embodiment, the proxy server is communicatively connected to the proxy cluster, and the proxy node in the proxy cluster acquires subscription information from the message middleware instead of the consuming node, and feeds back the subscription information to the consuming node, in order to prevent the message middleware from accessing a large number of nodes, each agent node in the agent cluster in this embodiment may correspond to a consumption group (the number of consumption nodes included in one consumption group is not limited, and preferably, the consumption node group in this embodiment includes a plurality of consumption nodes), for example, there are actually one hundred consumption nodes, however, the one hundred consuming nodes have certain homogeneity, for example, 20 consuming nodes N0-N19 are all nodes of the service system S1, 30 consuming nodes N20-N49 are nodes of the service system S2, the other 50 consuming nodes N50-N99 are nodes of the service system S3; the proxy server only needs to construct three homogeneous consumption groups respectively aiming at S1, S2 and S3, each consumption group is associated with one proxy node, namely, the message distribution of 100 nodes can be completed through 3 proxy nodes.
However, the problem of intra-group data distribution needs to be solved, because the proxy node and the consumption node are in a one-to-many relationship on the proxy server, for example, a message reaches S2, and needs to be distributed to N20-N49 according to a certain rule, which is more suitable for a scenario with a large number of consumption nodes, in this embodiment, steps S30 to S40 specifically describe the steps of consumption distribution.
Step S30, obtaining the subscription information in the message middleware through the proxy cluster, and storing the subscription information in a buffer pool.
The proxy server obtains the subscription information in the message middleware through the proxy cluster, that is, the proxy server obtains the subscription information of each consumption group through each proxy node in the proxy cluster, at this time, because one proxy node corresponds to one consumption group, and one consumption group comprises one or more consumption nodes, at this time, the proxy node cannot directly perform message distribution operation, and therefore, the proxy server stores the obtained subscription information to a buffer pool of the proxy server.
Step S40, sending the subscription information in the buffer pool to each consumption node corresponding to the consumption group according to the configuration information.
The proxy server sends the subscription information in the buffer pool to each consumption node corresponding to the consumption group according to the configuration information, namely, the proxy server determines a consumption node identifier corresponding to the subscription information in the buffer pool, and the proxy server distributes the subscription information to the consumption nodes according to the consumption node identifier.
It should be noted that, in the first embodiment of the message middleware consumption proxy method of the present invention, the proxy server uses a Push model, and the proxy server needs to maintain subscription information, so that the proxy server is simple enough and does not introduce a risk of a tamper with insufficient resources.
In the embodiment of the invention, the proxy server is preset, the access configuration center acquires the configuration information when the proxy server is started, the proxy server starts the proxy cluster according to the configuration information and accesses the message middleware through the proxy cluster, so that when the protocol of the message middleware is changed, the proxy server can start the corresponding proxy cluster according to the new configuration information to acquire the subscription information in the message middleware without upgrading operation aiming at each consumption node, the operation and maintenance cost of the consumption nodes is reduced, meanwhile, each proxy node in the proxy cluster can proxy a plurality of consumption nodes according to the configuration information, the connection of the access consumption nodes is less, the stability of the message middleware is improved, and the performance occupation of the message middleware is reduced; in addition, because the agent nodes in the agent cluster are pre-authenticated, the message middleware cannot be prevented from being attacked, and the safety of the message middleware is improved.
After step S40 of the first embodiment, in order to avoid that the consuming node does not receive the subscription message, the determining step is set in this embodiment, and specifically includes:
and if the confirmation character information fed back by the consumption node is not received within a preset time period, the step of sending the subscription information in the buffer pool to each consumption node corresponding to the consumption group according to the configuration information is executed until the confirmation character information fed back by the consumption node is received.
When the proxy server does not receive the confirmation character information fed back by the consumption node within a preset time period (the preset time period can be flexibly set according to specific scenes), the proxy server executes the step of sending the subscription information in the buffer pool to each consumption node corresponding to the consumption group according to the configuration information until the confirmation character information fed back by the consumption node is received.
That is, when the proxy server pushes a message to the consuming node, problems such as network flash, host power down, failure, or program failure occur when the service side processes the message, which may result in a situation that the delivery of the in-transit message fails, and the proxy server considers that the delivery has been successful, but the message does not actually reach the consuming node. An ACK mechanism is introduced, when a consumption node receives a message, ACK confirmation information is responded to a proxy server, for the proxy server, the message which is delivered but does not receive the ACK confirmation information is retried, and the message is pushed for N times to a homogeneous instance in the consumption group, wherein a mode of blocking synchronous ACK or a mode of non-blocking asynchronous ACK is adopted, and in order to improve the Push performance of the proxy server, the mode of non-blocking asynchronous ACK is adopted.

In this embodiment, when the number of consumption nodes in the consumption group is one, the message is directly sent without adding the cache pool, so that the operations of the consumption nodes are reduced, and the message transmission efficiency is improved.
