Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
As used herein, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
A message agent method flow of the embodiment of the present application based on a multi-protocol access block chain network is shown in fig. 1, and the embodiment includes the following steps:
step s101, creating an access request ID, and associating a message access protocol interface with the access request ID;
specifically, different identification numbers can be set for different message access protocols, such as JMS, AMQP, redis, and store, and since the message access protocols all operate after receiving an access request from a client, an access request ID can be set for a message access protocol interface, the access request ID is carried in the access request from the client, and which message access protocol interface is called by the access request ID of the current client access request is identified.
Step s102, receiving an access request carrying the access request ID of a client, acquiring a message access protocol interface according to the access request ID, and generating an access message through the message access protocol interface;
specifically, after receiving an access request from a client, because the access request carries an access request ID, a message access protocol interface corresponding to the access request ID can be queried through the access request ID, and after determining a called message access protocol interface, an access message can be generated according to the received access request from the client.
And step s103, converting the access message and then sending the converted access message to a block chain network.
Specifically, since different message access protocols apply different message formats, and the blockchain network cannot identify the message format of each message access protocol, the access message needs to be converted before being sent to the blockchain network.
Specifically, the conversion needs to be performed according to a predefined message format, otherwise, the conversion cannot be identified between multiple message access protocols and the blockchain network, for example, the conversion is uniformly performed between the message access protocols and the blockchain network into the JSON format in a preset manner, and the JSON format conforms to the RESTFul architecture standard.
Specifically, the message conversion may be performed by a message middleware, and the connection between the blockchain network and the client is performed by setting the message middleware, where the message middleware includes a message protocol plug-in on the uppermost layer and a message queue on the lowermost layer. The message protocol plug-in supports multiple development languages and different message access protocols, such as the above-mentioned JMS, AMQP, redis, and store protocols, and different message protocol plug-ins are developed corresponding to each protocol. Meanwhile, the message protocol plug-in supports the hot plug technology, and realizes the hot plug effect of the plug-in by integrating IronPython or integrating other script engines in the message protocol plug-in, so that when a new message protocol plug-in is integrated in the message middleware after being developed, the Reset operation of the message middleware is not needed, or the system calling the message middleware is not needed to be restarted.
Specifically, after receiving an access request from a client, a message protocol plug-in is selected according to an access request ID in the access request, and after determining the message protocol plug-in, the access request may generate an access message according to the determined message protocol plug-in, and then the access message is converted according to a predetermined message format and sent to a block chain network, or the access request may be stored in a message queue first, and the storage sequence may be performed according to a time sequence of generation of the access message, and then the access message is sent according to the stored sequence.
In this embodiment, by constructing a middleware between the blockchain network and the client and converting the message between different protocols and the blockchain network through the middleware, access to the blockchain network by different development application languages is effectively supported, and the universality and flexibility of different protocol interfaces are improved.
Fig. 2 is a schematic flowchart of a message brokering method based on a multi-protocol access block chain network according to an embodiment of the present application, where as shown in the step s102, after receiving an access request carrying an access request ID from a client, acquiring a message access protocol interface according to the access request ID, and generating an access message through the message access protocol interface, the method includes:
step s201, creating a message sending queue, and storing the access message in the message sending queue according to the generated time sequence;
specifically, after the access message is generated, a sending message queue may be created, the access messages generated by different message access protocols may be stored in the sending message queue, and the access messages may be stored in the sending message queue according to the generated time sequence.
And step s202, sending the access messages in the sending message queue in sequence.
Specifically, after the access messages are stored, the access messages in the transmission message queue are arranged according to the generated time sequence, and are transmitted one by one, and the transmission sequence is according to the sequence of the access messages stored in the transmission message queue, that is, the earliest stored access message is transmitted first.
In this embodiment, by storing and sequentially sending the access messages, system crash caused by concurrent messages can be avoided.
Fig. 3 is a schematic flowchart of a message brokering method based on a multi-protocol access block chain network according to an embodiment of the present application, where as shown in the step s202, after sending access messages in the send message queue in sequence, the method includes:
step s301, setting a time limit for the sent access message;
specifically, after the access message is sent, a time limit may be set for the sent access message, the time limit may be completed by a timer, for example, after the access message is sent, a timer may be started, and the time of the timer may be preset, for example, set to 1s.
Step s302, after the time limit is over, if no feedback message is received, resending the access message.
Specifically, the time limit is overtime can be determined by a timer, for example, the timer is set to 1s, the timer is started after the access message is sent, after the time exceeds 1s, the feedback message of the blockchain network is still not received, the time limit is determined to be overtime, and then the access message can be resent.
In this embodiment, the access message is retransmitted by setting a time limit, so that the message is not lost.
Fig. 4 is a schematic flowchart of a message brokering method based on a multi-protocol access block chain network according to an embodiment of the present application, where as shown in the drawing, in step s103, the converting the access message and sending the converted access message to the block chain network includes:
step s401, presetting a message format matched with a block chain network;
specifically, since different message access protocols apply different message formats, and the blockchain network cannot identify the message format of each message access protocol, the access message needs to be converted before being sent to the blockchain network.
Specifically, the conversion needs to be performed according to a predefined message format, otherwise, the conversion cannot be identified between multiple message access protocols and the block chain network, for example, the conversion is uniformly performed between the message access protocols and the block chain network into the JSON format in advance, and the JSON format is met.
Step s402, converting the access message according to the message format, binding the converted access message with the access request ID, and then sending the bound access message to a block chain network.
Specifically, the message conversion may be performed by a message middleware, and the connection between the blockchain network and the client is performed by setting the message middleware, where the message middleware includes a message protocol plug-in on the uppermost layer and a message queue on the lowermost layer. The message protocol plug-in supports multiple development languages and different message access protocols, such as the above-mentioned JMS, AMQP, redis, and store protocols, and different message protocol plug-ins are developed corresponding to each protocol. Meanwhile, the message protocol plug-in supports the hot plug technology, and realizes the hot plug effect of the plug-in by integrating IronPython or integrating other script engines in the message protocol plug-in, so that when a new message protocol plug-in is integrated in the message middleware after being developed, the Reset operation of the message middleware is not needed, or the system calling the message middleware is not needed to be restarted.
Specifically, after receiving an access request from a client, selecting a message protocol plug-in according to an access request ID in the access request, after determining the message protocol plug-in, generating an access message according to the determined message protocol plug-in for the access request, then converting the access message according to a predetermined message format, and sending the access message to a block chain network, or storing the access request in a message queue, where the storage sequence may be according to a time sequence of access message generation, and then sending the access message according to the stored sequence.
Specifically, after the access message is converted according to a predetermined message format, the converted access message may be bound with an access request ID, and then the access request ID is sent to the blockchain network, so that after the blockchain network receives the access message, the feedback message corresponding to the access message may also carry the access request ID when the blockchain network sends the feedback message.
In this embodiment, by setting a predetermined message format and converting the access message according to the predetermined message format, the message access protocol and the blockchain network can be effectively communicated with each other.
Fig. 5 is a schematic flowchart of a message brokering method based on a multi-protocol access block chain network according to an embodiment of the present application, where as shown in the figure, step s103, after converting the access message and sending the access message to the block chain network, includes:
step s501, when receiving a feedback message of a block chain network, acquiring an access request ID according to the feedback message;
specifically, since the access message is bound to the access request ID, the feedback message sent by the blockchain network also needs to carry the access request ID, and when the feedback message of the blockchain network is received, the access request ID can be obtained in the feedback message.
Step s502, converting the feedback message according to the message format;
specifically, after receiving a feedback message of the blockchain network, the feedback message may be converted according to a preset message format, where the converted feedback message is a message format adapted to the message access protocol interface.
Step s503, sending the converted feedback message to a message access protocol interface according to the access request ID.
Specifically, after the feedback message is converted, a corresponding message access protocol interface may be queried according to an access request ID carried in the feedback message, and after the message access protocol interface is queried, the converted feedback message is sent to the message access protocol interface.
In this embodiment, by carrying the access request ID in the feedback message, the correspondence between the feedback message and the message access protocol may be effectively identified, and the communication between the message access protocol and the blockchain network may be completed.

step s601, creating a received message queue, and storing the converted feedback messages in the received message queue according to the received time sequence;
specifically, a receive message queue may be created first, the receive message queue is independent from the transmit message queue, and after receiving and converting the feedback message, the converted feedback message may be stored in the receive message queue, and the storage sequence may be performed according to a receiving time sequence of the feedback message.
Step s602, sending the converted feedback message in the received message queue to a message access protocol interface according to the access request ID in sequence;
specifically, after the converted feedback messages are stored in order, the feedback messages may be sent to the message access protocol interface one by one according to a storage sequence, where the sending sequence is sent according to the first storage.
Specifically, before sending to the access protocol interface, the corresponding message access protocol interface may be queried according to the access request ID, and after querying the message access protocol interface, the converted feedback message may be sent to the corresponding message access interface.
Step s603, after the converted feedback message in the received message queue is sent, deleting the converted feedback message in the received message queue from the received message queue.
Specifically, after the converted feedback message in the received message queue is sent, the converted feedback message in the received message queue is deleted from the received message queue.
In this embodiment, by caching and sequentially sending the queues of the feedback messages, the loss of the messages due to the concurrence of the messages is avoided.
