In other instances, well-known features have not been set forth in detail in order not to obscure the invention.
Referring to fig. 1, the present invention provides a data distribution method based on a server, including the following steps: the server reads configuration data from a configuration database, wherein the content of the configuration data comprises a data main key, a numerical value and a version number; a client sends a data query request to the server, wherein the data query request comprises a data primary key; and the server obtains the numerical value and the version number of the data main key of the query request according to the configuration data query and issues the numerical value and the version number of the data main key to the client. Therefore, when the client inquires the data from the server, the primary key of the data is uploaded, and the server issues the corresponding data according to the primary key of the data as required, so that the network bandwidth occupied by data issuing is greatly reduced, the data transmission efficiency and the real-time performance are improved, and the security and confidentiality performance of the data are also improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating a server-based data distribution method according to an embodiment of the present invention. The data issuing method based on the server specifically comprises the following steps:
step S101: the server reads configuration data from a configuration database, wherein the content of the configuration data comprises a data main key, a numerical value and a version number;
in a specific implementation, referring to fig. 3, the server 200 is connected to a configuration database 300, where the configuration database 300 is used to store configuration data, and the content of the configuration data may include a data primary key, a numerical value, and a version number, for example, the configuration data includes: < key1, value1, ver1>, < key2, value2, ver2> and < key3, value3, ver3 >. Wherein, key1, key2 and key3 are data main keys of the three items of data respectively, value1, value2 and value3 are numerical values of the three items of data respectively, and ver1, ver2 and ver3 are version numbers of the three items of data respectively; the data key is used for uniquely identifying a data item attribute, the version number is the version of each data item, and actually, the version number is the modified timestamp of each data item.
The configuration database 300 stores configuration data in advance, that is, the data is configured according to the data main key, the numerical value and the version number and stored in the configuration database 300; after the server 200 is started, the server 200 reads the configuration data from the configuration database 300, that is, the server 200 loads the configuration data from the configuration database 300 into the local service memory to wait for the data query request of the client 100.
Step S102: a client sends a data query request to the server, wherein the data query request comprises a data primary key;
in specific implementation, when a user needs to query some configuration data information, a data query request is sent to the server 200 through the client 100, where the data query request includes a client ID and a data primary key; the data primary key can be used for uniquely identifying a data item attribute, for example, in an application of a caller identification scene, the data primary key is a caller telephone number needing to be inquired, namely, the client packs a client ID and the inquired caller telephone number into an inquiry request and sends the inquiry request to the server.
Step S103: the server queries according to the configuration data to obtain the numerical value and the version number of the data main key of the query request;
in specific implementation, after receiving a data query request sent by the client 100, the server 200 obtains a data primary key according to the data query request, and queries whether the data primary key exists in configuration data according to the data primary key, if so, obtains a numerical value and a version number of the data; if not, the query failure is fed back to the client 100. For example, in an application of a caller id display scenario, the server queries, according to the caller id, a number attribution and operator information corresponding to the caller id.
Step S104: the server records the data main key and the version number in a user data database;
in a specific implementation, please refer to fig. 3, the server 200 is further connected with a user data database 400, the user data database 400 is used for recording data primary keys and version numbers issued to the clients, and when the server queries values value1 and version number ver1 corresponding to the data primary key1 of the client ID1, a key1 and a corresponding version ver1 are added to the data record issued by the client ID1, that is, the ID 1: < key1, ver1> was written to user data database 400.
Step S105: the server transmits the numerical value and the version number of the data main key to the client;
in a specific implementation, the server 200 issues the value1 and the version number ver1 corresponding to the data primary key1 to the client ID1, that is, returns data < key1, value1, ver1> to the client ID 1. The client ID1 receives and stores the value and version number sent by the server, so as to prompt the next data update.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a server-based data distribution method according to another embodiment of the present invention. In this embodiment, when the configuration data queried by the client is updated, that is, the value and the version number corresponding to the data primary key are changed, incremental information is generated, and the server issues the incremental information to the client. The server-based data issuing method specifically comprises the following steps:
step S201: the server reads configuration data from a configuration database, wherein the content of the configuration data comprises a data main key, a numerical value and a version number;
in a specific implementation, please refer to fig. 5, when the information corresponding to a certain data primary key is updated and changed, for example, a background operator modifies the information of the data primary key1, at this time, the version of the data primary key1 added to the configuration database 300 is changed from ver1 to ver4, that is, the configuration data corresponding to the updated data primary key is < key1, value1, ver4 >.
Step S202: a client sends a data query request to the server, wherein the data query request comprises a data main key and a maximum version number corresponding to the data main key;
in specific implementation, the client ID1 sends a data query request to the server, where the data query request includes a data primary key1 and a version number ver1 corresponding to the data primary key 1.
Step S203: the server reads a version number corresponding to the data primary key of the client from a user data database, compares whether the version number corresponding to the data primary key in the user data database is smaller than the version number corresponding to the data primary key in the configuration data, and if not, performs step S204; if yes, go to step S205;
during specific implementation, the server firstly searches whether a client ID1 has a distribution record in a user data database, and reads the maximum version number corresponding to the data primary key distributed to the client; and then, the server compares whether the maximum version number corresponding to the issued data primary key is smaller than the version number corresponding to the data primary key in the configuration data DB, if so, the server indicates that the corresponding information of the data primary key is updated and needs to issue updated data.
Step S204: the server issues the data primary key, the numerical value and the version number in the user data database to the client under the condition that the maximum version number corresponding to the data primary key in the data query request is judged to be smaller than the version number corresponding to the data primary key in the user data database;
in specific implementation, after the server 200 determines in step S203 that the version number corresponding to the data primary key in the configuration data is not updated, in order to ensure that the client receives the delivered data, the server 200 further compares whether the maximum version number corresponding to the data primary key in the data query request is smaller than the version number corresponding to the data primary key in the user data database 400, if so, the server 200 delivers all the data having the version number larger than the maximum version number in the user data database 400 to the client 100, and updates the version number corresponding to the data primary key in the user data database 400.
Step S205: and the server records the data primary key and the version number in the configuration data in a user data database, and issues the value and the version number of the data primary key in the configuration data to the client.
In a specific implementation, when it is found that information corresponding to the data primary key in the configuration data is updated, the server 200 issues the updated value1 and version number ver4 corresponding to the data primary key1 to the client ID1, that is, returns data < key1, value1, ver4> to the client ID 1. The client ID1 receives and stores the value and version number sent by the server, so as to prompt the next data update.
It should be noted that, for a module or software, the client does not need to store the version of each piece of primary key data, but only stores one overall version, and the server caches the version of the primary key that has been issued to the client.
