The scheme provided by the specification is described below with reference to the accompanying drawings.
Fig. 1 is an architecture diagram of a system provided by an embodiment of the present disclosure, which may include a first terminal and a second terminal connected to each other, as shown in fig. 1. The first terminal and the second terminal are respectively operated with a first application and a second application. Wherein the first application and the second application may be mixed mode mobile applications (hybrid-apps), or web applications (web-apps) or native applications (native-apps). The first application may include a first application program and a first container. The second application may include a second application program and a second container. The first application program and the second application program are integrated with a subscription (Subscribers) function and a publishing (Publishers) function; the first container or the second container is integrated with a proxy (browser) function and a security function. The embodiment of the present application is described by taking an example in which the first container is integrated with an agent function and a security function, and the other cases are similar to these.
It should be noted that the subscription function and the publishing function integrated in the application program, and the proxy function and the security function integrated in the container may implement a subscription function, a publishing function, a proxy function, and a security function in a Message queue Telemetry Transport protocol (MQTT) or a WebSocket protocol, or may also be a subscription function, a publishing function, a proxy function, and a security function in other types of protocols, which is not limited in the embodiment of the present application.
The embodiment of the present specification provides a communication method, which can implement point-to-multipoint bidirectional communication between terminals, and the method is applied to a first terminal, and as shown in fig. 2, the processing procedure is as follows:
step 201, receiving, by a container, a publishing request sent by a first application program, which establishes a connection with the container, in the plurality of application programs.
The publishing request carries the message to be published and the first message topic corresponding to the message to be published.
In implementation, when the first terminal needs to communicate with other terminals, the first terminal may establish a connection with a container (i.e., a first container) having an agent function, which the first application includes, through an application (i.e., a first application) included in the first application installed in the first terminal. The first terminal may then send a publication request to the first container via the first application. The publishing request carries the message to be published and the first message topic corresponding to the message to be published. After receiving the publishing request sent by the first application program, the first container may parse the publishing request to obtain the message to be published carried in the publishing request and the first message topic corresponding to the message to be published.
The first application may be the first application in the first terminal, or may be an application in another terminal. The embodiment of the present application is described by taking a first application as an example of a first application in a first terminal, and other situations are similar to the first application.
Step 202, according to the subscription relationship between the application programs and the message topics pre-stored in the container, determining a second application program subscribing to the first message topic from the plurality of application programs.
In implementation, the first container may store a subscription relationship between the application program and the message topic in advance. The subscription relationship may be set by a technician, or may be established according to a subscription request sent by an application program. After the first container obtains the message to be published carried in the publication request sent by the first application program and the first message topic corresponding to the message to be published, a second application program which subscribes to the first message topic in the multiple application programs can be queried in the subscription relationship between the prestored application program and the message topic.
Step 203, sending a message to the terminal to which the second application program belongs through the container.
In an implementation, after the first container obtains the second application program subscribed to the first message topic, the message may be forwarded to the terminal to which the second application program belongs. In this way, after the first container receives the message that the first application program in the first terminal publishes to the first message topic, the first container can forward the message to the terminals to which all the second application programs subscribed to the first message topic belong, thereby realizing the point-to-multipoint communication between the first terminal and other terminals.
Optionally, the first terminal may further establish a subscription relationship between the application program and the message topic according to a subscription request sent by the first application program, where the detailed processing procedure is as follows:
step one, a subscription request sent by a third application program in a plurality of application programs is received through a container.
And the subscription request carries the second message topic.
In an implementation, the third application may be an application in the first terminal, or may be an application in another terminal. The embodiment of the present application is described by taking a first application program in a first terminal as an example, and other situations are similar to the first application program. When a first terminal needs to subscribe to a certain message topic, the first terminal can send a subscription request to a first container with a proxy function, which is contained in a first application installed in the first terminal, through the first application program contained in the first application. Wherein the subscription request carries a second message topic. After receiving the subscription request sent by the first application program, the first container may parse the subscription request to obtain a second message topic carried in the subscription request.
And step two, adding the subscription relationship between the third application program and the second message topic in the subscription relationship between the application program and the message topic pre-stored in the container.
In implementation, after the first container obtains the second message topic carried in the subscription request sent by the first application program, the subscription relationship between the first application program and the second message topic may be added in the pre-stored subscription relationship between the application program and the message topic. In this way, when the first container receives the message which is published to the second message topic by the terminal to which the other application program belongs, the message can be sent to the first terminal to which the first application program belongs according to the subscription relationship between the first application program and the second message topic.
Optionally, the first terminal may further establish a connection between the first application and the first container according to a connection request sent by the first application. The detailed treatment process is as follows:
step one, receiving a connection request sent by a first application program through a container.
The connection request carries an encrypted first password, and the encrypted first password is obtained by encrypting the first password by the first application program through the first private key.
In implementation, when the first terminal needs to communicate with other terminals, the first terminal needs to first establish a connection between the first application and the first container. The first terminal may transmit a connection request to a first container having a proxy function, which the first application includes, through a first application program included in a first application installed in the first terminal. The connection request carries an encrypted first password, and the encrypted first password is obtained by encrypting the first password by the first application program through the first private key. After receiving the connection request sent by the first application program, the first container may parse the connection request to obtain the encrypted first password carried in the connection request.
It should be noted that the encrypted first password may be transmitted as a parameter of a Uniform Resource Identifier (URI) in the connection request.
And step two, decrypting the encrypted first password according to a public key corresponding to a first private key stored in the container in advance to obtain the first password.
In implementation, after the first container obtains the encrypted first password carried in the connection request sent by the first application program, the first container may decrypt the encrypted first password according to a pre-stored public key corresponding to the first private key to obtain the first password.
And step three, determining a second password corresponding to the first application program according to the corresponding relation between the application program and the password stored in the container in advance.
In implementation, the first container may further store a correspondence between the application program and the password in advance. The password corresponding to the application program can be set by a technician or generated according to a preset password generation rule. After receiving the connection request sent by the first application program, the first container may query a second password corresponding to the first application program in a pre-stored correspondence between the application program and the password. After the first container obtains the first password and the second password, whether the first password and the second password are the same can be further judged. And if the first password is the same as the second password, executing the step four. And if the first password is different from the second password, executing a fifth step.
And step four, sending a connection success response to the first application program through the container so as to enable the first application program to establish connection with the container.
In an implementation, if the first password is the same as the second password, indicating that the first container is successfully authenticated to the first application, the first container may send a connection success response to the first application. In this way, the first application program can establish connection with the first container after receiving the connection success response sent by the first container.
And step five, sending a connection failure response to the first application program through the container.
In an implementation, if the first password is different from the second password, indicating that the first container failed to authenticate the first application, the first container may send a connection failure response to the first application.
Optionally, the first terminal may further obtain a password corresponding to the first application program according to a password obtaining request sent by the first application program. The detailed treatment process is as follows:
step one, a password acquisition request sent by a first application program is received through a container.
In implementation, when a first terminal needs to establish a connection between a first application and a first container, the first terminal may send a password acquisition request to the first container with an agent function, which is included in a first application installed in the first terminal, through the first application included in the first application.
And step two, acquiring a third password corresponding to the first application program through the container.
In implementation, after receiving a password obtaining request sent by a first application program, the first container may obtain a third password corresponding to the first application program. The way for the first container to obtain the third password corresponding to the first application program may be various, and the embodiment of the present application provides two possible implementation manners.
In the first embodiment, the third password corresponding to the first application program is determined according to the correspondence between the application program and the password stored in the container in advance.
In implementation, the first container may store a corresponding relationship between the application program and the password in advance, and the corresponding relationship may be set by a technician. After receiving the password acquisition request sent by the first application program, the first container may query a third password corresponding to the first application program in a pre-stored correspondence between the application program and the password.
In the second embodiment, a third password corresponding to the first application program is generated according to a preset password generation rule.
In an implementation, the first container may have a password generation rule stored therein in advance. The password generation rule may be set by a technician. After receiving the password acquisition request sent by the first application program, the first container may generate a third password corresponding to the first application program according to a preset password generation rule.
Optionally, after the first container generates the third password corresponding to the first application program according to the preset password generation rule, the first container may further store the corresponding relationship between the first application program and the third password in the container, so as to subsequently verify the first application program.
And step three, encrypting the third password according to a second private key stored in the container in advance to obtain the encrypted third password.
In implementation, after the first container obtains the third password corresponding to the first application program, the third password may be encrypted according to the pre-stored second private key to obtain the encrypted third password.
And step four, sending a password acquisition response to the first application program through the container.
And the password acquisition response carries the encrypted third password.
In implementation, after obtaining the encrypted third password, the first container may send a password obtaining response to the first application. And the password acquisition response carries the encrypted third password. Subsequently, after receiving the password acquisition response sent by the first container, the first application program may analyze the password acquisition response to obtain an encrypted third password carried in the password acquisition response. Then, the first application program may decrypt the encrypted third password according to the pre-stored public key corresponding to the second private key to obtain the third password, and send a connection request to the first container based on the third password to establish the connection.
