Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Under the scenes of testing terminal equipment and the like, the connecting end is required to be connected to one or more terminals for testing.
Taking a terminal as an android device as an example, in the device connection system shown in fig. 3, when a tester performs a test by controlling a plurality of android devices 2 at a test front end 4 (for example, a PC end), a test method may be:
the testing front end 4 accesses the server end 3 to obtain the device information and address information of the accessible android device based on the http protocol, the testing front end 4 establishes a webSocket communication (the webSocket communication is a protocol for performing full duplex communication on a single TCP connection) with the android device connection end 1 (for example, a PC or a server with an agent installed therein), the android device connection end 1 accesses the agent end on the android device corresponding to the device information according to the device information and address information of the android device 2 to be accessed, which are sent by the testing front end 4, the android device connection end 1 and the android device 2 can be subjected to socket communication in advance through a serial port, a USB or a wireless mode (for example, WiFi or a mobile network) connection, then a tester can send a request or a command to the android device by using a testing tool, and after the android device 2 receives the command or the request, and the agent on the android device 2 analyzes the commands, and then the agent on the android device 2 issues the analyzed commands to the commands which can be identified by each functional module of the mobile phone, and calls the corresponding functional module to simulate operation.
After the operation is completed, the android device 2 can return some target information, the agent on the android device 2 can grab the target information, then the target information is sent to the server end 3 based on the http protocol through the android device connecting end 1 in sequence, so that the testing front end 4 obtains the target information through accessing the server end 3, or the android device connecting end 1 directly sends the target information back to the testing front end 4 through websocket communication, and thus, a complete mobile phone automatic test is completed. Further, the android devices can be controlled by means of MMI _ command (at command), i.e., each android device is provided with a responsive interface.
When a target device (i.e., a certain android device 2) does not receive an access from a target front end (i.e., a certain test front end 4) for a long time, the target front end cannot access the target device to obtain corresponding device information or perform device operation due to the problem that a network connection established between the target device and the android device connection end through a command adb connect ip: port is unstable or closed.
In order to overcome the above problem, fig. 1 provides a method for connecting to a device according to an embodiment of the present application, including the following steps S1 to S4:
step S1, an access request of the target front end is received, where the access request carries target device information of a target device to be accessed by the target front end and first address information of the target device.
The method for connecting to a device in this embodiment may be applied to a scenario in which the device connection end accesses the terminal device, as shown in fig. 3, the method for connecting to a device may be executed by the device connection end (for example, a PC end installed with an agent).
The device connection end can determine that the device to be accessed by the target front end currently is the target device. The target device can be an android device which is connected with the device connection end through an adb connect ip execution command, and then an agent at the device connection end can access the android device.
And the device connecting end can disconnect the network connection with the target device when the target front end is determined to need to access the target device. For example, the device connection end may disconnect the connection between the interfaces corresponding to the target device according to the address information of the target device, so as to achieve the purpose of disconnecting the network connection with the target device.
The target device information may include, but is not limited to: the mac address of the target device, the model of the device, the brand of the device, the system version number, the device number and the like are used for representing information of each attribute of the target device.
The device connection may receive an access request from the target front-end, where the access request may be a request sent by the target front-end when accessing the target device. The access request may carry destination device information and second address information of the destination device. The target device information and the second address information may be pulled by the target front end from the target back end.
The target backend may store device information of each device and address information (e.g., IP address and port number) in advance. For the target device, the target backend stores target device information of the target device and the second address information.
When a user needs to access information on a target device through a target front end, the target front end may first pull information required for accessing the target device from a target back end, which may include but is not limited to: address information (e.g., IP address and port number) of a device connection end connected to the destination device, destination device information of the destination device, and second address information.
The target front end can establish connection with the equipment connecting end by using address information of the equipment connecting end, for example, the target front end establishes connection with the equipment connecting end through websocket; generating an access request according to the pulled target equipment information and the second address information; and sends the access request to the device connection terminal through the connection with the device connection terminal.
Further, the step S1 of disconnecting the network connection with the target device may be executed before the target front end starts to access the target device each time.
And step S2, disconnecting the network connection with the target device according to the first address information.
After the device connecting end acquires the access request, analyzing to obtain first address information in the access request, and then enabling the agent at the device connecting end to disconnect the network connection between the target devices corresponding to the first address information according to the first address information; furthermore, when the address information of the target front end is changed, when disconnection is performed, according to the disconnection failure information, it can be determined that the device connection end is disconnected from the target front end.
In summary, according to the method in this embodiment, the connection with the target device can be quickly disconnected based on the request of the target front end, so that an unstable connection state with the target front end can be disconnected, and the network connection stability can be improved by reconnecting with the target device at a later stage.
Step S3, reestablishing the network connection with the target device according to the second address information of the target device.
The second address information may include, but is not limited to: IP address information and port number of the target device.
Each target device has second address information uniquely corresponding to the target device; when the IP address and the port number of the target equipment are not changed, the equipment connecting end can reestablish network connection with the target equipment according to the IP address and the port number of the target equipment; when the IP address and the port number of the target device change, the device connection end cannot establish a network connection with the target device based on the original second address information.
In step S4, the target device is accessed through the reestablished network connection.
After the network connection between the device connection end and the target device is established, the agent of the device connection end can access the target device, so that the target front end can also access the target device through the device connection end.
By the method in the embodiment, before the target device is accessed, the network connection between the device connecting end and the target device is disconnected, and then the network connection between the device connecting end and the target device is established, so that the situation that the network connection between the device connecting end and the target device is unstable or closed due to the fact that the target device is not accessed through the device connecting end for a long time before disconnection can be avoided, and the target device can be stably accessed through the device connecting end.
In some embodiments, as the method mentioned above, the step S3 of reestablishing the network connection with the target device according to the second address information of the target device includes the following steps S31:
step S31, reestablishing the network connection with the target device according to the first address information, wherein the second address information is the first address information.
As can be seen from step S11 in the foregoing embodiment, the first address information is address information corresponding to the target device carried in the access request of the target front end, and therefore, when the device connection end does not change the address information after disconnecting the network connection with the target device, the network connection with the target device may be reestablished based on the first address information. The first address information may be read from a local side for storing the access request.
In an optional implementation manner of this embodiment, a storage location for storing or caching the access request may be disposed in the device connection end, and after receiving the access request, the access request may be stored in the storage location; and after the network connection with the target device is disconnected, the access request is read from the storage position again, and the first address information in the access request is obtained.
In another optional implementation manner of this embodiment, historical device information and historical address information of a historical device that has executed disconnection may also be recorded, and stored in a related log according to a time sequence; and then, inquiring the log to obtain first address information of the target device which has recently executed the disconnection operation and is not connected.
After the agent of the device connection end acquires the first address information, the network connection with the target device can be reestablished according to the first address information.
By the method in the embodiment, the first address information of the target device needing to be reconnected can be quickly inquired and obtained at the local end, so that the speed of establishing the connection with the target device is improved, the target front end can access the target device more quickly, and the user experience is improved.
In some embodiments, as the method mentioned above, the step S3 of reestablishing the network connection with the target device according to the second address information of the target device includes the following steps S32:
step S32, obtaining second address information corresponding to the target device information by querying the target backend, where the target backend stores the target device information and the second address information that are set correspondingly in advance.
The second address information is address information which is stored on the back end of the target and corresponds to the target equipment information; and the target back end stores the equipment information and the address information in a one-to-one correspondence manner according to the equipment information and the address information corresponding to each equipment.
Therefore, the agent connected to the device can query the target back end for the corresponding second address information based on the target device information.
Furthermore, the address of the target device is changed; and after the address of the target device is changed, the target device can transmit the address information corresponding to the changed address to the target backend, so that the target backend can update the second address information in real time according to the latest address information. Furthermore, when the target back end cannot establish network connection with the target equipment through the first address information of the local end, the target back end can inquire the target back end, and try to establish connection with the target equipment again according to the inquired second address information; therefore, when the address information of the target device is updated, the network connection with the target device can still be established.
On the other hand, before the network connection between the device connection terminal and the target device is disconnected, the connection state between the target device and the device connection terminal cached by the target front end is most likely not up-to-date; therefore, the connection state of the cache indicates that the connection end of the target device and the device is connected, but actually, the connection end of the target device and the device is disconnected, that is, a false connection state exists; therefore, in this case, if the test front end needs to access the target device, the access may not be performed.
For example: when the false connection problem occurs between the device connection end and the device, due to some reasons, such as shutdown of the device and unstable network, the connection is finally disconnected, the connection is truly disconnected due to the change of the device IP, and the connection cannot be reestablished, the agent of the device connection end needs to be detected in time and reported to the server end (i.e., the target back end).
As shown in fig. 2, in some embodiments, to solve the above technical problem, the method further includes steps S5 to S8 as follows:
step S5, sending a heartbeat message to the device to be determined, where the currently cached state information of the device to be determined is used to represent that the device to be determined is in a connected state.
The method in this embodiment may be applied to a scenario in which the device connection end tests the connection state of the terminal device, and the test method may be executed by the device connection end (for example, a PC end installed with an agent).
Specifically, the device to be determined may be any device that needs to perform the determination of the status information and is connected to the device connection terminal.
The heartbeat message is generated by the agent of the device connection end and is used for sending the message to the device end to be determined, and the agent of the device connection end can determine whether and when the network connection with the device end to be determined is interrupted according to the feedback of the device end to be determined.
The agent of the device connection end can determine the address information of each device to be determined, and then sends heartbeat messages to the devices to be determined according to the address information.
And step S6, reestablishing the connection with the device to be determined under the condition that the response of the device to be determined to the heartbeat message meets the preset reconnection condition.
Specifically, the response of the device to be determined to the message may be, under normal circumstances: feeding back a confirmation message to an agent at the connection end of the equipment when the equipment to be determined receives a heartbeat message; therefore, the condition that the response of the device to be determined to the heartbeat message satisfies the preset reconnection condition may be that the acknowledgement message of the device to be determined to the heartbeat message is not received, or the number of the received acknowledgement messages of the device to be determined to the heartbeat message is far less than the number of the sent heartbeat messages.
In this case, it is described that the network connection between the device connection end and the device to be determined is unstable, or the network is disconnected, and since the heartbeat message is actively sent by the agent at the device connection end, it is caused that the heartbeat message can determine the address information of the device to be determined in which the abnormality occurs; therefore, the connection with the equipment to be determined can be reestablished according to the address information of the equipment to be determined with the abnormality.
In some embodiments, as in the method above, the predetermined reconnection condition comprises one of:
the method comprises the following steps that 1, equipment to be determined continuously does not respond to a first preset number of heartbeat messages; the first preset number may be preset number information.
For example, when the first preset number is 10, the condition 1 is: the device to be determined does not continuously feed back confirmation messages for the 10 heartbeat messages.
For example, when the second predetermined number is 10 and the third predetermined number is 5, the condition 2 is: the device to be determined does not feed back acknowledgement messages for at least 5 of the 10 heartbeat messages.
Step S7, in a case that the connection with the device to be determined cannot be established, generating target offline information, where the target offline information is used to represent that the device to be determined is in an offline state.
Specifically, the target offline information may include, but is not limited to: the device information and the address information of the device to be determined and the offline state information used for indicating that the device to be determined is in the offline state.
When the IP address or port of the device to be determined is changed, which results in that the network connection with the device to be determined cannot be established according to step S6, target offline information representing that the device to be determined cannot be connected and is in an offline state is generated.
Step S8, sending the target offline information to the target back end, so that the target back end marks the device to be determined as an offline device according to the target offline information.
Specifically, since the network connection is pre-established between the device connection end and the target back end, the agent of the device connection end can send the target offline information to the target back end according to the network connection between the device connection end and the target back end, and after the target back end receives the target offline information, the device information and the offline state information of the device to be determined in the target offline information can be obtained through analysis, and then the device to be determined is marked as the offline device according to the device information and the offline state information.
After the target back end marks the device to be determined as the offline device, and the target front end synchronizes the data of the target back end, the device to be determined can be determined to be in the offline state, and further, the device to be determined can be prevented from being accessed.
By the method in the embodiment, whether reconnection is performed can be judged in real time according to the response of the heartbeat message of the equipment to be determined so as to ensure the stability of network connection in real time; meanwhile, the condition that the access of the test front end to the target equipment is failed through the equipment connecting end due to the false connection state between the target equipment and the equipment connecting end can be avoided.
In some embodiments, as in the previous method, the method further comprises steps S91 to S94 as follows:
step S91, receiving a connection request sent by the device to be connected, where the connection request carries current address information of the device to be connected.
The method in this embodiment may be applied to a scenario in which the device connection end and the terminal device initially establish a connection, and the method of establishing a connection may be executed by the device connection end (for example, a PC end installed with an agent).
Specifically, the device to be connected may be a device that needs to establish a network connection with the device connection end and receive access from the target front end.
The connection request may include the current address information of the device to be connected and the related information of the agent for requesting to connect to the device connection terminal.
Further, the device to be connected may send a connection request to the target back end in advance, so that the target back end receives the request according to the agent at the connection end of the connection request management and control device.
And step S92, establishing network connection with the target device according to the current address information.
Specifically, after the current address information in the connection request is obtained, a command adb connect ip can be executed according to the current address information, wherein the port establishes network connection between the device connection end and the device to be connected.
Step S93, device information of the device to be connected is acquired.
Specifically, after the network connection between the device connection end and the device to be connected is established, the device information of the device to be connected may be acquired, including but not limited to: mac address, model of equipment, brand of equipment, system version number and the like.
And step S94, sending the device information and the current address information of the device to be connected to the target back end for storage.
Specifically, after the agent of the device connection end acquires the device information, the device information and the current address information can be sent to the target back end for storage based on network connection with the target back end, and when any front end capable of accessing the target back end is accessed, the device information and the current address information can be acquired from the target back end and displayed.
For example: when the android terminal (i.e. the device to be connected) is connected with the device through a certain network (e.g. a WiFi network) and is in the same network environment, an HTTP request can be made to a server (i.e. a target back end) to request to connect to the device connection end, and after the HTTP request is received by the server, the device connection end can be controlled to conduct active search, and after the device to be connected is searched, connection with the device to be connected is established. Then, the device to be connected can send a request to the agent of the device connection end through WiFi, the agent of the device connection end can obtain the IP address and the port of the mobile end, a command adb connect IP can be executed, the port can connect the android terminal with the device connection end, the device connection end can obtain specific information of the device after connection is established, such as the mac address, the model of the device, the brand of the device, the system version number and other information, and then the agent of the device connection end can send the information to the server end. When the target front end receives the user access, the target front end can obtain the information from the server end and display the information.
By the method in the embodiment, the device information and the current address information of the device to be connected, which is accessed to the device connection end for the first time, can be acquired, and after the device information and the current address information are transmitted to the target back end, when any front end connected with the target back end is accessed, the device information and the current address information can be acquired from the target back end and displayed, so that a user can select the device to be accessed according to the displayed information.
