  FIG. 7 is a flowchart of a method by which an operating system according to an embodiment of the present invention feeds back a communication link. As shown in FIG. 7, the method includes steps S702 to S716.

  Step S702, the caller inputs an application identifier (eg, application).

  In step S704, when the system receives a call request for detecting a link, the system calls a basic API of the system based on the input parameter application identifier to retrieve and obtain the user identifier of the application. When the user identifier of the application is found, step S706 is performed. If the user identifier of the application is not found, the process proceeds to step S716.

  In step S706, the netstat command is executed, and all links whose statuses on the terminal are “SYN-SENT” and “ESTABLISHED” are found as valid links. The link information may include a local address, a local port, a partner address, a partner port, and the like.

  Step S708, the TCP file is analyzed.

  In the Android system, the TCP file is located in the / proc / net / directory of the system.

  The / proc / net / tcp file records the status of all TCP connections in Internet Protocol version 4 (IPV4). Read the file using the cat / proc / net / tcp command. Each line in the TCP file represents information of one IPV4 link. When a local port and a user identifier are obtained from each line, a direct correspondence between the local port and the user identifier is obtained.

  The / proc / net / tcp6 file records the status of all TCP connections in Internet Protocol version 6 (IPV6). Read the file using the cat / proc / net / tcp6 command. Each line in the TCP6 file represents information of one IPV6 link. When a local port and a user identifier are acquired from each line, a direct correspondence between the local port and the user identifier is acquired.

  In step S710, the current analysis result is filtered by the user identifier of the application to obtain a local port used for the designated application. If a local port is found, the process proceeds to step S712. If not, the process proceeds to step S716. .

  In step S712, based on the user identifier and the local port, the communication link of the designated application can be estimated, and if the communication link of the application is found, the process proceeds to step S714.

  In step S714, the communication link of the application is fed back and the process ends.

  In step S716, information indicating that the link is empty is fed back.

  As can be seen from the above, according to the present invention, the current true effective link of the application can be detected in real time, and there is a technical effect of improving the accuracy of link detection and reducing development costs.

  Of course, those skilled in the art will recognize that each module or step of the present invention described above is implemented by a general-purpose computing device and may be integrated into a single computing device or distributed over a network composed of a plurality of computing devices. Or may be implemented by computing device executable program code so that it can be stored in a storage device and executed by a computing device, and in some cases, the steps shown or described It may be executed in an order different from the order here, and each of them may be produced in each integrated circuit module, or a plurality of modules or steps thereof may be produced in a single integrated circuit module. Should be understood. Therefore, the present invention is not limited to a specific combination of hardware and software.
