The terminal device as claimed in claim 10, wherein, A reverse proxy module, further adapted to receive a network test request sent by an application server through the network tunnel; wherein, the application server sends the network test request to the second port on the main proxy server; A reverse proxy module, adapted to perform corresponding network access operations according to the network test request, and feed back the results of the network access operations through the network tunnel; wherein, the application server obtains the information from the main proxy server. The result of the network access operation is obtained from the second port. 12. The terminal device as claimed in claim 10, wherein, A network tunnel establishment module, adapted to establish a network tunnel between the first port and the second port of the main proxy server according to the connection parameters; wherein the connection parameters include: the login account and password of the terminal device, the main proxy server's The WAN IP address and the port number of the second port, and the port number of the first port of the terminal device that is started. 13. The terminal device as claimed in claim 11, wherein, The network tunnel is established. The module is an SSH client; The reverse proxy module is a Squid server. 14. The terminal device according to claim 10, wherein the terminal device further includes: an automatic reconnection module, The automatic reconnection module is suitable for when the established network tunnel is disconnected, the automatic reconnection module starts the network tunnel establishment module, and the network tunnel establishment module remaps the first port to the network tunnel according to the connection parameters. On the second port on the primary proxy server, re-establish the network tunnel. 15. The terminal device as claimed in claim 13, wherein, The automatic reconnection module is the AUTOS SH client. 16. The terminal device according to claim 10, wherein the network test request includes: a network speed test request or a network quality test request; When the network test request is a network quality test request, the reverse proxy module is adapted to send a test data packet to the destination server and wait for feedback from the destination server, based on the sending time of the test data packet and the test data packet feedback at the reception time, calculate the network delay with the destination server; and calculate the network quality with the destination server based on the number of sent test data packets and the number of feedback test data packets; or, When the network test request is a network speed test request, the reverse proxy module is suitable for downloading a data packet of a specified size from the destination server. According to the size of the data packet and the time required to complete the download, calculate the distance between the data packet and the destination server. download speed. 17. A system for implementing network testing based on reverse proxy, wherein the system includes: a main proxy server with a WAN IP address and the terminal device as claimed in claim 7. 18. The system of claim 17, wherein, The main proxy server is deployed with a network tunnel establishment server, The main proxy server is adapted to establish a network tunnel between the server and the terminal device through the network tunnel establishment server; send a network test request to the terminal device, and receive the corresponding network test request returned by the terminal device according to the network test request. Network access to access operations The result of the operation. 19. The system of claim 17, wherein the system further includes: an application server; The application server is adapted to send a network test request to the second port on the main proxy server through the network tunnel; causing the terminal device to perform corresponding network access operations according to the network test request, and access the network to The results of the operation are fed back through the network tunnel'; The application server is adapted to obtain the result of the network access operation from the second port on the main proxy server. 20. A computer program, including computer readable code, which when the computer readable code is run on a server, causes the server to execute the method according to any one of claims 19. 21. A computer-readable medium in which the computer program according to claim 20 is stored.
