In step S205, the URL corresponding to the webpage is sent to the second terminal.

In a possible implementation manner, there may be one or more second terminals.

As an example of this embodiment, the user turns on the screen content sharing function of a smart phone B (first terminal). When it is detected that the screen content sharing mode is turned on, the Wi-Fi hotspot corresponding to the smart phone B is turned on (step S201), and the DNS request received by the smart phone B is hijacked to the smart phone B locally. Further, a screenshot command of the smart phone B is triggered to obtain a screenshot picture (step S202). Using the smart phone B as the server, the screenshot can be answered by the smart phone B to the devices connected to the Wi-Fi hotspot, such as A1 to A8 (second terminal) shown in FIG. 3 . For example, a smart phone A2 (second terminal) requests to access the Wi-Fi hotspot. When receiving the request to connect to the Wi-Fi hotspot, the smart phone B sends a web page authentication instruction to the smart phone A2 (step S203). Smartphone A2 generates a webpage authentication request after receiving the webpage authentication instruction, and sends the webpage authentication request to smartphone B. When smart phone B receives the web page authentication request, it generates a web page according to the screenshot (step S204), and sends the web address corresponding to the web page to smart phone A2 (step S205). The smart phone A2 can display the screenshot through the webpage.
