The code I searched on Baidu for saving remote images to the local area seems a bit difficult to use, and there is no ready-made and complete code that I can't understand.
I extracted some functions from the SNA news gathering system For 3.62 (programmed by: ansir) and used them, which is relatively simple and easy to use.
The following is the function
program code
Copy the code code as follows:
