The data download Tool Based on g_soap has a transmission speed of only kb and needs to be improved.

The code is incomplete. It is obtained from the broken hard disk... Of course, we can still make an example. I will not introduce it in detail. I believe that anyone who has some programming experience can easily understand it.
