Summary of the Automatic posting Program

Recently, I have made automatic logon and posting for dozens of major sites. In fact, the principle is simple, that is, many sites need to adjust the parameters when posting, some are dynamic parameters, some are upload forms.

I don't know whether it is unfamiliar with C # or poor encapsulation of httpwebrequest. I always encounter problems, but it will be okay if I rewrite the same function httpclient once.

The biggest problem in the past few days is that if the website is originally an upload form and the form is also used in C #, an error will certainly occur. Using a Java non-upload form is okay.

 

In addition, the post parameter in C # must use urlencode. Otherwise, many exceptions may occur ..
