Loadrunder Script--web_submit_data Implementation submit POST request

The Web_link () and Web_url () functions are page-accessible functions that implement the Get method in HTTP requests, and use the Web_submit_form or Web_submit_data () function if you need to implement the Post method. When the request is special, Vugen cannot use the above 4 functions, the Web_custom_request () function is used.
