Background:

I sent the XML string in encoding= ' UTF-8 ' format, but at first I used the

Encoding.Unicode.GetBytes (strpost) or default or ASCII prompts for an error.

After modifying the character encoding format, success! So choose the right method based on the format you send.

Attention:

The function can send XML to the Ufida side, but the return information in the character is garbled.

This function can also achieve the same function but avoids the garbled problem

The detailed procedure and code are as follows:

1, create HttpWebRequest objects, HttpWebRequest can not be created directly through new, only through the WebRequest.Create (URL) way to obtain. WebRequest is a unified portal (Factory mode) that obtains some application-layer protocol objects, which determine the type of object that is ultimately created, based on the protocol of the parameters.

2, initialize the HttpWebRequest object, this process provides some HTTP request commonly used header attributes: Agentstring,contenttype, which agentstring more interesting, it is used to identify your browser name, By setting this property you can spoof the server you are a ie,firefox or even a Mac inside Safari. Many carefully designed sites will return code that is optimized for different browsers based on this value.

3, attach to the data to post to the server to the HttpWebRequest object, the process of attaching post data is special, it does not provide a property to user access, need to write HttpWebRequest object provided in a stream inside.

4, read the server's return information, read the server back, pay attention to return the data encoding, if we provide the type of decoding is not correct, will cause garbled, more common is utf-8 and gb2312. Typically, the site will encode it in the HTTP header, and if not, we can only determine how it is encoded by the statistical method that returns the binary value.
