1. My environment: vs2005, without SP1 patch, cannot create web applications, only websites; jquery version 1.5.1

2. Relevant configurations in web.config

3. How to write jquery’s Post data

Copy code The code is as follows:

 
$(document).ready(function (){ 
$("#btnSend").click(function(){ 
$ .ajax({ 
type: "POST", 
url: "PrecisionAHandle.ashx", 
contentType: "application/x-www-form-urlencoded; charset=UTF-8", 
 data: { "StudentId": $("#LblStudentId").attr("innerText"),"StudentName": $("#LblStudentName").attr("innerText"),"StudentAge": $("#txtStudentAge ").attr("value")}, 
success: function(html){ 
$("#TabContainer").html(html); 
} 
}); 
 }); 
}); 

where StudentName is Chinese

4. How to write parameters in .ashx file

string strStudentName = context. Request.Params["StudentName"];
Note: If there is no contentType: "application/x-www-form-urlencoded; charset=UTF-8", context.Request.Params["StudentName"] will be garbled.
By tracking context.Request.ContentEncoding in .ashx, it can be seen that the data posted by jquery uses gb2312 encoding. Maybe context.Request uses utf-8 for decoding by default when receiving data, but jquery uses utf-8 to decode the data in the Post data. However, utf-8 was not used, which caused the context.Request.Params["StudentName"] of .ashx to be displayed as garbled characters.
Strange phenomenon:
Phenomenon 1: Without adding contentType: "application/x-www-form-urlencoded; charset=UTF-8", use the following in the .ashx file The statement can display the string correctly:

Copy the code The code is as follows:

 
StreamReader steamRd = new StreamReader(HttpContext.Current.Request.InputStream); 
string strPostData = steamRd .ReadToEnd(); 
strPostData =HttpUtility.UrlDecode(strPostData, Encoding.GetEncoding("utf-8")); 

Phenomenon 2: After changing the relevant configuration in web.config to

, regardless of whether it is added contentType: "application/x-www-form-urlencoded; charset=UTF-8", the parameters received by the .ashx file in the background are still garbled. After modifying web.config, the website compiles very slowly and runs very slowly.
