When the parameter marker is [FromBody] receive less than application/json; Charset=utf-8 value can only receive the content-type=the value of the application/json,
How to deal with to receive application/json; Charset=utf-8 value??

CodePudding user response:

What is known as the "application/json; Charset=utf-8 value ", this is just setting data encoding format, in json, or in the XML, charset said character set format,

CodePudding user response:

Parameter is set to a string type, json format can be said,

1. The web.config need to configure the cross-domain

2. The front-end code

 
$(" # save "). Click (function () {
JQuery. Support. Cors=true; 
Var jdata={https://bbs.csdn.net/topics/"access_token" : "1231", "createtime" : "123", "expires_in" : "123"}; 
$. Ajax ({
Url: 'http://192.168.1.81:8492/api/values/testPost', 
Type: "POST", 
ContentType: "application/json; Charset=urf - 8 ",//the specified type is a json string, not a json object 
DataType: 'json, 
Data: JSON. Stringify (jdata), 
CrossDomain: true, 
Success: the function (returndata) {
Alert (JSON. Stringify (returndata)); 
}, 
Error: function (returndata) {
Alert (2); 
} 
}); 
}); 

3. The backend API

 
[HttpPost, HttpOptions] 
[ActionName (" testPost ")] 
Public ApiResult testPost () 
{
Try 
{
//receive 
The Stream inputstream=HttpContext. Current.. Request inputstream; 
Byte [] b=new byte [inputstream. Length]. 
Inputstream. Read (b, 0, (int) inputstream. Length); 
String inputstr=UTF8Encoding. And UTF8. Get string (b); 

Return new ApiResult 
{
IsError=false, 
Msg="success", 
PageCount=1, 
Result=inputstr 
}; 
} 
Catch Exception (err) 
{
Return new ApiResult 
{
IsError=true, 
Msg="failure", 
PageCount=1, 
Result="testPost" 
}; 
} 
}
