将已发布的JSON数据发布到Web API的问题 [英] Issue with posted JSON data to web API

问题描述

我有一个网页，可以将数据发布到Web API。

ajax函数如下。

Hi,
I have a web page which posts data to an Web API.
The ajax function is as follows.

var jsondata = { "comparisionCalculatorReq": { "transactionType": "None", "fundName": "Myfund", "annualizedReturn": "10", "frequency": "Monthly"} };  
  
$.ajax({  
type: "POST",  
url: "http://localhost:1101/Mypost/PostDataAPI",  
dataType: 'json',  
data: jsondata  
}).done(function (msg) {  
alert(msg);  
});  

在我的Web API控制器中，我有一个如下方法

In my Web API controller i have a method as below

[ActionName("PostDataAPI")]  
       public string PostDataAPI(JSONdata obj)  
       {  
           try  
           {  
               string k = obj.transactionType;  
               return k;  
           }  
           catch (Exception err)  
           {  
               throw err;  
           }  
       }  

JSONdata类位于以下

The JSONdata class is below

public class JSONdata  
   {  
       public string transactionType { get; set; }  
       public string fundName { get; set; }  
       public string annualizedReturn { get; set; }  
       public string frequency { get; set; }  
   }  

问题是，我得到的是transactionType的空值我的控制器。



如果json数据在ajax中这样传递，

Problem is that, I'm getting null value for transactionType in my controller.

If the json data is passed like this in ajax,

var jsondata={ "transactionType": "None", "fundName": "Myfund", "annualizedReturn": "10", "frequency": "Monthly"};

然后所有的值都是正确的。
请为此提供解决方案。



我尝试过：



我试过制作如下的JSONdata类，但是它仍然为每个值返回null

then all the values are got correct.
Please provide a solution for this.

What I have tried:

I have tried making the JSONdata class as below, but still it is returning null for every values

public class JSONdata  
   {  
       public object comparisionCalculatorReq { get; set; }
       public string transactionType { get; set; }  
       public string fundName { get; set; }  
       public string annualizedReturn { get; set; }  
       public string frequency { get; set; }  
   }  

推荐答案

.ajax（{
type： POST，
url： http：// localhost：1101 / Mypost / PostDataAPI，
dataType：' json'，
数据：jsondata
}）。done（ function （msg）{
alert（msg） ）;
}）;

.ajax({ type: "POST", url: "http://localhost:1101/Mypost/PostDataAPI", dataType: 'json', data: jsondata }).done(function (msg) { alert(msg); });

在我的Web API控制器中，我有一个如下方法

[ActionName("PostDataAPI")]  
       public string PostDataAPI(JSONdata obj)  
       {  
           try  
           {  
               string k = obj.transactionType;  
               return k;  
           }  
           catch (Exception err)  
           {  
               throw err;  
           }  
       }  

JSONdata类位于以下

The JSONdata class is below

public class JSONdata  
   {  
       public string transactionType { get; set; }  
       public string fundName { get; set; }  
       public string annualizedReturn { get; set; }  
       public string frequency { get; set; }  
   }

我修改了你的ajax代码：

I modified your ajax code:

var jsondata = { "comparisionCalculatorReq": { "transactionType": "None", "fundName": "Myfund", "annualizedReturn": "10", "frequency": "Monthly"} };

.ajax（{
type： < span class =c ode-string> POST，
url： http：// localhost：1101 / Mypost / PostDataAPI，
contentType： application / json; charset = utf-8，
dataType：' json'，
数据： JSON .stringify（jsondata）
}）。done（ function （ msg）{
alert（msg）;
}）;

.ajax({ type: "POST", url: "http://localhost:1101/Mypost/PostDataAPI", contentType:"application/json; charset=utf-8", dataType: 'json', data: JSON.stringify(jsondata) }).done(function (msg) { alert(msg); });
