Hi All,

I have a web api which has a Post method in it.
So from another webpage i'm posting json data to this API using jquery ajax as below -

JavaScript

$.ajax({  
    type: "POST",  
    url: "http://localhost:4046/Values/Mymethods",  
    data: jsondata,  
    dataType: 'json'  
}).complete(function (msg) {  
});

This is working fine and getting the result from API.

The issue happens when I add an custom header in to this as below -

JavaScript

$.ajax({  
             type: "POST",  
             url: "http://localhost:4046/Values/Mymethods",  
             data: jsondata,  
             dataType: 'json',  
             header: { 'Token': 'asasaad' }  
         }).complete(function (msg) {  
         });

Now this is throwing cross domain error like below -

XMLHttpRequest cannot load http://localhost:4046/Values/My methods. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:2769' is therefore not allowed access. The response had HTTP status code 405.

I have provided <add name="Access-Control-Allow-Origin" value="*" /> header in web.config

I have created Web API in MVC 4.

Hope someone has got an solution for this.

Thanks in advance.

What I have tried:

Tried providing

<add name="Access-Control-Allow-Origin" value="*" /> header in web.config

In which config? You have a client project and an API project. It needs to go in the API project and there are additional access settings that allow the use of custom headers so you probably need to add that too.

As i'm not using web API 2, i'm not able to use CORS. Everything is working fine, if custom header is not passed.Issue is happening when I pass this header.

We can send cross domain AJAX requests using JSONP. Below is the simple JSONP Request:

$.ajax({  
             type: "POST",  
             url: "http://localhost:4046/Values/Mymethods",  
             data: jsondata,  
             dataType: 'jsonp',  
             header: { 'Token': 'asasaad' }  
         }).complete(function (msg) {  
         });
