无法将Access-Control-Allow-Origin添加到我的WCF库项目中 [英] Could not add Access-Control-Allow-Origin to my WCF library Project

问题描述

我试图理解为什么这个叫ajax的电话不起作用

I'm trying to understand why this ajax called doesn't work

 $.ajax({
        type: 'GET',
        url: "http://localhost:8732/Design_Time_Addresses/InMotionGIT_NT.Address.Service/AddressService/json/capitalize",
        data: { streetAddress : JSON.stringify(streetAddress) , consumer :  JSON.stringify(consumer)} ,
        datatype: "jsonp",
        success: function (data) {
            $('body').append('<div>'+data.IDblah+' '+ data.prueba+'</div>');
            alert(data.IDblah);
        }

服务接收到的数据已正确接收，并且响应正确.为什么我做错了?

The service receive the data is correctly received and the response it's correct. Why am I doing wrong?

我尝试将此属性添加到称为的ajax中，但未成功crossDomain : true

I tried adding this property to the ajax called but without success crossDomain : true

[OperationContract()]
[WebInvoke(Method="GET", RequestFormat=WebMessageFormat.Json, ResponseFormat=WebMessageFormat.Json)]
public string Capitalize(StreetAddress streetAddress,ConsumerInformation consumer)

我得到的错误是常见的

 XMLHttpRequest cannot load Origin http://localhost:50816 is not allowed by Access-Control-Allow-Origin.

更新

我试图通过在我的App.config文件中添加配置来将标头添加到响应中，但是没有成功

I tried to add the header to the response by adding the configuracion in my App.config file but without success

<system.webServer>
<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
  </customHeaders>
</httpProtocol>
</system.webServer>

推荐答案

此链接将帮助您: http://enable- cors.org/

您需要在发送回客户端的响应中添加以下标头:

You need to add the following headers in your response that is sent back to the client:

//允许所有域

Access-Control-Allow-Origin: *

OR

//允许特定域

Access-Control-Allow-Origin: http://example.com:8080 http://foo.example.com
