Question

HTML Jquery Ajax HTML页面正在http://domain2.application.net/index.html中运行。

$.ajax({
                type: "POST",
                url: "http://domain.service.net/Service.svc/AddUsers",
                contentType: 'application/json; charset=utf-8',
                data: dataToSend,
                dataType: 'json',
        async: false,

                success: function (response) {        
                }
            });

WCF服务

[OperationContract]
[WebInvoke(UriTemplate = "", Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
public void AddUsers(string name, string email)
{            
    //Add user information to database          
}

调用AddUser服务时出现以下错误的错误

> XMLHttpRequest cannot load
> http://domain.service.net/Service.svc/AddUsers. No
> 'Access-Control-Allow-Origin' header is present on the requested
> resource. Origin 'http://domain2.application.net' is therefore not
> allowed access.

如果您查看here，您会发现问题与后端有关，因此为了解决这个问题，您必须向WCF项目添加几个帮助程序，并且还要显式修改web.config

的Web服务端点

<crossOriginResourceSharingBehavior />

可能的解决方案是here at this site。

希望它有所帮助！祝世界CORS好运！

错误WCF - 请求的资源上没有“Access-Control-Allow-Origin”标头
