Question

我无法拨打wcf。

我正在使用：

wcf
visual studio cordova

有人帮助我吗？

界面定义

[ServiceContract]
public interface IService
{
        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        string GetAddNumbers(int a, int b);
}

服务，带有两个参数并返回值的简单方法

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class Service : IService
{
    public string GetAddNumbers(int a, int b)
    {
        return (a + b).ToString();
    }
}

服务网站配置

  <system.web>
    <compilation targetFramework="4.5" />
    <httpRuntime targetFramework="4.5"/>

Answer 1

跨域代理有3个设置：＆＃34;远程＆＃34;，＆＃34;本地＆＃34;和＆＃34;禁用＆＃34;。

我设置＆＃34;禁用＆＃34;工作很好。

感谢所有

Answer 2

我在远程计算机上遇到了与WCF服务相同的问题。我将跨域代理设置从“本地”更改为“远程”和“禁用”，即使我为每个请求添加了Access-Control-Allow-Origin标头，它也不起作用。

我注意到代理端口与Chrome地址栏中的端口不同; 一个是4400，另一个是 http://localhost:4443/index.html?enableripple=cordova-3.0.0-NexusGalaxy

当我更改代理端口以匹配地址栏中的端口时，调用成功。

如果它们不匹配则错误是：无法加载资源：net :: ERR_CONNECTION_REFUSED文件：xhr_proxy，行：0，列：0
