C# Webservice返回EndPointNotFoundException

我从另一个web服务（AndroidService）调用了一个web服务（LoginService）。我有一个测试连接的简单方法，但它不起作用

在LoginService中，我有一个名为getStuff（字符串密码）的方法—它返回JSON格式的字符串。当我通过浏览器直接访问它时，它可以正常工作。当我通过另一个web服务尝试相同的操作时，它失败了，主题中出现异常，内部异常为“服务器返回404 Not Found”

以下是LoginService定义：

        [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "getStuff/{password}")]
        string getStuff(string password);

    [OperationContract]
    [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "getStuff/{password}")]
    string getStuff(string password);

以下是AndroidService的代码：

    public string getStuff(string password)
    {
        string endpoint_address = "http://localhost/LoginService/LoginService.svc/";

        BasicHttpBinding binding = new BasicHttpBinding();
        EndpointAddress address = new EndpointAddress(endpoint_address);

        client = new LoginServiceClient(binding, address);
        return client.getStuff(password);
    }

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json,UriTemplate = "getStuff/{password}")]
string getStuff(string password);

以及AndroidService定义：

        [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "getStuff/{password}")]
        string getStuff(string password);

    [OperationContract]
    [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "getStuff/{password}")]
    string getStuff(string password);

以下是完全例外：

显示了与您类似的场景：

登录服务：

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json,UriTemplate = "getStuff/{password}")]
string getStuff(string password);

AndroidService：

    public string getStuff(string password)
    {
        string endpoint_address = "http://localhost/LoginService/LoginService.svc/";

        BasicHttpBinding binding = new BasicHttpBinding();
        EndpointAddress address = new EndpointAddress(endpoint_address);

        client = new LoginServiceClient(binding, address);
        return client.getStuff(password);
    }

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json,UriTemplate = "getStuff/{password}")]
string getStuff(string password);

现在，我的登录服务实现：

public string getStuff(string password)
{
    if ( password == "test")
          return "Success";
    else
          return "Failure";
}

public string getStuff(string password)
{
    // NOTE: Below 2 lines to acccess the login service via SOAP 
    // assuming that you have added a service reference to your project and added the needed config entries in you androidservice config file
    LoginServiceClient client = new LoginServiceClient(binding, address);
    return client.getStuff(password);

     // NOTE: Below code to access it RESTfully 
     string responseMessage = null;
     var request = WebRequest.Create("http://localhost/LoginService/LoginService.svc/getStuff/" + password) as HttpWebRequest;
    if (request != null)
    {
        request.ContentType = "application/json";      
        request.Method = "GET";
        var response = request.GetResponse() as HttpWebResponse;
                if(response.StatusCode == HttpStatusCode.OK)
                {
                    Stream responseStream = response.GetResponseStream();
                    if (responseStream != null)
                    {
                        var reader = new StreamReader(responseStream);

                        responseMessage = reader.ReadToEnd();                        
                    }
                }
                else
                {
                    responseMessage = response.StatusDescription;
                }
    }
    if (responseMessage == "Success")
    {
        return "Success";
    }
    else
    {
        return "Failure";
    }
}

现在，我的AndroidService实现：

public string getStuff(string password)
{
    if ( password == "test")
          return "Success";
    else
          return "Failure";
}

public string getStuff(string password)
{
    // NOTE: Below 2 lines to acccess the login service via SOAP 
    // assuming that you have added a service reference to your project and added the needed config entries in you androidservice config file
    LoginServiceClient client = new LoginServiceClient(binding, address);
    return client.getStuff(password);

     // NOTE: Below code to access it RESTfully 
     string responseMessage = null;
     var request = WebRequest.Create("http://localhost/LoginService/LoginService.svc/getStuff/" + password) as HttpWebRequest;
    if (request != null)
    {
        request.ContentType = "application/json";      
        request.Method = "GET";
        var response = request.GetResponse() as HttpWebResponse;
                if(response.StatusCode == HttpStatusCode.OK)
                {
                    Stream responseStream = response.GetResponseStream();
                    if (responseStream != null)
                    {
                        var reader = new StreamReader(responseStream);

                        responseMessage = reader.ReadToEnd();                        
                    }
                }
                else
                {
                    responseMessage = response.StatusDescription;
                }
    }
    if (responseMessage == "Success")
    {
        return "Success";
    }
    else
    {
        return "Failure";
    }
}

注意：我假设您的LoginService作为一个独立的RESTful服务托管，因此使用WebRequestClass访问它。如果LoginService在同一个项目中，那么为LoginService定义一个类似于AndroidService的服务元素就足够了。

我想您需要使用WebHttpBinding而不是BasicHttpBinding，因为您的服务似乎是REST，andriod使用REST而不是SOAP访问它。将其更改为WebHttpBinding，现在我得到了InvalidOperationException，表示“此工厂已启用手动寻址，因此发送的所有邮件都必须预寻址。”=（您是否尝试从Fiddler访问服务，并查看得到的响应。另外，请发布您的服务配置文件posted web.config，将代码更改为client=new LoginServiceClient（）；而不是客户端=新的LoginServiceClient（绑定，地址）；你能发布fiddler的原始请求吗？如果我没有错的话，我看到你从andriodservice调用loginservice。对吗？是的，我可以通过手动发出http请求来让它工作，但这会使整个实现有点模糊，必须为每个实现定义请求的url。--我想这样做LoginServiceClient=new LoginServiceClient（）；然后通过client.getStuff（“string”）使用这些方法；使用LoginServiceClient=new LoginServiceClient（）的过程；指使用基于SOAP的web服务，也可以通过在AndroidService中添加LoginService的服务引用，并使用上述代码，而不是使用WebRequest类对其执行调用来实现。我已将LoginService的服务引用添加到AndroidService。当我键入LoginServiceClient=new LoginServi时ceClient（）；然后是客户端。它建议使用getStuff方法，因此我知道它可以看到公开的web服务。它不起作用，我完全不知道如何让它工作。您可以发布LoginService的服务器配置吗？也可以在androidService上查看我更新的web.config，其中有一个客户端元素引用LoginService端点及其应用程序关联的BasicHttpBinding元素（假设登录服务在没有任何安全性的情况下使用BasicHttpBinding公开）将您的答案标记为正确，因为它会有效地给出使用loginservice作为rest的正确结果。我启动了一个新项目，复制粘贴了其中的所有内容，现在它可以工作了。：S
