別の Web サービス (AndroidService) から呼び出している Web サービス (LoginService) があります。接続をテストする簡単な方法がありますが、機能していません。

LoginService には getStuff(string password) というメソッドがあります。JSON で文字列を返します。ブラウザから直接アクセスすると、http://localhost/LoginService/LoginService.svc/getStuff/fooで正常に動作します。他の Web サービスを介して同じことを試みると、件名の例外と InnerException "The server returned 404 Not Found" で失敗します。

LoginService の定義は次のとおりです。

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

AndroidService のコードは次のとおりです。

    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);
    }

そして AndroidService 定義:

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

完全な例外は次のとおりです。

Request Error
The server encountered an error processing the request. The exception message is 'There was no endpoint listening at http://localhost/LoginService/LoginService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.'. See server logs for more details. The exception stack trace is:

Fiddler リクエストを取得するためにサーバーを削除するように LoginService を移動しました。

あなたと同様のシナリオで示されています：

ログインサービス:

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

Android サービス:

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

今、私の LoginService 実装:

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

今私の AndroidService 実装:

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: LoginService は別の RESTful サービスとしてホストされているため、WebRequestClass を使用してアクセスすると想定しています。LoginService が同じプロジェクトにある場合は、AndroidService と同様の LoginService のサービス要素を定義します。これで十分です。
