【问题描述】：

我有包含此方法的 WCF 服务：

[OperationContract]
    [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "GetListInvititionFiltered?StartPage=StartPage&userID=userID&subject=subject&customerName=customerName&country=country&invitationType=invitationType&productGroup=productGroup&companyGroup=companyGroup&marketingEngineer=marketingEngineer&proposalEngineer=proposalEngineer&fromDate=fromDate&toDate=toDate&closingDate=closingDate&sDataSourse=sDataSourse&sCatalog=sCatalog")]
    string GetListInvititionFiltered(string StartPage, string userID, string subject, string customerName, string country, string invitationType,
        string productGroup, string companyGroup, string marketingEngineer, string proposalEngineer, string fromDate, string toDate, string closingDate, string sDataSourse, string sCatalog);

当我从浏览器调用这个方法时：

localhost:8080/androidWCFRestfull/AAPRestFullHttp.svc/GetListInvititionFiltered?StartPage=3&userID=104&subject=&customerName=&country=&invitationType=&productGroup=&companyGroup=&marketingEngineer=&proposalEngineer=&fromDate=01%2f02%2f2017&toDate=01%2f02%2f2017&closingDate=&sDataSourse=DB01-SRV&sCatalog=AAP

它在浏览器中返回这个 JSON：

我正在尝试使用 Retrofit 从 Android 应用程序读取此 JSON，这是服务方法的接口：

public interface AAPRestfulEndPointInterface 

@POST("GetListInvititionFiltered")
Call<InvitationsContainer> GetListInvititionFiltered(@Query("StartPage") String StartPage,
                                                     @Query("userID") String userID,
                                                     @Query("subject") String subject,
                                                     @Query("customerName") String customerName,
                                                     @Query("country") String country,
                                                     @Query("invitationType") String invitationType,
                                                     @Query("productGroup") String productGroup,
                                                     @Query("companyGroup") String companyGroup,
                                                     @Query("marketingEngineer") String marketingEngineer,
                                                     @Query("proposalEngineer") String proposalEngineer,
                                                     @Query("fromDate") String fromDate,
                                                     @Query("toDate") String toDate,
                                                     @Query("closingDate") String closingDate,
                                                     @Query("sDataSourse") String sDataSourse,
                                                     @Query("sCatalog") String sCatalog);

这是服务的代码调用：

Gson gson = new GsonBuilder()
            .setDateFormat("MM-dd-yyyy")
            .create();

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .build();

    AAPRestfulEndPointInterface service = retrofit.create(AAPRestfulEndPointInterface.class);


    final Call<InvitationsContainer> apiCall = service.GetListInvititionFiltered("1", "104", "", "", "", "", "", "", "", "", "01/01/2017","01/02/2017", "", "DB01-SRV", "AAP");

    String url = apiCall.request().url().toString();
    Log.i("RETROFIT", url);

    apiCall.enqueue(new Callback<InvitationsContainer>() 
        @Override
        public void onResponse(Call<InvitationsContainer> call, Response<InvitationsContainer> response) 

            Log.i("RETROFIT", "onResponse Called");
            InvitationsContainer result = response.body();

        

        @Override
        public void onFailure(Call<InvitationsContainer> call, Throwable t) 

            Toast.makeText(MainActivity.this, "Service Call Failure \n" + t.getMessage(), Toast.LENGTH_LONG).show();
            Log.e("RETROFIT", t.getMessage());

        
    );

响应对象返回空正文和错误代码 405 的问题，谁能帮我解决这个问题？

这是原始响应：

响应protocol=http/1.1, code=405, message=Method Not Allowed, url=http://xx.xx.xx.xx:8181/AndroidWCFRestfull/AAPRestFullHttp.svc/GetListInvititionFiltered?StartPage=1&userID=104&subject=&customerName=&country=&invitationType=&productGroup=&companyGroup=&marketingEngineer=&proposalEngineer=&fromDate=01/01/2017&toDate=01/02/2017&closingDate=&sDataSourse=DB01-SRV&sCatalog=AAP

【问题讨论】：

@POST("/GetListInvititionFiltered") 在您的 intarface 中使用反斜杠。

我会检查它，但我将反斜杠放在 baseURL @Sorathiya Payal

【参考方案1】：

您的 WCF 服务仅接受 GET 请求。但是AAPRestfulEndPointInterface 中的GetListInvititionFiltered 方法被声明为POST。

@POST("GetListInvititionFiltered")
Call<InvitationsContainer> GetListInvititionFiltered(..);

将其更改为GET 以消除Method Not Allowed 错误。

@GET("GetListInvititionFiltered")
Call<InvitationsContainer> GetListInvititionFiltered(..);
