Android Rest Api Post 400错误请求

Question

我正在开发一个应用程序，该应用程序将向服务器发送密码以检查密码是否正确，服务器将返回0、1、2、3，分别代表不同的状态，我不确定这400个错误请求来自何处。 我已经呼叫服务器并收到json文件，但我怀疑它是我解析的方式？ 任何帮助是极大的赞赏。

更新

更新。 我意识到这里的部分错误是我试图发送一个字符串而不先将其转换为JSON文件。 这就是为什么我一直收到“ status：0”表示发生错误的原因。 我已经将我的字符串转换为包含字符串变量的RegisterRequest对象。 现在，我收到状态2，表示密码错误。 但是我的错误请求400仍然存在。 请任何帮助或建议对我都会非常有帮助

@Headers("Content-Type: application/json")
@POST("removed/{id}")
RegisterResponse registerEvent(
    @Path("id") int ID, 
    @Body RegisterRequest password
) throws NetworkException;

RegisterResponse类：

public class RegisterResponse {
    public String status;
}

RegisterRequest类

public class RegisterRequest {

    String passcode ;

    public RegisterRequest(String passcode)
    {
        this.passcode=passcode;
    }
}

呼叫伺服器：

try {
    RegisterResponse response = NetworkHelper.makeRequestAdapter(this)
               .create(testApi.class).register(ID, pass);

        if(response.status=="1"||response.status=="3")
        {
            return true;
        }
        else
            return false;
    } catch (NetworkException e) {
        e.printStackTrace();
    }
   return false;
}

发出请求适配器

private static RestAdapter.Builder makeRequestAdapterBuilder(final Context context, ErrorHandler errorHandler, String dateTimeFormat)
    {
        RequestInterceptor requestInterceptor = new RequestInterceptor()
        {
            @Override
            public void intercept(RequestInterceptor.RequestFacade request)
            {
                request.addHeader("Authorization", AppPrefs.getInstance(context).getSessionToken());
            }
        };

        Gson gson = new GsonBuilder().setDateFormat(dateTimeFormat).create();
        GsonConverter gsonConverter = new GsonConverter(gson);

        RestAdapter.Builder builder = new RestAdapter.Builder()
                .setRequestInterceptor(requestInterceptor).setConverter(gsonConverter)
                .setLogLevel(RestAdapter.LogLevel.FULL).setLog(new AndroidLog("Boom!"))
                .setEndpoint(BASE_URL);

        if(errorHandler != null)
        {
            builder.setErrorHandler(errorHandler);
        }

        if(instance == null)
        {
            instance = new OkClient(makeTimeoutClient(READ_TIMEOUT, CONNECT_TIMEOUT));
        }
        builder.setClient(instance);

        return builder;
    }

Answer 1

我知道了。 我正在处理错误的异常，并且API发送错误的密码返回400（而不是401）。 我已将对服务器网络异常错误的调用更改为异常错误。

感谢大家的帮助。

Answer 2

你有

 @Headers("Content-Type: application/json")
 @POST("removed/{id}")
 RegisterResponse registerEvent(@Path("eventID") int eventID, @Body RegisterRequest password)throws NetworkException;

请注意，您将id称为参数（在@POST批注中），然后在参数中使用@Path("eventID") 。

尝试将代码更改为

 @Headers("Content-Type: application/json")
 @POST("removed/{eventID}")
 RegisterResponse registerEvent(@Path("eventID") int eventID, @Body RegisterRequest password)throws NetworkException;
