java - Android Rest Api Post 400 错误请求

Question

我正在开发一个应用程序，它将向服务器发送密码以检查其是否正确，服务器将返回代表不同状态的0,1,2,3我不确定这个 400 错误请求是从哪里来的。我已经调用服务器并收到了 json 文件，但我怀疑这就是我解析它的方式？非常感谢任何帮助。

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”，它代表发生了错误。我已将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，它代表密码不正确。然而我的错误请求400仍然存在。请任何帮助或建议对我非常有帮助

@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;
    }
}

调用服务器:

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;
}

创建请求适配器

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

我已经弄清楚了。我正在处理错误的异常，并且 API 返回 400 而不是 401，因为发送了错误的密码。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。
