没有从 Retrofit 获得任何数据。它向服务器发送空请求

Question

我对 Retrofit 调用有疑问。我曾调用在服务器上发布数据，调用返回 200 响应，这意味着调用成功，但它没有将任何数据保存到数据库并在服务器堆栈跟踪中返回消息“请求为空”。没有得到响应数据。

接口调用

  @Headers({"org-id: vuk"})
 @POST("/dmp/user/loginwithotp")
    Call<ResponseAPI> signInWithOTP(@Body RequestBody jsonObject);

改造电话

    OkHttpClient client = new OkHttpClient.Builder()
    .connectionSpecs(Arrays.asList(ConnectionSpec.MODERN_TLS, ConnectionSpec.CLEARTEXT))
            .addInterceptor(loggingInterceptor)
            .addNetworkInterceptor(new CacheInterceptor(mContext))
            .connectTimeout(30, TimeUnit.SECONDS)
            .writeTimeout(30, TimeUnit.SECONDS)
            .readTimeout(30, TimeUnit.SECONDS)
            .build();

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(baseUrl )
            .addConverterFactory(GsonConverterFactory.create(new Gson()))
 
            .client(client)
            .build();
    return retrofit;
}
public static VuAPIServices geVuAPIServices() {
    VuAPIServices vuAPIServices = getRetrofit().create(VuAPIServices.class);
    return vuAPIServices;
}

活动中发送调用请求和响应调用的代码

    try {
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("mobileNumber", mobileNumber);
        RequestBody body = RequestBody.create(json.toString(), MediaType.parse("application/json;charset=UTF-8"));


        Call<ResponseAPI> responseAPICall = ApiClient.geVuAPIServices().signInWithOTP(body);
        responseAPICall.enqueue(new Callback<ResponseAPI>() {
            @Override
            public void onResponse(Call<ResponseAPI> call, retrofit2.Response<ResponseAPI> response) {
                    if(!response.isSuccessful()) {
                        Log.e("TAG", "response: "+new Gson().toJson(response.body()) );
                        }
                    }

                @Override
            public void onFailure(Call<ResponseAPI> call, Throwable t) {
                    Log.e("TAG", "onFailure: "+t.toString() );
            }
        });
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

响应 POJO

    @SerializedName("flag")
    private int flag;

    @SerializedName("message")
    private String message;
    @SerializedName("status")
    private Boolean status;
    @SerializedName("otp")
    private String otp;
    @SerializedName("locked")
    private Boolean locked;
    @SerializedName("firstTimeLogin")
    private Boolean firstTimeLogin;
    @SerializedName("firstLogin")
    private Boolean firstLogin;

Getter and Setters...

我应该对我的代码进行哪些更改？我欢迎每一个提示。我得到的状态是 200 但服务器端的请求为空。

已更新响应结果

E/TAG: response: {"firstLogin":false,"firstTimeLogin":false,"flag":0,"fromInternalApp":false,"locked":false,"mobileNumber":"4455332266","noToken":false,"status":false}

我已经解决了我的问题，这是我需要在 okhttp 拦截器的标头中发送主机的问题

httpClient.addInterceptor(new Interceptor() {
    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request original = chain.request();

        Request request = original.newBuilder()
                 .addHeader("Content-Type", "application/json")
                .addHeader("User-Agent", System.getProperty("http.agent"))
                .addHeader("Host", "localhost:8080")
                .method(original.method(), original.body())
                .build();

        return chain.proceed(request);
    }
});

我在拦截器中添加这个后不久，问题就解决了，它得到了成功返回的响应。

E/TAG: response: {"firstLogin":false,"firstTimeLogin":false,"flag":1,"fromInternalApp":false,"locked":false,"message":"true OTP sent successfully on mobile number for Initial Login","noToken":false,"otp":"573287","status":false}

这可能是因为您正在发送一个 json 对象。您可以尝试创建一个请求对象并将其发送：

public class RequestObject {

private String mobileNumber;

public RequestObject(String mobileNumber) {
    this.mobileNumber = mobileNumber;
}

public String getMobileNumber() {
    return mobileNumber;
}

public setMobileNumber(String mobileNumber) {
    this.mobileNumber = mobileNumber;
}
}

然后在请求中发送：

 @Headers({"org-id: vuk"})
 @POST("/dmp/user/loginwithotp")
 Call<ResponseAPI> signInWithOTP(@Body RequestObject requestObject); // here
