Question

在将json对象发送到服务器时，我遇到上述异常，这是我完整的代码。

RegisterModelQ.java

public class RegisterModelQ {
    @SerializedName("name")
    private String name;
    @SerializedName("mobile")
    private String mobile;
    @SerializedName("password")
    private String password;
    @SerializedName("device_token")
    private String deviceToken;
    @SerializedName("device_type")
    private String deviceType;

    public RegisterModelQ(String name, String mobile, String password, String device_type, String device_token) {
        this.name = name;
        this.mobile = mobile;
        this.password = password;
        this.deviceToken= device_token;
        this.deviceType = device_type;

    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

ApiInterface.java

@FormUrlEncoded
@POST("user/log-in")
Call<LoginModelR> getLoginAPI(LoginModelQ loginModel);

APIClient.java

public static Retrofit getRetrofit() {
    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor)
            .build();

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


    return retrofit;

我的电话

@Override
public void registerCall(RegisterModelQ registerModelQ) {
    view.showProgress();
    APIInterface apiService = APIClient.getRetrofit().create(APIInterface.class);
    JSONObject jsonObject = null;
    String string = Utils.getGson().toJson(registerModelQ);
    try {
         jsonObject = new JSONObject(string);
    } catch (JSONException e) {
        e.printStackTrace();
    }
    Call<RegisterModelR> call = apiService.getRegisterAPI(jsonObject);
    call.enqueue(new Callback<RegisterModelR>() {
        @Override
        public void onResponse(Call<RegisterModelR> call, Response<RegisterModelR> response) {
            view.hideProgress();
            if (response.isSuccessful()) {
                view.changeView(new DashboardFragment());
            }

        }

        @Override
        public void onFailure(Call<RegisterModelR> call, Throwable t) {
            Utils.logD(TAG, "Errrr: " + t.getMessage());
            view.hideProgress();
        }
    });

}

我发现了许多与我有关的问题，但没有解决我的错误，加上如果我想将Java对象发送到API怎么办。我应该在服务器端用PHP来实现吗？

请遵循以下步骤。

步骤1：

    public JSONObject getJsonObject(Object object) {
        ObjectMapper mapperObj = new ObjectMapper();
        JSONObject jsonObject = null;

        try {
            String jsonStr = mapperObj.writeValueAsString(object);
            try {
                jsonObject = new JSONObject(jsonStr);
                return jsonObject;
            } catch (JSONException e) {
                e.printStackTrace();
            }
        } catch (JsonProcessingException e) {
            e.printStackTrace();
            return null;
        }

        return jsonObject;
    }

步骤2：

    APIInterface apiService = APIClient.getRetrofit().create(APIInterface.class);
        Call<RegisterModelR> call = apiService.getLoginAPI(RequestBody.create(MediaType.parse("application/json"),
                getJsonObject(registerModelQ).toString()));

步骤3：

    @POST("user/log-in")
    Call<LoginModelR> getLoginAPI(@Body RequestBody requestBody);

祝你好运。
