com.google.gson.JsonIOException：JSON文档未在Android Retrofit中完全使用

时间：2019-01-18 15:26:11

标签： java android json retrofit2 slim

对于Stackoverflow中的“ JSON文档未完全使用”，已经有几个问题，但是没有公认的答案。链接如下。

Android Retrofit 2.0 JSON document was not fully consumed

Why is JSON document not fully consumed?

在我的应用中，我正在接收用户的电子邮件。然后使用我的API，检查数据库中是否存在给定的电子邮件。如果存在，我正在向该电子邮件发送代码。我使用本地主机作为服务器，并且使用了Slim for API。我认为我的API可以。我通过邮递员检查了它。我在帖子中分享的Json回复来自Postman。实际上，我正在学习改造。请帮助。预先感谢。

RetrofitClient.java 

package com.example.royta.retrofitdemo.APIs;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

public class RetrofitClient {
    private static final String BASE_URL = "http://aa561878.ngrok.io/MyApi/public/";
    private static RetrofitClient retrofitClient;
    private Retrofit retrofit;

    private static Gson gson = new GsonBuilder()
            .setLenient()
            .create();

    private RetrofitClient() {

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

    public static synchronized RetrofitClient getInstance() {
        if(retrofitClient == null) {
            retrofitClient = new RetrofitClient();
        }
        return retrofitClient;
    }

    public Api getApi() {
        return retrofit.create(Api.class);
    }
}

Json 

{
    "isSend": true,
    "code": 117482,
    "email": true
}

UserExist.java（Pojo） 

package com.example.royta.retrofitdemo.ModelClass;

import com.google.gson.annotations.SerializedName;
public class UserExist {
    @SerializedName("email")
    private boolean email;
    @SerializedName("isSend")
    private boolean isSend;
    @SerializedName("code")
    private int code;

    public UserExist(boolean email, boolean isSend, int code) {
        this.email = email;
        this.isSend = isSend;
        this.code = code;
    }

    public boolean isSend() {
        return isSend;
    }

    public boolean isEmailExist() {
        return email;
    }

    public int getCode() {
        return code;
    }
}

Api.java 

package com.example.royta.retrofitdemo.APIs;

import com.example.royta.retrofitdemo.ModelClass.UserExist;
import retrofit2.Call;
import retrofit2.http.GET;

public interface Api {

    @GET("finduser")
    Call<UserExist> isUserExist(
            @Query("email") String email

    );
}

这是电话

        Call <UserExist> call = RetrofitClient.getInstance().getApi().isUserExist(email);    
        call.enqueue(new Callback<UserExist>() {
            @Override
            public void onResponse(Call<UserExist> call, Response<UserExist> response) {
                if(response.body().isEmailExist()) {

                    String resetCode = String.valueOf(response.body().getCode());
                    Log.d("ROYs", "Reset Code: "+resetCode);
                    Intent i = new Intent(FindAccount.this, EnterSecurityCode.class);
                    i.putExtra("email", email);
                    i.putExtra("code", resetCode);
                    startActivity(i);
                }
                else {

                    Toast.makeText(FindAccount.this, "You are not registered", Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void onFailure(Call<UserExist> call, Throwable t) {
                String stacktrace = Log.getStackTraceString(t);
                Log.d("ROYs", "onFailure Method: "+stacktrace);
            }
        });

当我收到此错误消息“ JSON文档未完全使用”时，我遇到的问题仅仅是在JSON字符串的末尾有多余的文本。

在我的情况下，我手动将文本添加到有效JSON字符串的末尾，以在星期五和星期一之前“测试”错误处理并重试逻辑，而忘记了我添加了此临时代码！

您应该按照与json中相同的顺序将字段放入模型类中

@SerializedName("isSend")
private boolean isSend;
@SerializedName("code")
private int code;
@SerializedName("email")
private boolean email;
