Stackoverflow 中已经有几个关于“JSON 文档未完全使用”的问题，但没有公认的答案。链接如下。
Android Retrofit 2.0 JSON document was not fully consumed
Why is JSON document not fully consumed?
在我的应用程序中，我正在接收用户的电子邮件。使用我的 API，我检查数据库中是否存在给定的电子邮件。如果存在，我将向该电子邮件发送代码。我使用 localhost 作为服务器，并使用 Slim 作为 API。我认为我的 API 没问题。我通过 postman 检查过。我在帖子中分享的 Json 响应来自 Postman。其实我正在学习Retrofit。请帮助。提前致谢。
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
);
}
电话来了👇
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);
}
});

最佳答案
当我收到此错误消息“JSON 文档未完全使用”时遇到的问题只是 JSON 字符串末尾有无关的文本。
就我而言，我手动将文本添加到有效 JSON 字符串的末尾，以在周五“测试”错误处理和重试逻辑，然后周一忘记了我添加了此临时代码!
关于java - com.google.gson.JsonIOException : JSON document was not fully consumed in Android Retrofit，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54256940/
