篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Retrofit2.0得到MalformedJsonException,而json似乎正确吗?相关的知识,希望对你有一定的参考价值。
我正在使用改装:2.0.0-beta4为我的android应用程序。
我尝试添加用户使用Retrofit,用户在数据库中正确创建,但是我收到以下错误:
03-14 06:04:27.731 30572-30600/com.lehuo.lehuoandroid D/OkHttp: CALLING POST SP_User_CreateUser....your new user_id:48

服务器返回的结果是:
{"data":{"user_id":"48","nickname":null,"password":null,"status":null},"status":1,"msg":"OK"}
这是正确的json格式,我不明白为什么我得到这样的异常?
我们这里是我的界面:
public class ApiResult<T> {
public T data;
public int status;
public String msg;
}
public interface ApiUsers {
@POST("/users/new")
public Call<ApiResult<User>> createUser(@Body User user);
}
public class User {
public int user_id;
public String registration;
public int registration_type;
public String avatar;
public String nickname;
public String password;
public String status;
}
public class Api {
// TODO modify the value
public static final String BASE_URL = "xxx";
private static Api instance = new Api();
public static Api getInstance() {
return instance;
}
private Api(){}
public Retrofit getRetrofit() {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(interceptor)
.retryOnConnectionFailure(true)
.connectTimeout(15, TimeUnit.SECONDS)
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build();
return retrofit;
}
public <S> S createService(Class<S> serviceClass) {
return getRetrofit().create(serviceClass);
}
}
来电者代码是:
ApiUsers api = Api.getInstance().createService(ApiUsers.class);
Call<ApiResult<User>> call = api.createUser(user);
CreateUserMessage message = new CreateUserMessage();
callNet(call, message);
任何人都可以提供任何线索吗?
答案
最后我解决了我的问题,这个问题与json lenient模式无关,我的POST响应有问题(在json数据之前有一些其他非json输出)。
以下是JakeWharton关于如何设置Gson宽松模式的回复:
make sure that you have:
compile 'com.google.code.gson:gson:2.6.1'
Gson gson = new GsonBuilder()
.setLenient()
.create();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
另一答案
我解决了这个问题
Gson gson = new GsonBuilder().setLenient().create();
OkHttpClient client = new OkHttpClient();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://kafe.netai.net/")
.client(client)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.google.code.gson:gson:2.7'
