Question

当我将response.body（）转换为POJO类时，如何关闭response.body？

public class RetrofitClient {
   private static Retrofit retrofit = null;
   private final static OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .readTimeout(10, TimeUnit.SECONDS)
        .writeTimeout(10, TimeUnit.SECONDS)
        .connectTimeout(10, TimeUnit.SECONDS)
        .build();

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

   public static Retrofit getClient(String baseUrl) {
     if (retrofit == null){
         retrofit = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .client(okHttpClient)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();
     }
     return retrofit;
   }}

public static class GroupMembersCallback implements Callback<GroupAdminPreview>{
    private List<String> usersUsername = new ArrayList<>();
    private List<String> usersFullName = new ArrayList<>();
    private List<String> usersIsAdmin = new ArrayList<>();
    private GroupMembersAdapter membersAdapter;
    private WeakReference<RecyclerView> mRecyclerView;
    private WeakReference<Context> contextWeakReference;

    public GroupMembersCallback(WeakReference<RecyclerView> mRecyclerView, WeakReference<Context> context){
        this.mRecyclerView = mRecyclerView;
        contextWeakReference = context;
    }

    @Override
    public void onResponse(Call<GroupAdminPreview> call, Response<GroupAdminPreview> response) {
        GroupAdminPreview groupAdminPreview = response.body();

        for (GroupAdminPreview.GroupUser groupUser : groupAdminPreview.getGroupUsers()){
            usersUsername.add(groupUser.getUserName());
            usersFullName.add(groupUser.getFirstName() + " " + groupUser.getLastName());
            usersIsAdmin.add(groupUser.getIsAdmin());
        }
        membersAdapter = new GroupMembersAdapter(usersUsername, usersFullName, usersIsAdmin, contextWeakReference, mRecyclerView);
        mRecyclerView.get().setAdapter(membersAdapter);
    }
    @Override
    public void onFailure(Call<GroupAdminPreview> call, Throwable t) {
        System.out.println(t);
    }
}

我在阅读关于使用此代码后关闭response.body的内容：

ResponseBody body = response.body();
body.close();

但是当我使用POJO课程时，我无法做同样的事情。对不起，我还是开发Android应用程序的初学者。

我的应用程序运行一段时间后，我在Android Monitor中得到了这个：

A connection to ....... was leaked. Did you forget to close a response body?

Answer 1

事实上，如果使用Retrofit，您不需要关闭ResponseBody。转换器为你做了。

e.g。如果您使用JacksonConverterFactory，则会有名为JacksonResponseBodyConverter的类，请参阅下面的代码：

@Override public T convert(ResponseBody value) throws IOException {
    try {
      return adapter.readValue(value.charStream());
    } finally {
    value.close();
    }
}

编辑：尝试检查onResponse回调中的响应是否成功，如果响应不成功则调用response.errorBody.close（）

Answer 2

Okhttp和Retrofit使用冲突。或者查看这些库的旧版本。

Retrofit 2为您关闭ResponseBody

使用POJO类
