改造call.enqueue代碼200，但response.body（）為空

Question

我從API的 response.body()獲取JSON時遇到問題。

Logcat顯示請求成功，但是當我要將主體復制到模型對象時，它為null。

我已經只將JSON縮短為一個鍵和一個值（logcat的結尾），但是即使這樣我也無法讀取響應。

Logcat：

D/OkHttp: <-- 200  http://10.0.2.2:8080/groups?page=1&limit=25 (33ms)    
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Pragma: no-cache
Expires: 0
X-Frame-Options: DENY
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Mon, 14 Jan 2019 19:31:10 GMT
D/OkHttp: [{"name":"Delfiny"}]
<-- END HTTP (20-byte body)

型號類別：

public class GroupsResponseModel {

@SerializedName("name")
@Expose
private String name;

public GroupsResponseModel() {
}

public GroupsResponseModel(String name) {
    this.name = name;
}

public String getName() {
    return name;
}

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

Api接口：

@GET("groups")
Call<GroupsResponseModel> getGroups(@Query("page") int page, 
@Query("limit") int limit);

改造和攔截器：

public static Retrofit getClient()
{
    HttpLoggingInterceptor interceptor = new 
HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

    OkHttpClient okHttpClient = new OkHttpClient().newBuilder().
            addInterceptor(new Interceptor() {
        @Override
        public okhttp3.Response intercept(Chain chain) throws 
IOException {
            Request originalRequest = chain.request();

            Request.Builder builder = originalRequest.newBuilder().header(Utils.getAuthKey(),
                    Utils.getAuthValue());

            Request newRequest = builder.build();
            return chain.proceed(newRequest);
        }
    })
            .addInterceptor(interceptor)
            .build();

    retrofit = new Retrofit.Builder()
            .baseUrl(Utils.getURL())
            .client(okHttpClient)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    return retrofit;
}

呼叫入隊：

Call<GroupsResponseModel> call = apiInterface.getGroups(1, 25);

            call.enqueue(new Callback<GroupsResponseModel>() {
                @Override
                public void onResponse(Call<GroupsResponseModel> call, Response<GroupsResponseModel> response) {

                     groupsResponseModel = response.body();

                    Toast.makeText(GroupActivity.this, "response: " + groupsResponseModel.getName(), Toast.LENGTH_LONG).show();
                    //groups = new ArrayList<>(Arrays.asList(groupsResponseModel.getName()));
                    groupAdapter = new GroupAdapter(groups);
                    recyclerView.setAdapter(groupAdapter);

                }

                @Override
                public void onFailure(Call<GroupsResponseModel> call, Throwable t) {

                }
            });

預期結果需要解析。

如果您完全確定服務器會發送正確的json，請檢查您的pojo類。 首先刪除@Exposed注解

Answer 2

我建議您使用Profiler之類的Android Studio調試工具監視可在Profiler的“網絡”部分輕松訪問的網絡（API調用）請求和響應主體，請查看以下鏈接： Android Profiler
