我正在使用改造从 Flickr api 获取一些数据。我正在调用的方法如下所示:
public static List<String> getImageIds(int size) {
Call<PhotosList> call = flickrService.getPhotos(apiKey, format, "1");
Log.d("TEMP_TAG", "photo url: " + call.request().url().toString());
photoIds = new ArrayList<String>();
call.enqueue(new Callback<PhotosList>(){
@Override
public void onResponse(Call<PhotosList> call, Response<PhotosList> response) {
Log.d("TEMP_TAG", "it's getting here");
PhotosList photosList = response.body();
List<Photo> photos = photosList.getPhotos().getPhoto();
for(Photo photo : photos) {
Log.d("TEMP_TAG", "adding photo id to list: " + photo.getId());
photoIds.add(photo.getId());
}
}
@Override
public void onFailure(Call<PhotosList> call, Throwable t) {
// TODO: Clean up
Log.d("TEMP_TAG", "photoId: ");
}
});
Log.d("TEMP_TAG", "it's getting here too");
return photoIds;
}
但是它永远不会进入 onResponse()
方法。 onResponse()
中的第一条日志语句从不打印,onFailure()
中的日志语句也不会打印。当我尝试在浏览器中输入 call.request().url().toString()
返回的 URL 时,它工作正常,我得到了预期的 JSON。为什么我的 enqueue()
方法永远不会触发?
感谢您的帮助!
最佳答案
使用 HttpLoggingInterceptor与改造一起。
如果这有帮助,请将其添加到您的 build.gradle 中 -
//Retrofit and OkHttp for Networking
implementation 'com.squareup.retrofit2:retrofit:2.9.0'
implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
//Logging Network Calls
implementation 'com.squareup.okhttp3:logging-interceptor:4.9.1'
在你的 APIClient 类
中添加这个 -
public class ApiClient {
private static Retrofit retrofit = null;
public static Retrofit getClient(){
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(interceptor)
.build();
if(retrofit==null){
retrofit = new Retrofit.Builder()
.baseUrl(BuildConfig.baseUrl)
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
}
return retrofit;
}
}
Kotlin 代码
val interceptor : HttpLoggingInterceptor = HttpLoggingInterceptor().apply {
level = HttpLoggingInterceptor.Level.BODY
}
val client : OkHttpClient = OkHttpClient.Builder().apply {
addInterceptor(interceptor)
}.build()
fun getService(): Service {
return Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(LiveDataCallAdapterFactory())
.client(client)
.build()
.create(Service::class.java)
}
您将能够记录您进行的改造网络调用。
