我正在尝试查询FlickR照片并接收JSON响应。我正在使用Retrofit来调用FlickR API。在我的代码中,用户输入文本,该文本通过EditText捕获。我想根据这个词查询。我从Flick收到以下错误:“无参数搜索已被禁用。请改用flickr.photos.getRecent。”
public class MainActivity extends AppCompatActivity {
private EditText mSearchTerm;
private Button mRequestButton;
private String mQuery;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSearchTerm = (EditText) findViewById(R.id.ediText_search_term);
mRequestButton = (Button) findViewById(R.id.request_button);
mRequestButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mQuery = mSearchTerm.getText().toString();
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api.flickr.com/services/rest/")
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build();
ApiInterface apiInterface = retrofit.create(ApiInterface.class);
Call<List<Photo>> call = apiInterface.getPhotos(mQuery);
call.enqueue(new Callback<List<Photo>>() {
@Override
public void onResponse(Call<List<Photo>> call, Response<List<Photo>> response) {
}
@Override
public void onFailure(Call<List<Photo>> call, Throwable t) {
}
});
}
});
}
//Synchronous vs. Asynchronous
public interface ApiInterface {
@GET("?&method=flickr.photos.search&api_key=1c448390199c03a6f2d436c40defd90e&format=json") //
Call<List<Photo>> getPhotos(@Query("q") String photoSearchTerm);
}
}
最佳答案
基于他们的API docs,您希望将text
作为@Query
参数而不是q
传递。像这样:Call<List<Photo>> getPhotos(@Query("text") String photoSearchTerm);
其他事情:
•可能想从您的帖子中隐藏您的API密钥。
•可能想用onClick()
将代码包装在if(!TextUtils.isEmpty(mQuery))
方法中,以防止再次发生此问题。 (还可以将TextChangeWatcher添加到您的EditText中,并根据EditText中字符串的长度启用/禁用搜索按钮
