請嘗試以下操作,這裏是您的generator類,它可能看起來像這樣。
public class ServiceGenerator {
public static String apiBaseUrl = "http://example/";
private static Retrofit retrofit;
private static Retrofit.Builder builder =
new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(apiBaseUrl);
private static OkHttpClient.Builder httpClient =
new OkHttpClient.Builder();
// No need to instantiate this class.
private ServiceGenerator() {
}
public static void changeApiBaseUrl(String newApiBaseUrl) {
apiBaseUrl = newApiBaseUrl;
builder = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(apiBaseUrl);
}
public static <S> S createService(Class<S> serviceClass, AccessToken token) {
String authToken = token.getTokenType().concat(token.getAccessToken());
return createService(serviceClass, authToken);
}
// more methods
// ...
}
之後,你可以在你的活動如下方式使用它,或者fragmen
public class DynamicBaseUrlActivity extends AppCompatActivity {
public static final String TAG = "CallInstances";
private Callback<ResponseBody> downloadCallback;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_file_upload);
downloadCallback = new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
Log.d(TAG, "server contacted at: " + call.request().url());
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
Log.d(TAG, "call failed against the url: " + call.request().url());
}
};
// first request
FileDownloadService downloadService = ServiceGenerator.create(FileDownloadService.class);
Call<ResponseBody> originalCall = downloadService.downloadFileWithFixedUrl();
originalCall.enqueue(downloadCallback);
// change base url
ServiceGenerator.changeApiBaseUrl("http://example/?p1=a&p2=b");
// new request against new base url
FileDownloadService newDownloadService = ServiceGenerator.create(FileDownloadService.class);
Call<ResponseBody> newCall = newDownloadService.downloadFileWithFixedUrl();
newCall.enqueue(downloadCallback);
}
}

它贏得」 t工作,方法** baseUrl()**不會包含參數,它可以改變baseUrl,但仍然在URL中丟失了參數y我們的方式。我想要的是當發送請求時,不要在URL中丟失參數。 – ChengTao
