我正在使用Retrofit 2.0
和Jackson
轉換器與Rest API進行通信。部分請求需要授權令牌。如果我擁有的令牌已經過期,我需要用另一個請求刷新它們,並重覆上次因此而失敗的請求。Android Retrofit 2.0刷新標記
我的問題:我是否需要手動每次都做,或者有什麼方法可以自動化嗎?
這裏就是這樣,我在那一刻實現它:
TrackerService
public interface TrackerService {
@POST("auth/sendPassword")
Call<ResponseMessage> sendPassword(@Header("app-type") String appType,
@Body User userMobile);
@FormUrlEncoded
@POST("oauth/token")
Call<TokenResponse> oathToken(@Field("client_id") String clientId,
@Field("client_secret") String clientSecret,
@Field("grant_type") String grantType,
@Field("username") String username,
@Field("password") String password);
@FormUrlEncoded
@POST("oauth/token")
Call<TokenResponse> refreshToken(@Field("client_id") String clientId,
@Field("client_secret") String clientSecret,
@Field("grant_type") String grantType,
@Field("refresh_token") String username);
@PUT("me/profile")
Call<Profile> updateProfile(@Header("app-type") String appType,
@Header("Authorization") String token,
@Body Profile profile);
}
ServiceGateway
public class ServiceGateway {
private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
private static Retrofit retrofit;
public static <S> S createService(Class<S> serviceClass) {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(20 * 1000, TimeUnit.MILLISECONDS)
.writeTimeout(20 * 1000, TimeUnit.MILLISECONDS)
.readTimeout(20 * 1000, TimeUnit.MILLISECONDS)
.addInterceptor(interceptor).build();
Retrofit.Builder builder =
new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(JacksonConverterFactory.create());
retrofit = builder.client(httpClient.build())
.client(client)
.build();
return retrofit.create(serviceClass);
}
public static Retrofit getRetrofit() {
return retrofit;
}
}
我如何調用函數,把它當令牌過時
trackerService = ServiceGateway.createService(TrackerService.class);
Call<Profile> call = trackerService.updateProfile(getString(R.string.app_type), "Bearer " + userPrefs.accessToken().get(),
new Profile(trimedInvitationMessage, title,
String.valueOf(selectedCountry.getCountryCode()), mobilePhone, countryISO, fullName));
call.enqueue(new Callback<Profile>() {
@Override
public void onResponse(Call<Profile> call, Response<Profile> response) {
if (response.body() != null) {
} else {
if (response.raw().code() == 401) {
Call<TokenResponse> refreshTokenCall = trackerService.refreshToken(userPrefs.clientId().get(),
userPrefs.clientSecret().get(), "refresh_token", userPrefs.refreshToken().get());
refreshTokenCall.enqueue(new Callback<TokenResponse>() {
@Override
public void onResponse(Call<TokenResponse> call, Response<TokenResponse> response) {
if (response.body() != null) {
updateAdviserProfile(trimedInvitationMessage, title, mobilePhone, countryISO, fullName);
} else {
userPrefs.clear();
Intent intent = new Intent(WelcomeActivity_.launcher(EditProfileActivity.this));
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
startActivity(WelcomeActivity_.launcher(EditProfileActivity.this));
}
}
@Override
public void onFailure(Call<TokenResponse> call, Throwable t) {
}
});
} else if (response.raw().code() == 422)
}
}
@Override
public void onFailure(Call<Profile> call, Throwable t) {
}
});
PLUS ONE用於解釋OKHttp Authenticator在簡單單詞中的角色。這有很大幫助 – Rinav
