前言
公司做海外產品的，集成的是 google 賬號登錄，賬號信息、郵箱等這些不涉及隱私的按 google 的正常登錄流程可以輕鬆實現 。但是一旦需要獲取涉及隱私的信息就比較麻煩，文檔也不是十分清晰，非常難找，很多坑。
google 賬號登錄

https://developers.google.com/identity/sign-in/android/sign-in
google 賬號登錄接入的坑：
- 申請的
client_id必須是 api console 後臺 ：https://console.cloud.google.com/apis 與 google play 後臺對應的應用關聯起來。 client_id下的簽名信息和報名信息必須和測試時的 apk 的簽名信息和報名信息一致。- 在 google play 下啓動 google 的二次簽名，則 api console 後臺的簽名信息是二次簽名後的信息。打包測試時使用上傳 到 Google play 後臺的 apk 的簽名證書即可。
google 登錄的流程在這個文檔寫的比較清楚了：https://developers.google.com/identity/sign-in/android/sign-in，這裏大致說一下，不貼代碼了
- 構建需求請求的內容：
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.requestIdToken("your client_id")
.build();
// Build a GoogleSignInClient with the options specified by gso.
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
2.發起登錄請求，跳轉 google 登錄頁面。
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);
- 獲取 Google 登錄返回
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
// The Task returned from this call is always completed, no need to attach
// a listener.
Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
handleSignInResult(task);
}
}
- 獲取 用戶 id token,傳到你自己的 服務端 做驗證
private void handleSignInResult(Task<GoogleSignInAccount> completedTask) {
try {
GoogleSignInAccount account = completedTask.getResult(ApiException.class);
// Signed in successfully, show authenticated UI.
} catch (ApiException e) {
// The ApiException status code indicates the detailed failure reason.
// Please refer to the GoogleSignInStatusCodes class reference for more information.
Log.w(TAG, "signInResult:failed code=" + e.getStatusCode());
}
}
- 切換賬號
/**
* 重新獲取賬號列表
*/
public void revokeAccess() {
try {
if (mGoogleSignInClient!=null && mActivity!=null){
mGoogleSignInClient.revokeAccess().addOnCompleteListener(mActivity, new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
Log.d(TAG, "onComplete: ");
}
});
}
} catch (Exception e){
e.printStackTrace();
}
}
獲取公開資料和需要特別授權的信息（性別、生日等）
1、在構建請求是新增獲取 的公共資料信息 及 需要獲取的特殊信息
private static final String GENDER_SCOPE = "https://www.googleapis.com/auth/user.gender.read";
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.requestIdToken("your client_id")
.requestScopes(new Scope(GENDER_SCOPE));
.build();
// Build a GoogleSignInClient with the options specified by gso.
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
需要請求的信息可在如下鏈接查找：https://developers.google.com/people/api/rest/v1/people/get
2、檢測是否有權限
GoogleSignInAccount lastSignedInAccount = GoogleSignIn.getLastSignedInAccount(mActivity);
Scope scope = new Scope(GENDER_SCOPE);
if (Utils.isNeedRequest() && !GoogleSignIn.hasPermissions(lastSignedInAccount,scope)){
SGLog.d(TAG+" need requst permission...");
GoogleSignIn.requestPermissions(mActivity,RC_GET_TOKEN,lastSignedInAccount,scope);
}
注意：這一步不需要也可以，有這一步會出現一個 “再確認” 的授權頁面，沒有也不影響獲取的信息。
3、跳轉登錄頁面 （同以上 google 賬號登錄）
4、獲取登錄信息 （同以上 Google賬號登錄）
5、開啓線程獲取 特殊信息
getProfileAsyncTask = new GetProfileAsyncTask(mActivity, new GpProfileInfoCallback() {
@Override
public void onGetProfileInfo(Person person) {
SGLog.d(TAG+" onGetProfileInfo... ");
getProfileInfo(person);
}
});
getProfileAsyncTask.execute(signInAccount);
異步任務
// Global instance of the HTTP transport
private static final HttpTransport HTTP_TRANSPORT = AndroidHttp.newCompatibleTransport();
// Global instance of the JSON factory
private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
private static class GetProfileAsyncTask extends AsyncTask<GoogleSignInAccount, Void, Person> {
// Retrieved from the sigin result of an authorized GoogleSignIn
private WeakReference<Activity> mActivityRef;
private GpProfileInfoCallback mProfileInfoCallback;
public GetProfileAsyncTask(Activity activity,GpProfileInfoCallback callback) {
mActivityRef = new WeakReference<>(activity);
mProfileInfoCallback = callback;
}
@Override
protected Person doInBackground(GoogleSignInAccount... params) {
if (mActivityRef.get() == null){
SGLog.d(TAG+" GetProfileAsyncTask doInBackground activity is null.");
return null;
}
GoogleSignInAccount signInAccount = params[0];
Context context = mActivityRef.get().getApplicationContext();
GoogleAccountCredential credential = GoogleAccountCredential.usingOAuth2(
context,
Collections.singleton(GENDER_SCOPE));
credential.setSelectedAccount(signInAccount.getAccount());
SGLog.d(TAG+" get profile info start.");
PeopleService service =
new PeopleService.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)
.setApplicationName(ApkUtils.getAppName(context)) // your app name
.build();
SGLog.d(TAG+" get profile info start.");
// Get info. on user
Person person =null;
try {
person = service
.people()
.get("people/me")
.setPersonFields("genders")
.execute();
SGLog.d(TAG+" getPerson end.");
// return the result
if (mProfileInfoCallback!=null){
mProfileInfoCallback.onGetProfileInfo(person);
}
} catch (Exception e) {
SGLog.e(TAG+e.getMessage());
if (mProfileInfoCallback!=null){
mProfileInfoCallback.onGetProfileInfo(null);
}
e.printStackTrace();
}
return person;
}
@Override
protected void onPostExecute(Person aVoid) {
super.onPostExecute(aVoid);
}
}
獲取性別信息
private void getProfileInfo(Person person){
SGLog.d(TAG+" executeProfileInfo...");
if (person == null){
notifyResult(mLastUser,Utils.SUCCESS);
}else {
try {
List<Gender> genders = person.getGenders();
Gender gender = genders.get(0);
String value = gender.getValue();
SGLog.d(TAG+" genders:"+genders.size()+ " gender:"+value);
mLastUser.setGender(value);
notifyResult(mLastUser,Utils.SUCCESS);
}catch (Exception e){
SGLog.e(TAG+" getProfileInfo error.");
notifyResult(null,SGErrorCode.LOGIN_FAILED);
e.printStackTrace();
}
}
}
