前言
公司做海外产品的，集成的是 google 账号登录，账号信息、邮箱等这些不涉及隐私的按 google 的正常登录流程可以轻松实现 。但是一旦需要获取涉及隐私的信息就比较麻烦，文档也不是十分清晰，非常难找，很多坑。
google 账号登录
官方链接：https://developers.google.com/identity/sign-in/android/start
https://developers.google.com/identity/sign-in/android/sign-in
google 账号登录接入的坑：
- 申请的
client_id必须是 api console 后台 ：https://console.cloud.google.com/apis 与 google play 后台对应的应用关联起来。 client_id下的签名信息和报名信息必须和测试时的 apk 的签名信息和报名信息一致。- 在 google play 下启动 google 的二次签名，则 api console 后台的签名信息是二次签名后的信息。打包测试时使用上传 到 Google play 后台的 apk 的签名证书即可。
google 登录的流程在这个文档写的比较清楚了：https://developers.google.com/identity/sign-in/android/sign-in，这里大致说一下，不贴代码了
- 构建需求请求的内容：
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.发起登录请求，跳转 google 登录页面。
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);
- 获取 Google 登录返回
@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);
}
}
- 获取 用户 id token,传到你自己的 服务端 做验证
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());
}
}
- 切换账号
/**
* 重新获取账号列表
*/
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();
}
}
获取公开资料和需要特别授权的信息（性别、生日等）
1、在构建请求是新增获取 的公共资料信息 及 需要获取的特殊信息
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);
需要请求的信息可在如下链接查找：https://developers.google.com/people/api/rest/v1/people/get
2、检测是否有权限
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：这一步不需要也可以，有这一步会出现一个 “再确认” 的授权页面，没有也不影响获取的信息。
3、跳转登录页面 （同以上 google 账号登录）
4、获取登录信息 （同以上 Google账号登录）
5、开启线程获取 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);
异步任务
// 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);
}
}
获取性别信息
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();
}
}
}
