您好我在不使用OAuth 2.0客户端ID和范围的情况下获得了Google +访问令牌。但是使用此访问令牌不会获取电子邮件地址。如何获取用户电子邮件地址?
使用和不使用OAuth 2.0客户端ID的accesstoken之间是否有任何区别?
我使用了以下代码,
String accessToken="";
try {
accessToken = GoogleAuthUtil.getToken(
getApplicationContext(),
mPlusClient.getAccountName(), "oauth2:"
+ Scopes.PLUS_LOGIN + " "
+ Scopes.PLUS_PROFILE);
System.out.println("Access token==" + accessToken);
} catch (Exception e) {
e.printStackTrace();
}

有两种简单的方法可以从Google +获取用户电子邮件,
1.通过下面的Plus.AccountApi.getAccountName
,
String email = Plus.AccountApi.getAccountName(mGoogleApiClient);
2.通过以下plus.profile.emails.read scope and REST end point
,
获取GooglePlus AccessToken
您需要通过" https://www.googleapis.com/auth/plus.profile.emails.read"
此范围从GooglePlus获取AccessToken
,如下所示
accessToken = GoogleAuthUtil.getToken(
getApplicationContext(),
mPlusClient.getAccountName(), "oauth2:"
+ Scopes.PLUS_LOGIN + " "
+ Scopes.PLUS_PROFILE+" https://www.googleapis.com/auth/plus.profile.emails.read");
对端点进行REST调用并执行简单的JSON解析
https://www.googleapis.com/plus/v1/people/me?access_token=XXXXXXXXXXXXX
您必须在<uses-permission android:name="android.permission.GET_ACCOUNTS" />
中声明权限AndroidManifest.xml
才能使用这些方法。
Google Developer网站的完整示例
执行以下操作,从Google plus中检索经过身份验证的用户的电子邮件,
class UserInfo {
String id;
String email;
String verified_email;
}
final String account = Plus.AccountApi.getAccountName(mGoogleApiClient);
AsyncTask<Void, Void, String> task = new AsyncTask<Void, Void, String>() {
@Override
protected UserInfo doInBackground(Void... params) {
HttpURLConnection urlConnection = null;
try {
URL url = new URL("https://www.googleapis.com/plus/v1/people/me");
String sAccessToken = GoogleAuthUtil.getToken(EmailTest.this, account,
"oauth2:" + Scopes.PLUS_LOGIN + " https://www.googleapis.com/auth/plus.profile.emails.read");
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty("Authorization", "Bearer " + sAccessToken);
String content = CharStreams.toString(new InputStreamReader(urlConnection.getInputStream(),
Charsets.UTF_8));
if (!TextUtils.isEmpty(content)) {
JSONArray emailArray = new JSONObject(content).getJSONArray("emails");
for (int i = 0; i < emailArray.length; i++) {
JSONObject obj = (JSONObject)emailArray.get(i);
// Find and return the primary email associated with the account
if (obj.getString("type") == "account") {
return obj.getString("value");
}
}
}
} catch (UserRecoverableAuthException userAuthEx) {
// Start the user recoverable action using the intent returned by
// getIntent()
startActivityForResult(userAuthEx.getIntent(), RC_SIGN_IN);
return;
} catch (Exception e) {
// Handle error
// e.printStackTrace(); // Uncomment if needed during debugging.
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
return null;
}
@Override
protected void onPostExecute(String info) {
// Store or use the user's email address
}
};
task.execute();
