Android 中有效的 google 帐户 OAuth 2 令牌

Question

我对 Google 帐户 OAuth 2 令牌有疑问。 我们需要令牌来访问帐户信息（数字 ID、电子邮件、用户名） 在 AccountManager 中请求 getAuthToken(account, SCOPE, options, mContext, getAuthTokenCallback, null) 后，token 无法访问账户信息。 HTTP请求的响应https://www.googleapis.com/plus/v1/people/me（标头“授权：OAuth ya29.AHES6ZSuMvL3FoxqXfevYevWyEmTPOE1HXW7_Tj6l3UAN-2J7kTs0-I”）

{
    "error": {
    "errors": [
        {
         "domain": "usageLimits",
         "reason": "dailyLimitExceededUnreg",
         "message": "Daily Limit Exceeded. Please sign up",
         "extendedHelp": "https://code.google.com/apis/console"
        }
    ],
    "code": 403,
    "message": "Daily Limit Exceeded. Please sign up"
    }
}

为什么会出现这个错误？ 以前使用由空格分隔的两种类型的 AuthSub 令牌。(SCOPE_OLD_PERMITIONS) 现在它不起作用并导致 java.io.IOException

如何获取有效令牌？

这是获取令牌的请求：

TCGoogleAccountsManager mng = new TCGoogleAccountsManager(this);
mng.requestAccountOAuthToken(this, acc);

帮助获取令牌的类：

public class TCGoogleAccountsManager {
private static final String CLIENT_SECRET = ...;
private static final String CLIENT_ID = ...;
private static final String SCOPE_CONTACTS_API = "cp";
private static final String SCOPE_ANDROID_API = "android";
private static final String SCOPE_GOOGPE_PLUS = "oauth2:https://www.googleapis.com/auth/plus.me";
private static final String SCOPE_MY_INFO = "oauth2:https://www.googleapis.com/auth/userinfo.email";
private static final String SCOPE_OLD_PERMITIONS = "oauth2:https://www-opensocial.googleusercontent.com/api/people/ oauth2:https://www.googleapis.com/auth/userinfo#email";
private static final String SCOPE = SCOPE_GOOGPE_PLUS;
private static final String COM_GOOGLE = "com.google";

private AccountManager mManager;
private OnGetOAuthTokenRequestCompletedListener mTokenRequestListener;

public TCGoogleAccountsManager(Context ctx) {
    mManager = AccountManager.get(ctx.getApplicationContext());
    mTokenRequestListener = new GoogleTokenListener(
            ctx.getApplicationContext());
}

public int getAccountsNumber() {
    return mManager.getAccountsByType(COM_GOOGLE).length;
}

public Account[] getGoogleAccounts() {
    return mManager.getAccountsByType(COM_GOOGLE);
}


public Account getGoogleAccountByName(String name) {
    Account foundAcc = null;
    if (name != null && !name.equals("")) {
        Account[] googleAccounts = mManager.getAccountsByType(COM_GOOGLE);
        for (int i = 0; i < googleAccounts.length; i++) {
            if (name.equals(googleAccounts[i].name)) {
                foundAcc = googleAccounts[i];
                break;
            }
        }
    }
    return foundAcc;
}


public Account getGoogleAccount(int index) {
    return getGoogleAccounts()[index];
}

public void requestAccountOAuthToken(Activity mContext, Account account) {
    try {
        final Bundle options = new Bundle();
        options.putString("client_id", CLIENT_ID);
        options.putString("client_secret", CLIENT_SECRET);
        mManager.getAuthToken(account, SCOPE, options, mContext,
                getAuthTokenCallback, null);
    } catch (Exception e) {
        e.printStackTrace();
    }
}


private AccountManagerCallback<Bundle> getAuthTokenCallback = new AccountManagerCallback<Bundle>() {
    public void run(AccountManagerFuture<Bundle> future) {
        try {
            final Bundle result = future.getResult();
            final String accountName = result
                    .getString(AccountManager.KEY_ACCOUNT_NAME);
            final String authToken = result
                    .getString(AccountManager.KEY_AUTHTOKEN);
            boolean success = (accountName != null && authToken != null);
            if (!success) {
                if (mTokenRequestListener != null) {
                    mTokenRequestListener.onRequestCompleted(false,
                            accountName, authToken);
                }
            } else {
                // refresh token. We need fresh token.
                mManager.invalidateAuthToken(COM_GOOGLE, authToken);
                mManager.getAuthToken(getGoogleAccountByName(accountName),
                        SCOPE, false, getAuthTokenCallbackInvalidated, null);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
};


private AccountManagerCallback<Bundle> getAuthTokenCallbackInvalidated = new AccountManagerCallback<Bundle>() {
    public void run(AccountManagerFuture<Bundle> future) {
        try {
            final Bundle result = future.getResult();
            final String accountName = result
                    .getString(AccountManager.KEY_ACCOUNT_NAME);
            final String authToken = result
                    .getString(AccountManager.KEY_AUTHTOKEN);
            boolean success = (accountName != null && authToken != null);
            if (mTokenRequestListener != null)
                mTokenRequestListener.onRequestCompleted(success,
                        accountName, authToken);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
};
}

感谢和问候。

您需要一个用于 OAuth2 的 client_id，您可以通过在 https://code.google.com/apis/console 注册您的应用程序来获取它
