我正在使用适用于 android 的 Google 身份工具包为我的应用程序的用户提供一种无需记住新密码即可注册/登录的方式,并为我省去安全保存所有密码的麻烦。
这是我在 Android 上的代码,它基本上将带有 POST 的 IdToken 字符串发送到我的 Node.js 服务器。效果很好,IdTokenString 使用 https 发送到我的服务器。
// Step 1: Create a GitkitClient.
// The configurations are set in the AndroidManifest.xml. You can also set or overwrite them
// by calling the corresponding setters on the GitkitClient builder.
//
client = GitkitClient.newBuilder(this, new GitkitClient.SignInCallbacks() {
// Implement the onSignIn method of GitkitClient.SignInCallbacks interface.
// This method is called when the sign-in process succeeds. A Gitkit IdToken and the signed
// in account information are passed to the callback.
@Override
public void onSignIn(IdToken idToken, GitkitUser user) {
showProfilePage(idToken, user);
// Now use the idToken to create a session for your user.
// To do so, you should exchange the idToken for either a Session Token or Cookie
// from your server.
// Finally, save the Session Token or Cookie to maintain your user's session.
final JSONObject sendJson = new JSONObject();
try {
sendJson.put("tokenString", idToken.getTokenString());
} catch (JSONException ex) {
ex.printStackTrace();
}
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... arg) {
try {
//Retrieve the logintoken from the server
HttpUtils.postSecure(Util.Constants.httpsServerUrl + "/registerwithtoken", sendJson.toString().getBytes("UTF-8"));
} catch (IOException ex) {
ex.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void nothing) {
}
}.execute();
在我的 Node.js 服务器上,我使用以下代码检索 IdToken 字符串:
function registerWithToken(req, res) {
var tokenString = req.body.tokenString;
if(typeof tokenString == "undefined") {
res.status(500).send('Tokenstring is undefined!');
}
console.log("INCOMING REGISTER WITH TOKEN");
console.log(req.body);
var decodedJWT = jwt.decode(tokenString, {complete: true});
var idToken = decodedJWT.payload.toString();
console.log(idToken);
gitkitClient.verifyGitkitToken(idToken, function (err, resp) {
if (err) {
console.log("INVALID TOKEN!! "+err);
res.status(500).send('Invalid token: ' + err);
} else {
//valid token!
console.log("VALID TOKEN SEND JWT BACK TO ANDROID");
}
});
}
我现在的问题是 node.js gitkitClient 总是返回 Token 无效,但我不知道为什么。
我的 idToken 似乎是正确的:
{ iss: 'https://identitytoolkit.google.com/',
aud: '*devConsoleNumbers*.apps.googleusercontent.com',
iat: 1449712391,
exp: 1450921991,
user_id: '*numbers*',
email: '*mail*',
provider_id: 'google.com',
verified: true,
display_name: '*John Doe*' }
错误行打印到控制台:
INVALID TOKEN!! Unable to verify the ID Token: Wrong number of segments in token: [object Object]
我不知道为什么验证失败。
这个问题有解决方案吗?
