我正在尝试添加 Google 身份验证，但遇到了一个问题：
我正在使用这个回购代码：https ://github.com/conorbailey90/Google-Auth
这里我有前端代码。这只是向id_token服务器发送一个带有 json 格式的 post 请求而已：
function onSignIn(googleUser) {
var id_token = googleUser.getAuthResponse().id_token; // get the id_token and send it to server
// send the id_token to server using a simple post request
var xhr = new XMLHttpRequest();
xhr.open('POST', '/google-login');
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.onload = function() {
// console.log('Signed in as: ' + xhr.responseText);
if(xhr.responseText == 'success'){
signOut();
// location.assign('/profile')
}
};
xhr.send(JSON.stringify({token : id_token}));
}
在我的 server.js 中：（注意我向你展示了我CLIENT_ID是否想在你身边测试这个）
const {OAuth2Client} = require('google-auth-library');
const CLIENT_ID = '203772907695-qd52ou2r1bcsht8f515lh63cpqaateq2.apps.googleusercontent.com'
const client = new OAuth2Client(CLIENT_ID);
app.post('/google-login',async (req, res) => {
let token = req.body.token;
console.log('token', token); // I get the token which is sent from front-end successfully
// I can successfully get the data from a simple post request to this endpoint so I'm sure there is nothing wrong with the token and its valid
const resp = await axios.post(`https://oauth2.googleapis.com/tokeninfo?id_token=${token}`);
console.log('res', resp)
async function verify() {
// the verifyIdToken function below causes the error
const ticket = await client.verifyIdToken({
idToken: token,
audience: CLIENT_ID, // Specify the CLIENT_ID of the app that accesses the backend
});
// because the above error I never reach here
const payload = ticket.getPayload();
const userid = payload['sub'];
}
verify()
.then((e)=> {
res.send('success')
})
.catch(err => console.log(err));
})
如您所见，该verifyIdToken函数会导致以下错误，而我确信令牌 100% 有效：

错误中的第一句话是：
GaxiosError：检索验证证书失败：
我们看到这个错误有点低：
您的客户端无权
/oauth2/v1/certs从此服务器获取 URL。我们知道的就这些。
这是我的谷歌控制台配置（也许我在这里有错误）：
