javascript - 在我的谷歌登录代码中出现以前没有的错误

Question

我的项目中目前有这段代码：

后端：

app.post('/login', (req, res)=>{
    let token = req.header.token;

    async function verify() {
        const ticket = await client.verifyIdToken({
            idToken: id_token,
            audience: CLIENT_ID,
        });
        const payload = ticket.getPayload();
        const userid = payload['sub'];
        console.log(payload)
    }
    verify()
        .then(()=>{
            res.cookie('session-token', token);
            res.send('success');
        }).
    catch(console.error);
})

前端：

<script>
        function onSignIn(googleUser) {
            var id_token = googleUser.getAuthResponse().id_token;
            console.log(id_token)

            var xhr = new XMLHttpRequest();
            xhr.open('POST', '/login');
            xhr.setRequestHeader('Content-Type', 'application/json');
            xhr.onload = function() {
                console.log('Signed in as: ' + xhr.responseText);
                if(xhr.responseText == 'success'){
                    signOut();
                    location.assign('/dashboard');
                }
            };
            xhr.send(JSON.stringify({token: id_token}));
        }
    </script>

当我启动 localhost 并导航到 /login 路由时，我的终端中出现错误，并显示以下消息：

Error: The verifyIdToken method requires an ID Token

    at Function.process_params (/Users/gilmoreg01/Developer/pinventory/pinventory_backend/node_modules/express/lib/router/index.js:335:12)

我对正在发生的事情感到非常困惑，因为我之前有它工作过，自从它上次工作以来我没有改变任何东西。如果有人知道发生了什么，我很乐意知道。

谢谢！
