Javascript 解析服务器中如何处理apple回调

我与苹果的登录工作到我与苹果的登录点，苹果通过Post请求重定向到我的服务器

我设置了以下express post处理程序：

app.post('/apple-callback', async function (req, res) {
    let data = req.body.id_token
    let buff = Buffer.from(data.split('.')[1], 'base64')
    let text = buff.toString('utf8')
    let json = JSON.parse(text)
    try {
        let currentUser = await Parse.User.logInWith('apple', {
            'authData':{
                'id': json.sub,
                'token': data
            } 
        })

        console.info(currentUser)
    } catch (error) {
        console.error(error)
    }

    res.json({
        'fissa': req.body,
        'state': req.body.state,
        'code': req.body.code,
        'idToken': req.body.id_token,
        json,
        sub: json.sub
    })
})

但我得到了以下错误：

有什么建议吗

这就是我所取得的成绩和一些尝试和错误

---

但我不知道如何修复错误并获得有效的解析用户。

因此，解析服务器中出现了一个错误，苹果开始托管多个公钥（因此该密钥并不总是与签名的jwt匹配），而身份验证适配器不支持该公钥。现在，修复程序已经合并到master中，并将在下一个版本中发布，此时我在问题中使用的代码可以正常工作

仅供参考：

为什么不使用

const json=json.parse（atob（data.split（“.”[1]））.sub

？据我所知，atob在节点中不可用。所以我使用了一个缓冲区来确定。可能没关系，但atob意味着解码为ascii码。你试过了吗<代码>buff.toString（'ascii'）啊，我没有意识到，不幸的是，更改它并不能更改我得到的错误。@stephan我在使用parse和apple登录时遇到了完全相同的错误。你已经设法解决了这个问题吗？
