MongoDB Stitch JWT 自定义身份验证:需要有效的 UID(介于 1 到 128 个字符之间)

Question

如何在节点.js中为 mongodb Atlas Cloud Stitch 设置所需的有效 UID(1 到 128 个字符之间(？我正在使用jasonwebtoken包来签署 Stitch 凭据的令牌：

Nodejs：

var token = jwt.sign(payload, Buffer.from(key), options);
credential = new CustomCredential(token);
stitchclient.auth.loginWithCredential(credential)
.then(authedUser => console.log(`logged in with custom auth as user ${authedUser.id}`))
.catch( err => console.error(`failed to log in with custom auth: ${err}`))

我可以发送，通过签名，但 Stitch 返回：

无法使用自定义身份验证登录：拼接服务错误：自定义无效 身份验证令牌：需要有效的 UID(介于 1 到 128 个字符之间(

Answer 1

更具体地说，例如，如果您从 Realm 函数生成令牌，您将从上下文中获取用户 ID：

exports = function(userMail) {
const jwt = require('jsonwebtoken')
const KEY_JWT = 'MY_SECRET_KEY'
const token = jwt.sign({
email: userMail, 
sub: context.user.id,
aud: "<application_id>"
},
KEY_JWT,
{
expiresIn: "1h"
}
)
return token
}

已解决：

在有效负载上预先设置：

"aud": "your api stitch id",
"sub": "your user custom api key"

var header = {
alg: "HS256",
typ: "JWT"
}
var payload = {
"aud": "your api stitch id",
"sub": "your user custom api key",
name : "name",
pass : "pass",
} 
var options = {
expiresIn : (60 * 60 * 24).toString(), // ONE DAY TO EXPIRATION
algorithm: 'HS256'
} 

后：

var token = jwt.sign(payload, Buffer.from("your user custom api key"), options);
credential = new CustomCredential(token);
stitchclient.auth.loginWithCredential(credential)
.then(authedUser => console.log(`logged in with custom auth as user ${authedUser.id}`))
.catch( err => console.error(`failed to log in with custom auth: ${err}`))
