Sign in with Apple
首先要在苹果开发者账号里设置一些东西，可参考
https://www.jianshu.com/p/e1284bd8c72a
客户端使用苹果登录，服务器端使用node验证，代码中包含 iOS和nodejs https://github.com/Hwangkop/iOSSignAndNode
服务端要做的其实很简单
nodejs需要装三个东西
npm install node-rsa
npm install axios
npm install jsonwebtoken
提供一个接口让客户端上传他那边获取到的identity
当客户端通过请求你提供的接口时，服务端可以使用axios请求这个接口 https://appleid.apple.com/auth/keys
，直接调用便会获取到一个 JWK，获取到的信息如下
{
"keys": [
{
"kty": "RSA",
"kid": "AIDOPK1",
"use": "sig",
"alg": "RS256",
"n": "lxrwmuYSAsTfn-lUu4goZSXBD9ackM9OJuwUVQHmbZo6GW4Fu_auUdN5zI7Y1dEDfgt7m7QXWbHuMD01HLnD4eRtY-RNwCWdjNfEaY_esUPY3OVMrNDI15Ns13xspWS3q-13kdGv9jHI28P87RvMpjz_JCpQ5IM44oSyRnYtVJO-320SB8E2Bw92pmrenbp67KRUzTEVfGU4-obP5RZ09OxvCr1io4KJvEOjDJuuoClF66AT72WymtoMdwzUmhINjR0XSqK6H0MdWsjw7ysyd_JhmqX5CAaT9Pgi0J8lU_pcl215oANqjy7Ob-VMhug9eGyxAWVfu_1u6QJKePlE-w",
"e": "AQAB"
}
]
}
我们要通过上面的keys里面的第一个对象去获取 Public Key,这里需要解码才能得到 Public Key，可以使用 node-rsa
let res = await axios.request({
method: "GET",
url: "https://appleid.apple.com/auth/keys",
})
let key = res.data.keys[0]
const pubKey = new NodeRSA();
pubKey.importKey({ n: Buffer.from(key.n, 'base64'), e: Buffer.from(key.e, 'base64') }, 'components-public');
let data = {publicKey: pubKey.exportKey(['public']), alg: key.alg}
- 然后使用 jsonwebtoken 解码获取用户信息
let payload = jwt.decode(identity,data.publicKey,data.alg)
打印 payload 会得到以下信息，sub就是用户的唯一标示
{
"iss": "https://appleid.apple.com",
"aud": "这个对应app的bundleid",
"exp": 1567494694,
"iat": 1567494094,
"sub": "这个字段和手机端获取的user信息相同",
"c_hash": "nRYP2wGXBGT0bIYWibx4Yg",
"auth_time": 1567494094
}
但是是需要验证的
jwt.verify(identity,data.publicKey,(error,decoded)=>{
payload = decoded;
});
服务端整体代码
router.get('/auth', async ctx => {
var data = await getPublicKey()
let identity = ctx.query.identity
//解码获得用户信息
~~ let payload = jwt.decode(identity,data.publicKey,data.alg)~~
jwt.verify(identity,data.publicKey,(error,decoded)=>{
payload = decoded;
console.log(payload)
});
})
async function getPublicKey() {
let res = await axios.request({
method: "GET",
url: "https://appleid.apple.com/auth/keys",
})
let key = res.data.keys[0]
const pubKey = new NodeRSA();
pubKey.importKey({ n: Buffer.from(key.n, 'base64'), e: Buffer.from(key.e, 'base64') }, 'components-public');
let data = {publicKey: pubKey.exportKey(['public']), alg: key.alg}
return data;
}
