Javascript 如果我设置请求';s模式转换为';无cors';在我的firebase云函数中?
这是问题的后续行动。我有一个firebase函数,它应该接受OTP,验证它,然后根据用户密码是否正确来更改用户密码(出于某种原因,我无法使用firebase的内置密码重置功能)。以下是我的职责:Javascript 如果我设置请求';s模式转换为';无cors';在我的firebase云函数中?,javascript,firebase,cors,google-cloud-functions,es6-promise,Javascript,Firebase,Cors,Google Cloud Functions,Es6 Promise,这是问题的后续行动。我有一个firebase函数,它应该接受OTP,验证它,然后根据用户密码是否正确来更改用户密码(出于某种原因,我无法使用firebase的内置密码重置功能)。以下是我的职责: exports.resetPassword = functions.https.onCall((data, context) => { return new Promise((resolve, reject) => { if(data.sesId &&

当我运行该函数时,它会被执行,因为我可以在控制台语句中看到它,但我在客户端遇到以下错误
Access to fetch at 'https://us-central1-project-name.cloudfunctions.net/functionName' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
当我记录从函数收到的响应时,它显示{“code”:“internal”}
什么是cors包?我如何解决这个问题
第2部分(不相关) 另外,在函数的第11行和第12行,我使用
admin.auth().getUserByEmail(data.email).then(user => {
admin.auth().updateUser(user.uid, {password: data.password})
})
这是正确的吗
对于第1部分,我提到了这个问题,但它没有答案。看看可调用云函数的:
functions.https.HttpsError
的实例来正确管理错误李>
exports.resetPassword = functions.https.onCall((data, context) => {
if(data.sesId && data.otp){
let dataOptCorresponds = true;
return admin.firestore().collection('verification').doc(data.sesId).get()
.then(verSnp => {
if(verSnp.data().attempt != 'verified'){
var now = new Date().getTime()
if(verSnp.data().expiring > now){
if(data.email == verSnp.data().email){
if(verSnp.data().attempt > 0){
if(data.otp == verSnp.data().otp){
return admin.auth().getUserByEmail(data.email);
} else {
dataOptCorresponds = false;
var redAttempt = verSnp.data().attempt - 1
return admin.firestore().collection('verification').doc(data.sesId).update({
attempt: redAttempt
})

throw new Error('Incorrect OTP. You have exhausted your attempts. Please request a new OTP.')

throw new Error('OTP is invalid. Please request a new OTP.')

.then(user => {
if(dataOptCorresponds) {
return admin.auth().updateUser(user.uid,{
password: data.password
})
} else {
throw new Error(`Incorrect OTP. You have xxxx attempts remaining.`)
}
})
.then(() => {
return admin.firestore().collection('verification').doc(data.sesId).update({
attempt: 'verified'
})
.then(() => {
return {result: "success"}
})
.catch(error => {
throw new functions.https.HttpsError('internal', error.message);
})
} else {
throw new functions.https.HttpsError('invalid-argument', 'Enter OTP');
}
})
更新以下Bergi的评论: 如果您希望能够区分返回到前端的错误类型(特别是在OTP不正确、无效或过期或电子邮件不正确的情况下发回
无效参数HttpsError
),您可以在then()
方法中使用第二个参数
exports.resetPassword = functions.https.onCall((data, context) => {
if(data.sesId && data.otp){
let dataOptCorresponds = true;
return admin.firestore().collection('verification').doc(data.sesId).get()
.then(
verSnp => {
if(verSnp.data().attempt != 'verified'){
var now = new Date().getTime()
if(verSnp.data().expiring > now){
if(data.email == verSnp.data().email){
if(verSnp.data().attempt > 0){
if(data.otp == verSnp.data().otp){
return admin.auth().getUserByEmail(data.email);
} else {
dataOptCorresponds = false;
var redAttempt = verSnp.data().attempt - 1
return admin.firestore().collection('verification').doc(data.sesId).update({
attempt: redAttempt
})
}
} else {
throw new Error('Incorrect OTP. You have exhausted your attempts. Please request a new OTP.')
}
} else {
throw new Error('Incorrect email. How did you get here?')
}
} else {
throw new Error('OTP is expired. Please request a new OTP.')
}
} else {
throw new Error('OTP is invalid. Please request a new OTP.')
}
},
error => {
throw new functions.https.HttpsError('invalid-argument', error.message);
}
)
.then(user => {
if(dataOptCorresponds) {
return admin.auth().updateUser(user.uid,{
password: data.password
})
} else {
throw new Error(`Incorrect OTP. You have xxxx attempts remaining.`)
}
})
.then(() => {
return admin.firestore().collection('verification').doc(data.sesId).update({
attempt: 'verified'
})
.then(() => {
return {result: "success"}
})
.catch(error => {
throw new functions.https.HttpsError('internal', error.message);
})
} else {
throw new functions.https.HttpsError('invalid-argument', 'Enter OTP');
}
})
最后使用.catch()
时,所有抛出的n错误最终都会成为内部HttpsError
。你需要把它向上移动,否则。@Bergi谢谢你的“提示”!我试着修改答案。如果你能看一看并确认这是正确的方法,那就太好了!然而,我不知道如何实现第二个then()
参数,其中我们有if(dataOptCorresponds)
,因为错误是dataOptCorresponds
值的函数……噢,忘了我刚才说的。我没有正确阅读您的答案,也没有意识到您实际上希望所有错误消息都包装在HttpsError
中。我想你最初的方法是正确的。伙计们,我真的很感谢你们的帮助,但是因为假期我一周都不在办公桌旁。我会在有机会试用代码后立即回复。@VaibhavJoshi为什么不使用更新3个不同集合中的多个文档?
