当我尝试使用firebase cli将此功能部署到Firebase时，它会在cli中给出错误。这个功能的作用是
exports.register = functions.https.onRequest((request, response) => {
const db = admin.firestore();
const user: string = request.body['username'];
const phone: number = request.body['phone'];
const password: string = request.body['password'];
return db.collection('rejectedContacts').where('contact', '==', phone).get()
.then(snapShot => {
if (snapShot.size > 0) {
return response.json(
{
status: 0,
message: `Contact, ${phone} is blocked, please try again with another number`,
result: null
}
);
} else {
return db.collection('users').where('contacts.phone', '==', phone).get()
.then(snapShot => {
if (snapShot.size > 0) {
return response.json(
{
status: 0,
message: `Contact, ${phone} is already assigned with an accont.
Did you forgot your pasword?`,
result: null
}
);
} else {
return db.collection('users').add(
{
user: user,
password: password,
isBlocked: false,
joiningDate: Date.now(),
phoneVerified: false,
deleted: false,
contacts:
{
phone: phone
}
}
).then((writeResult) => {
return response.json(
{
result: `User with ID: ${writeResult.id} added.`
}
);
});
}
});
}
});
});
我在cli中遇到的错误就是这个

但是当我将函数分成三个独立的函数时 （1.检查被拒绝的联系人，2。检查号码是否正在使用，3。注册号码）是否有效。我不想进行三次调用来注册用户，每个函数调用都计入云函数。
有人能说出代码有什么问题吗？
答案 0 :(得分：3)
项目中的TSLint预部署挂钩会给出一个错误和三个警告：
ERROR: /home/me/Documents/TfmFirebase/functions/src/index.ts[98, 27]: Shadowed name: 'snapShot'
WARNING: /home/me/Documents/TfmFirebase/functions/src/index.ts[140, 9]: Identifier 'phone' is never reassigned; use 'const' instead of 'let'.
WARNING: /home/me/Documents/TfmFirebase/functions/src/index.ts[141, 9]: Identifier 'password' is never reassigned; use 'const' instead of 'let'.
WARNING: /home/me/Documents/TfmFirebase/functions/src/index.ts[145, 9]: Identifier 'queryRef' is never reassigned; use 'const' instead of 'let'.
您不必修复警告，但必须修复错误（或禁用TSLint预部署挂钩）。
第一行中的错误表示您正在将一个变量名称与另一个变量名称相混淆。这有时表示编程错误。变量是snapShot，你使用它两次，一个嵌套在另一个函数内。您可以通过更改其中一个用途的名称来解决此问题，以便不重新定义另一个用途。
您还可以重构您的承诺，以便它们不会嵌套。
