无法将云功能部署到 Firebase

Question

当我尝试使用 firebase cli 将此功能部署到 Firebase 时，它​​在 cli 中出现错误。这个函数的作用是

1. 检查给定号码是否被阻止，如果被阻止，它将发送响应。
2. 如果号码没有被拒绝，它会检查该号码是否与另一个帐户相关联，如果是，它会发送响应
3. 如果1和2都为假，则注册用户。

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 中遇到的错误是这样的

但是当我将函数分成三个单独的函数时 （1.检查被拒绝的联系，2.检查号码是否正在使用，3.注册号码）它起作用了。有点我不想进行三个调用来注册用户，并且每个函数调用都计入云函数中。

谁能告诉代码有什么问题？

您项目中的 TSLint 预部署钩子给您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）。

第一行的错误是说你正在用另一个变量名隐藏一个变量名。这有时表示编程错误。变量是snapShot，您使用了两次，一次嵌套在另一个函数中。您可以通过更改其中一种用途的名称来解决此问题，以免重新定义另一种用途。

您还可以重组您的承诺，使其不嵌套。
