因此，當我訪問 SvelteKit 發布端點時，如果我提交一些值并且它們沒有通過驗證檢查，它就可以正常作業。它回傳正確的狀態和正文。但是，當它插入資料庫時??，端點回傳 404 錯誤，但它會將用戶插入資料庫中。我認為這是因為 DB 呼叫是異步的并且 SvelteKit 沒有等待結果回傳，但不確定如何更改我的代碼，以便它等待并發送正確的 json 回應。

謝謝你的幫助！

import type { EndpointOutput } from '@sveltejs/kit';

    const bcryptPassword = await bcrypt.hash(password, 10);
    const emailToken = randomUUID();
    // double check the validation on the fields in case user submits directly to this endpoint.
    if (validation.validateEmail(email) == false) {
        //console.log(email);
        return {
            status: 422,
            body: {

                }
            };
        }
    );
}

更新修復

我最終使用 pg-promise 包而不是 pg 包來連接我的資料庫。

以下是更新后的代碼，以防有人遇到類似問題。

import type { EndpointOutput } from '@sveltejs/kit';
import bcrypt from 'bcrypt';
import { randomUUID } from 'crypto';
import { roles } from '$lib/config/roles.js';
import validation from '$lib/_helpers/validation';
import { db } from '$lib/config/db.js';

export async function post({
    body
}: {
    body: { firstName: string; lastName: string; emailAddress: string; password: string };
}): Promise<EndpointOutput> {
    //lets trim any whitespace on the fields
    console.log(body);
    const firstName = body?.firstName.trim();
    const lastName = body?.lastName.trim();
    const email = body?.emailAddress.trim();
    const password = body?.password.trim();
    const userRole = roles.web   roles.anonymous;
    const bcryptPassword = await bcrypt.hash(password, 10);
    const emailToken = randomUUID();
    // double check the validation on the fields in case user submits directly to this endpoint.
    if (validation.validateEmail(email) == false) {
        //console.log(email);
        return {
            status: 422,
            body: {
                message: 'Please enter a valid email address.'
            }
        };
    }
    if (validation.validatePassword(password) == false) {
        return {
            status: 422,
            body: {
                message: 'Password must be at least 6 characters.'
            }
        };
    }
    if (validation.validateNotEmpty(firstName) == false) {
        return {
            status: 422,
            body: {
                message: 'First Name is required.'
            }
        };
    }
    if (validation.validateDisplayName(lastName) == false) {
        return {
            status: 422,
            body: {
                message: 'Last Name is required.'
            }
        };
    }

    //check if user already exists.
    const userAlreadyExists = await db.oneOrNone('SELECT email from users WHERE email=$1 LIMIT 1', [
        email
    ]);
    console.log(' result: '   userAlreadyExists);
    if (userAlreadyExists) {
        return {
            status: 409,
            body: {
                message: 'User with that email already exists'
            }
        };
    }

    try {
        // insert New user into DB
        await db.none(
            'INSERT INTO users (first_name, last_name, email, user_password, user_role, email_verification_token) VALUES ($1, $2, $3, $4, $5, $6)',
            [firstName, lastName, email, bcryptPassword, userRole, emailToken]
        );

        return {
            status: 201,
            body: {
                message: 'User created successfully'
            }
        };
    } catch (error) {
        return {
            status: 417,
            body: {
                message: error.toString()
            }
        };
    }
}

uj5u.com熱心網友回復：

您的問題是您使用的資料庫是通過回呼系統實作的function query(queryString, callback)，您await不需要等待它，return回呼中的實際上也不是端點的回傳。

最好的辦法是檢查您的資料庫庫是否具有異步方法，您可以在其中執行類似或類似的操作：

const { errror, result } = await db.query(....)

這樣，應用程式實際上將等待查詢完成。
