Question

我正在尝试将我的后端数据库mysql连接到我的应用程序，但由于我不了解php而无法做到并得到。我希望在登录时从数据库中检查我的用户名和密码，我自己尝试过但无法获得，请发布带有很少解释的解决方案

import { Component, OnInit } from '@angular/core';
 import { Router } from '@angular/router';
 import { FormBuilder, FormGroup } from '@angular/forms';


 @Component({
   selector: 'login-form',
   templateUrl: './login-form.component.html',
   styleUrls: ['./login-form.component.css']
 })
 export class LoginFormComponent implements OnInit {
    username: string;
    password: string;
    form: FormGroup;
   constructor(private router: Router, private formBuilder: FormBuilder) {
   }

   ngOnInit() {
     this.initf();

   }
   initf() {
     this.form = this.formBuilder.group({
       username: this.username,
       password: this.password
     });
   }
   log() {
 console.log(this.username, this.password);
 if ( this.username === 'admin' && this.password === 'admin') {

       this.router.navigate(['todoapp']);
     }


   }
   }

<?php 


 header('Access-Control-Allow-Origin: *');
 header('Content-Type: application/json');

 if(!isset($_POST)) die();

 session_start();

 $response = [];

 $con = mysqli_connect('localhost', 'root', '', 'test_site');

 $username = mysqli_real_escape_string($con, $_POST['username']);
 $password = mysqli_real_escape_string($con, $_POST['password']);

 $query = "SELECT * FROM `users` WHERE username='$username' AND password='$password'";

 $result = mysqli_query($con, $query);

 echo json_encode($response);

我的朋友，解释的时间更长了一点，但是我可以告诉你，您可以按照本教程的有关如何将PHP和angular进行连接

至此，您的后端已在PHP中 https://www.techiediaries.com/php-angular/

，但是您需要遵循第二步，以了解如何使用PHP构建，结构化Angular组件和服务 https://www.techiediaries.com/php-angular-crud-api-httpclient-forms/

希望这会有所帮助
