接着上一个笔记编写第一个后台接口
新建数据表
- 在数据库zero中新建一个数据表,命名为db_account
- 编辑列。共有三列,id,name,password。并将id设为自增长和主键
编写后台接口
在控制器Controller目录中新建名为_A_mysql的php文件,此文件的功能是php操作mysql的常用代码,这里封装成一个文件,为了减少代码的重复,和方便修改mysql的登入信息。
_A_mysql.php代码如下
<?php
$con = mysql_connect("localhost","root","xiao1234");
if (!$con){die('Could not connect:'.mysql_error());}
mysql_select_db("zero",$con);
?>
AccountController.class.php代码如下
<?php
namespace Home\Controller;
use Think\Controller;
header("Content-Type: text/html;charset=utf-8");
header('Access-Control-Allow-Origin:*');//允许跨域
class AccountController extends Controller {
public function login(){
$name = $_GET['name']; // 获取参数
$password = $_GET['password']; // 获取参数
$data = $this -> mysql_select($name);
if(!$data['password'] || $data['password'] !== $password){
$re->state = 0;
}else{
$re->state = 1;
$re->data->id = $data['id'];
}
$this->ajaxReturn($re);
}
public function addAccount(){
$name = $_GET['name']; // 获取参数
$password = $_GET['password']; // 获取参数
$result = $this -> mysql_insert($name,$password);
$this->ajaxReturn($result);
}
public function deleteAccount(){
$name = $_GET['name']; // 获取参数
$result = $this -> mysql_delete($name);
$this->ajaxReturn($result);
}
public function setPassword(){
$name = $_GET['name']; // 获取参数
$password = $_GET['password']; // 获取参数
$result = $this -> mysql_updata($name,$password);
$this->ajaxReturn($result);
}
public function mysql_insert($name,$password){
if(json_encode($this->mysql_select($name))=='false'){//是否重名
include '_A_mysql.php';
mysql_query("INSERT INTO db_account (name, password)
VALUES ('{$name}', '{$password}')");
mysql_close($con);
$re = 1;
}else{
$re = 0;
}
return $re;
}
public function mysql_delete($name){
include '_A_mysql.php';
mysql_query("DELETE FROM db_account WHERE name='{$name}'");
mysql_close($con);
return;
}
public function mysql_updata($name,$password){
include '_A_mysql.php';
mysql_query("UPDATE db_account SET password = '{$password}'
WHERE name = '{$name}' ");
mysql_close($con);
return;
}
public function mysql_select($name){
include '_A_mysql.php';
$sql = "SELECT * FROM db_account WHERE name='{$name}'";
$result = mysql_query($sql);
$row = mysql_fetch_array($result);//获取一行数据
mysql_close($con);
return $row;
}
}
访问接口
在浏览器中输入
网页访问接口http://localhost/zero/index.php/Home/Account/addAccount?name=adrian&password=angel
在打开mysql管理工具,可以看到已经多了一条数据
插入数据ajax请求
打开包含有jqery.js的html页面的控制台
输入如下js代码
$.ajax({
type: "GET",
url: "http://localhost/zero/index.php/Home/Account/addAccount?",
data: {
name:'simon',
password:'simon',
},
dataType: "json",
success: function(result){
console.log('成功回调',result);
},
error: function(result){
console.log('失败回调',result);
}
});
