A simple small example of API interface development - based on thinkphp6.x

Mainly helpful for PHP children who have never been exposed to interface development. That is: the front end submits a product ID and returns product details; there is no authentication or anything else, it is just used to understand the process and become proficient from getting started

A simple small example of API interface development - based on thinkphp6.x, the code is as follows:

Step 1: Front-end code (requester) view/index/index.html:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>API接口开发简单小实例-基于thinkphp6.x</title>
</head>
<body>
<form action="http://localhost/index.php/index/index/api_chaxun/" method="post">
    <input type="text" name="goods_id">
    <input type="submit" value="提交查询">
</form>
</body>
</html>

Step 2: Controller code (requester) controller/index.php:

<?php 
namespace app\controller;
use app\BaseController;
class Index extends BaseController {
        //前端视图
public function index() {
return view();
}
//提交查询入口
public function api_chaxun() {
// http协议请求
$url = &#39;http://localhost/index.php/index/goods/api/&#39;;
// input(&#39;goods_id&#39;) 是前端的from传过来的name值
$ch = curl_init($url.&#39;?goods_id=&#39;.input(&#39;goods_id&#39;));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// 执行 并把执行后的数据赋值给 $data
$data = curl_exec($ch);
// 关闭
curl_close($ch);
// 返回数据
return $data;
}
}

Step 3: API interface, code controller/goods.php:

<?php 
namespace app\controller;
use app\BaseController;
use think\facade\Db;
class Goods extends BaseController {
/** 客户端提交商品ID（goods_id）给API
* API返回此商品信息
**/
public function api($goods_id=1) {
// 查询 并把数据赋值给 $data
$data = Db::name(&#39;goods&#39;)->where(&#39;id&#39;,$goods_id)->find();
// 返回数据
return json($data);//print_r($data);
}
}
