如何在thinkphp5.1中写接口及接口调用

在thinkphp5.1中如何写接口及如何调用接口

对于php不熟悉的人来说，解除thinkphp还是挺有难度的。

下面记录如何编写接口。

及如何对编写的接口进行调用。

1.首先在thinkphp中的application中的api/controller下新建文件Ecodemo.php

<?php // +---------------------------------------------------------------------- // | // +---------------------------------------------------------------------- // | // +---------------------------------------------------------------------- // | // +---------------------------------------------------------------------- namespace app\api\controller; use controller\BasicApi; use service\DataService; use service\NodeService; use service\ToolsService; use think\Db; use think\exception\HttpResponseException; /**  * 兼容适配接口  * Class Member  * @package app\api\controller  */ class Ecodemo extends BasicApi {     protected $table = 'Compatible';     /**      * 初始化      * @access protected      */     protected function initialize() {         parent::initialize();     }     /**      * 获取适配信息      * @access public      * @throws \think\Exception      * @throws \think\exception\PDOException      */     public function index() {         $param = $this->request->param();  //获取请求的参数         if (empty($_SERVER['HTTP_AUTHORIZATION']))             throw new HttpResponseException(json(['code' => 0, 'msg' => 'error！']));         $sign = $_SERVER['HTTP_AUTHORIZATION'];         $company = Db::name('authentication')->where('token', $sign)->value('company');         if (empty($company))             throw new HttpResponseException(json(['code' => 0, 'msg' => 'error！']));         $db = Db::name($this->table)             ->order(['sort' => 'asc', 'id' => 'desc'])             ->where('is_deleted', 0)             ->where('id', $param['list_id'])->field(['name','update_time','desc']);  //数据库查询         // dump($db);         return parent::_list($db);         // throw new HttpResponseException(json(['code' => 1, 'list' => $db]));     }     /**      * 修改适配信息      * @access public      * @throws \think\Exception      * @throws \think\exception\PDOException      */     public function update() {         $param = $this->request->param();         if (empty($_SERVER['HTTP_AUTHORIZATION']))             throw new HttpResponseException(json(['code' => 0, 'msg' => 'error！']));         $sign = $_SERVER['HTTP_AUTHORIZATION'];         $company = Db::name('authentication')->where('token', $sign)->value('company');         if (empty($company))             throw new HttpResponseException(json(['code' => 1, 'msg' => 'error！']));         if ($this->request->isPost()) {             Db::name($this->table)             ->where('id',$param['list_id'])             ->data(['name' => $param['content']])             ->update();   //数据库修改             throw new HttpResponseException(json(['code' => 0, 'msg' => '修改成功']));                       } else {             throw new HttpResponseException(json(['code' => 1, 'msg' => 'error！']));         }     }      /**      * 获取请求header      *      */     function getallheaders($param = null) {         $headers = array();         foreach ($_SERVER as $name => $value) {             if (substr($name, 0, 5) == 'HTTP_') {                 $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;             }         }         if($param != null){             return $headers[$param];         }         return $headers;     } }

2.通过接口进行访问

get请求，访问index接口

通过get请求问/application/api/controller/ecodemo.php中的index方法如下图所示 

post请求，访问update接口

将下图的json内的内容对数据库内容进行更改。

 最后我发现无论是get、post、put请求，我们都可以通过$this->request->param();方法获取到参数信息。
