PHP灌水机器人实现原理

实现原理：
通过curl工具模拟登录，然后调用相关接口发送数据进行各种操作。

需要掌握知识点：

• curl的POST/GET操作
• curl发送header头信息
• curl接受保存来自服务端的cookie
• curl发送cookie

代码示范

1. curl的GET操作

   private function projectCollections(): array{    $ts = microtime(true) * 1000;    $api = "http://www.****.com/json/projectCollections?status=1&username={$this->userName}&limit=1&projectID={$this->projectID}&ts=" . $ts;   //API地址    $curl = curl_init();    curl_setopt($curl, CURLOPT_URL, $api);    curl_setopt($curl, CURLOPT_HEADER, 0);//是否显示头信息    curl_setopt($curl, CURLOPT_COOKIEJAR, $this->cookie); //设置Cookie信息保存在指定的文件中    curl_setopt($curl, CURLOPT_COOKIEFILE, $this->cookie); //发送cookie信息    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);    curl_setopt($curl, CURLOPT_REFERER, "http://www.***.com/details/v5?id={$this->projectID}&isView=true");    curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.70 Safari/537.36");    $json = curl_exec($curl);    curl_close($curl);    \Log::error(var_export($json, true));    return json_decode($json, true);    //{"meta":{"total":"0","start":"1","size":"0"},"data":[]}}

2. curl的POST操作

//收藏    private function addCollection()    {        $api = "http://www.****.com/sjc/api/project/collection/add";        $postData = [            'id' => (string)$this->projectID,        ];        $data = json_encode($postData);        $length = strlen($data);        $headers = [            //'Origin:http://www.ilab-x.com',            //'Host:www.ilab-x.com',            "Content-type: application/json",            'Content-Length: ' . $length,        ];        \Log::error(var_export($postData, true));        \Log::error(var_export($data, true));        $curl = curl_init();        curl_setopt($curl, CURLOPT_URL, $api);        curl_setopt($curl, CURLOPT_HEADER, 0);//是否显示头信息        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);        curl_setopt($curl, CURLOPT_COOKIEJAR, $this->cookie); //设置Cookie信息保存在指定的文件中        curl_setopt($curl, CURLOPT_COOKIEFILE, $this->cookie); //发送cookie信息        curl_setopt($curl, CURLOPT_POST, 1);//post方式提交        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);//注意，这里提交json格式        curl_setopt($curl, CURLOPT_REFERER, "http://www.****.com/details/v5?id={$this->projectID}&isView=true");        curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.70 Safari/537.36");        curl_setopt($curl, CURLOPT_ENCODING, 'deflate');        $json = curl_exec($curl);        curl_close($curl);        \Log::error(var_export($headers, true));        \Log::error(var_export($json, true));        return json_decode($json, true);    }
