[PHP知识库]tp5 实现curl上传文件到另一个服务器

1.接收前端传过来的文件接口

   public function index()
    {

        $upload_path = DS . 'uploads' . DS .'image'.DS.date('Ymd', time()).DS;
        $public_path =  'public' . $upload_path;
        $type = $_FILES['file']['type'];
        $file_name = $_FILES['file']['name'];
        $tmp_name = $_FILES['file']['tmp_name'];
        $new_file_url=ROOT_PATH.$public_path;
        $new_file = ROOT_PATH.$public_path.$file_name;
        if(!file_exists($new_file_url)){
            mkdir($new_file_url,0777,true);
        }
        /*移动到临时文件*/
        move_uploaded_file($tmp_name,$new_file);
        $data = [
            'file' => new \CURLFile(realpath($new_file)),//'@'.realpath($tmp_name)
            'fileName'=>$file_name
        ];
        $data['file']->name= iconv('utf-8', 'gbk', $data['file']->name); //处理中文名文件
        $url='http://localhost/public/index.php/index/index/addFaImg'; //要发送到的url地址
        $res = $this->post($url,$data); //post提交数据
        if($res){
            $data = json_decode($res,true);
           return json($data);
        }

    }
    function post($url , $data=array()){

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
// POST数据
        curl_setopt($ch, CURLOPT_POST, 1);
// 把post的变量加上
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

        $output = curl_exec($ch);
        $curlErrNo = curl_errno($ch);
        $curlErr = curl_error($ch);
        curl_close($ch);
        return $output;
    }

2.另一个服务器接收curl传送的文件

   <?php


namespace app\index\controller;
use app\common\facade\Upload;
class index
{
    public function addFaImg()
    {
        // 获取curl传过来的文件
        $file = request()->file('file');
        $path='uploads/fa_image/';
        $res =Upload::upload($file,$path);
        return ['code' => 20000 , 'msg' => '上传成功','data' => $res];
    }
}

3.自己封装的上传文件的代码-------在application\common\facade里

<?php


namespace app\common\facade;


class Upload
{
    public static function upload($file, $path, $data = null)
    {
        // 获取表单上传文件 例如上传了001.jpg
        // 移动到框架应用根目录/uploads/ 目录下
        $up_dir = $path.date('Ymd', time()) . "/";  //创建目录
        if(!file_exists($up_dir)){
            mkdir($up_dir,0777,true);
        }
        $info = $file->validate(['ext'=>'webp,jpg,png,gif,jpeg,mp4,AVI,MOV'])->rule('md5')->move($up_dir);
        if($info){
            // 成功上传后 获取上传信息
            $res =  $info->getSaveName();
            // 输出 42a79759f284b767dfcb2a0197904287.jpg
            return str_replace("\\",'/',$up_dir.$res); //将反斜杆转为正斜杠 ;
        }else{
            // 上传失败获取错误信息
            $res = $file->getError();
            return $res;
        }
    }
}
