ThinkPHP5使用阿里云OSS图片上传

1、下载OSS文件放在网站根目录下（OSS文件下载地址：https://gitee.com/jth1234/oss_files.git）

2、在入口文件中加载OSS

3、config文件配置oss信息（ossKeyId、ossKeySecret、endpoint以上信息开通阿里云oss服务后可获得；bucket是创建的存储目录名）

4、上传base64图片（UploadController.php）

 <?php
 namespace app\api\controller;
 use think\Controller;
 use think\Db;
 use OSS\OssClient;
 use OSS\Core\OssException;
 class UploadController extends Controller {
     /**
      * 上传图片到oss
      * @param string $info  base64图片
      *
      */
     public function upload_pic(){
         $imgData = input('info','');
         if($imgData){
             $img_len = strlen($imgData);
             $imgData = str_replace('\n','',$imgData);
             $imgData = str_replace('\r','',$imgData);
             $imgData = str_replace('\t','',$imgData);
             $imgData = str_replace(PHP_EOL,'',$imgData);
             $imgData = str_replace('\\','',$imgData);
             $imgData = str_replace(' ','+',$imgData);
 
             $host = config('public.host');
 
             $date = date('Y-m-d');
             $dir = "./public/user/$date";
             if (!file_exists($dir)){
                 mkdir ($dir,0777,true);
             }
             $img = base64_decode($imgData);
             $uniqid_name = md5(uniqid(rand()));
             $tmpImg = './public/user/'.$date.'/user_'.$uniqid_name.'.jpg';
             $tmpImg1 = '/public/user/'.$date.'/user_'.$uniqid_name.'.jpg';
             $a = file_put_contents($tmpImg,$img);//保存图片，返回的是字节数
             if($a){

                 // <yourLocalFile>由本地文件路径加文件名包括后缀组成，例如/users/local/myfile.txt
                 $filePath = './public/user/'.$date.'/user_'.$uniqid_name.'.jpg';
                 try{
