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 appapicontroller;
use thinkController;
use thinkDb;
use OSSOssClient;
use OSSCoreOssException;
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);
            $imgData = str_replace('
','',$imgData);
            $imgData = str_replace('
','',$imgData);
            $imgData = str_replace('	','',$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
