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）
1 <?php 2 namespace app\api\controller; 3 use think\Controller; 4 use think\Db; 5 use OSS\OssClient; 6 use OSS\Core\OssException; 7 class UploadController extends Controller { 8 /** 9 * 上传图片到oss 10 * @param string $info base64图片 11 * 12 */ 13 public function upload_pic(){ 14 $imgData = input(\'info\',\'\'); 15 if($imgData){ 16 $img_len = strlen($imgData); 17 $imgData = str_replace(\'\n\',\'\',$imgData); 18 $imgData = str_replace(\'\r\',\'\',$imgData); 19 $imgData = str_replace(\'\t\',\'\',$imgData); 20 $imgData = str_replace(PHP_EOL,\'\',$imgData); 21 $imgData = str_replace(\'\\\',\'\',$imgData); 22 $imgData = str_replace(\' \',\'+\',$imgData); 23 24 $host = config(\'public.host\'); 25 26 $date = date(\'Y-m-d\'); 27 $dir = "./public/user/$date"; 28 if (!file_exists($dir)){ 29 mkdir ($dir,0777,true); 30 } 31 $img = base64_decode($imgData); 32 $uniqid_name = md5(uniqid(rand())); 33 $tmpImg = \'./public/user/\'.$date.\'/user_\'.$uniqid_name.\'.jpg\'; 34 $tmpImg1 = \'/public/user/\'.$date.\'/user_\'.$uniqid_name.\'.jpg\'; 35 $a = file_put_contents($tmpImg,$img);//保存图片，返回的是字节数 36 if($a){ 37 $accessKeyId = config(\'oss.ossKeyId\'); 38 $accessKeySecret = config(\'oss.ossKeySecret\'); 39 // Endpoint以杭州为例，其它Region请按实际情况填写。 40 $endpoint = config(\'oss.endpoint\'); 41 // 存储空间名称 42 $bucket= config(\'oss.bucket\'); 43 // 文件名称 44 $object = \'user/\'.$date.\'/user_\'.$uniqid_name.\'.jpg\'; 45 // <yourLocalFile>由本地文件路径加文件名包括后缀组成，例如/users/local/myfile.txt 46 $filePath = \'./public/user/\'.$date.\'/user_\'.$uniqid_name.\'.jpg\'; 47 try{ 48 $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint); 49 $ossClient->uploadFile($bucket, $object, $filePath); 50 unlink($filePath); 51 } catch(OssException $e) { 52 $data=array(\'code\'=>config(\'code.error\'),\'msg\'=>"上传失败"); 53 return json($data); 54 } 55 $img_src = config(\'oss.host\')."/".$object; 56 $data=array(\'code\'=>config(\'code.success\'),\'msg\'=>"上传成功",\'data\'=>$img_src); 57 return json($data); 58 }else{ 59 $data=array(\'code\'=>config(\'code.error\'),\'msg\'=>"上传失败"); 60 return json($data); 61 } 62 }else{ 63 $data=array(\'code\'=>config(\'code.error\'),\'msg\'=>"上传图片不能为空"); 64 return json($data); 65 } 66 } 67 /** 68 * 删除OSS上的图片 69 * @param string $info OSS上完整的图片地址 70 * 71 */ 72 public function pic_del(){ 73 $info = input(\'pic_addr\',\'\'); 74 if(!empty($info)){ 75 $ex = config(\'oss.host\').\'/\'; 76 $arr = explode($ex,$info); 77 $accessKeyId = config(\'oss.ossKeyId\'); 78 $accessKeySecret = config(\'oss.ossKeySecret\'); 79 $endpoint = config(\'oss.endpoint\'); 80 $bucket= config(\'oss.bucket\'); 81 $object = $arr[1]; 82 try{ 83 $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint); 84 $ossClient->deleteObject($bucket, $object); 85 } catch(OssException $e) { 86 printf(__FUNCTION__ .
