方法封装：  

public function uploads(Request $request)
{
	$pictrue = ‘‘; // 获取图片转base64的字符串
	$result = [];
	// 转化base64编码图片 jpeg、jpg、png、bmp、gif
	if(preg_match(‘/^(data:s*image/(w+);base64,)/‘, $pictrue, $result)) {
		$type = $result[2]; // 获取图片类型
		if(in_array($type, array(‘pjpeg‘,‘jpeg‘,‘jpg‘,‘bmp‘,‘png‘))) {
			// 图片名字                
			$fileName = time().rand(1,1000).‘.‘.$type; // 图片名称
			// 临时文件
			$tmpfname = tempname("./image/", "FOO"); // windows
			$tmpfname = (‘/tmp/‘, ‘FOO‘); // linux
			// 保存图片
			$handle = fopen($tmpfname, "w");

			// return [$pic, $result];
			$object = ‘school/avatar/‘.date(‘Y/m/d‘).‘/‘.$fileName; // 阿里云上传地址
			if (fwrite($handle, base64_decode(str_replace($result[1], ‘‘, $pic)))) 
			{
				// 上传图片至阿里云OSS
				$ossClient = new Aliyunoss();
				$data = $ossClient->uploads($object, $tmpfname);
				// return [$pic, $result, $data];
				// 关闭缓存
				fclose($handle);
				// 删除本地该图片
				unlink($tmpfname);
				// 返回图片链接
				return StatusCode::getCode(0, [‘data‘ => $data]);
			}else {
				return response([‘message‘=>‘图片上传失败‘], 200);
			}

		}else {
			return response([‘message‘=>‘图片类型错误‘], 200);
		}                    
	} else {
		return response([‘message‘=>‘图片编码错误‘], 200);
