最初在Body和SourceFile间选择body,上传上去图片不显示，然后在相对路径图片和网络图片都提示找不到文件，body选择绝对路径可以上传成功，SourceFile直接接$file

/*
 * 单图上传
 */
public function uploadpic()
{
    $ObsClient=new ObsClient();
    // 获取表单上传文件
    $file = request()->file('image');
    $filename=$file->getOriginalName();
    $filetype= substr(strrchr($filename, '.'), 1);
    $filenametmp=time().rand(1000,9999).'.'.$filetype;
    try{
        $resp = $ObsClient -> putObject([
            'Bucket' => 'asdfdgffgdf',
            'Key' => $filenametmp,
            'SourceFile' =>$file,
        ]);
    }catch (Obs\Common\ObsException $obsException){
        printf("ExceptionCode:%s\n", $obsException->getExceptionCode());
        printf("ExceptionMessage:%s\n", $obsException->getExceptionMessage());
    }
    if($resp['HttpStatusCode']==200){
        return json_encode(['code'=>1,'data'=>$resp['ObjectURL'],'msg'=>'上传成功']);
    }else{
        return json_encode(['code'=>-1,'data'=>$resp['ObjectURL'],'msg'=>'上传失败']);
    }
}
