最初在Body和SourceFile間選擇body,上傳上去圖片不顯示，然後在相對路徑圖片和網路圖片都提示找不到檔案，body選擇絕對路徑可以上傳成功，SourceFile直接接$file

/*
 * 單圖上傳
 */
public function uploadpic()
{
    $ObsClient=new ObsClient();
    // 獲取表單上傳檔案
    $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'=>$resp['ObjectURL'],'msg'=>'上傳成功']);
    }else{
        return json_encode(['code'=>-1,'data'=>$resp['ObjectURL'],'msg'=>'上傳失敗']);
    }
}
