        sk = current_app.config.get("QINIU_SK")
        self.q = Auth(ak,sk)
        self.bucket_name = current_app.config.get("QINIU_BUCKET_NAME")
    def upload(self,loacfilepath,newfilename):
        token = self.q.upload_token(self.bucket_name,newfilename,3600)
        print(token)
        res = put_file(token,newfilename,loacfilepath,version="v2")
        print(res)
        if res[0]["key"] == newfilename:
            return newfilename
        else:
            return False
if __name__ == '__main__':
    from app import app
    with app.app_context():
        QiniuTool().upload("./../static/exo.jpg","static/img/exo.jpg")
