Flask中request获取请求参数再次拼接时，提示在请求上下文之外工作，请帮忙看看？

Question

请路过大佬帮忙看看。

背景：我需要请求leancloud的数据库，前端上每次会分页请求，因此URL上有参数；直接前端请求，会带上数据库的id和key，我不想泄漏。

我想在前端请求云函数里的api接口，api中识别前端带上的参数，拼接成一个新的URL，由服务端去请求leancloud。初学前端知识，请不吝赐教。源代码如下：

@app.route('/bbtalk', methods=['GET','POST'])
def get_data():
    # 看这里, request这个是线程级http请求全局变量, 在Flask收到请求时, 会设置当前HTTP请求的参数
    # 如果要在非HTTP请求外使用, 必需使用 `with app.test_request_context()` 包裹函数调用
    skip = request.args.get('skip')
    limit = request.args.get('limit')
    count = request.args.get('count')
    
if __name__ == '__main__':
#    app.run(port=5000,debug=True)
    # 改这儿
    with app.test_request_context(path='/请求路径', query_string='a=b&c=d'):
        print(get_data())
