内网环境如何访问钉钉服务接口

环境描述

由于工作需要，业务项目需要部署在内网中，然后通过另一台可访问公网的服务器作为代理服务器，实现公网访问业务

问题描述

由于业务服务不能直接访问公网，关于钉钉业务代码无法执行

限制说明

业务服务器不能开通公网访问，只能访问代理服务器
原有代码不能过多改动，尽量少改

实现思路

在代理服务器构建服务接收钉钉服务接口请求，并转发至公网，钉钉服务接口成功响应后，数据再返回到业务服务器的响应中
使用sanic的中间件拦截所有请求以及对应的请求参数

代码展示

@app.middleware('request')
def handle_request(request):dingDingTalk = DingTalkClient(request)return json(status=200, body=dingDingTalk.get_result())@app.route('/<path>', methods=["GET", "POST"], strict_slashes=False)
async def path(request):return json(status=200, body={})@app.route('/<path>/<path2>', methods=["GET", "POST"], strict_slashes=False)
async def path2(request):return json(status=200, body={})@app.route('/<path>/<path2>/<path3>', methods=["GET", "POST"], strict_slashes=False)
async def path3(request):return json(status=200, body={})@app.route('/<path>/<path2>/<path3>/<path4>', methods=["GET", "POST"], strict_slashes=False)
async def path4(request):return json(status=200, body={})if __name__ == '__main__':app.run(host='0.0.0.0', port=800, debug=False)

说明： 由于本身框架本身会匹配路由, /<path 是为了让请求顺利抵达中间件
