tornado利用装饰器记录每个http请求

python利用装饰器记录每个http请求

设置装饰器

from functools import wraps
from datetime import datetime

"""
@function 用于记录每个http请求
"""

def record_http_request(func):
    @wraps(func)
    def record(self, *args, **kwargs):
        request_time = str(datetime.now())
        response = func(self, *args, **kwargs)
        http_request = dict(
            request_time=request_time,
            expend_time=self.request.request_time(),
            response_time=str(datetime.now()),
            request_ip=self.request.remote_ip,
            method=self.request.method,
            url=self.request.uri,
            request_params=self.request.arguments,
            response_code=self.get_status(),
            response_text=self.response_value,
        )
        print(http_request)
        return response

    return record

然后在每个请求函数上面加上这个装饰器

from abc import ABC
from tornado.web import RequestHandler
from tornado.gen import coroutine
from handler.record_infomation import record_http_request

class Index(RequestHandler, ABC):
    @coroutine
    @record_http_request
    def get(self, *args, **kwargs):
        self.response_value = {"status": 200, "message": "dddd"}
        self.write(self.response_value)

这个时候我们那就可以看到装饰器中的print值为

{'request_time': '2019-04-06 19:16:54.951968', 'expend_time': 0.000576019287109375, 'response_time': '2019-04-06 19:16:54.952035', 'request_ip': '192.168.0.102', 'method': 'GET', 'url': '/', 'request_params': {}, 'response_code': 200, 'response_text': {'status': 200, 'message': 'dddd'}}

值已经拿到了，是存库还是记录到日志文件就随便了
