通過requests.session().request 封裝request方法
考慮到請求HTTP/2.0
同時封裝httpx 來處理HTTP/2.0的請求

封裝requests

封裝httpx

@retry(stop_max_attempt_number=5, retry_on_result=lambda re_data: re_data is None, wait_fixed=2000)def httpx_request(self, method, url, is_http2=False, content=None, data=None, files=None, json=None, params=None,headers=None, cookies=None, timeout=None, extensions=None, proxy=None, **kwargs):# 對異常進行捕獲try:"""使用client  method.upper() 請求方法都轉(zhuǎn)為大寫"""# 處理代理proxies = Noneif proxy:proxies = {'http://': 'http://' + proxy,'https://': 'https://' + proxy,}re_data = httpx.Client(http2=is_http2, proxies=proxies).request(method.upper(), url, content=content,data=data, files=files, json=json,params=params, headers=headers,cookies=cookies, timeout=timeout,extensions=extensions, **kwargs)# 異常處理 報錯顯示具體信息except Exception as e:re_data = None# 打印異常print("請求失敗：{0}".format(e))logger.error("Error occurred: %s", str(e), exc_info=True)# 重新拋出異常，觸發(fā) retry 機制raise e# 返回響應結(jié)果return re_data

將兩個請求封裝在一個方法里

@retry(stop_max_attempt_number=5, retry_on_result=lambda re_data: re_data is None, wait_fixed=2000)def request(self, method, url, is_http2=False, params=None, data=None, json=None, headers=None, files=None,verify=False, cert=None, timeout=None, proxies=None, content=None, cookies=None, extensions=None,**kwargs):try:if is_http2:re_data = self.httpx_request(method=method.upper(), url=url, is_http2=is_http2, content=content,data=data, files=files, json=json, params=params, headers=headers,cookies=cookies, timeout=timeout, extensions=extensions, **kwargs)else:re_data = self.requests_request(method=method, url=url, params=params, data=data, json=json,headers=headers, files=files, cert=cert, timeout=timeout, verify=verify,proxies=proxies, **kwargs)# 異常處理 報錯顯示具體信息except Exception as e:re_data = None# 打印異常print("請求失敗：{0}".format(e))logger.error("Error occurred: %s", str(e), exc_info=True)# 重新拋出異常，觸發(fā) retry 機制raise e# 返回響應結(jié)果return re_data

通過is_http2來區(qū)分

測試代碼如下
