将两个请求封装在一个方法里
retry(stop_max_attempt_number5, retry_on_resultlambda re_data: re_data is None, wait_fixed2000)def request(self, method, url, is_http2False, paramsNone, dataNone, jsonNone, headersNone, filesNone,verifyFalse, certNone, timeoutNone, proxiesNone, contentNone, cookiesNone, extensionsNone,**kwargs):try:if is_http2:re_data self.httpx_request(methodmethod.upper(), urlurl, is_http2is_http2, contentcontent,datadata, filesfiles, jsonjson, paramsparams, headersheaders,cookiescookies, timeouttimeout, extensionsextensions, **kwargs)else:re_data self.requests_request(methodmethod, urlurl, paramsparams, datadata, jsonjson,headersheaders, filesfiles, certcert, timeouttimeout, verifyverify,proxiesproxies, **kwargs)# 异常处理 报错显示具体信息except Exception as e:re_data None# 打印异常print(请求失败{0}.format(e))logger.error(Error occurred: %s, str(e), exc_infoTrue)# 重新抛出异常触发 retry 机制raise e# 返回响应结果return re_data
通过is_http2来区分
