實戰(zhàn)代碼?

import requestsif __name__ == '__main__':http_headers = {'Accept': '*/*','Connection': 'keep-alive','User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.116 Safari/537.36'}try:resp = requests.get(url=item, headers=http_headers,timeout=10)except Exception as e:continueprint("resp", resp.url)

以上代碼未有重試機(jī)制，下面加上重試機(jī)制加以完善

def get_real_url(url,try_count = 1): if try_count > 3:return url try:rs = requests.get(url,headers=http_headers,timeout=10)if rs.status_code > 400:return get_real_url(url,try_count+1)return rs.url except:return get_real_url(url, try_count + 1)
