用python 寫了一個(gè) 爬取ip地址的爬蟲，由于該網(wǎng)站是反爬蟲的，所以寫了代理使用線程池開啟10個(gè)線程來(lái)爬取ip地址然而直接報(bào)錯(cuò)’list’ object has no attribute ’get’不知道如何解決，貼上本人代碼。from bs4 import BeautifulSoupimport requestsimport reimport timefrom multiprocessing import Poolimport pymysqlimport randomfrom threadpool import *

問(wèn)題解答

makeRequests是做什么的？你是不是把requests賦值成了list類型，下面再requests.get(*)自然就出錯(cuò)了吧。

makerequests類似python的map函數(shù)，里面有兩個(gè)參數(shù)（function，list（）），以list里面的參賽供給給前面的函數(shù)進(jìn)行運(yùn)作……里面的requests是requests模塊的方法，可能重名了吧，又或者url[0]這個(gè)寫法是錯(cuò)誤的，等下回去調(diào)試一下……

重名了，建議這一行

requests = makeRequests(download,proxy_url_list())[pool.putRequest(req) for req in requests]

先改成

myrequests = makeRequests(download,proxy_url_list())[pool.putRequest(req) for req in myrequests]

再試試
