opener.addheaders=[headers]
urllib.request.install_opener(opener)#以上是伪装成网页

'#文章的爬取的正则表达式
result=re.compile(pat).findall(data)
result_1=re.compile(pat_1).findall(data)
q=0
for i in result_1:
    data_1=urllib.request.urlopen(i).read().decode('utf-8','ignore')
    result_2=re.compile(pat_2).findall(data_1)
    file="C:/Users/F.S.Z/Desktop/新建文件夹"+"/"+result[q]+".doc"
    with open(file,'w') as f:
        result_2[0]=result_2[0].replace('
','\r\n')
        result_2[0] = result_2[0].replace('
', ' ')
        f.write(result_2[0])
    print(result[q]+" success!!!")
    time.sleep(3)
    q+=1

运行结果
