request.Request类

如果想要在请求的时候增加一些请求头，用request.Request

from urllib import request
headers = {
	'userAgent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36'
}
req = request.Request("http://www.baidu.com/",headers = headers)
resp = request.urlopen(req)
print(resp.read()[:10])
#返回结果如下
b'<!DOCTYPE '

    'Referer':'https://www.lagou.com/jobs/list_python?labelWords=&fromSearch=true&suginput=',
}
url = 'https://www.lagou.com/jobs/list_python?labelWords=&fromSearch=true&suginput='
data = {
    'first':'true',
    'pn':1,
    'kd':'python'
}
req = request.Request(url,headers=headers,data=parse.urlencode(data).encode('utf-8'),method='POST')
resp = request.urlopen(req)
print(resp.read().decode('utf-8'))
