一、伪装
把爬虫程序伪装成用浏览器来访问地址。
复制这一段"user-agent",伪装成浏览器的header。
import requests
url = "https://haokan.baidu.com/v?pd=wisenatural&vid=13010513670189503165"
headers = {
"User-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36"
}
rep = requests.get(url,headers=headers)
print(rep.text)
rep.close;
二、访问百度翻译
?由图可以看到该地址的请求方法为post,并且可以向该地址发送数据接收返回内容。
import requests
while(True):
url = "https://fanyi.baidu.com/sug"
s = input("请输入你要翻译的英文单词:")
kw = {
"kw":s
}
rep = requests.post(url, data= kw)
print(rep.json())
rep.close()
运行结果:
三、访问豆瓣排行榜
这回要用get函数了,如果嫌弃请求地址太长,可以用字典封装他的参数(右图所示)。这次还是要输入header因为豆瓣还是有一定的反爬能力🦎。
import requests
url = " https://movie.douban.com/j/chart/top_list"
#重新封装参数
dic = {
"type": "1",
"interval_id": "100:90",
"action":"",
" start":"0",
"limit": "20"
}
headers = {
"User-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36"
}
rep = requests.get(url=url, params=dic,headers=headers)
print(rep.text)
rep.close()
