string =string.encode('gbk') str = urllib.parse.quote(string ) print(str) 1. 2. 3. 4. 5. 运行,得到如下结果: %CB%D5%D6%DD 1. 结果终于正确了。接下来再反向有url编码转中文 3、url编码转中文字符串—转换失败 import urllib string = '%CB%D5%D6%DD' str = urllib.parse.unquote(string)...

2.使用Request发送GET请求 HTTP中最常见的请求之一就是GET 请求,下面首先来详细了解一下利用requests构建GET请求的方法。 GET 参数说明:get(url, params=None, **kwargs): ❖ URL: 待请求的网址 ❖ params :(可选)字典,列表为请求的查询字符串发送的元组或字节 ...
二、Url编码 1、urlencode( ) from urllib import parse from urllib import request url = 'http://www.baidu.com/s?' dict1 ={'wd': '百度翻译'} url_data = parse.urlencode(dict1) #unlencode()将字典{k1:v1,k2:v2}转化为k1=v1&k2=v2 ...
print(unencode_url)输出结果为:https%3A//www.runoob.com/ https://www.runoob.com/模拟头部信息 我们抓取网页一般需要对 headers(网页头信息)进行模拟,这时候需要使用到 urllib.request.Request 类:class urllib.request.Request(url, data=None, headers={}, origin_req_host=None, unverifiable=False, method...
