1  使用urlencode  多个参数请求使用 

# 使用urlencode  多个参数请求使用
# https://www.baidu.com/s?wd=周杰伦&sex=男  网页
import urllib.request
import urllib.parse

base_url = 'https://www.baidu.com/s?'

data = {
    'wd': '周杰伦',
    'sex': '男',
    'sing':'歌曲'
}

new_data = urllib.parse.urlencode(data)

url = base_url + new_data

headers = {"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.82 Safari/537.36 Edg/116.0.0.0"}

request = urllib.request.Request(url=url, headers=headers)
#
# 模拟服务器发送请求
response = urllib.request.urlopen(request)

# 读取html页面数据 获取相应源码
content = response.read().decode("utf8")
print(content)

2  百度翻译post请求    post无法添加路径 

request = urllib.request.Request(url=url, headers=headers, data=data)

# 百度翻译  post请求
# 引入
import urllib.request
# 路径 在浏览器 F12找到 对应自己需要的路径
url = 'https://fanyi.baidu.com/sug'
# 请求头
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.82 Safari/537.36 Edg/116.0.0.0"}
# data
data = {
    'kw': 'spider'
}
# 转换data数据  在转换成utf-8格式
data = urllib.parse.urlencode(data).encode('utf-8')
# 防止反爬 post无法拼接路径  所有只能在 requst中定义  定义数据
request = urllib.request.Request(url=url, headers=headers, data=data)

# 模拟服务器发送请求
response = urllib.request.urlopen(request)

# 读取html页面数据 获取相应源码
content = response.read().decode("utf-8")
# 引入
import json
# 字符串转换成json
obj = json.loads(content)

print(obj)

3  百度翻译全部数据获取

# 百度翻译全部数据
import urllib.request
import urllib.parse

# 找到全部数据的路径
url = 'https://fanyi.baidu.com/v2transapi?from=en&to=zh'
# 请求头  换成了cookie
