post请求

import urllib.request
import urllib.parse

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36 Edg/96.0.1054.62'
}
data = {
    'kw':'Spider'
}
reqData = urllib.parse.urlencode(data).encode('utf-8')
url = 'https://fanyi.baidu.com/sug'
request = urllib.request.Request(url=url,headers=headers,data=reqData)
response = urllib.request.urlopen(request)
content = response.read().decode('utf-8')
print(content)

import json
obj = json.loads(content)
print(obj)

　　data先urlencode之后还要再encode，保证请求参数是字节
