python爬虫使用urllib的post请求注意事项

import urllib.request
import urllib.parse
import json

url = 'https://fanyi.xx.com/sug'
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36'
}
data = {
    'kw': 'file'
}
data = urllib.parse.urlencode(data).encode('utf-8')
request = urllib.request.Request(url=url, data=data, headers=headers)
response = urllib.request.urlopen(request)
content = response.read().decode('utf-8')

str_data = json.loads(content)
print(str_data)

将data你要传送的kv编码为utf-8
