python中的post请求解读

import requests

url = 'https://www.xxxxxx.com/'
# 需要注意的是Content-Length参数如果没有，data表单则不会随着请求被发送给服务端，且使用fiddler抓包的过程中，也无法看到data表单
headers = {
    'Content-Type': 'application/x-www-form-urlencoded',
    'Content-Length':'<calculated when request is sent>'
}
data = {'a': 1, 'b': 2,'c':'测试'}
result = requests.post(url, headers=headers, data=data)
print(result.content.decode('utf-8'))
