}
# 查询字符串
params = {'name': 'Jack', 'age': '24'}
r = requests.get(url=url, headers=headers, params=params)
print r.status_code # 获取响应状态码
print r.content # 获取响应消息
if __name__ == "__main__":
pass
requests模块发送post请求
requests.post(url=url, headers=headers, data=params)
- url:请求url地址
- headers:请求头
- data:发送编码为表单形式的数据
# coding:utf-8
import requests
# 请求url
url = "http://httpbin.org/post"

}
# 查询字符串
params = {'name': 'Jack', 'age': '24'}
r = requests.post(url=url, headers=headers, data=params)
print r.status_code # 获取响应状态码
print r.content # 获取响应消息
if __name__ == "__main__":
pass
requests模块上传文件
requests.post(url=url, headers=headers, data=params, files=files)
参数说明:
- url:请求url地址
