这篇文章主要介绍了python用requests实现http请求过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

1. get

import requests# 最简单的get请求r = requests.get(url)print(r.status_code)print(r.json())# url 中?key=value&key=valuer = requests.get(url, params=params)# form 表单params = {"username":"name", "password":"passw0rd"}headers = {'Content-Type':'application/x-www-form-urlencoded'}r = requests.get(url, params=params, headers=headers)# 下载r = requests.get(url)r.raise_for_status()with open(target, 'wb') as f: for ch in r.iter_content(10000): result_file_size += f.write(ch)

2. post请求

data = {'name':'train', 'device':'CN0989'}r = requests.post(url, json=data)#上传files = { "file": (os.path.basename(filepath), open(filepath, "rb"), "application/zip")}print('POST %s'%url)with open(filepath, 'rb') as f: r = requests.post(url, files=files)

3. 登录

_session = requests.Session()# loginurl = '%s/login'%_basic_urlparams = {"username":"admin", "password":"admin"}headers = {'Content-Type':'application/x-www-form-urlencoded'}r = _session.post(url, params=params, headers=headers)#做其他请求r = _session.get(url)_session.close()
