python安装requests库的实例代码

pip install requests

import requests

 

response = requests.get('http://www.baidu.com')

print(response.status_code) # 打印状态码

print(response.url)     # 打印请求url

print(response.headers)   # 打印头信息

print(response.cookies)   # 打印cookie信息print(response.text) #以文本形式打印网页源码

print(response.content) #以字节流形式打印

import requests

 

requests.get('http://httpbin.org/get')

requests.post('http://httpbin.org/post')

requests.put('http://httpbin.org/put')

requests.delete('http://httpbin.org/delete')

requests.head('http://httpbin.org/get')

requests.options('http://httpbin.org/get')

import requests
response = requests.get('http://httpbin.org/get')print(response.text)

import requests

response = requests.get(http://httpbin.org/get"htmlcode">

import requests

response = requests.get('http://httpbin.org/get')

print(response.text)

print(response.json()) #response.json()方法同json.loads(response.text)

print(type(response.json()))


案例之一：


import requests
 
URL = 'http://ip.taobao.com/service/getIpInfo.php' # 淘宝IP地址库API
try:
  r = requests.get(URL, params={'ip': '8.8.8.8'}, timeout=1)
  r.raise_for_status()  # 如果响应状态码不是 200，就主动抛出异常
except requests.RequestException as e:
  print(e)
else:
  result = r.json()
  print(type(result), result, sep='\n')


使用 Requests 模块，上传文件也是如此简单的，文件的类型会自动进行处理：


import requests
 
url = 'http://127.0.0.1:5000/upload'
files = {'file': open('/home/lyb/sjzl.mpg', 'rb')}
#files = {'file': ('report.jpg', open('/home/lyb/sjzl.mpg', 'rb'))}   #显式的设置文件名
 
r = requests.post(url, files=files)
print(r.text)




import requests
 
url = 'http://127.0.0.1:5000/upload'
files = {'file': ('test.txt', b'Hello Requests.')}   #必需显式的设置文件名
 
r = requests.post(url, files=files)
print(r.text)
