请求与响应

请求方式

import requests

# GET
r = requests.get('url')

# POST
r = requests.post('url')

# PUT
r = requests.put('url')

# delete
r = requests.delete('url')

# head
r = requests.head('url')

# options
r = requests.options('url')

数据交互

ajax传参

import requests

data = {'key':'value'}

r = requests.post('url',data=data)

url传参

import requests

payload = {'key1': 'value1', 'key2': 'value2'}

r = requests.get(‘url, params=payload)

# print url
>>> print(r.url)
url?key2=value2&key1=value1

文件交互

import requests

r = requests.get('https://github.com/favicon.ico')
with open('favicon.ico','wb') as f:
  f.write(r.content)

响应

import requests

# GET
r = requests.get('url')

# 响应码
print(r.status_code)

# 以文本格式返回响应内容
print(r.text)

# 以字节格式返回响应内容
print(r.content)

# 以json格式返回相应内容，因为就算请求出错也会返回一串json格式的字符串。
# 所以可以使用r.status_code或者r.raise_for_status来判断响应是否成功
print(r.json())

import requests

headers={
    'content-encoding': 'gzip',
    'transfer-encoding': 'chunked',

s.auth = ('username','password')
s.headers.update({'x-test':'true'})

r = s.get('url')

Prepared Request

from requests import Request, Session

data = {
  
}
headers = {
  
}

s = Session()

req = requests.post('url',data=data,headers=headers)

# 将请求表示为数据结构
prepped = s.prepare_request(req)
r = s.send(prepped)
print(r.text)

身份验证

import requests
form requests.auth import HTTPBasicAuth

r = requests.post('url',auth=HTTPBasicAuth('username','password'))
