python request 모듈

*requests 패키지 설치 
pycharm에서 file -> settings -> Project interpreter -> requests 패키지 검색 및 설치 
(urllib3, requests, idna, chardet, certifi 가 설치됨) 

*requests import 

import requests 

*requests 메소드 사용법 

 -http://docs.python-requests.org/en/master/user/quickstart/ 
 
r=requests.get('https://api.github.com/events') 
 - GET 메소드 
 
r=requests.post('http://httpbin.org/post', data = {'key':'value'}) 
 - POST 메소드 
 
r=requests.put('http://httpbin.org/delete',data = {'key':'value'}) 

*requests payload 사용법 

payload = {'key':'value', 'key2':['value2', 'value3']} 
 - key에 value값이 여러개면 리스트로 작성 
r=requests.get('http://httpbin.org/get', params=payload) 
 

*requests response 

r.headers 
r.headers.get('content-type') 
r.text 
 -body 
r.content 
r.json() 
r.raw 
 - raw response content 

*custom headers 

url = 'https://api.github.com/some/endpoint' 
headers={'user-agent': 'my-app/0.0.1'} 
r=requests.get(url, headers=headers) 

*json 포맷 

url = 'https://api.github.com/some/endpoint' 
payload = {'some': 'data'} 
r = requests.post(url, json=payload) 

*post multipart-encoded file(업로드) 

url = 'http://httpbin.org/post' 
files = {'file': open('report.xls', 'rb')} 
files = {'file': ('report.csv', 'some,data,to,send\nanother,row,to,send\n')} 
 - file 내용을 지정 
r = requests.post(url, files=files) 
r.text 

*response status codes 

r.status_code 
r.status_code == 200 
 - 200이면 True 반환 

*cookies (원세션이 아닌 세션 유지방법) 

url='http://httpbin.org/events' 
data={'username':'admin','password':'password'} 
proxies='http://localhost:8080' 
 -프록시 설정 
s=requests.session() 
req=request.Reuest('POST', url, data=data) 
 -요청값을 req에 저장 
prepared=s.prepare_request(req) 
 -prepared에 쿠키값이 저장됨 
resp=s.send(prepared, proxies=proxies) 

*프록시 설정 

proxies = {'http': 'http://10.10.1.10:8080','https': 'http://10.10.1.10:8080'} 
requests.get('http://example.org', proxies=proxies) 

*기본 설정방식 

import requests 
 
s = requests.session() 
login_url = 'http://192.168.10.134/dvwa/login.php' 
login_data = {'username':'admin', 'password':'password', 'Login':'Login'} 
proxies = {'http':'http://localhost:9000', 'https':'http://localhost:9000'} 
req = requests.Request('POST', login_url, data=login_data) 
prepared = s.prepare_request(req) 
resp = s.send(prepared, proxies = proxies)
