Python爬蟲02 請求模組

七、json資料

response.text 返回unicode格式的資料(str)

response.content 返回位元組流資料(二進位制)

response.content.decode(『utf-8』) 手動進行解碼

response.url 返回url

response.encode() = 『編碼』

import requests

url=
''headers=
wd=res=requests.get(url,params=wd,headers=headers)
print
(res.url)
# 返回請求的url
# wd=%e4%b8%ad%e5%9b%bd

import requests

res=requests.get(
'')print
(res.text)
# 中文亂碼
print
(res.content.decode(
'utf-8'))
# 手動解碼

import requests

import json

key=

input
('請輸入：'
)data =

url需要去掉_o

url =

''headers =
res = requests.post(url,data=data,headers=headers)
res.encoding =
'utf-8'
html = res.text
# 或 html=res.content.decode('utf-8')

j_s=json.loads(html)

trans=j_s[
'translateresult'][
0][0
]['tgt'
]print
(trans)

import requests

proxy =
url =
''res = requests.get(url,proxies=proxy)
print
(res.text)

import requests

url =
''res = requests.get(url,verify=
false
)print
(res.text)

import requests

url=
''headers=
res=requests.get(url,headers=headers)
print
(res.text)

import requests

url =
''headers =
res = requests.get(url,headers=headers)
print
(res.content.decode(
'utf-8'
))

import requests

req=requests.session(
)headers=

def

login()
:# 拿到驗證碼
res=req.get(
'')    pic=res.content
with
open
('yzm.png'
,'wb'
)as f:
f.write(pic)
s=input
('請輸入驗證碼座標：'
)    data=
response=req.post(
'',data=data,headers=headers)
print
(response.text)
login(
)

import json

s='pyt'

r=json.dumps(s)

print
(r)# "pyt"

print

(json.loads(r)
)# pyt

json.dump(s,

open
('json.txt'
,'w'
)

print

(json.load(
open
('json.txt'
,'r'))
)
