一、HTTP,GET請(qǐng)求,無(wú)參

GET http://httpbin.org/get

Python3 http.client

import http.client

# 1. 建立HTTP連接
conn = http.client.HTTPConnection("httpbin.org")
# 2. 發(fā)送GET請(qǐng)求，制定接口路徑
conn.request("GET", '/get')
# 3. 獲取相應(yīng)
res = conn.getresponse()
# 4. 解析相應(yīng).進(jìn)行解碼
print(res.read().encode("utf-8")) # 自己解碼

Python3 urllib.request

import urllib

res = urllib.request.urlopen("http://httpbin.org/get")
print(res.read().decode("utf-8"))? # 自己解碼

Python3 requests

import requests

res = requests.get("http://httpbin.org/get")
print(res.text) # 自動(dòng)按默認(rèn)utf-8解碼

二、HTTPS,GET請(qǐng)求,帶中文參數(shù)

GET http://httpbin.org/get?name=張三&age=12

Python3 http.client

import http.client
import urllib.parse

conn = http.client.HTTPSConnection("httpbin.org")
url = urllib.parse.quote("/get?name=張三&age=12", safe=':/?=&') # 進(jìn)行url編碼
conn.request("GET", url)
res = conn.getresponse()
print(res.read().decode("utf-8")) # 自己解碼

Python3 urllib.request

import urllib
import urllib.parse

url = urllib.parse.quote("https://httpbin.org/get?name=張三&age=12", safe=':/?=&') # 進(jìn)行url編碼
res = urllib.request.urlopen("url")
print(res.read().decode("utf-8"))? # 自己解碼

Python3 requests

import requests

res = requests.get("https://httpbin.org/get?name=張三&age=12") # 自動(dòng)編碼
print(res.text) # 自動(dòng)按默認(rèn)utf-8解碼

三、Post x-www-form-urlencoded傳統(tǒng)表單請(qǐng)求

POST http://httpbin.org/post 請(qǐng)求數(shù)據(jù): name=張三&age=12

Python3 http.client

import http.client
import urllib.parse

conn = http.client.HTTPConnection("httpbin.org")
data = urllib.parse.urlencode({"name":"張三", "age": 12}).encode("utf-8") # 對(duì)數(shù)據(jù)進(jìn)行url編碼及utf-8編碼
conn.request("POST", '/post', data)
res = conn.getresponse()
print(res.read().decode("utf-8"))

Python3 urllib.request

import urllib
import urllib.parse
import urllib.request

data = urllib.parse.urlencode({"name":"張三", "age": 12}).encode("utf-8") # 對(duì)數(shù)據(jù)進(jìn)行url編碼及utf-8編碼
req = urllib.request.Request("http://httpbin.org/post", data=data)
res = urllib.request.urlopen(req)
print(res.read().decode("utf-8"))

Python3 requests

import requests

data = {"name":"張三", "age": 12}
res = requests.post("http://httpbin.org/post", data=data) # 自動(dòng)編碼
print(res.text)

四、Post application/json請(qǐng)求

POST http://httpbin.org/post 請(qǐng)求數(shù)據(jù): {"name": "張三","age": 12}

Python3 http.client

import http.client
import urllib.parse
import json

conn = http.client.HTTPConnection("httpbin.org")
data = '{"name":"張三", "age": 12}'.encode('utf-8') # 或data = json.dumps({"name":"張三", "age": 12})
headers = {"Content-Type": "application/json"}
conn.request("POST", '/post', data, headers)
res = conn.getresponse()
print(res.read().decode("utf-8"))

Python3 urllib.request

import urllib
import urllib.parse
import urllib.request
import json

data = '{"name":"張三", "age": 12}'.encode('utf-8') # 或data = json.dumps({"name":"張三", "age": 12})
headers = {"Content-Type": "application/json"}
req = urllib.request.Request("http://httpbin.org/post", data=data, headers=headers)
res = urllib.request.urlopen(req)
print(res.read().decode("utf-8"))

Python3 requests

import requests

data = {"name":"張三", "age": 12}
res = requests.post("http://httpbin.org/post", json=data)
print(res.json())? # 轉(zhuǎn)為字典格式

或
import requests
import json

data = {"name":"張三", "age": 12}
headers = {"Content-Type": "application/json"}
res = requests.post("http://httpbin.org/post", data=json.dumps(data), headers=headers)
print(res.json())? # 轉(zhuǎn)為字典格式
