使用urllib(2)获取和放置对json数据格式的请求

import urllib.request
import json

url = 'https://api.example.com/data'
response = urllib.request.urlopen(url)
data = json.loads(response.read().decode())

print(data)

import urllib.request
import urllib.parse
import json

url = 'https://api.example.com/data'
headers = {'Content-Type': 'application/json'}
data = json.dumps({'key': 'value'}).encode('utf-8')

req = urllib.request.Request(url, data=data, headers=headers)
response = urllib.request.urlopen(req)
response_data = json.loads(response.read().decode())

print(response_data)

response = urllib.request.urlopen(url, timeout=10)

try:
    response = urllib.request.urlopen(url)
except urllib.error.HTTPError as e:
    print(f'HTTP Error: {e.code} {e.reason}')

data = response.read().decode('utf-8')

import ssl

context = ssl._create_unverified_context()
response = urllib.request.urlopen(url, context=context)
