python服务器中发送外部请求的基本步骤

pip install requests

import requests
# 目标URL
url = 'https://api.example.com/data'
# 发送GET请求
response = requests.get(url)
# 检查请求是否成功
if response.status_code == 200:
    # 处理响应数据
    data = response.json()  # 假设返回的是JSON数据
    print(data)
else:
    print(f"请求失败，状态码：{response.status_code}")

import requests
# 目标URL
url = 'https://api.example.com/data'
# 要发送的数据
data = {
    'key1': 'value1',
    'key2': 'value2'
}
# 发送POST请求
response = requests.post(url, data=data)
# 检查请求是否成功
if response.status_code == 200:
    # 处理响应数据
    print(response.text)  # 或者使用response.json()来处理JSON响应
else:
    print(f"请求失败，状态码：{response.status_code}")

import requests
url = 'https://api.example.com/data'
headers = {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_ACCESS_TOKEN'
}
data = {'key': 'value'}
response = requests.post(url, json=data, headers=headers)
if response.status_code == 200:
    print(response.json())
else:
    print(f"请求失败，状态码：{response.status_code}")

import requests
try:
    response = requests.get('https://some-nonexistent-domain.com')
    response.raise_for_status()  # 如果响应状态码不是200，则抛出HTTPError异常
except requests.exceptions.RequestException as e:
    print(e)
