在Python爬虫中，处理HTTP请求问题是常见的挑战。这里我们将解析一些常见的HTTP请求问题：

发起GET请求：

import requests
url = "http://example.com"
response = requests.get(url)
if response.status_code == 200:
    print("GET request successful.")
    content = response.text
    # 处理获取内容
else:
    print(f"GET request failed with status {response.status_code}."))

处理POST请求：

import requests
url = "http://example.com/api/data"
data = {"key1": "value1", "key2": "value2"}
response = requests.post(url, json=data)
if response.status_code == 201:
    print("POST request successful.")
    content = response.json()
    # 处理返回内容
else:
    print(f"POST request failed with status {response.status_code}."))

处理重定向：

import requests
url = "http://example.com/redirected"
response = requests.get(url, allow_redirects=True))
if response.status_code == 200:
    print("Redirect handled successfully.")
    content = response.text
    # 处理重定向内容
else:
    print(f"Failed to handle redirect with status {response.status_code}."))
