python使用httpclient模块发送post请求并设置代理

可以使用Python的httpclient模块发送POST请求并设置代理，具体步骤如下：

1. 导入httpclient和url模块：

import http.client
import urllib.parse

2. 定义POST请求的url和请求参数：

url = "http://example.com/post"
params = urllib.parse.urlencode({
    "param1": "value1",
    "param2": "value2"
})

3. 设置代理：

proxy_host = "your_proxy_host"
proxy_port = "your_proxy_port"
conn = http.client.HTTPConnection(proxy_host, proxy_port)
conn.set_tunnel("example.com")

4. 发送POST请求：

headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
conn.request("POST", url, params, headers)
response = conn.getresponse()
print(response.read())

完整代码示例：

import http.client
import urllib.parse

url = "http://example.com/post"
params = urllib.parse.urlencode({
    "param1": "value1",
    "param2": "value2"
})

proxy_host = "your_proxy_host"
proxy_port = "your_proxy_port"
conn = http.client.HTTPConnection(proxy_host, proxy_port)
conn.set_tunnel("example.com")

headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
conn.request("POST", url, params, headers)
response = conn.getresponse()
print(response.read())
