如何在Python中重放原始HTTP请求？

针对你需要自动解析原始HTTP请求、同时保留TLS和代理支持的需求，以下是几个实用的解决方案，无需手动拆分请求行和请求头：

1. 使用 httpx 直接发送原始请求 #

httpx 是支持HTTP/1.1和HTTP/2的现代HTTP客户端，原生支持直接传入原始请求字符串，自动处理解析、TLS加密和代理配置：

import httpx

# 你的原始HTTP请求文本
raw_request = """GET / HTTP/1.1
Host: google.de
Cookie: CONSENT=PENDING+071; AEC=ARSKqsKvfEvPS9Vp1bDM6YMPdHpVOoH357W-7q3cqtdDwYeHf3MqPEO1xA; SOCS=CAISHAgBEhJnd3NfMjAyMzAyMjMtMF9SQzEaAmRlIAEaBgiAn-WfBg; NID=511=N6YvXcWd_hnVVnV8w6JK4jscqE2pEt8MuTrw3yZJp-84ZxV6RJLee_yj2DEo2UJuOse0sqLjdnAD7qgPw9al7aEJqsQOCAQPIs21rLy5HQ5IAoObj7icI7ayKJttejI9Va2jDFkk0ZLvUC7P_VPJuxRJyhvLspqU1YVUcYCThrYizbo; 1P_JAR=2023-2-25-20

# 配置代理（不需要可删除proxies参数）
proxies = {"http": "http://your-proxy:port", "https": "http://your-proxy:port"}

with httpx.Client(proxies=proxies) as client:
    # 发送原始请求
    response = client.send(httpx.Request("GET", "https://google.de"), content=raw_request.encode('utf-8'))
    print(f"状态码: {response.status_code}")
    print(f"响应内容预览: {response.text[:500]}")

2. 用 requests 配合标准库解析原始请求 #

如果你更习惯使用requests，可以借助Python标准库http.client自动解析原始请求文本，提取方法、路径、请求头和请求体，再生成requests预请求对象：

import requests
from http.client import HTTPMessage

def parse_raw_request(raw_request):
    # 拆分请求行与请求头
    lines = raw_request.split('\r\n')
    method, path, _ = lines[0].split()
    
    # 解析请求头
    msg = HTTPMessage()
    for line in lines[1:]:
        if not line:
            break
        key, value = line.split(': ', 1)
        msg.add_header(key, value)
    
    # 提取请求体（如果存在）
    body = '\r\n'.join(lines[lines.index('')+1:]) if '' in lines else ''
    return method, path, dict(msg.items()), body

# 你的原始请求文本
raw_request = """GET / HTTP/1.1
Host: google.de
Cookie: CONSENT=PENDING+071; AEC=ARSKqsKvfEvPS9Vp1bDM6YMPdHpVOoH357W-7q3cqtdDwYeHf3MqPEO1xA; SOCS=CAISHAgBEhJnd3NfMjAyMzAyMjMtMF9SQzEaAmRlIAEaBgiAn-WfBg; NID=511=N6YvXcWd_hnVVnV8w6JK4jscqE2pEt8MuTrw3yZJp-84ZxV6RJLee_yj2DEo2UJuOse0sqLjdnAD7qgPw9al7aEJqsQOCAQPIs21rLy5HQ5IAoObj7icI7ayKJttejI9Va2jDFkk0ZLvUC7P_VPJuxRJyhvLspqU1YVUcYCThrYizbo; 1P_JAR=2023-2-25-20

"""

method, path, headers, body = parse_raw_request(raw_request)
url = f"https://{headers['Host']}{path}"

# 配置代理（不需要可删除proxies参数）
proxies = {"http": "http://your-proxy:port", "https": "http://your-proxy:port"}

with requests.Session() as s:
    req = requests.Request(method, url, headers=headers, data=body.encode('utf-8'))
    prepped = req.prepare()
    # 发送请求，支持TLS验证、代理等参数
    resp = s.send(prepped, proxies=proxies, verify=True)
    print(f"状态码: {resp.status_code}")
    print(f"响应内容预览: {resp.text[:500]}")

3. 使用专门的 rawhttp 库 #

rawhttp 是专为处理原始HTTP请求设计的第三方库，支持直接发送原始请求字符串，同时内置TLS和代理支持：

先安装库：

pip install rawhttp

使用示例：

from rawhttp import RawHTTP

raw_request = """GET / HTTP/1.1
Host: google.de
Cookie: CONSENT=PENDING+071; AEC=ARSKqsKvfEvPS9Vp1bDM6YMPdHpVOoH357W-7q3cqtdDwYeHf3MqPEO1xA; SOCS=CAISHAgBEhJnd3NfMjAyMzAyMjMtMF9SQzEaAmRlIAEaBgiAn-WfBg; NID=511=N6YvXcWd_hnVVnV8w6JK4jscqE2pEt8MuTrw3yZJp-84ZxV6RJLee_yj2DEo2UJuOse0sqLjdnAD7qgPw9al7aEJqsQOCAQPIs21rLy5HQ5IAoObj7icI7ayKJttejI9Va2jDFkk0ZLvUC7P_VPJuxRJyhvLspqU1YVUcYCThrYizbo; 1P_JAR=2023-2-25-20
Sec-Ch-Ua: "Not A(Brand";v="24", "Chromium";v="110"
Sec-Ch-Ua-Mobile: ?0
Sec-Ch-Ua-Platform: "Linux"
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.5481.78 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7
X-Client-Data: CO3/ygE=
Sec-Fetch-Site: none
Sec-Fetch-Mode: navigate
Sec-Fetch-User: ?1
Sec-Fetch-Dest: document
Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.9
Connection: close
"""

# 发送HTTPS请求，配置代理（不需要可删除proxy参数）
response = RawHTTP().send(raw_request, url='https://google.de', proxy='http://your-proxy:port')
print(f"状态行: {response.status_line}")
print(f"响应头: {dict(response.headers)}")
print(f"响应内容预览: {response.body[:500]}")

以上方案均无需手动解析请求头，同时保留了TLS加密和代理支持，可直接满足你重放原始HTTP请求的需求。
