通过特定网络接口发送http请求 [英] Send http request through specific network interface

问题描述

我有两个网络接口(wifi 和以太网)都可以访问互联网.假设我的接口是 eth(以太网)和 wlp2(wifi).我需要通过 eth 接口和其他通过 wpl2 的特定请求.

I have two network interfaces (wifi and ethernet) both with internet access. Let's say my interfaces are eth (ethernet) and wlp2 (wifi). I need specific requests to go through eth interface and others through wpl2.

类似于:

// Through "eth"
request.post(url="http://myapi.com/store_ip", iface="eth")
// Through "wlp2" 
request.post(url="http://myapi.com/log", iface="wlp2")

我正在使用 requests，但如果没有任何方法可以使用 或 urllib，我可以使用 pycurl 或 urllib>请求.

I'm using requests, but I can use pycurl or urllib if there isn't any way to do it with requests.

如何在python请求模块中指定源接口? 指的是 请求，绑定到 ip 并且它不起作用.

How to specify source interface in python requests module? refers to Requests, bind to an ip and it doesn't work.

推荐答案

我找到了一种使用 pycurl 的方法.这就像一个魅力.

I found a way using pycurl. This works like a charm.

import pycurl
from io import BytesIO
import json


def curl_post(url, data, iface=None):
    c = pycurl.Curl()
    buffer = BytesIO()
    c.setopt(pycurl.URL, url)
    c.setopt(pycurl.POST, True)
    c.setopt(pycurl.HTTPHEADER, ['Content-Type: application/json'])
    c.setopt(pycurl.TIMEOUT, 10)
    c.setopt(pycurl.WRITEFUNCTION, buffer.write)
    c.setopt(pycurl.POSTFIELDS, data)
    if iface:
        c.setopt(pycurl.INTERFACE, iface)
    c.perform()

    # Json response
    resp = buffer.getvalue().decode('UTF-8')

    #  Check response is a JSON if not there was an error
    try:
        resp = json.loads(resp)
    except json.decoder.JSONDecodeError:
        pass

    buffer.close()
    c.close()
    return resp


if __name__ == '__main__':
    dat = {"id": 52, "configuration": [{"eno1": {"address": "192.168.1.1"}}]}
    res = curl_post("http://127.0.0.1:5000/network_configuration/", json.dumps(dat), "wlp2")
    print(res)

我将问题悬而未决，希望有人可以使用 requests 给出答案.

I'm leaving the question opened hopping that someone can give an answer using requests.
