python / django中的Web代理？ [英] Web proxy in python/django?

问题描述

我需要一个代理作为获取图像的中介。一个例子是，我的服务器请求domain1.com/?url=domain2.com/image.png和domain1.com服务器将通过domain1.com服务器在domain2.com/image.png上回复数据。

本质上，我想将代理传递给我想要获取的URL，并让代理服务器响应该资源。

关于从哪里开始的任何建议？

我需要一些非常容易使用或实现的东西，因为我非常喜欢这一切的初学者。

我在python和/或django中找到的大多数解决方案都有代理作为翻译器，即domain1.com/image.png转换为domain2.com/image.png，其中显然不一样。

我目前有以下代码，但是获取图像会导致乱码数据：

  import httplib2 
 from django.conf.urls.defaults import * 
 from django.http import HttpResponse 
 
 def proxy（request，url ）：
 conn = httplib2.Http（）
如果request.method ==GET：
 url = request.GET ['url'] 
 resp，content = conn.request（url，request.method）
 return HttpResponse（content） 
  

解决方案

旧问题，但对于未来的Google员工，我认为这是你想要什么：

 ＃代理google标志
 def test（request）：
 url = $ http：//www.google.com/logos/classicplus.png
 req = urllib2.Request（url）
 response = urllib2.urlopen（req）
 return HttpResponse（response.read （），mimetype =image / png）
  

I need to have a proxy that acts as an intermediary to fetch images. An example would be, my server requests domain1.com/?url=domain2.com/image.png and domain1.com server will respond with the data at domain2.com/image.png via domain1.com server.

Essentially I want to pass to the proxy the URL I want fetched, and have the proxy server respond with that resource.

Any suggestions on where to start on this?

I need something very easy to use or implement as I'm very much a beginner at all of this.

Most solutions I have found in python and/or django have the proxy acts as a "translater" i.e. domain1.com/image.png translates to domain2.com/image.png, which is obviously not the same.

I currently have the following code, but fetching images results in garbled data:

import httplib2
from django.conf.urls.defaults import *
from django.http import HttpResponse

def proxy(request, url):
    conn = httplib2.Http()
    if request.method == "GET":
        url = request.GET['url']
        resp, content = conn.request(url, request.method)
        return HttpResponse(content)

解决方案

Old question but for future googlers, I think this is what you want:

# proxies the google logo
def test(request):
    url = "http://www.google.com/logos/classicplus.png"
    req = urllib2.Request(url)
    response = urllib2.urlopen(req)
    return HttpResponse(response.read(), mimetype="image/png")
