如何在Docker Compose中通过Srivpy和Tor通过Privoxy使用Tor

本文介绍了如何在Docker Compose中通过Srivpy和Tor通过Privoxy使用Tor的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试运行具有两个扩展名的Scrapy蜘蛛：

I'm trying to run a Scrapy spider with two 'extensions':


  1. 用于呈现JavaScript，

  2. 提供匿名。

  1. Splash for rendering JavaScript,
  2. Tor-Privoxy to provide anonymity.

例如，我在quotes.toscrape.com 的抓取器/ tree / master / example rel = noreferrer> https://github.com/scrapy-plugins/scrapy-splash/tree/master/example 。这是我的目录结构：

As an example, I'm using the scraper of quotes.toscrape.com in https://github.com/scrapy-plugins/scrapy-splash/tree/master/example. Here is my directory structure:

.
├── docker-compose.yml
└── example
    ├── Dockerfile
    ├── scrapy.cfg
    └── scrashtest
        ├── __init__.py
        ├── settings.py
        └── spiders
            ├── __init__.py
            └── quotes.py

其中 example 目录是从克隆的scrapy-splash 存储库。我添加了以下 docker-compose.yml 文件：

where the example directory is cloned from the scrapy-splash repository. I've added the following docker-compose.yml file:

version: '3'

services:
  scraper:
    build: ./example
    environment:
      - http_proxy=http://tor-privoxy:8118
    links:
      - tor-privoxy
      - splash

  tor-privoxy:
    image: rdsubhas/tor-privoxy-alpine

  splash:
    image: scrapinghub/splash

其中 settings.py 文件我已经更改了 SPLASH_URL ：

where in the settings.py file I've changed the SPLASH_URL:

# SPLASH_URL = 'http://127.0.0.1:8050/'
SPLASH_URL = 'http://splash:8050'

因为Splash不在本地主机上运行，​​而是在名为 splash 的单独的链接容器中运行。 刮板的 Dockerfile 是

Because Splash is running not on the localhost, but in a separate linked container named splash. The Dockerfile for the scraper is

FROM python:alpine
RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl bash
RUN pip install scrapy scrapy-splash
COPY . /scraper
WORKDIR /scraper
CMD ["scrapy", "crawl", "quotes"]

问题是，当我使用 docker-compose build 和 docker-compose up 运行此程序时，我得到以下日志：

The problem is that when I run this using docker-compose build and docker-compose up, I get the following logs:

为简便起见，我在此中断了该过程。似乎刮板和 tor-privoxy 服务交替抱怨 500内部服务错误并且无法解析或连接到地址。

where I've interrupted the process for brevity. It seems like the scraper and tor-privoxy services are alternately complaining about a 500 Internal Service Error and not being able to 'resolve or connect to address', respectively.

我正在努力弄清为什么 http_proxy 和Splash不能一起工作。有人能指出我正确的方向吗？

I'm struggling to figure out why the http_proxy and Splash don't 'work together'. Can anyone point me in the right direction?

推荐答案

在Aquarium模板项目之后（），我发现诀窍是使Splash使用Tor，而不是蜘蛛直。

Following the Aquarium template project (https://github.com/TeamHG-Memex/aquarium), I found that the trick is to make Splash use Tor, not the spider directly.

我适应的项目具有以下结构：

My adapted project has the following structure:

.
├── docker-compose.yml
├── example
│   ├── Dockerfile
│   ├── scrapy.cfg
│   └── scrashtest
│       ├── __init__.py
│       ├── settings.py
│       └── spiders
│           ├── __init__.py
│           └── quotes.py
└── splash
    └── proxy-profiles
        └── default.ini

和 docker-compose.yml 是

version: '3'

services:
  scraper:
    build: ./example
    links:
      - splash

  tor-privoxy:
    image: rdsubhas/tor-privoxy-alpine

  splash:
    image: scrapinghub/splash
    volumes:
      - ./splash/proxy-profiles:/etc/splash/proxy-profiles:ro
    links:
      - tor-privoxy

我已将代理配置文件目录作为卷装入到 splash 容器跟随。 default.ini 读取

where I've mounted the proxy-profiles directory as a volume into the splash container following http://splash.readthedocs.io/en/stable/api.html#proxy-profiles. The default.ini reads

[proxy]

host=tor-privoxy
port=8118

（我也注意到这是将其命名为 default.ini ）。

(I also noticed it is essential to call it default.ini).

通过此设置，在 docker-组成build 和 docker-compose up ，该刮板使用Splash成功运行。

With this setup, upon docker-compose build and docker-compose up the scraper runs successfully using Splash.

这篇关于如何在Docker Compose中通过Srivpy和Tor通过Privoxy使用Tor的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
