Tor

Download and config Tor

https://www.torproject.org/

• $ brew install tor. Refer to https://2019.www.torproject.org/docs/tor-doc-osx.html.en
• $ cp /usr/local/etc/tor/torrc.sample /usr/local/etc/tor/torrc
• Run tor first before running crawl tasks.
• 如果是用 ShadowSocks Client 翻墙上网（往往需要），想让 Tor client 走 ShadowSocks Client 上网，需要向/usr/local/etc/tor/torrc中加一行：Socks5Proxy 127.0.0.1:<PORT>，其中的IP和在 ShadowSocks 的`Advance Preferences`中可以看到。

Run Tor

• $ tor --RunAsDaemon 0 --CookieAuthentication 0 --HashedControlPassword "" --ControlPort 15001 --PidFile tor9001.pid --SocksPort 9001 --DataDirectory ~/tor/log/tor9001 --CircuitBuildTimeout 5 --KeepalivePeriod 60 --NewCircuitPeriod 15 --NumEntryGuards 8 如果启动成功，会看到如下内容：

  ...
  Jan 12 17:56:19.000 [notice] Bootstrapped 0% (starting): Starting
  ...
  Jan 12 17:56:23.000 [notice] Bootstrapped 15% (handshake_done): Handshake with a relay done
  ...
  Jan 12 17:56:23.000 [notice] Bootstrapped 95% (circuit_create): Establishing a Tor circuit
  Jan 12 17:56:24.000 [notice] Bootstrapped 100% (done): Done
  

Check Tor

• https://check.torproject.org/ 可以用来测试目前是否是通过Tor来访问互联网。 curl --socks5 localhost:9001 --socks5-hostname localhost:9001 -s https://check.torproject.org/ | cat | grep -m 1 Congratulations | xargs 显示 Congratulations. This browser is configured to use Tor.

Use Tor

Use Tor in Chrome browser

• Use Chrome extension Proxy SwithyOmega.
• Set the proxy as sock5 and localhost, port 9001(tor default port is 9050).

Use Tor in code

# These code is just a sample. Not correct.
proxy = 'socks5://localhost:9001'
driver=selenium.webdriver.Chrome
driver_options={'options': chrome_options_builder.get_options()}
driver(**driver_options)
chrome_options_builder = ChromeOptionsBuilder(device=device, proxy=proxy)

torify

关于torify的以下内容仅供参考，可以跳过。torify是安装好Tor后自带一个command工具，帮助你查看走Tor访问URL时对应的IP。 Mac下需要先$ brew install torsocks，然后$ cp /usr/bin/curl /usr/local/bin，$ torify /usr/local/bin/curl http://kong.getscroll.com/ip。 不过即使做到这步，还是会报错，因为默认的Tor的SocksPort是9050，torify认准了9050端口了，即使我改/usr/local/etc/tor/torrc中的SOCKSPort也不会使torify去读，所以启动Tor时要用tor --SocksPort 9050才能用torify。
