http-proxy

http-proxy 能够把 socks5 代理转换为 http 代理，另外，可以根据 IP 段来 决定哪些 IP 应该走 socks5，哪些 IP 应该直连。 这对于经常从国内外服务器拉取代码的人非常有用。

例如，因为一些原因，我们拉取或推送代码到 github 时，速度非常慢，因此我 们需要配置 git 的 http(s).proxy，当我们需要拉取国内源的代码时，我们又需 要取消 git 的 http(s).proxy 设置。

通过 http-proxy 我们仅需要配置一次，然后，是否需要通过 socks5 代理，可由 http-proxy 自动决定。

Http proxy. With http-proxy, you can assign a socks5 proxy as upstream proxy, and, use "chnroute" to by pass proxy.

Note:

With "--chnroute", you should make sure that the dns resolve result is clean. You can use CleanDNS, ChinaDNS or similar utilities to get clean dns result.

Usage

$>http-proxy -h

http-proxy 0.0.1

Usage:

http-proxy [-b BIND_ADDR] [-p BIND_PORT] [--config=CONFIG_PATH]
         [--log=LOG_FILE_PATH] [--log-level=LOG_LEVEL]
         [--chnroute=CHNROUTE_FILE] [--proxy=SOCKS5_PROXY]
         [--daemon] [--pid=PID_FILE_PATH] [-v] [-V] [-h]

Http proxy. With http-proxy, you can assign a socks5 proxy as upstream proxy.
And, use "chnroute" to by pass proxy.

Note:
  With "--chnroute", you should make sure that the dns resolve result is clean.
  You can use CleanDNS (https://github.com/GangZhuo/CleanDNS),
  ChinaDNS (https://github.com/shadowsocks/ChinaDNS) or similar utilities to
  get clean dns result.

Options:

  -b BIND_ADDR             Address that listens, default: 0.0.0.0.
                           Use comma to separate multi addresses,
                           e.g. -b 127.0.0.1:5354,[::1]:5354.
  -p BIND_PORT             Port that listen on, default: 1080.
                           The port specified in "-b" is priority .
  -t TIMEOUT               Timeout (seconds), default: 30.
  --dns-server=DNS_SERVER  DNS servers, e.g. 192.168.1.1:53,8.8.8.8.
  --dns-timeout=TIMEOUT    DNS cache timeout (seconds), default: 600.
                           0 mean no cache.
  --daemon                 Daemonize.
  --pid=PID_FILE_PATH      pid file, default: /var/run/http-proxy.pid,
                           only available on daemonize.
  --log=LOG_FILE_PATH      Write log to a file.
  --log-level=LOG_LEVEL    Log level, range: [0, 7], default: 5.
  --config=CONFIG_PATH     Config file, find sample at
                           https://github.com/GangZhuo/http-proxy.
  --chnroute=CHNROUTE_FILE Path to china route file,
                           e.g.: --chnroute=lan.txt,chnroute.txt,chnroute6.txt.
  --forbidden=FORBIDDEN_FILE Path to forbidden route file,
                           e.g.: --forbidden=self.txt,youtube.txt.
