我从inets User's Guide复制了以下代码：

$ erl
Erlang/OTP 19 [erts-8.2] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V8.2  (abort with ^G)

1> inets:start().
ok

2> httpc:set_options([{proxy, {{"www-proxy.mycompany.com", 8000}, ["localhost"]}}]).
ok

3> {ok, {{Version, 200, ReasonPhrase}, Headers, Body}} = httpc:request("http://www.erlang.org").
* exception error: no match of right hand side value 
                {error,
                    {failed_connect,
                        [{to_address,{"www-proxy.mycompany.com",8000}},
                         {inet,[inet],etimedout}]}}

我需要有关如何使该请求成功完成的建议。

这似乎有效：

$ erl
Erlang/OTP 19 [erts-8.2] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V8.2  (abort with ^G)

1> inets:start().
ok

2> {ok, {{Version, 200, ReasonPhrase}, Headers, Body}} = httpc:request("http://www.erlang.org").
{ok,{{"HTTP/1.1",200,"OK"},
     [{"connection","keep-alive"},
      {"date","Sun, 25 Feb 2018 13:44:59 GMT"},
      {"server","nginx"},
      {"vary","Accept-Encoding"},
      {"content-length","12816"},
      {"content-type","text/html; charset=UTF-8"}],
     "<!DOCTYPE html>\n<html>\n  <head>\n    <title>Erlang Programming Language</title>\n    <meta http-equiv=\"Content-Type\" content=\"text/html;charset=utf-8\"/>\n    <meta name=\"description\" content=\"Erlang Programming Language\"/>\n    <meta name=\"keywords\" content=\"erlang, functional, programming, fault-tolerant, distributed, multi-platform, portable, software, multi-core, smp, concurrency\"/>\n

用户指南说：

以下调用使用默认客户端配置文件。使用代理“www-proxy.mycompany.com:8000”，对本地主机的请求除外。这适用于以下所有请求。

这对我来说很有意义：

Maecenas 在 tincidunt 直径。Pellentesque in orci sed dolor vulputate tincidunt。Etiam malesuada finibus nisi。Lorem ipsum dolor sit amet, consectetur adipiscing elit。

要停止客户端，我是否只需执行以下操作：

  inets:stop()

?

编辑：我一定想出了如何停止服务器，因为我在这段代码中做到了：

Erlang 读取帖子请求
