文档中关于 timeout 的说明有歧义

[yiichou]

文档中提到：

Wechat server timeout setting

Stability various even for Tencent wechat server, so setting a long timeout may needed, default is 20 seconds if not set.

通常来说，用户都会以为默认是请求超过 20 秒就会被判定为超时，并中断

但实际上：

# lib/wechat/http_client.rb line 9 in wechat.gem
# timeout = 20 by default
@httprb = HTTP.timeout(:global, write: timeout, connect: timeout, read: timeout)

# lib/http/timeout/global.rb in http.gem
def initialize(*args)
  super
  reset_counter
end

# To future me: Don't remove this again, past you was smarter.
def reset_counter
  @time_left = connect_timeout + read_timeout + write_timeout
  @total_timeout = time_left
end

也就是说，实际允许的超时时间最大可能是设定值的 3 倍，即 60 秒.

欢迎PR，这部分timeout之前是基于rest client的，后来换到http后没更新，现在http的timeout控制确实精细了不少。

借楼问下... @Eric-Guo 为什么把rest-client切换到http？因为我也在做类似的封装0.0

速度快，可以保持http连接。
