他们怎么想的，这还正常啊。看了最后一行，状态是 open 的，估计还在修。

这里有个坑：

Please consider reverse-proxying https://api.rubygems.org/api/v1/dependencies at /rubygems/api/v1/dependencies so that dependency lists are fetched through this API, instead of calculated locally, by downloading and parsing all gemspec.rz files.

For your reference, here is a Caddyfile that I use to test the feasibility of the reverse proxy:

localhost:8081
log stderr

proxy /rubygems https://mirrors.tuna.tsinghua.edu.cn {
    except /rubygems/api
}

proxy /rubygems/api https://api.rubygems.org {
    without /rubygems
}

(I am fully aware of the "we don't do reverse proxy" policy of this site, so this is only filed in the hope of being useful to all RubyGems mirror users)

命令是：

gem install nokogiri -VN

兼容 linux 和苹果系统:

require "url"
require "json"

url = URL.new("https://view.inews.qq.com/g2/getOnsInfo?name=disease_h5&callback")
response = url.get.json
data = JSON.parse response["data"]

puts data["lastUpdateTime"]

def show_data(data)
  for item in data["areaTree"]
    s=(item["name"].to_s + "累计确诊：" + item["total"]["confirm"].to_s + "例，死亡：" + item["total"]["dead"].to_s + "例，治愈：" + item["total"]["heal"].to_s + "例;")
    if Gem.win_platform?
      puts s.encode("gbk")
    else
      puts s
    end                                                                                  
  end
end

show_data(data)

如果有依赖呢?

其实就是什么文章都能写上去,国外没有做限制. 国内可以做个限制就没事了.

被墙了,要不再山寨一个?

简单，可以先定义一个空函数:

#1.rb
def f(x)
  puts " f()未定义" 
end

再定义实际使用的函数：

#2.rb
def f(x)
  puts "f() 已定义" 
end

然后在 3.rb 里， require '2.rb' 就可以了。

require 'digest'

s = '{"Limit": 1, "Filters": [{"Values": ["\u672a\u547d\u540d"], "Name": "instance-name"}]}'

print Digest::SHA2.new(256).hexdigest(s).downcase
