Gitment 迁移到 Gitalk 的脚本，处理 label 的重命名

gitment2gitalk.rb

require 'openssl'
require 'json'
require 'net/http'
require 'cgi'
require 'digest'

repo = "kemchenj.github.io"
owner = "kemchenj"
account = "account"
password = "password"

base_uri = URI("https://api.github.com/")

# 获取所有 Label
repo_params = { "per_page": 1000 }
repo_uri = URI.join(base_uri.to_s, "repos/#{owner}/#{repo}/labels")
repo_uri.query = URI.encode_www_form(repo_params)

labels = JSON.parse(Net::HTTP.get(repo_uri))

# Label 逐个 MD5 重命名
labels
  .map { |l| l["name"] }
  .filter { |n| n.include?("/") }
  .each { |l|
    old = l.to_s
    new = Digest::MD5.hexdigest old

    p JSON.generate({ "old": old, "new": new })

    label_uri = URI.join(base_uri.to_s, "s/#{owner}/#{repo}/labels/#{CGI.escape(old)}")

    req = Net::HTTP::Patch.new(label_uri)
    req.body = JSON.generate({ "name": new })
    # 这里偷懒直接用了 basic auth
    req.basic_auth account, password
    req["Content-Type"] = "application/json"

    res = Net::HTTP.start(label_uri.host, label_uri.port, :use_ssl => true) do |http|
      http.request(req)
    end
  }
