以下是“获取”方法：
def self.get(url, params={})
url = API_DOMAIN + url + '.json'
uri = URI.parse(url)
uri.query = URI.encode_www_form(params)
http = Net::HTTP.new(uri.host,uri.port)
path = uri.path
path += "?#{uri.query}" if uri.query
request = Net::HTTP::Get.new(path)
response = http.request(request)
return response
end
奇怪的是，这个错误似乎只发生在最后 2 天。有没有人最近遇到过类似的问题？
