  • china_sms - 短信平台的 Ruby 接口 Gem at 2013年09月28日

    请教各位，我们在用 emay 的接口，使用的专用通道 http 地址与 china_sms 提供的不一样，所以需要修改 URL 地址，感觉这样修有点暴力，求指导

       def use(service, options)
     @service = ChinaSMS::Service.const_get("#{service.to_s.capitalize}")
+    @service.const_set("URL", options[:base_uri]) if options[:base_uri]
     @username = options[:username]
     @password = options[:password]
   end

    详细请看
