请求对方机器的端口没有打开，访问的目标地址路由不可达，这个no route to host的报错是由于收到icmp路由不可达报文而导致的。
如果是linux，是iptables阻挡造成的，可以用service iptables stop关闭iptables试试
或者开通防火墙对应的端口
sudo firewall-cmd --zone=public --query-port=28083/tcp
sudo firewall-cmd --zone=public --add-port=28083/tcp --permanent
sudo systemctl restart firewalld
或者命令
firewall-cmd --reload
sudo firewall-cmd --list-ports

在我的Controller中，我通过以下方式在我的index方法中支持HTML和JSON:respond_todo|format|format.htmlformat.json{renderjson:@user}end在浏览器中拉起它时，它会自然地以HTML呈现。但是，当我对/user资源进行内容类型为application/json的curl调用时(因为它是索引方法)，我仍然将HTML作为响应。如何获取JSON作为响应？我还需要说明什么？ 最佳答案 您应该将.json附加到请求的url，提供的格式在routes.rb的路径中定义。这

我有一个具有“名称”属性和“标签”属性的照片类。我的目标是在Rails中实现一个更新功能，用输入的内容替换照片的标签。例如，如果我尝试PUT一个将“标签”设置为[]的JSON对象，我希望从照片中清除任何标签。但是，当我通过HTTParty提交一个空数组作为主体参数之一时，我相信HTTParty正在将[]翻译成nil。因此，我的Rails后端的photos#update端点没有接收到任何参数“tags”。我正在寻找一种方法让HTTParty不将[]转换为nil，因为我失去了从照片中删除标签的能力。 最佳答案 这是Rails4中的一个错
