Access localhost on Mac from XCode? Phonegap communicating with Ajax to a local Rails app
提问by Lance Pollard
Is there a way to access http://localhost:3000/postsfrom within an HTML file that's running through Phonegap for the iPhone on the iPhone device (not the simulator), in XCode?
有没有办法http://localhost:3000/posts在 XCode 中从 iPhone 设备（不是模拟器）上的 iPhone 的 Phonegap 运行的 HTML 文件中进行访问？
If I have an HTML5 app in Phonegap, I have only been able to access external stylesheets with file://Users/etc..or http://...when I'm testing it on the iPhone/iPad itself. If I'm running the simulator, I can access localhost no problem.
如果我在 Phonegap 中有一个 HTML5 应用程序，我只能使用file://Users/etc..或http://...在我在 iPhone/iPad 本身上测试它时访问外部样式表。如果我正在运行模拟器，则可以访问 localhost 没问题。
Is there a way around this? I know I can access localhost on the Mac from within Parallels running Windows by doing http://username.local/posts, is there something like this for iOS development?
有没有解决的办法？我知道我可以从运行 Windows 的 Parallels 中访问 Mac 上的 localhost http://username.local/posts，iOS 开发有没有类似的东西？

"localhost" always points to 127.0.0.1in IPv4, which is the current device's loopback network interface. If you open "localhost" from your iPhone, it will point to the iPhone itself.
“localhost”始终指向127.0.0.1IPv4，即当前设备的环回网络接口。如果您从 iPhone 打开“localhost”，它将指向 iPhone 本身。
However, if you are in the same network as your Mac, you can simply use your Mac's IP address, e.g. http://192.168.0.20:3000/posts. You can see your current IP address in your Mac's Network Settings.
但是，如果您与 Mac 位于同一网络中，则只需使用 Mac 的 IP 地址，例如http://192.168.0.20:3000/posts. 您可以在 Mac 的网络设置中查看您当前的 IP 地址。
Also, depending on your network configuration, using the Bonjour name might work as well. For example: http://mymac.local:3000/postsif the name of your computer is set to mymacin the system preferences' Sharingpane.
此外，根据您的网络配置，使用 Bonjour 名称也可能有效。例如：http://mymac.local:3000/posts如果您的计算机名称mymac在系统首选项的Sharing面板中设置为。

If you are asking whether you can access localhost on your Mac/PC from your iPhone device, then the answer is no. There's no way for your iPhone to route to another machine's local host address.
如果您问是否可以从 iPhone 设备访问 Mac/PC 上的 localhost，那么答案是否定的。您的 iPhone 无法路由到另一台机器的本地主机地址。
You should get your iPhone on the network that the server resides on and use an accessible IP address to access it.
您应该将 iPhone 连接到服务器所在的网络，并使用可访问的 IP 地址来访问它。
