无法使用 ip:port 访问 WEB API，但可以在 VS 调试模式下使用 localhost:port

Can#39;t access WEB API with ip:port but can with localhost:port during VS debug mode(无法使用 ip:port 访问 WEB API，但可以在 VS 调试模式下使用 localhost:port)

问题描述

I am trying to write an WEB API from .net and trying for my Android Application to query some data from the sql server database.

I have the web api written and it works well in debug mode.

My question is I notice the url of that application is localhost:port and it runs fine. However, when I try to change it to MYIP:port (eg. http:192.168.X.1234) or MYHOSTNAME:port (eg win7home:1234) this gives me Bad Request - Invalid Hostname.

I know I can deploy this to IIS and my IIS is setup but I was just wondering how come it doesn't work in debug mode???

Is there a way for me to run it in debug mode and test in on my Android at the same time instead of having to deploy it every time I want to make a change?

Both Anton and Matthew's Answers pointed me to the right direction

So this what I did

1. Run Visual Studios in administrator mode

2. Changed the binding protocols and allow for incoming directions as suggested http://johan.driessen.se/posts/Accessing-an-IIS-Express-site-from-a-remote-computer

   But after that, I have a service unavailable (503) error

3. So I followed this : IIS Express Enable External Request - 503 Added just the port protocol and port:ip protocol,

Than it works both on my machine's browser and on my phone.

Not too too sure why the 3rd step is needed -my hypothesis is (the localhost url is needed for VS to point to and the ip url is used for accessing from another machine)
