How to get the domain name/IP name in web-API?

Question

How can I get the (ipName:PortNumber) mentioned in the below IP address in web-API?

https://**ipName:PortNumber**/ProductController/{productId}

We have diff servers such as: 000.00.000:8080 (ipname:portnumber), 111.11.111:8181.

I want to load these dynamically into a string as shown below.

string webServiceUrl = "https://"+ IP name +"Product Controller/{product Id}"

Answer 1

If you have your URI in a string, you can get the information you want as follows:

Uri uri = new Uri("https://example.com:1234/ProductController/7");
string host = uri.Host; // "example.com"
int port = uri.Port; // 1234

Inside of an ApiController , you can get the current request's URI as Request.RequestUri .

If you want to construct a URI given the host and port, you can simply do something lightweight like this:

string uri = string.Format("https://{0}:{1}/ProductController/7", host, port);

Or something a little more robust like use the UriBuilder class.

Here's how I access the Request object within a Web Api...

if (Request.Properties.ContainsKey("MS_HttpContext"))
{
     var ip = (HttpContextWrapper)Request.Properties["MS_HttpContext"]).Request.UserHostAddress;
     var host = ((HttpContextWrapper)Request.Properties["MS_HttpContext"]).Request.Url.Host;
     var port = ((HttpContextWrapper)Request.Properties["MS_HttpContext"]).Request.Url.Port;
}

Hope it helps.
