I am trying to make a Http request, like the following:
var category = Uri.EscapeDataString("Power Tools");
var request = new HttpRequestMessage(HttpMethod.Get, $"/api/Items/GetAll?category={category}");
category now equals: Power%20Tools
The request gets translated to:
request = {Method: GET, RequestUri: 'http://localhost/api/Items/GetAll?category=Power Tools', ...
Why is HttpRequestMessage decoding my encoded string?
I reproduce in Console app in .NET 5. I think, it's just the ToString that decode the url to be friendly on debug information. I don't find a information to this on the documentation, but .NET is now open source.
Generaly, the method ToString is used to generate debug information. See
See the source code of HttpRequestMessage.ToString :
public override string ToString()
{
StringBuilder sb = new StringBuilder();
sb.Append("Method: ");
sb.Append(method);
sb.Append(", RequestUri: '");
sb.Append(requestUri == null ? "<null>" : requestUri.ToString());
...
return sb.ToString();
}
This just display requsetUri.ToString() and requestUri is type of Uri.
From the official documentation of Uri.String:
The unescaped canonical representation of the Uri instance. All characters are unescaped except #, ?, and %.
// Create a new Uri from a string address.
Uri uriAddress = new Uri("HTTP://www.Contoso.com:80/thick%20and%20thin.htm");
// Write the new Uri to the console and note the difference in the two values.
// ToString() gives the canonical version. OriginalString gives the orginal
// string that was passed to the constructor.
// The following outputs "http://www.contoso.com/thick and thin.htm".
Console.WriteLine(uriAddress.ToString());
// The following outputs "HTTP://www.Contoso.com:80/thick%20and%20thin.htm".
Console.WriteLine(uriAddress.OriginalString);
http://localhost/api/Items/GetAll?category=Power%20Tools. However, the controller is seeingPower Toolsand responds with an error message. My regex is^[a-zA-Z0-9%]+$. This works if I add a space to the regex.
