C# Blazor client-side read hash parameters from url










2















I have a project in Blazor



And on the client-side, I want to read hash parameters



I know how to do it in JavaScript - but my question is how to do it in c# client-side in Blazor project



For example, I have an URL http://localhost:5060/#token=12345678



How to take token?



my code in index.cshtml



@page "/"
@inject Microsoft.AspNetCore.Blazor.Services.IUriHelper UriHelper

<h1>Hello, world!</h1>

url is @Url

@functions
protected override void OnInit()
Url = GetUrl();


public string Url get; set;

public string GetUrl()
return ?;

  • By the way, perhaps you could change your URL to use "route parameters". This could perhaps make it easier to map the token to a component property (see here: codedaze.io/blazor-bites-routing). Although, i have to admit i haven't done anything like that myself, so i might talk complete bollocks here ;-)

If you can do it in JavaScript, then use JavaScript Interop:
1. Define a JavaScript function which extract the token.
2. Define a C# method which call the function



But it would be still better to do that with Blazor which itself use JavaScript...
What you need is to look at the methods defined in Microsoft.AspNetCore.Blazor.Services.UriHelperBase and/or
Microsoft.AspNetCore.Blazor.Browser.Services.BrowserUriHelper



Hope this helps...



Note: the <base> element is set in the Index.Html file located in the
wwwroot folder.




"The HTML <base> element specifies the base URL to use for all
relative URLs contained within a document. There can be only one
element in a document.



The base URL of a document can be queried from a script using
document.baseURI."




Try this:



var absoluteUrl = UriHelper.GetAbsoluteUri();
var token = absoluteUrl.Substring(absoluteUrl.IndexOf("=") + 1);

    For reading hash parameters in C# Blazor without JavaScript or other client-side solutions I need to change function, like in the code below:



    @functions 
    private string url = string.Empty;

    protected override void OnInit()
    string url = UriHelper.GetAbsoluteUri();
    string parameters = url .Replace(UriHelper.GetBaseUri(), "").Replace("#", "").Split('&');

    string token = string.Empty;

    foreach (string prm in parameters)
    if (prm.IndexOf("token=") >= 0)
    token = prm.Replace("token=", "");



    UriHelper.OnLocationChanged += OnLocationChanged;


    private void OnLocationChanged(object sender, string newUriAbsolute)
