到目前为止你有什么？您需要（我猜）基本的Web凭据，例如

 using（WebClient client = new WebClient（））
 {
 client.Credentials = new NetworkCredential（" username"，" password"）; 
 // .. 
} 

Hello Everybody,

For the last few hours I've been trying to receive a simple JSON object from a rest https api that requires username and password.

The company provided a working example in Javasccript how to get the info. I don't know javascript, only c#, but I can't seem to make it work. Probably because I'm not familiar with wen http requests etc.

This is the working JS code:

function signin(){
            username = $('#inputUsername').val();
            pass = $('#inputPassword').val();
            if(pass.length > 0 && username.length > 0){
                //Build post request
                $.post( source+"/login", {username: username, password:pass}, function( data, textStatus, jqxhr ) {
                    $("header div h4#header_username").html(username);
                    token = data.auth;
                    $('#main-content').show()
                    $('#form-signin').hide()
                    populateVehicles();
                });
            }
        }

Could anyone help me convert it to c#? I've been trying to use HttpClient or HttpRequest and each time I receive a 401 Unauthorized Error or Bad Request Error.

Thanks in advance.

Found the solution. Sending the credentials worked only like this. Hope it helps.

                var data = new NameValueCollection();
                data["username"] = "USERNAME";
                data["password"] = "PASSWORD";

                var response = wb.UploadValues("URL", "POST", data);

What have you so far? You need (I guess) basic web credentials, something like

using (WebClient client = new WebClient())
{
    client.Credentials = new NetworkCredential("username", "password");
    //..
}
