Login fails .. part 2

Help
1

This fails in postman and in C#

According to the docs I have all the parameters

string content = “{"client_id" : "MX9ts5N0yPyGQhNWFnGi0RRCCMB92nLd", "connection" : "Form217" , "grant_type" : "password" ,"scope" : "openid", "username" : "” + uname + “", "password" : "” + passwd + “"}”;

HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, uri);

var uri = “https://railcomm.auth0.com/oauth/ro”;

request.Content = new StringContent(content, System.Text.Encoding.UTF8, “application/json”);

HttpResponseMessage x = await aClient.SendAsync(request);

content =

{“client_id” : “xxxxxxxxxxxxhNWFnGi0RRCCMB92nLd”, “connection” : “Form217” , “grant_type” : “password” ,“scope” : “openid”, “username” : “jsheehan@railcomm.com”, " password" : “xxxxxxxxx”}

Here is a working C# call (using System.Net calls):

HttpClient httpClient = new HttpClient();
var url = "https://tenant.auth0.com/oauth/ro";
var parameters = new Dictionary<string, string>
{
     { "client_id", "CLIENT_ID" },
     { "username", "test@test.com" },
     { "password", "password" },
     { "connection", "Username-Password-Authentication" },
     { "scope", "openid" },
     { "grant_type", "password" }
};
var encodedContent = new FormUrlEncodedContent(parameters);
var response = httpClient.PostAsync(url, encodedContent).Result;

if (response.StatusCode == System.Net.HttpStatusCode.OK)
{
    // Do something with response. Example get content:
    var responseContent = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
}

Unfortunately I can only use System.Net calls.

I am curious why no password is given in this example.How can it authenticate with no password?

Also why not pass application/json and a json formatted string? Its what the documentation shows.

my bad, password is there

This code fails with log below. Someone must have done this with standard C# before.

var uri = “https://railcomm.auth0.com/oauth/ro”;
Uri theUri = new Uri(uri);

        string content = "client_id=xxxxxxxxxxxxxQhNWFnGi0RRCCMB92nLd&connection=Form217,grant_type=password,scope=openid,username=jsheehan%railcomm.com,password=" + passwd + "\"";

        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, uri);


        request.Content = new StringContent(content, System.Text.Encoding.UTF8, "application/x-www-form-urlencoded");

        HttpResponseMessage x = await aClient.SendAsync(request);

        success = x.IsSuccessStatusCode.ToString();

Please see my original answer (I have edited it to use only System.Net calls). Also, if you have any questions or updates, please comment within this post rather than creating a new post.

This looks great, I will try in in 1 hour, thanks for all your efforts

Prashant,
No Luck. This is my routine, it crashes on PostAsync. The user name and password are set to the logoon credentials I use for http://railcomm/auth0.com

string retval = “”;
var url = “https://railcomm.auth0.com/oauth/ro”;

        HttpClient httpClient = new HttpClient();

        var parameters = new Dictionary<string, string>
            {
             { "client_id", "xxxxxxxxxQhNWFnGi0RRCCMB92nLd" },
             { "username", "jsheehan@railcomm.com" },
             { "password", "xxxxxxxxx" },
             { "connection", "Username-Password-Authentication" },
             { "scope", "openid" },
             { "grant_type", "password" }
        };

        var encodedContent = new FormUrlEncodedContent(parameters);

        var response = httpClient.PostAsync(url, encodedContent).Result;

        if (response.StatusCode == System.Net.HttpStatusCode.OK)
        {
            // Do something with response. Example get content:
            var responseContent = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
            retval = response.StatusCode.ToString();

        }//logon
        return retval

BTW, its statuscode = 401 Unauthorized

When I run the following in Postman I get the error at the end.
I pass my own logon credentials … what is it looking for ?

https://railcomm.auth0.com/oauth/ro

{
“client_id”: “xxxxxxxxxyGQhNWFnGi0RRCCMB92nLd”,
“username”: “jsheehan@railcomm.com”,
“password”: “xxxxxxxxx”,
“connection” : “Username-Password-Authentication”,
“grant_type” : “password”,
“scope”: “openid”
}

{
“error”: “invalid_user_password”,
“error_description”: “Wrong email or password.”
}

got it, username is not an email address, both my code and your sample use email addresses

thanks Prashant
