How to retrieve username, email and image with OneDrive/Graph APIs?

I'm working on a UWP app and I was thinking about moving from the old LiveSDK (which is discontinued and was last updated around 2015) to the new OneDriveSDK (the Graph APIs), specifically using the UWP Community Toolkit Services package and its APIs.
The library seems pretty easy to use as far as login and files/folders management go, but so far I haven't been able to find a way to retrieve the user full name, the user email and the profile picture.
Here's the code I'm currently using to do so, using LiveSDK (code simplified here):
public static async Task<(String username, String email)> GetUserProfileNameAndEmailAsync(LiveConnectSession session)
{
LiveConnectClient connect = new LiveConnectClient(session);
LiveOperationResult operationResult = await connect.GetAsync("me");
IDictionary<String, object> results = operationResult.Result;
String username = results["name"] as String;
if (!(results["emails"] is IDictionary<string, object> emails)) return default;
String email = emails["preferred"] as String ?? emails["account"] as String;
return (username, email);
}
public static async Task<ImageSource> GetUserProfileImageAsync([NotNull] LiveConnectSession session)
{
LiveConnectClient liveClient = new LiveConnectClient(session);
LiveOperationResult operationResult = await liveClient.GetAsync("me/picture");
String url = operationResult.Result?["location"] as String;
// The URL points to the raw image data for the user profile picture, just download it
return default;
}
I've looked at the guide here and I see there seems to be a replacement for all of the above, but I haven't been able to integrate that with the UWP Toolkit service. For example, to retrieve the user info, here's what I've tried:
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "https://graph.microsoft.com/v1.0/me/");
await OneDriveService.Instance.Provider.AuthenticationProvider.AuthenticateRequestAsync(request);
using (HttpResponseMessage response = await OneDriveService.Instance.Provider.HttpProvider.SendAsync(request))
{
String content = await response.Content.ReadAsStringAsync();
}
But this fails with an exception at the SendAsync call.
NOTE: I know there are the Graph APIs too in the UWP Toolkit, with ready-to-use methods to retrieve the user info and profile picture, but apparently you need an office 365 subscription to use those APIs (both as a dev, and probably as a user too), so I guess that's not what I'm looking for here, since I've always been able to retrieve these info using a normal OneDrive client.
Is there a way to do this on UWP, either through some method within the UWP Toolkit, or with some other solution?
Thanks!
EDIT: I've reused the code from the sample app, registered my app to get a clientID and made a quick test, but it's not working as expected and I'm getting this exception:
Fixed, see below
EDIT #2: According to this question, I had to switch to https://graph.microsoft.com/beta to get the profile picture, as the 1.0 version of the APIs doesn't support it for normal MS accounts right now. All things considered, it seems to be working just fine now 👍

I followed the MSDN document to register my app for Microsoft Graph. After that, I will get an application ID(in API, it's called as clientId).
Then, I used the Microsoft Graph Connect Sample for UWP to login in with my general MS account. It worked well. I could get the username, email etc.
Please note that if you want to run this sample successfully, you would need to use the application ID to initialize the PublicClientApplication object in AuthenticationHelper.cs.
public static PublicClientApplication IdentityClientApp = new PublicClientApplication("your client id");

PHP - Upload specified collection of values to a resource identified by specified URI

Just finished an automatic newsletter-subscriber module written in C#. Now I have to translate it in PHP so I can use it with my wordpress sites as well. I'm not that good in PHP as most of the time I'm writting .NET MVC applications. In C# I came up with the following solution:
// Code below runs each time a user submits the newsletter form
using (var client = new WebClient()) {
var MyValues = new NameValueCollection();
MyValues["list"] = "123456789";
MyValues["boolean"] = "true";
MyValues["name"] = model.NameSec;
MyValues["email"] = model.EmailSec;
var MyResponse = client.UploadValues("http://www.XXXXXX.com/subscribe", MyValues);
var MyValue = Encoding.Default.GetString(MyResponse);
if (MyValue.Equals("true")) {
// All correct
}
else {
// Oops, smth went wrong
}
}
Now I'm looking for a similar method as WebClient.UploadValues but for PHP. Could you please give me some guidance?

WebClient.UploadValues() is making a POST request to your URI. To achieve the same in PHP, you should look into Curl. There are plenty of examples available and a number of questions that already address the topic.
This is probably the best answer with source code/examples.

Facebook Retrive Data using Graph API using c#

i have created desktop Facebook application using c# .net. i want to retrieve users message,post and chat history. which is convenient way to retrieve users all information.i have started with Facebook Graph API but i am not getting any example.
can any one help me ?

A bit late to the party but anyway:
Add a reference to System.Net.Http and Newtonsoft.Json
string userToken = "theusertokentogiveyoumagicalpowers";
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://graph.facebook.com");
HttpResponseMessage response = client.GetAsync($"me?fields=name,email&access_token={userToken}").Result;
response.EnsureSuccessStatusCode();
string result = response.Content.ReadAsStringAsync().Result;
var jsonRes = JsonConvert.DeserializeObject<dynamic>(result);
var email = jsonRes["email"].ToString();
}

Go to developer.facebook.com -> Tools & Support -> Select Graph API Explorer
Here U get FQL Query, Access Token
Then write code in C#.....
var client = new FacebookClient();
client.AccessToken = Your Access Token;
//show user's profile picture
dynamic me = client.Get("me?fields=picture");
pictureBoxProfile.Load(me.picture.data.url);
//show user's birthday
me = client.Get("me/?fields=birthday");
labelBirthday.Text = Convert.ToString(me.birthday);

I hope this will help you.!!!

you can check the Graph explorer tool on Developer.facebook.com , go to Tools and select graph explorer, its a nice tool which gives you exact idea about what you can fetch by sending "GET" and "POST" method on FB Graph APis

From what i see the app now only uses webhooks to post data to a data endpoint (in your app) at which point you can parse and use this. (FQL is deprecated). This is used for things like messaging.
A get request can be send to the API to get info - like the amt. of likes on your page.
The docs of FB explain the string you have to send pretty nicely. Sending requests can be done with the webclient, or your own webrequests.
https://msdn.microsoft.com/en-us/library/bay1b5dh(v=vs.110).aspx
Then once you have a string of the JSON formatted page you can parse this using JSON.NET library. It's available as a NUGEt package.

Authenticate user with twitter login

I wonder of someone know a working sample of logging in using Twitter (OAuth) for .NET
I'm currently using this one http://www.voiceoftech.com/swhitley/?p=681
but it only works if I set the callback url to "oob", if I set a real callback url I get "401 unauthorized".
Thanks!

I wrote an OAuth manager for this, because the existing options were too complicated.
OAuth with Verification in .NET
The class focuses on OAuth, and works specifically with Twitter. This is not a class that exposes a ton of methods for the entire surface of Twitter's web API. It is just OAuth. If you want to update status on Twitter, this class exposes no "UpdateStatus" method. I figured it's a simple matter for app designers to construct the HTTP message they want to send. In other words the HTTP message is the API. But the OAuth stuff can get a little complicated, so that deserves an API, which is what the OAuth class is.
Here's example code to request a "request token":
var oauth = new OAuth.Manager();
oauth["consumer_key"] = MY_APP_SPECIFIC_CONSUMER_KEY;
oauth["consumer_secret"] = MY_APP_SPECIFIC_CONSUMER_SECRET;
oauth.AcquireRequestToken(SERVICE_SPECIFIC_REQUEST_TOKEN_URL, "POST");
THAT'S IT. In Twitter, the service-specific URL for requesting tokens is "https://api.twitter.com/oauth/request_token".
Once you get the request token, you pop the web browser UI in which the user will explicitly grant approval to your app, to access Twitter. You need to do this once, the first time the app runs. Do this in an embedded WebBrowser control, with code like so:
var url = SERVICE_SPECIFIC_AUTHORIZE_URL_STUB + oauth["token"];
webBrowser1.Url = new Uri(url);
For Twitter, the URL for this is "https://api.twitter.com/oauth/authorize?oauth_token=" with the oauth_token appended.
Grab the pin from the web browser UI, via some HTML screen scraping. Then request an "access token":
oauth.AcquireAccessToken(URL_ACCESS_TOKEN,
"POST",
pin);
For Twitter, that URL is "https://api.twitter.com/oauth/access_token".
You don't need to explicitly handle the access token; the OAuthManager class maintains it in state for you. But the token and secret are available in oauth["token"] and oauth["token_secret"], in case you want to write them off to permanent storage. To make requests with that access token, generate the authz header like this:
var authzHeader = oauth.GenerateAuthzHeader(url, "POST");
...where url is the resource endpoint. To update the user's status on Twitter, it would be "http://api.twitter.com/1/statuses/update.xml?status=Hello".
Then set the resulting string into the HTTP Header named Authorization, and send out the HTTP request to the url.
In subsequent runs, when you already have the access token and secret, you can instantiate the OAuth.Manager like this:
var oauth = new OAuth.Manager();
oauth["consumer_key"] = MY_APP_SPECIFIC_CONSUMER_KEY;
oauth["consumer_secret"] = MY_APP_SPECIFIC_CONSUMER_SECRET;
oauth["token"] = your_stored_access_token;
oauth["token_secret"] = your_stored_access_secret;
Then just generate the authz header, and make your requests as described above.

Already solved my issue with http://www.voiceoftech.com/swhitley/?p=681
I was saving my app as "browser" but since I wasn't especifying a callback url it was transformed to "client" app on saving.

I am late to the conversation, but I have created a video tutorial for anyone else who is having this same task. Like you, I had a ton of fun figuring out the 401 error.

"DotNetOpenAuth" will be great helps for u. http://www.dotnetopenauth.net/

I've developed a C# library for OAuth that is really simple to use and get up and running with. The project is an open source project and I've included a demo application that works against
1. Google
2. Twitter
3. Yahoo
4. Vimeo
Of course any other OAuth provider will do as well. You can find the article and library here

Google Charts of SSL

I need to get the free Google charts working over SSL without any security errors. I am using c# and asp.net.
As Google charts does not support SSL by default, I am looking for a robust method of using there charts but ensuring my user doesn't get any security warnings over their browser.
One thought was to use a handler to call the charts api and then generate the output my site needs.
Similar to Pants are optional blog post. I haven't been able to get this example working at this stage.
Any suggestions, or samples are welcome.
Thanks

the Google Charts API is now available over HTTPS at via https at chart.googleapis.com.
Source: http://www.imperialviolet.org/2010/11/29/charthttps.html

We do this automatically in the NetQuarry Platform - it's pretty simple, although you do force the image to come through your site vs. charts.google.com, making your browser run the request through a single connection.
Since a chart is just a link to an image, what we do is to build the link to the chart (a much more complex process, obviously), then add the whole link to the query string on an internal handler (handler.ashx?req=chart& ). So the new link looks like this:
handler.ashx?act=chrt&req=chart&cht=p3&chs=450x170&chd=s:HAR9GBA&chl=New|In%20Progress|Responded|Won't%20Respond|On%20Hold|Future|Review|&chg=20,20,1,5&chg=10,25,1,5&chco=0A477D
Then, we simply download the image data and write it back as the response.
Here's the code:
Blockquote
private void GoogleChart(HttpContext cxt)
{
const string csPrefix = "?act=chrt&req=chart&";
HttpRequest req = cxt.Request;
HttpResponse rsp = cxt.Response;
string sUrl = cxt.Request.RawUrl;
int nStart = sUrl.IndexOf(csPrefix, StringComparison.OrdinalIgnoreCase);
rsp.Clear();
if (nStart > 0)
{
sUrl = "http://chart.apis.google.com/chart?" + sUrl.Substring(nStart + csPrefix.Length);
System.Net.WebClient wc = new System.Net.WebClient();
byte[] buffer = wc.DownloadData(sUrl);
cxt.Response.ClearContent();
cxt.Response.ClearHeaders();
cxt.Response.ContentType = "application/octet-stream";
cxt.Response.AppendHeader("content-length", buffer.Length.ToString());
cxt.Response.BinaryWrite(buffer);
}
}

I Have a partial solution that has one issue.
