As per this documentation you should be able to create an appRoleAssignment via Microsoft Graph, however this doesn't work. In a GitHub issue I was instructed to create the issue here. We have migrated most of our code from Azure Graph API to Microsoft Graph and this is the last piece that is missing.
This finally worked for me!
There might be more optimized ways to post the JSON but I had to go to basics to make sure nothing is causing this to fail behind the scenes.
const string ROLE_ASSIGNMENT_FORMATTER = "https://graph.microsoft.com/beta/servicePrincipals/{0}/appRoleAssignments";
public static async Task AddApplicationUsers(string enterpriseAppId, string userId, string roleId)
{
HttpClient client = new HttpClient();
string url = string.Format(ROLE_ASSIGNMENT_FORMATTER, enterpriseAppId);
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", await GetAccessToken());
var roleAssignment = new
{
appRoleId = roleId,
principalId = userId,
resourceId = enterpriseAppId
};
var content = new StringContent(Newtonsoft.Json.JsonConvert.SerializeObject(roleAssignment), Encoding.UTF8, "application/json");
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var response = await client.PostAsync(url, content);
if (response.IsSuccessStatusCode)
{
return ;
}
else
{
throw new HttpRequestException(response.ReasonPhrase);
}
}

I'm trying to get the MS example application to work for the Graph Beta Webhooks API and it's currently crashing because I've had to to modify some of the example code to remove some obsolete code and I'm not sure what to replace it with.
This is the function:
public static GraphServiceClient GetAuthenticatedClient(string userId, string redirect)
{
var graphClient = new GraphServiceClient(
new DelegateAuthenticationProvider(
async (request) =>
{
var tokenCache = new SampleTokenCache(userId);
// Obsolete code
//var cca = new ConfidentialClientApplication(Startup.ClientId, redirect, new ClientCredential(Startup.ClientSecret), tokenCache.GetMsalCacheInstance(), null);
// New code
var cca2 = ConfidentialClientApplicationBuilder.Create(Startup.ClientId).WithClientSecret(Startup.ClientSecret).WithRedirectUri(redirect).Build();
// Question - how do I pass the tokenCache in here as the userTokenCache ?
// ERROR - With the new code this returns zero accounts presuambly because I haven't passed in a userTokenCache
var accounts = await cca2.GetAccountsAsync();
// Obsolete code
//var authResult = await cca.AcquireTokenSilentAsync(Startup.Scopes, accounts.First());
// New code
var authResult2 = await cca2.AcquireTokenSilent(Startup.Scopes, accounts.First()).ExecuteAsync();
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", authResult2.AccessToken);
}));
return graphClient;
}
If I use the ConfidentialClientApplicationBuilder then the GetAccountsAsync() returns an empty collection and I think it's because I haven't passed the tokenCache into the builder. Does anyone know how to fix this code or has anyone got the example App working ?
This is the link to the example App:

You need to login as user so that an account is added to the token cache which is available calling the tokenCache.GetMsalCacheInstance() method.
I am using one of the Microsoft Graph API in my project, i.e Outlook mail - "listconferencerooms" api.
Although it is giving he result, but the rooms listed in the result is not as expected.
When I cross check the Api result with the Meeting rooms available in my mailbox, both are not matching. In fact everyday i see the same set of meeting rooms which is not changing as per availability.
Code as below,
[HttpGet]
[Route("api/GetMeetingRooms")]
public async Task<string> getMeetingRooms()
{
//HttpResponseMessage message = null;
try
{
AppConfig appConfig = new AppConfig();
string token = await appConfig.GetTokenForApplication();
string response = string.Empty;
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://graph.microsoft.com/");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage result = client.GetAsync("https://graph.microsoft.com/beta/me/findRooms").Result;
response = result.Content.ReadAsStringAsync().Result;
}
return response;
}
catch (Exception ex)
{
return ex.Message;
}
}
Kindly help me whether I am using correct API to get all available meeting, Conference rooms for my organization?
Or since the API is in Beta version I am not able to get the correct result.
I am attempting to add members to a group. I am able to list all groups in my org, get user by email, get all users and I can even remove a Member from a group but I cannot add one - The error returned is 400 Bad Request.
Here is the function which is the same function signature as those that work: (I do have the accesstoken, valid group id and a valid member id)
I have confirmed the body data looks correct at least as far as I can see from the example in the docs.
Not sure what else I can add to make things clearer, ask and I'll update
public async Task<string> AddGroupMember(string accessToken, string groupId, string memberId)
{
var status = string.Empty;
string endpoint = $"https://graph.microsoft.com/v1.0/groups/{groupId}/members/$ref";
string queryParameter = "";
// pass body data
var keyOdataId = "#odata.id";
var valueODataId = $"https://graph.microsoft.com/v1.0/directoryObjects/{memberId}";
var values = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>(keyOdataId, valueODataId)
};
var body = new FormUrlEncodedContent(values);
try
{
using(var client = new HttpClient())
{
using(var request = new HttpRequestMessage(HttpMethod.Post, endpoint + queryParameter))
{
request.Content = body;
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
using(var response = await client.SendAsync(request))
{
if (response.StatusCode == HttpStatusCode.NoContent)
status = "Member added to Group";
else
status = $"Unable to add Member to Group: {response.StatusCode}";
}
}
}
}
catch (Exception ex)
{
status = $"Error adding Member to Group: {ex.Message}";
}
return status;
}
Thanks for any help that anyone can offer - this is the last call I have to make then home free
Found the issue for any who care to know for the future:
var body = new FormUrl... my code was incorrect, what's needed is a simple json string changed to this UPDATED:
var jsonData = $#"{{ ""{keyOdataId}"": ""{valueODataId}"" }}";
var body = new StringContent(jsonData, Encoding.UTF8, "application/json");
I would normally put the values in a class but this is for proof of concept and the json key needs to look exactly like this #odata.id
Clarifying what is happening here:
The request body for this call should be JSON encoded (application/json). The FormUrlEncodedContent method returns your dictionary as Form encoded (application/x-www-form-urlencoded).
You can write the JSON by hand (like you have so far) but a better solution would be to leverage Json.NET. This will let you encode the dictionary in much the same way you were with FormUrlEncodedContent:
var values = new Dictionary<string, string>
{
{ keyOdataId, valueODataId}
};
var body = JsonConvert.SerializeObject(values);
If you're going to be doing a lot of work with Microsoft Graph, I would highly recommend switching to the Microsoft Graph .NET SDK.
You're method here would be far simpler using the SDK:
public async Task<string> AddGroupMember(string groupId, string memberId)
{
GraphServiceClient graphClient = AuthenticationHelper.GetAuthenticatedClient();
User userToAdd = new User { Id = memberId };
await graphClient.Groups[groupId].Members.References.Request().AddAsync(userToAdd);
}
I am working on a app using gmail api.
I want to perform archive functionality.
I had gone through the api https://developers.google.com/gmail/api but unable to find any desired solutions.
Can anyone suggest me any solution for the same.
Thanks in Advance.
A archived message is just a message that lies in the All Mail (which isn't an actual label). You can achieve this by removing the INBOX-label on the message (or any other label you have added to it), which can be achieved with modify.
C# Code for Gmail APIs Archive email by using OAuth 2.0 service.
class ReadAllMails
{
static string[] Scopes = { GmailService.Scope.MailGoogleCom };
static string ApplicationName = "Gmail API .NET Quickstart";
static void Main(string[] args)
{
UserCredential credential;
using (var stream =
new FileStream("credentials_dev.json", FileMode.Open, FileAccess.Read))
{
string credPath = "token_MailGoogleCom.json";
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
}
var service = new GmailService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName,
});
List<string> lableIds = new List<string>();
lableIds.Add("INBOX");
ModifyMessageRequest mods = new ModifyMessageRequest();
mods.RemoveLabelIds= lableIds;
service.Users.Messages.Modify(mods, "me", emailId).Execute();
//emailId that you want to archive
}
}
I'm building an application in ASP.NET MVC (using C#) and I would like to know how I can perform calls like curl http://www.mywebsite.com/clients_list.xml inside my controller
Basically I would like to build a kind of REST API to perform actions such as show edit and delete, such as Twitter API.
But unfortunately until now I didn't find anything besides that cURL for windows on this website: http://curl.haxx.se/
So I don't know if is there any traditional way to retrieve this kind of call from URL with methods like post delete and put on the requests, etc...
I just would like to know an easy way to perform commands like curl inside my controller on my ASP.NET MVC Application.
UPDATE:
Hi so I managed to make GET Requests but now I'm having a serious problem in retrieve POST Request for example, I'm using the update status API from Twitter that in curl would work like this:
curl -u user:password -d "status=playing with cURL and the Twitter API" http://twitter.com/statuses/update.xml
but on my ASP.NET MVC application I'm doing like this inside my custom function:
string responseText = String.Empty;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://twitter.com/statuses/update.xml");
request.Method = "POST";
request.Credentials = new NetworkCredential("username", "password");
request.Headers.Add("status", "Tweeting from ASP.NET MVC C#");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
responseText = sr.ReadToEnd();
}
return responseText;
Now the problem is that this request is returning 403 Forbidden,
I really don't know why if it works perfectly on curl
:\
UPDATE:
I finally manage to get it working, but probably there's a way to make it cleaner and beautiful, as I'm new on C# I'll need more knowledge to do it, the way the POST params are passed makes me very confused because is a lot of code to just pass params.
Well, I've created a Gist - http://gist.github.com/215900 , so everybody feel free to revise it as you will. Thanks for your help çağdaş
also follow the code here:
public string TwitterCurl()
{
//PREVENT RESPONSE 417 - EXPECTATION FAILED
System.Net.ServicePointManager.Expect100Continue = false;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://twitter.com/statuses/update.xml");
request.Method = "POST";
request.Credentials = new NetworkCredential("twitterUsername", "twitterPassword");
//DECLARE POST PARAMS
string headerVars = String.Format("status={0}", "Tweeting from ASP.NET MVC C#");
request.ContentLength = headerVars.Length;
//SEND INFORMATION
using (StreamWriter streamWriter = new StreamWriter(request.GetRequestStream(), ASCIIEncoding.ASCII))
{
streamWriter.Write(headerVars);
streamWriter.Close();
}
//RETRIEVE RESPONSE
string responseText = String.Empty;
using (StreamReader sr = new StreamReader(request.GetResponse().GetResponseStream()))
{
responseText = sr.ReadToEnd();
}
return responseText;
/*
//I'M NOT SURE WHAT THIS IS FOR
request.Timeout = 500000;
request.ContentType = "application/x-www-form-urlencoded";
request.UserAgent = "Custom Twitter Agent";
#if USE_PROXY
request.Proxy = new WebProxy("http://localhost:3000", false);
#endif
*/
}
Try using Microsoft.Http.HttpClient. This is what your request would look like
var client = new HttpClient();
client.DefaultHeaders.Authorization = Credential.CreateBasic("username","password");
var form = new HttpUrlEncodedForm();
form.Add("status","Test tweet using Microsoft.Http.HttpClient");
var content = form.CreateHttpContent();
var resp = client.Post("http://www.twitter.com/statuses/update.xml", content);
string result = resp.Content.ReadAsString();
You can find this library and its source included in the WCF REST Starter kit Preview 2, however it can be used independently of the rest of the stuff in there.
P.S. I tested this code on my twitter account and it works.
Example code using HttpWebRequest and HttpWebResponse :
public string GetResponseText(string url) {
string responseText = String.Empty;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream())) {
responseText = sr.ReadToEnd();
}
return responseText;
}
To POST data :
public string GetResponseText(string url, string postData) {
string responseText = String.Empty;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.ContentLength = postData.Length;
using (StreamWriter sw = new StreamWriter(request.GetRequestStream())) {
sw.Write(postData);
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream())) {
responseText = sr.ReadToEnd();
}
return responseText;
}
This is the single line of code I use for calls to a RESTful API that returns JSON.
return ((dynamic) JsonConvert.DeserializeObject<ExpandoObject>(
new WebClient().DownloadString(
GetUri(surveyId))
)).data;
Notes
The Uri is generated off stage using the surveyId and credentials
The 'data' property is part of the de-serialized JSON object returned
by the SurveyGizmo API
The Complete Service
public static class SurveyGizmoService
{
public static string UserName { get { return WebConfigurationManager.AppSettings["SurveyGizmo.UserName"]; } }
public static string Password { get { return WebConfigurationManager.AppSettings["SurveyGizmo.Password"]; } }
public static string ApiUri { get { return WebConfigurationManager.AppSettings["SurveyGizmo.ApiUri"]; } }
public static string SurveyId { get { return WebConfigurationManager.AppSettings["SurveyGizmo.Survey"]; } }
public static dynamic GetSurvey(string surveyId = null)
{
return ((dynamic) JsonConvert.DeserializeObject<ExpandoObject>(
new WebClient().DownloadString(
GetUri(surveyId))
)).data;
}
private static Uri GetUri(string surveyId = null)
{
if (surveyId == null) surveyId = SurveyId;
return new UriBuilder(ApiUri)
{
Path = "/head/survey/" + surveyId,
Query = String.Format("user:pass={0}:{1}", UserName, Password)
}.Uri;
}
}
Look into the System.Net.WebClient class. It should offer the functionality you require. For finer grained control, you might find WebRequest to be more useful, but WebClient seems the best fit for your needs.
