Could you help me with RingCentral Fax API. I need C# code to download attachments sent via Fax. I'm using sandbox account and I found this API in API Explorer:
/restapi/v1.0/account/{accountId}/extension/{extensionId}/message-store/{messageId}/content/{attachmentId}
Using the RingCentral C-Sharp SDK you can download the binary content as shown below:
RestClient rc = new RestClient("ClientID", "ClientSecret", false);
await rc.Authorize("username", "extensionNumber", "password");
...
var extension = rc.Restapi().Account().Extension();
var messages = response.records;
// fax
var message = messages.Where(m => m.type == "Fax" && m.messageStatus != "SendingFailed" && m.attachments != null && m.attachments.Length > 0).Skip(3).First();
var content = await extension.MessageStore(message.id).Content(message.attachments[0].id).Get();
System.IO.File.WriteAllBytes("filename.ext", content.data);
See detailed sample code from here
You can Download using WebClient Class.
Sample Code For Your Reference.
Code:
WebClient client = new WebClient();
client.Headers.Add("Authorization", "Bearer Access_Token");
File.WriteAllBytes(#"Path To Download", client.DownloadData(URL));
Note: URL is restapi/v1.0/account/AccountID/extension/extension ID/message-store/Message ID/content/Message ID

I'm looking for a way to convert Office files to PDF.
I found out that Microsoft Graph could be used.
I'm trying to download converted PDF using Microsoft Graph from OneDrive.
I'd like to convert .docx to .pdf.
However, when I sent the following request, I did not receive a response even if I waited.
GET https://graph.microsoft.com/v1.0/users/{id}/drive/root:/test.docx:/content?format=pdf
Also, the error code is not returned.
If syntax is wrong, an error code will be returned as expected.
It will not return only when it is correct.
In addition, I can download the file if I do not convert.
GET https://graph.microsoft.com/v1.0/users/{id}/drive/root:/test.docx:/content
Is my method wrong or else I need conditions?
If possible, please give me sample code that you can actually do.
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
client.BaseAddress = new Uri(graphUrl);
var result = await client.GetAsync("/v1.0/users/xxxxxxxxxxxxxxxxxxxxxxxxx/drive/root:/test.docx:/content?format=pdf");
:
I would like to elaborate a bit Marc's answer by providing a few examples for HttpClient.
Since by default for HttpClient HttpClientHandler.AllowAutoRedirect property is set to True there is no need to explicitly follow HTTP redirection headers and the content could be downloaded like this:
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
client.BaseAddress = new Uri("https://graph.microsoft.com");
var response = await client.GetAsync($"/v1.0/drives/{driveId}/root:/{filePath}:/content?format=pdf");
//save content into file
using (var file = System.IO.File.Create(fileName))
{
var stream = await response.Content.ReadAsStreamAsync();
await stream.CopyToAsync(file);
}
}
In case if follow HTTP redirection is disabled, to download the converted file, your app must follow the Location header in the response as demonstrated below:
var handler = new HttpClientHandler()
{
AllowAutoRedirect = false
};
using (HttpClient client = new HttpClient(handler))
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
client.BaseAddress = new Uri("https://graph.microsoft.com");
var response = await client.GetAsync($"/v1.0/drives/{driveId}/root:/{filePath}:/content?format=pdf");
if(response.StatusCode == HttpStatusCode.Redirect)
{
response = await client.GetAsync(response.Headers.Location); //get the actual content
}
//save content into file
using (var file = System.IO.File.Create(fileName))
{
var stream = await response.Content.ReadAsStreamAsync();
await stream.CopyToAsync(file);
}
}
The API doesn't return the converted content directly, it returns a link to the converted file. From the documentation:
Returns a 302 Found response redirecting to a pre-authenticated download URL for the converted file.
To download the converted file, your app must follow the Location header in the response.
Pre-authenticated URLs are only valid for a short period of time (a few minutes) and do not require an Authorization header to access.
You need to capture the 302 and make a 2nd call to the URI in the Location header in order to download the converted file.
Hello Office / SharePoint Developers,
I am working on a project based on the Office Developer Patterns and Practices Sample where a console application accesses a WebAPI which then access SharePoint Online as the logged in user: The sample is here: https://github.com/SharePoint/PnP/tree/master/Samples/AzureAD.WebAPI.SPOnline
Question:
When I attempt to upload a file to the document library, I get an error 401 "The remote server returned an error: (401) Unauthorized".
The file read options such as listing the documents and querying for documents works fine.
The user credentials I supply are of a user that is the site collection admin, owner, and global admin on the tenant.
I get an access token from SharePoint online based on the token I get in the native client.
public string GetAccessToken(string accessToken)
{
string clientID = _clientId;
string clientSecret = _clientSecret;
var appCred = new ClientCredential(clientID, clientSecret);
var authContext = new Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext("https://login.windows.net/common");
AuthenticationResult authResult = authContext.AcquireToken(new Uri(_spoUrl).GetLeftPart(UriPartial.Authority), appCred, new UserAssertion(accessToken));
return authResult.AccessToken;
}
This is the CSOM that uploads the file. I know it works as I can paste it into a console app and using (SharePointOnlineCredentails) it works fine.
string newToken = _tokenSvc.GetAccessToken(accessToken);
using (ClientContext cli = new ClientContext(_spoUrl))
{
cli.ExecutingWebRequest += (s, e) => e.WebRequestExecutor.WebRequest.Headers.Add("Authorization", "Bearer " + newToken);
cli.AuthenticationMode = ClientAuthenticationMode.Default;
using (var fs = new FileStream(#"c:\test.txt", FileMode.Open))
{
var fi = new FileInfo("test.txt");
var list = cli.Web.Lists.GetByTitle("documents");
cli.Load(list.RootFolder);
cli.ExecuteQuery();
var fileUrl = String.Format("{0}/{1}", list.RootFolder.ServerRelativeUrl, fi.Name);
Microsoft.SharePoint.Client.File.SaveBinaryDirect(cli, fileUrl, fs, true);
Web web = cli.Web;
Microsoft.SharePoint.Client.File newFile = web.GetFileByServerRelativeUrl(fileUrl);
cli.Load(newFile);
cli.ExecuteQuery();
ListItem item = newFile.ListItemAllFields;
item["CRUID"] = "CRU_1337";
item.Update();
cli.ExecuteQuery();
}
}...
TLDR: I get 401 on file upload. Reads work. I am using CSOM with an access token that is supposed to be a webAPI on behalf of the logged in user.
I look forward to hearing your advice!
Chris
I am not sure whether we could upload/download files from SP using access tokens with CSOM now , see discussion here two years ago . But we could use sharepoint online rest api to upload files to sharepoint online , i tried below code and it works fine in the code sample AzureAD.WebAPI.SPOnline :
string sharePointUrl = ConfigurationManager.AppSettings["SharePointURL"];
string newToken = GetSharePointAccessToken(sharePointUrl, this.Request.Headers.Authorization.Parameter);
using (ClientContext cli = new ClientContext(sharePointUrl))
{
cli.AuthenticationMode = ClientAuthenticationMode.Default;
cli.ExecutingWebRequest += (s, e) => e.WebRequestExecutor.WebRequest.Headers.Add("Authorization", "Bearer " + newToken);
cli.AuthenticationMode = ClientAuthenticationMode.Default;
byte[] bytefile = System.IO.File.ReadAllBytes(#"e:\log.txt");
HttpWebRequest endpointRequest = (HttpWebRequest)HttpWebRequest.Create("https://xxx.sharepoint.com/sites/xxx/" + "/_api/web/GetFolderByServerRelativeUrl('Shared%20Documents')/Files/add(url='log.txt',overwrite=true)");
endpointRequest.Method = "POST";
endpointRequest.Headers.Add("binaryStringRequestBody", "true");
endpointRequest.Headers.Add("Authorization", "Bearer " + newToken);
endpointRequest.GetRequestStream().Write(bytefile, 0, bytefile.Length);
HttpWebResponse endpointresponse = (HttpWebResponse)endpointRequest.GetResponse();
}
The code below is ended up being the solution to my question:
/* Beginning CSOM Magic */
using (ClientContext cli = new ClientContext(_spoUrl))
{
/* Adding authorization header */
cli.ExecutingWebRequest += (s, e) => e.WebRequestExecutor.WebRequest.Headers.Add("Authorization", "Bearer " + newToken);
cli.AuthenticationMode = ClientAuthenticationMode.Default;
//Get Document List
List documentsList = cli.Web.Lists.GetByTitle(_libraryName);
var fileCreationInformation = new FileCreationInformation();
//Assign to content byte[] i.e. documentStream
var data = System.IO.File.ReadAllBytes(#"c:\test.txt");
fileCreationInformation.Content = data;
//Allow owerwrite of document
fileCreationInformation.Overwrite = true;
//var siteURL = _spoUrl;
var documentListURL = "shared documents";
//var documentName = "/test.txt";
//Upload URL
fileCreationInformation.Url = string.Concat(_spoUrl,"/",documentListURL,"/",documentName);
Microsoft.SharePoint.Client.File uploadFile = documentsList.RootFolder.Files.Add(
fileCreationInformation);
//Update the metadata for a field having name "DocType"
uploadFile.ListItemAllFields["CRUID"] = cruId;
uploadFile.ListItemAllFields.Update();
cli.ExecuteQuery();
}
I'm trying to get an AppOnly access token for use in the Authorization Bearer header of my request to a REST endpoint in Project Online (SharePoint). Following is a snippet of the code that I was using to retrieve the access token.
private OAuth2AccessTokenResponse GetAccessTokenResponse()
{
var realm = TokenHelper.GetRealmFromTargetUrl([[our_site_url]]);
var resource = $"00000003-0000-0ff1-ce00-000000000000/[[our_site_authority]]#{realm}";
var formattedClientId = $"{ClientId}#{realm}";
var oauth2Request = OAuth2MessageFactory.CreateAccessTokenRequestWithClientCredentials(
formattedClientId,
ClientSecret,
resource);
oauth2Request.Resource = resource;
try
{
var client = new OAuth2S2SClient();
var stsUrl = TokenHelper.AcsMetadataParser.GetStsUrl(realm);
var response = client.Issue(stsUrl, oauth2Request) as OAuth2AccessTokenResponse;
var accessToken = response.AccessToken;
}
catch (WebException wex)
{
using (var sr = new StreamReader(wex.Response.GetResponseStream()))
{
var responseText = sr.ReadToEnd();
throw new WebException(wex.Message + " - " + responseText, wex);
}
}
}
I keep getting 403 Forbidden as the response from the server, even if I include site collection admin credentials with my request. Does anyone out there have any ideas?
After creating a support ticket with Microsoft to figure this out we eventually decided to move away from using app permissions for console application authorization.
Our workaround was to create SharePointOnlineCredentials object using a service account, and then get the Auth cookie from the credentials object to pass with our WebRequest. This solution came from scripts found here: https://github.com/OfficeDev/Project-REST-Basic-Operations
I am working on a Microsoft Bot Framework project to add a chatbot to my website.
I need to pass data continuously from the chat UI to the Bot to get user details and current page details. Therefore I cannot use the Web Chat client.
What other methods can I use apart from creating my own chat interface ?
What other methods can I use apart from creating my own chat interface ? According to this statement, WebChat is the easiest way. Because only with an embeded Iframe you are done creating your chatbot. Apart from that,
There is a REST Api to access the botframework. It is called as Direct Line API. You can find documentation from,
HERE
Below is a code sample about how you can use it. I tried with the ASP.NET MVC application.
private async Task<bool> PostMessage(string message)
{
bool IsReplyReceived = false;
client = new HttpClient();
client.BaseAddress = new Uri("https://directline.botframework.com/api/conversations/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("BotConnector", "[YourAccessToken]");
response = await client.GetAsync("/api/tokens/");
if (response.IsSuccessStatusCode)
{
var conversation = new Conversation();
response = await client.PostAsJsonAsync("/api/conversations/", conversation);
if (response.IsSuccessStatusCode)
{
Conversation ConversationInfo = response.Content.ReadAsAsync(typeof(Conversation)).Result as Conversation;
string conversationUrl = ConversationInfo.conversationId+"/messages/";
BotDirectLineApproch.Models.Message msg = new BotDirectLineApproch.Models.Message() { text = message };
response = await client.PostAsJsonAsync(conversationUrl,msg);
if (response.IsSuccessStatusCode)
{
response = await client.GetAsync(conversationUrl);
if (response.IsSuccessStatusCode)
{
MessageSet BotMessage = response.Content.ReadAsAsync(typeof(MessageSet)).Result as MessageSet;
ViewBag.Messages = BotMessage;
IsReplyReceived = true;
}
}
}
}
return IsReplyReceived;
}
In here Message, MessageSet and Conversation are classes created by looking at the Json response in the documentation. If you need, I can add that also.
Cheers!
i want of find location based on current URL request for my project.
eg. if a user log in , system should output local area -> City -> country
from google API and also show the locaton and google map.
I have worked with freegeoip and to get the geo location from this is as below.
URL:- http://freegeoip.net/xml/{ip}
In this you can provide your IP and can see result in browser.
Implementation in code.
string apiUrl = http://freegeoip.net/xml/{ip}
HttpClient HttpClient = new HttpClient();
var response = HttpClient.GetAsync(apiUrl).Result;
if (response != null && response.ReasonPhrase != "Unauthorized")
{
var myobject = response.Content.ReadAsStringAsync();
}
