I am trying to upload a file to my sharepoint folder using RestAPI but everytime i received status code 403 forbidden. As i am implementing this in dot net core console application so i need to use RestAPI because of "SharePointOnlineCredentials" is no more supported in core. Any help would be much appreciated. Below i pasted my existing code .Thanks !!
byte[] bytefile = System.IO.File.ReadAllBytes("D:/4.txt");
string hostWeb = "https://xxx.sharepoint.com/sites/xxxProjects";
HttpWebRequest endpointRequest = (HttpWebRequest)HttpWebRequest.Create(hostWeb + "/_api/web/GetFolderByServerRelativeUrl('/sites/xxx/Shared%20Documents/Folder1')/Files/add(url='4.txt',overwrite=true)");
endpointRequest.Method = "POST";
endpointRequest.ContentType = "application/json";
endpointRequest.Headers.Add("Authorization", "Bearer " + accessToken);
endpointRequest.GetRequestStream().Write(bytefile, 0, bytefile.Length);
HttpWebResponse endpointresponse = (HttpWebResponse)endpointRequest.GetResponse();
You can use PnP Core to upload files to SharePoint. Check this link on how to do it with PnP Core.

SharePoint CSOM is not supported in .NET Core 5.0, so I'm trying to use HttpWebRequest to upload files to SharePoint 2016 on-premise.
This code sample shown here works in .NET 4.7, however it throws errors when run on .NET Core.
public async Task<string> UploadFile(string folderName, string fileName, byte[] file)
{
// Url to upload file
string resourceUrl = _sharePointUrl + $"/_api/web/GetFolderByServerRelativeUrl('/opportunity/{folderName}')/Files/add(url='{fileName}',overwrite=true)";
HttpWebRequest wreq = HttpWebRequest.Create(resourceUrl) as HttpWebRequest;
wreq.Credentials = _credentials;
wreq.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");
// Get formdigest value from site
wreq.Headers.Add("X-RequestDigest", GetFormDigest());
wreq.Headers.Add("binaryStringRequestBody", "true");
wreq.Method = "POST";
wreq.Accept = "application/json; odata=verbose";
wreq.ContentLength = file.Length;
wreq.Timeout = 100000;
await wreq.GetRequestStream().WriteAsync(file, 0, file.Length);
HttpWebResponse response = (HttpWebResponse)wreq.GetResponse();
return response.StatusDescription;
}
Errors are listed below. The errors are happening on the
HttpWebResponse response = (HttpWebResponse)wreq.GetResponse();
line.
System.AggregateException: 'One or more errors occurred. (An error occurred while sending the request.)'
Inner Exception 1: WebException: An error occurred while sending the request.
Inner Exception 2: HttpRequestException: An error occurred while sending the request.
Inner Exception 3: IOException: The response ended prematurely.
What am I missing?
Does the HttpWebRequest in .NET Core work differently than the .NET framework version?
Do I need to use different headers or configure the request object differently?
Thanks in advance.
I am trying to get WooCommerce data using WooCommerce v3 API from c#.
When I use below url in browser I get the products data as json;
https://MyUsername:MyPassword#mydomain.com/wp-json/wc/v3/products?consumer_key=ck_12345678901234567890&consumer_secret=cs_12345678901234567890
When I use url
https://MyUsername:MyPassword#mydomain.com/wp-json/wc/v3/products
and
consumer_key = ck_12345678901234567890 and consumer_secret = cs_12345678901234567890
as Params in Postman then I get the products data as well. So the credentials and url are valid.
However when I try to do this using HttpWebRequest it fails with "The remote server returned an error: (401) Unauthorized" exception. My code is below and the exception appears on the last line of code.
The vales in HttpWebRequest before the GetResponseAsync call can be seen here.
What am I doing wrong?
Thanks
Regards
string wc_url = "https://MyUsername:MyPassword#mydomain.com/wp-json/wc/v3/products?consumer_key=ck_12345678901234567890&consumer_secret=cs_12345678901234567890";
HttpWebRequest httpWebRequest = null;
httpWebRequest = (HttpWebRequest)WebRequest.Create(wc_url);
httpWebRequest.AllowReadStreamBuffering = false;
WebResponse wr = await httpWebRequest.GetResponseAsync().ConfigureAwait(false);
public async Task<List<Tip>> GetTips()
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://APIURL ");
request.Credentials = CredentialCache.DefaultCredentials;
WebResponse res = await request.GetResponseAsync();
StreamReader sr = new StreamReader(res.GetResponseStream());
string result = sr.ReadToEnd();
List<Tip> tips = JsonConvert.DeserializeObject<List<Tip>>(result);
return tips;

I am working on a project which need to consume an enterprise Web API(Https) and display the data on Win 10 live tile, it’s an UWP application.
But I found it only works when I ran it in IDE(Visual Studio 2015 debug mode) .
When I created a package for this app and run it by powershell for installation, request.GetResponseAsync method throws exception “The login request was denied”.
I tried to check Enterprise Authentication and Private Networks(Client & Server) options in Package.appxmanifest. But there was no effect.
Any idea how to make it work normally? Thanks.
i wanted to use the Google Drive API along with a simple WEB API 2 - Project.
Somehow the GoogleWebAuthorizationBroker.cs is missing.
What i use:
Visual Studio 2013 Update 4
Empty Template with WEB API
My steps:
Creating the empty project including WEB API
building the project
updating packages via Nuget Packager
Install-Package Google.Apis.Drive.v2 (using this guide: https://developers.google.com/drive/web/quickstart/quickstart-cs)
Copy and Paste the code from the above link into a clean api-controller:
public IEnumerable<string> Get()
{
UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
new ClientSecrets
{
ClientId = "228492645857-5599mgcfnhrr74a7er1do1chpam4rnbt.apps.googleusercontent.com",
ClientSecret = "onoyJQaUazQK4VsKUjD63sDu",
},
new[] { DriveService.Scope.Drive },
"user",
CancellationToken.None).Result;
// Create the service.
var service = new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "Drive API Sample",
});
File body = new File();
body.Title = "My document";
body.Description = "A test document";
body.MimeType = "text/plain";
byte[] byteArray = System.IO.File.ReadAllBytes(#"C:\Projects\VS\DataAnime\DataAnime\document.txt");
System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
FilesResource.InsertMediaUpload request = service.Files.Insert(body, stream, "text/plain");
request.Upload();
File file = request.ResponseBody;
return new string[] { file.Id, "value2" };
}
building
6.1 Error: GoogleWebAuthorizationBroker.cs is missing
6.2 Google says following error in browser:
That’s an error.
Error: redirect_uri_mismatch
Application: Project Default Service Account
You can email the developer of this application at: xxxx#gmail.com
The redirect URI in the request: http://example.com:63281/authorize/ did not match a registered
redirect URI.
http://example.com:63281/authorize/ was neither the url i am using for my project nor the url i registered in my developer console (this errorshowing-port is changeing everytime i run this project.
Has anyone an idea why is that?
No other sources helped fixing this weird issue.
I solved it by creating a new project on https://console.developers.google.com for a native software instead of a web-client project, even i am using a web client.
There is just one weird thing:
If i debug my code, it still says that GoogleWebAuthorizationBroker.cs is missing.
Without debugging i can do everything i want.
Thank you very much for your help.
I am totally new to WebApi and WebRequests and other things.
After hours of googling, finally, I managed to do POST using C# and HttpWebRequest.
When I do HttpWebRequest in debug mode using Visual Studio I do not get any exceptions.
My app work as I accept , I get data to webApi server and also get back data.
To be sure how my app communicate with WebApi server I start Fiddler Web Debugger.
During the POST to WebApi, Fiddler chace 401 errors
{"Message":"Authorization has been denied for this request."}
Steping step by step in debuger I fund that following lines of code doing 401 error
HttpWebRequest wr = (HttpWebRequest)WebRequest.Create(url);
wr.Credentials = new NetworkCredential(username, password);
wr.Method = "POST";
wr.ContentType = "application/json";
byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(body);
wr.ContentLength = byteArray.Length;
using (System.IO.Stream dataStream = wr.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length); //After this line of code Fidler Chace HTTP 401
}
Later in code when I do wr.GetResponse() I do get status 200OK.
My questions are :
Do I need to redesign my code to avoid this error in Fiddler ?
Is there other methods to fill HttpWebRequest whit jsonSting beside using GetRequestStream() ?
If your service is enabled with Windows Authentcation, then in Fiddler, you can select the option to automatically authenticate using your logged on credentials by going here:
Composer tab -> Options tab -> Automatically Authenticate
Also, why not use HttpClient from System.Net.Http?...It has a much better and easy programming model...example:
HttpClientHandler handler = new HttpClientHandler();
handler.UseDefaultCredentials = true;
HttpClient client = new HttpClient(handler);
client.BaseAddress = new Uri("http://localhost:9095/");
HttpResponseMessage response = client.PostAsJsonAsync<Customer>("api/values", cust).Result;
