I used the following code. Picture is posted successfully with a name but its not able to post message/description with it. Please tell me where i am wrong. Also its not giving any exception.
private void SharePhoto(string _accessToken, string p)
{
var fb = new FacebookClient(_accessToken);
fb.PostCompleted += (o, args) =>
{
if (args.Error != null)
{
if (args.Error.Message.StartsWith("(OAuthException - #190)"))
{
Dispatcher.BeginInvoke(() =>
{ MessageBox.Show("Message Expired"); });
}
else
{
Dispatcher.BeginInvoke(() =>
{ MessageBox.Show(args.Error.Message, "Error", MessageBoxButton.OK); });
}
return;
}
else
{
Dispatcher.BeginInvoke(() =>
{ MessageBox.Show("Image Posted"); });
}
};
var fbupload = new FacebookMediaObject
{
FileName = "facebook.jpg",
ContentType = "image/jpeg"
};
StreamResourceInfo sri =Application.GetResourceStream(new Uri("facebook.jpg",UriKind.Relative));
BitmapImage bitmap = new BitmapImage();
bitmap.SetSource(sri.Stream);
var loadedImage = new WriteableBitmap(bitmap);
using (MemoryStream ms = new MemoryStream())
{
loadedImage.SaveJpeg(ms, loadedImage.PixelWidth, loadedImage.PixelHeight, 0, 95);
ms.Seek(0, 0);
byte[] data = new byte[ms.Length];
ms.Read(data, 0, data.Length);
ms.Close();
fbupload.SetValue(data);
}
var parameters = new Dictionary<string, object>();
parameters["message"] = txtMessage.Text;
parameters["description"] = "first ever one";
parameters["name"] = "My FB Pic";
parameters["picture"]=fbupload;
parameters["link"] = new Uri(#"http://www.anyxyz.com", UriKind.Absolute);
fb.PostAsync(#"me/photos", parameters);
}
I used extended permissions as:
private const string extendedPermissions = "user_about_me,read_stream,publish_stream";
Any Help would be greatly appreciated.

I have tried the following code ..
When I try out the following code I get 404 content not found. Also my controller doesn't get hit when I try to debug the code ..
public async Task<IActionResult> Download(string filename)
{
if (filename == null)
return Content("filename not present");
var path = Path.Combine(Directory.GetCurrentDirectory(),"wwwroot", filename);
var memory = new MemoryStream();
using (var stream = new FileStream(path, FileMode.Open))
{
await stream.CopyToAsync(memory);
}
memory.Position = 0;
return File(memory, GetContentType(path), Path.GetFileName(path));
}
Upload file with size and filename as response:
public async Task<IActionResult> OnPostUploadAsync(IFormFile file)
{
long size = file.Length;//in bytes
if (file.Length > 0)
{
var name = Path.GetRandomFileName();
//var fileOriginName = file.FileName;
var path = Path.Combine(System.IO.Directory.GetCurrentDirectory(), "wwwroot", name);
using (var stream = System.IO.File.Create(path))
{
await file.CopyToAsync(stream);
}
return Ok(new { size = size, filename = name });
}
else {
return Ok(new { size = 0, filename = ""});
}
}
===============================================
I have an api like below and I had a file test.txt in wwwroot folder.
public async Task<IActionResult> Download(string filename)
{
if (filename == null)
return Content("filename not present");
var path = Path.Combine(System.IO.Directory.GetCurrentDirectory(), "wwwroot", filename);
var memory = new MemoryStream();
using (var stream = new FileStream(path, FileMode.Open))
{
await stream.CopyToAsync(memory);
}
memory.Position = 0;
var contentType = "APPLICATION/octet-stream";
return File(memory, contentType, Path.GetFileName(path));
}
Then when I call localhost:port/home/download?filename=test then I'll get exception that file can't find. And when I call localhost:port/home/Download?filename=test.txt it succeeds.
My API is in an asp.net core MVC project and I think you need to check the contentType.

500 HTTP status code is a generic code which means that the server was not able to process the request due to some issues, First step would be to add some exception handling to your function and see if the failure occurs and where it occurs.
On Side note, you should not use HTTP client in the way used in the code, you should not new it up every time your function executes, this client should be static in nature. Refer Manage connections in Azure Functions
I have this action on my WEBAPI´s controller using .NET that returns bytes from SSRS report link:
public IHttpActionResult GetReport(int? Id)
{
if (Id == null)
{
return NotFound();
}
var reportServer = ConfigurationManager.AppSettings["Report"];
var reportPath = $"{reportServer}/myReport&Id={Id}&rs:Format=PDF";
WebClient Client = new WebClient();
Client.UseDefaultCredentials = true;
byte[] reportBytes = Client.DownloadData(reportPath);
var reportBase64 = Convert.ToBase64String(reportBytes);
return Ok(reportBase64);
}
When i try to generate the PDF from this return, using this react/redux code ( i am using axios)....
//...code
const reportBlob = new Blob([myReportData], { type: "application/pdf" });
const reportBlobUrl = URL.createObjectURL(reportBlob);
window.open(reportBlobUrl);
.....it oppened a new browser´s tab with PDF template BUT showing PDF Error as: 'FAILED TO LOAD PDF document'.
No anwsers anywhere help me resolving this problem. :(
Note: the 'axios' call it´s returning the same array of bytes as the WEBAPI return, so as the 'myReportData' variable.
So i figured out by my self after 4 days. Anyone that needed this functionality (render the SSRS report in PDF within c# code returning PDF bytes from a ASP.NET WEB API, here is the what you have to do within your webapi controller to generate the PDF bytes from report viewer namespace to be sent to your React app using Redux.
WEB API ASP.NET (.NET Framework 4.6 using VS 2019):
note: first option i´ts commented and works the same way the option 2 that i´d prefer.

REACT/REDUX nstrong textote: you have to convert the stream of bytes returned from your WEB API Controller into BLOB format to render it in a new brownser tab in PDF format/type.
a. the button action/behavior
<div className="btn-group-vertical" role="group">

</button>
</div>
b. the component ( i am omiting the redux part (reducers, actions, apiservice...)
openReport(event, item) {
event.preventDefault();
this.props.actions.loadReport(item);
this.setState({ Report: this.props.Report });
const ReportData = this.state.Report;

We have to rework how we're sending emails since we are using Amazon SES. In the past, we were using smtp but can't do that in this case. The class that needs updated has taken in a MailMessage object and used smtp to send it. So I'm trying to rework the method to be able to continue to accept the MailMessage object and convert it to a MimeKit MimeMessage. For the most part it's working fine except when it comes to attachments. In the code I have, the attachment gets added and sent, however, when trying to open it appears it's corrupted or something. In my test case I attached a csv file. I could not open it in excel after receiving the email.
public class EmailAbstraction
{
public virtual void Send(MailMessage mailMessage)
{
sendMessage(mailMessage);
}
private static void sendMessage(MailMessage mailMessage)
{
using (var client = new AmazonSimpleEmailServiceClient(AwsConstants.SESAWSKey, AwsConstants.SESAWSSecret, AwsConstants.RegionEndpoint))
{
foreach (var to in mailMessage.To)
{
using (var messageStream = new MemoryStream())
{
var newMessage = new MimeMessage();
var builder = new BodyBuilder
{
HtmlBody = mailMessage.Body
};
newMessage.From.Add(mailMessage.From == null
? new MailboxAddress(EmailConstants.DefaultFromEmailDisplayName, EmailConstants.DefaultFromEmailAddress)
: new MailboxAddress(mailMessage.From.Address));
newMessage.To.Add(new MailboxAddress(to.DisplayName, to.Address));
newMessage.Subject = mailMessage.Subject;
foreach (var attachment in mailMessage.Attachments)
{
builder.Attachments.Add(attachment.Name, attachment.ContentStream);
}
newMessage.Body = builder.ToMessageBody();
newMessage.WriteTo(messageStream);
var request = new SendRawEmailRequest
{
RawMessage = new RawMessage { Data = messageStream }
};
client.SendRawEmail(request);
}
}
}
}
}
And in my test app, I have this.
internal class Program
{
private static void Main(string[] args)
{
var s = GetFileStream();
var m = new MailMessage();
var sender = new MailAddress("info#ourwebsite.com", "info");
m.From = sender;
m.Sender = sender;
m.Body = "test email";
m.Subject = "test subject";
m.To.Add(myemail);
m.Attachments.Add(new Attachment(s, "test-file.csv"));
new EmailAbstraction().Send(m);
}
private static MemoryStream GetFileStream()
{
var stream = new MemoryStream();
var fileStream = File.Open(#"C:\Users\dev\Desktop\test-file.csv", FileMode.Open);
fileStream.CopyTo(stream);
fileStream.Close();
return stream;
}
}
This is just copied from the MimeKit source code:
static MimePart GetMimePart (System.Net.Mail.AttachmentBase item)
{
var mimeType = item.ContentType.ToString ();
var contentType = ContentType.Parse (mimeType);
var attachment = item as System.Net.Mail.Attachment;
MimePart part;
if (contentType.MediaType.Equals ("text", StringComparison.OrdinalIgnoreCase))
part = new TextPart (contentType);
else
part = new MimePart (contentType);
if (attachment != null) {
var disposition = attachment.ContentDisposition.ToString ();
part.ContentDisposition = ContentDisposition.Parse (disposition);
}
switch (item.TransferEncoding) {
case System.Net.Mime.TransferEncoding.QuotedPrintable:
part.ContentTransferEncoding = ContentEncoding.QuotedPrintable;
break;
case System.Net.Mime.TransferEncoding.Base64:
part.ContentTransferEncoding = ContentEncoding.Base64;
break;
case System.Net.Mime.TransferEncoding.SevenBit:
part.ContentTransferEncoding = ContentEncoding.SevenBit;
break;
//case System.Net.Mime.TransferEncoding.EightBit:
// part.ContentTransferEncoding = ContentEncoding.EightBit;
// break;
}
if (item.ContentId != null)
part.ContentId = item.ContentId;
var stream = new MemoryStream ();
item.ContentStream.CopyTo (stream);
stream.Position = 0;
part.Content = new MimeContent (stream);
return part;
}
