Somebody can explain me this code :
auth = new MvcAuthorizer
{
Credentials = credentials
};
auth.CompleteAuthorization(Request.Url);
var auth = new MvcAuthorizer
{
Credentials = new SessionStateCredentials()
{
ConsumerKey = this.client.ConsumerKey,
ConsumerSecret = this.client.ConsumerSecret,
OAuthToken = identity.Token.Token
}
};
the difference between the two codes
Thanks,
Logically, there is no difference. I'm making the assumption that "credentials" in the first example is a SessionStateCredentials that was instantiated previously in the code. The second example uses object initialization syntax to do the same thing.

"I'm using the JWT library in a Spring-based Java application and I'm facing an error "io.jsonwebtoken.ExpiredJwtException: JWT expired at 2023-02-09T12:31:06Z. Current time: 2023-02-13T09:29:07Z, a difference of 334681633 milliseconds. Allowed clock skew: 0 milliseconds.".
I tried to generate a JWT token using the code below, but I am getting an "Expired Jwt Exception".
Here's my code:
private String generateToken(Map<String, Object> extractClaims, UserDetails userDetails) {
return Jwts.builder()
.setClaims(extractClaims)
.setSubject(userDetails.getUsername())
.setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis()+1000 *60 *30))
.signWith(getSignKey(), SignatureAlgorithm.HS256)
.compact();
}

Sorry for my poor language. I would like to know how to get the token after logging in in xamarin.forms. I enter my email and password in postman, it generates the token visible at the bottom
I authorize myself by entering Bearer + token
You can use HttpClient to Consume a RESTful Web Service and get the token from the response:
public async void test() {
var client = new HttpClient();
string jsonData = #"{""username"" : ""myusername"", ""password"" : ""mypassword""}";
var content = new StringContent(jsonData, Encoding.UTF8, "application/json");
HttpResponseMessage response = await client.PostAsync("your request url", content);
// this result string should be something like: "{"token":"rgh2ghgdsfds"}"
var result = await response.Content.ReadAsStringAsync();
Console.WriteLine(result);
}

I am using spring webflux functional style.
I want to create a endpoint which accepts large image files and send this files to another service with webClient in streaming way.
All file processing should be in streaming way because I don't want to my app crush because of outofmemory.
Is there anyway to do this ?
Probably something like this:
#PostMapping(value = "/images/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public Mono<ResponseEntity<Void>> uploadImages(#RequestPart("files") Flux<FilePart> fileParts) {
return fileParts
.flatMap(filePart -> {
return webClient.post()
.uri("/someOtherService")
.body(BodyInserters.fromPublisher(filePart.content(), DataBuffer.class))
.exchange()
.flatMap(clientResponse -> {
//some logging
return Mono.empty();
});
})
.collectList()
.flatMap(response -> Mono.just(ResponseEntity.accepted().build()));
}
This accepts MULTIPART FORM DATA where you can attach multiple image files and upload them to another service.

I have a pdf file in my server and i want a method to download the pdf file and extract images from that file. So far i have used XamiTextSharpLGPLv2, pdfbox but no luck so far.
PdfReader reader = new PdfReader(new Uri(url));
for (int i = 1; i <= reader.NumberOfPages; i++)
{
PdfDictionary pg = reader.GetPageN(i);
iTextSharp.text.pdf.PdfObject PDFObj = reader.GetPdfObject(i);
if ((PDFObj != null) && PDFObj.IsStream())
{
iTextSharp.text.pdf.PdfStream PDFStremObj = (iTextSharp.text.pdf.PdfStream)PDFObj;
try
{
//var pdfImage = new PdfImageObject((PRStream)PDFStremObj);
//var img = pdfImage.GetDrawingImage();
}
catch (Exception)
{
}
}
}
PdfImageObject is not found in XamiTextSharpLGPLv2,
how can i use XamiTextSharpLGPLv2 to extract images or suggestions for any other library to achieve this would be a great help.

I am about to start writing a program that will have a GUI interface with the user that prompts for a number between 1-100. The program then emails me that number(this program would be running on an unknown users computer).
I am unable to decide what programing language to use for such a project. Can anyone suggest a language that is able to do GUI, and send emails from someone elses computer? (Preferable be able to save this program as a .exe or some single file that can be run from their computer. Also would prefer a link as to how to email in that language, but I am fine doing that research myself, just unsure what language to start researching in. If I left anything out please leave a comment asking for clarification. Thanks for any help I can get.
Use C# cus you know it's awesome (heavily biased answer) and here's the code
private bool sendMsg (string from, string to, string subject , string messageBody)
{
MailMessage message = null;
try
{
message = new MailMessage(from, to);
using (message) {
message.Subject = subject;
//message.CC.Add(CCemailAddress);
message.Body = messageBody;
message.IsBodyHtml = false;
SmtpClient client = new SmtpClient("smtp.outlook.com", 587);
client.Credentials = new System.Net.NetworkCredential(from, "Sending Accounts Password");
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = true; //enable SSL
client.Send(message);
client.Dispose();
}
}
catch
{
return false;
}
message.Dispose();
return true;
}
