"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.

Are there any best practices for documenting possible error codes returned from a Web API call? I'm referring to custom logic errors as opposed to standard HTTP return codes.
For example, consider an API method to allow a user to change their password. A possible error condition might be that the new password provided has already been used by that user previously (ie, password history requirement). You could use the following code to communicate that to the caller:
public HttpResponseMessage ChangePassword(string oldPassword, string newPassword)
{
try
{
passwordService.ChangePassword(oldPassword, newPassword)
return Request.CreateResponse(HttpStatusCode.OK);
}
catch (Exception ex)
{
switch(ex.Message)
{
case "PasswordHistoryFailed":
return Request.CreateResponse(HttpStatusCode.BadRequest, new CustomErrorClass("FailedHistoryRequirements"));
break;
...
}
}
}
In this example, I'm using a custom error class to wrap a custom error code of "FailedHistoryRequirements". I could have more error codes for this operation such as too many password changes in a 24 hour period or whatever.
I want to know if there's an accepted way to automatically document these custom error codes in the method's XML Code Comments so that it can be consumed by a documentation generator like Swashbuckle/Swagger or something similar.
If you use Swagger, you can use the SwaggerResponse attribute.
Check out this blog post:
https://mattfrear.com/2015/04/21/generating-swagger-example-responses-with-swashbuckle/
I do this by catching a specific exception type, rather than parsing the message.
Here I have MyDepartmentCentricBaseException as a custom exception. I may have 2-3 exceptions that derive from it. But by using a base-exception, I keep my exception catching cleaner.
try
{
/* do something */
}
catch (MyDepartmentCentricBaseException deptEx)
{
HttpResponseException hrex = this.GetDepartmentMissingHttpResponseException(deptEx.DepartmentSurrogateKey);
throw hrex;
}
catch (Exception ex)
{
/* log it somewhere !*/
throw new HttpResponseException(HttpStatusCode.InternalServerError);
}
private HttpResponseException GetDepartmentMissingHttpResponseException(int DepartmentSurrogateKey)
{
HttpResponseMessage resp = new HttpResponseMessage(HttpStatusCode.NotFound)
{
Content = new StringContent(string.Format("No Department with DepartmentSurrogateKey = {0}", DepartmentSurrogateKey)),
ReasonPhrase = "DepartmentSurrogateKey Not Found"
};
HttpResponseException returnEx = new HttpResponseException(resp);
return returnEx;
}
There are other ideas here:
https://learn.microsoft.com/en-us/aspnet/web-api/overview/error-handling/exception-handling
But I don't know of a way of auto-voodoo-it with documentation. :(

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.
