But when I set httpclient's UseDefaultCredentials runtime, it will get an error, of course I know the reason, because this is a server-side function, so I want to ask how to do this scenario

@W2426566602 you may get some help from our Windows auth docs here: https://learn.microsoft.com/aspnet/core/security/authentication/windowsauth?view=aspnetcore-8.0&tabs=visual-studio
As for the UseDefaultCredential flag, it's not supported on the WebAssembly runtime, and hence the exception. We recommend using OIDC instead, where possible.
It looks like this is something many developers have already faced and solved and there are threads on StackOverflow on this topic: https://stackoverflow.com/a/70691831/719967
