Listing app service certificates fails #670

Open nilscodes opened 5 years ago

nilscodes commented 5 years ago

I have the following code that tries to list existing app service certificates (3rd party) via the REST API:

Optional<AppServiceCertificate> existingAppCert = azure.appServices().certificates().list().stream().filter(c -> c.thumbprint().equalsIgnoreCase(MY_THUMBPRINT)).findFirst();

This code errors out because the REST API as documented here https://docs.microsoft.com/en-us/rest/api/appservice/certificates/list returns a plain list of certificates, while the list() call is expecting a PagedList<>.

As is, this API is not usable for me via the Java SDK :(

The exception is as follows:

@npeuser The operation returns a (CertificateCollection)[https://docs.microsoft.com/en-us/rest/api/appservice/certificates/list#response]... which has a next page link...

The API is paginated. Fluent Java SDK API for listing certificates in turn returns a paged list.

What is the version of the SDK that you are using?
