Reproduce the issue
Build a function (see code below)
Run mvn clean package azure-functions:run
Call the generated api. The api call will timeout and a stacktrace will be printed.
Code snippet
`public class RunMyHttpTrigger extends AzureSpringBootRequestHandler<HttpRequestMessage, CloseableHttpResponse>
{
@functionName("runMyHttpTrigger")
public HttpResponseMessage run(
@HttpTrigger(name = "req", methods = {HttpMethod.GET, HttpMethod.POST}, authLevel = AuthorizationLevel.ANONYMOUS) HttpRequestMessage request,
final ExecutionContext context) throws IOException
{
context.getLogger().info("Java HTTP trigger processed a request.");
obtainSecuredResource(context);
return request.createResponseBuilder(HttpStatus.BAD_REQUEST).header("Content-Type","application/json").body("Bad Request.").build();
}
public Mono<String> obtainSecuredResource(final ExecutionContext context)
{
final String tokenURI = "https://abc.def.com/oauth/token";
final String clientId = "clientId";
final String clientSecret = "clientSecret";
final String endPointURI = "https://abc.def.com/registration";
context.getLogger().info("=========================================\n");
context.getLogger().info("Access web client...");
Mono<String> resource = WebClient.builder()
.build().post().uri(tokenURI).header(HttpHeaders.AUTHORIZATION, "Basic " + Base64Utils
.encodeToString((clientId + ":" + clientSecret).getBytes())).body(
BodyInserters.fromFormData(OAuth2ParameterNames.GRANT_TYPE, GrantType.CLIENT_CREDENTIALS.getValue())).retrieve()
.onStatus(org.springframework.http.HttpStatus::is4xxClientError, response -> Mono.empty()).bodyToMono(String.class).doOnNext(
System.out::println);
//exception happened this line:
context.getLogger().info("non-blocking Oauth calls registered..." + resource.block());
//resource.block();
//return "test";
return resource.map(res -> "Retrieved the resource using a manual approach: " + res);
}
}`
In pom.xml, I have explicit the dependency about all io.netty with version 4.1.49.Final, and io.grpc with version 1.29.0.
