이것을 두 번 실행하세요

query {
  exampleQuery
}

이것을 실행하세요

POST http://localhost:8080/graphql
Content-Type: application/graphql

query {
  exampleQuery
}

두 번째 쿼리는 Authorization 헤더가 설정되지 않았으므로 반드시 실패해야 합니다. JWTAwareContext는 인증 헤더가 없을 때 예외를 던집니다.

그렇게 되지 않으면 HTTP 요청 1을 실행한 다음 HTTP 요청 2를 다시 실행해 보세요.

두 번째 요청이 응답하면:

HTTP/1.1 200 OK
content-type: application/graphql+json; charset=UTF-8
content-length: 34

{
  "data": {
    "exampleQuery": "hello!"
  }
}

디버그 모드에서 SmallRyeGraphQLAbstractHandler에 진입하고 handle 메서드에서 컨텍스트를 종료하세요.

    @Override
    public void handle(final RoutingContext ctx) {

        if (currentManagedContext.isActive()) { // terminate the context here evaluating via debug inspector
            handleWithIdentity(ctx);
        } else {

            currentManagedContext.activate();
            ctx.response()
                    .endHandler(currentManagedContextTerminationHandler)
                    .exceptionHandler(currentManagedContextTerminationHandler)
                    .closeHandler(currentManagedContextTerminationHandler);

            try {
                handleWithIdentity(ctx);
            } catch (Throwable t) {
                currentManagedContext.terminate();
                throw t;
            }
        }
    }

종료 후 응답은 올바른 답(시스템 오류)을 반환합니다.

{
  "errors": [
    {
      "message": "System error",
      "locations": [
        {
          "line": 1,
          "column": 11
        }
      ],
      "path": [
        "exampleQuery"
      ],
      "extensions": {
        "classification": "DataFetchingException"
      }
    }
  ],
  "data": {
    "exampleQuery": null
  }
}

요청 순서 바꾸기

다시 시작한 후 요청 순서를 반대로 하여 요청 2를 두 번, 요청 1을 한 번 실행하면 OK 요청에서 성공 대신 오류가 발생합니다.
