将标题添加到graphql响应

Question

I'm building a graphql server with Spring and graphql-spring-boot-starter. To solve a very specific issue, I'd like to add a HTTP header to the graphql HTTP response.

How can I achieve that?

Answer 1

You can add the add the headers in ResponseEntity.

public ResponseEntity<Object> callGraphQLService(@RequestBody String query) {

        ExecutionInput input = ExecutionInput.newExecutionInput()
                .query(query)
                .build();
        ExecutionResult result = graphService.getGraphQL().execute(input);
        HttpHeaders headers = new HttpHeaders();
        headers.add("Response-Code", "ABCD");
        return new ResponseEntity<>(result, headers, HttpStatus.OK);
    }
