Support passing headers to RequestExecutor via graphQLClient.executeQuery()

[rachanamamillapalli]

Currently the graphQLClient.executeQuery method only accepts passing query, variables, operation name, request Executor.
Is there a way we could pass custom headers down to request executor?

Yes you can pass custom headers to request executor. You can use below code where in you can pass requestHeaders as method parameters:

  private RequestExecutor createRestTemplateRequestExecutor(HttpHeaders requestHeaders){
       return (url, headers, body) -> {
           requestHeaders.putAll(headers);
           ResponseEntity<String> exchange = restTemplate.exchange(url, HttpMethod.POST, new HttpEntity<>(body, requestHeaders), String.class);
           return new HttpResponse(exchange.getStatusCodeValue(), exchange.getBody());
       };

The answer above is correct for using the RequestExecutor.

We now also have a WebClientGraphQLClient. When using that you can provide headers as follows:

WebClient webClient = WebClient.create("http://localhost:8080/graphql");
WebClientGraphQLClient client = MonoGraphQLClient.createWithWebClient(webClient, headers -> headers.add("myheader", "test"));

client.reactiveExecuteQuery("...");

Hi @paulbakker ,

Wanted to know are we suppose to create WebClientGraphQLClient for each request. As i have a use-case where header is being generated from a variable which changes for every request.

We wants to keep WebClientGraphQLClient singleton but challenge is with passing dynamic variable at runtime while executing query

@paulbakker @berngp @srinivasankavitha Any timeline on when the release candidate would be available for consumption?

[berngp]

There is already a https://github.com/Netflix/dgs-framework/releases/tag/v4.9.0-rc.1

[rachanamamillapalli]

@berngp Its tagged pre-release. I don't think it's available yet?

[rachanamamillapalli]

@paulbakker @berngp Sorry for the multiple threads, but would it be possible to release the new version today or provide an ETA? 😅
I want to avoid the re-work of using deprecated features if possible.

[paulbakker]

We just released 4.9.0. It might take a couple of hours before Maven central is synced.

[rachanamamillapalli]

Thanks a bunch. Its in sync now
