I looked around but it seems as if there is no suitable solution for a problem I am not alone with: Why am I not able to add attributes to a WebClient (or WebTestClient respectively) request? Whenever I try something like:
var respSpec = webTestClient.post()
.uri("http://localhost:10080" "/endpoint")
.header(apiSecretHeader, secret)
.header("HEADER_1", "header value 1")
.header("HEADER_2", "header value 2")
.attribute("requestId", UUID.randomUUID().toString())
.attribute("aUrl", theUrl) // private URL theUrl;
// .attributes(m())
.exchange();
I get a Bad Request (400) as response. Trying to use .attributes
instead of .attribute
results in a 400 either.
The REST controller's endpoint:
@PostMapping(value = "/endpoint", produces = {MediaType.APPLICATION_JSON_VALUE})
@ResponseStatus(HttpStatus.ACCEPTED)
public ResponseEntity<?> triggerAction(@RequestAttribute final HttpHeaders httpHeaders, @RequestAttribute final String requestId, @NonNull @RequestAttribute(value = "myActionUrl") final URL myActionUrl) {
...
}
Console output:
2021-11-19 09:06:08.050 ERROR [main] [] [] [VNB_REST_OUTBOUND_ADAPTER] [system] [Initiale Log Konfiguration] o.s.t.w.r.server.ExchangeResult:231 - Request details for assertion failure:

You can see that the attributes I tried to add seems not to be considered.
CodePudding user response:
Assuming you are talking about request parameters the simplest way is using WebClient.Builder
as follows:
var uriTemplate = "http://localhost:10080/endpoint?requestId={requestId}&aUrl={aUrl}";
var respSpec = webClientBuilder.baseUr(uriTemplate).build()
.post()
.uri( uri -> uri.build(UUID.randomUUID(), theUrl) )
.header(apiSecretHeader, secret)
.header("HEADER_1", "header value 1")
.header("HEADER_2", "header value 2")
.exchange();
If you prefer to not use the URI template, you would need to specify everything in the URI as follows:
var respSpec = webTestClient.post()
.uri( uriBuilder - > uriBuilder
.scheme("http")
.host("localhost")
.port("10080")
.path("/endpoint")
.queryParam("requestId", requestId)
.queryParam("aUrl", aUrl)
.build())
.header(apiSecretHeader, secret)
.header("HEADER_1", "header value 1")
.header("HEADER_2", "header value 2")
.exchange();
