On running a code I am getting the error: unable to find valid certification path to requested target
I am making a simple HTTP POST call to reqres.in/api/users. What could be the reason for this?
Code:
@Test
public void simplePostReqTest() throws URISyntaxException {
WebClient client = WebClient.create();
MultiValueMap<String, String> bodyValues = new LinkedMultiValueMap<>();
bodyValues.add("name", "olu");
bodyValues.add("job", "apple");
String response = client.post()
.uri(new URI("https://reqres.in/api/users"))
.contentType(MediaType.APPLICATION_JSON)
.body(BodyInserters.fromFormData(bodyValues))
.retrieve()
.bodyToMono(String.class)
.block();
System.out.println(response);
}
