Ausnahme mit der Nachricht "HTTP -Protokoll wird nicht unterstützt" bei Verwendung von RestTemplate ⇐ Java

[Anonymous]

Ich versuche, eine URL mit einer GET -Anforderung mit RastTemplate zu treffen. Es gibt eine Ausnahme, in der das HTTP -Protokoll nicht unterstützt wird. Aber ich kann dies nicht mit der REST -Vorlage tun. Ich werde die tatsächliche IP und den Port mit IP verwendet: Port. < /P>

Code: Select all

final String url = "http://ip:port/h2h.php?channelid=acrs&posid=1";
final HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.setContentType(MediaType.APPLICATION_XML);
httpHeaders.set(HttpHeaders.ACCEPT, MediaType.APPLICATION_XML_VALUE);
final HttpEntity httpEntity = new HttpEntity("", httpHeaders)
restTemplate.exchange(url, HttpMethod.GET, httpEntity, String.class);
< /code>
