Как преобразовать запрос curl с базовой аутентификацией HTTP в запрос Spring RestTemplate?

Question

Как преобразовать следующий curl запрос на использование Spring RestTemplate?

curl -u 751061:123456 -i -k -X PUT https://server/api/User/751061 -H 'Content-type: application/xml' -d '<User><state>LOGIN</state><extension>751055</extension></User>'

Я пытался следовать руководству, но в нем ничего не говорится об аутентификации (и XML).

https://spring.io/guides/gs/consuming-rest/#_make_the_application_executable

Документ API ничего не упоминает об аутентификации.

https://docs.spring.io/spring/docs/5.0.8.BUILD-SNAPSHOT/javadoc-api/org/springframework/web/client/RestTemplate.html

Я попробовал следующее

@PostMapping("/login")
public String login(@RequestParam(name="userId", required=true) String userId,
        @RequestParam(name="password", required=true) String password,
        @RequestParam(name="extension", required=true) String extension,
        HttpSession session,
        RestTemplateBuilder builder) {
    User user = new User();
    user.state = "LOGIN";
    user.extension = extension;
//      RestTemplate restTemplate = new RestTemplate();
//      restTemplate.set
    RestTemplate restTemplate = builder.basicAuthorization(userId, password).build();
    restTemplate.put("https://server/api/User/"+userId, user);

Но получил исключение

Я попробовал следующее

public String login(@RequestParam(name="userId", required=true) String userId,
        @RequestParam(name="password", required=true) String password,
        @RequestParam(name="extension", required=true) String extension,
        HttpSession session
        /*RestTemplateBuilder builder*/) throws KeyManagementException, NoSuchAlgorithmException {
    User user = new User();
    user.state = "LOGIN";
    user.extension = extension;

    // turn off SSL checking // https://stackoverflow.com/a/24491820/148844
    X509TrustManager[] tm = new X509TrustManager[] {new TrustAllX509TrustManager()}; // from IdS client SDK
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init( null, tm, null );
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

    // set authentication headers
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_XML);
    String plainClientCredentials = userId + ":" + password;
    String base64ClientCredentials = new String(Base64.encodeBase64(plainClientCredentials.getBytes()));
    headers.add("Authorization", "Basic " + base64ClientCredentials);
    HttpEntity request = new HttpEntity(null, headers);
    // make request
    RestTemplate restTemplate = new RestTemplate();
    String url = "https://server/api/User/"+userId;
    restTemplate.put(url, request, user);

но получил ошибку

org.springframework.web.client.HttpClientErrorException: 400 Bad Request

Работает с curl.

Я добавил

restTemplate.setErrorHandler(new ResponseErrorHandler() {

    @Override
    public void handleError(ClientHttpResponse arg0) throws IOException {
        byte[] b = new byte[arg0.getBody().available()];
        arg0.getBody().read(b);
        System.out.println(new String(b));
    }

    @Override
    public boolean hasError(ClientHttpResponse arg0) throws IOException {
        return arg0.getRawStatusCode() != 202;
    }

});
System.out.println("\n\n\n********************************************************************");
restTemplate.put(url, request, user);

и получил

********************************************************************
<ApiErrors>
  <ApiError>
    <ErrorType>Invalid Input</ErrorType>
    <ErrorData>User</ErrorData>
    <ErrorMessage> : Premature end of file.</ErrorMessage>
  </ApiError>
</ApiErrors>

Вы пробовали это?

restTemplate.getInterceptors().add(new BasicAuthorizationInterceptor("username", "password"));
