URL中的Spring RestTemplate基本身份验证

Question

我知道关于这个主题的讨论已经存在，但我无法找到解决我的情况的答案：我想直接通过URL传递凭据（遵循https://user:pass@URL方案）。我得到一个401错误代码：

final RestTemplate restTemplate = new RestTemplate();
final ResponseEntity<String> wsCalendarResponse = restTemplate.getForEntity("https://user:[e-mail]", String.class);

有没有比这个答案更简单的线索：使用spring restTemplate对REST API进行基本身份验证？

谢谢

看来Spring RestTemplate在URL中没有基本的身份验证。所以我在URL调用之前添加了一些代码，以便考虑到URL中是否存在凭据：

final String urlWs = "https://user:[e-mail]";
final HttpHeaders headers = new HttpHeaders();
final String pattern = "^(?<protocol>.+?//)(?<username>.+?):(?<password>.+?)@(?<address>.+)$";
final Pattern regExpPattern = Pattern.compile(pattern);
final Matcher matcher = regExpPattern.matcher(urlWs);
if(matcher.find()) {
   final String username = matcher.group("username");
   final String password = matcher.group("password");
   final String plainCreds = username + ":" + password;
   final byte[] plainCredsBytes = plainCreds.getBytes();
   final byte[] base64CredsBytes = Base64Utils.encode(plainCredsBytes);
   final String base64Creds = new String(base64CredsBytes);
   headers.add("Authorization", "Basic " + base64Creds);
}
final HttpEntity<String> request = new HttpEntity<String>(headers);
final RestTemplate restTemplate = new RestTemplate();
final ResponseEntity<String> wsCalendarResponse = restTemplate.exchange(urlWs, HttpMethod.GET, request, String.class);

这是工作良好，即使没有凭据。
