java - HttpClientErrorException : 401 Unauthorized basic authentication

Question

我正在尝试通过基本身份验证获取网址。我设置用户/密码如下。同样的凭证也在 postman 中工作。

String RELATIVE_IDENTITY_URL  = "http://my_url/api/core/v3/people/email/abc@example.com";
    RestTemplate restTemplate;
    Credentials credentials;

    //1. Set credentials
    credentials = new UsernamePasswordCredentials("admin", "admin");

    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials( AuthScope.ANY, credentials);

    //2. Bind credentialsProvider to httpClient
    HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
    httpClientBuilder.setDefaultCredentialsProvider(credsProvider);
    CloseableHttpClient httpClient = httpClientBuilder.build();

    HttpComponentsClientHttpRequestFactory factory = new  
            HttpComponentsClientHttpRequestFactory(httpClient);

    //3. create restTemplate
    restTemplate = new RestTemplate();
    restTemplate.setRequestFactory(factory);

    //4. restTemplate execute
    String url = RELATIVE_IDENTITY_URL;

    String xml = restTemplate.getForObject(url,String.class); 
    System.out.println("Done");

我认为凭据设置不正确。这里有什么问题吗？错误:

Answer 1

您缺少 auth header 并在其余模板执行中设置凭据。
