使用RestTemplate进行基本身份validation（3.1）

我试图使用Java重现以下curl命令：

curl -v -u user:pass http://myapp.com/api 

此命令返回一些JSON数据。

我的错误Java实现如下：

 @Test public void callTest() { RestTemplate restTemplate = createRestTemplate("user", "pass"); URI uri = new URI("http://myapp.com/api"); String res = restTemplate.getForObject(uri, String.class); } private static RestTemplate createRestTemplate(String username, String password) { UsernamePasswordCredentials cred = new UsernamePasswordCredentials(username, password); BasicCredentialsProvider cp = new BasicCredentialsProvider(); cp.setCredentials(AuthScope.ANY, cred); DefaultHttpClient client = new DefaultHttpClient(); client.setCredentialsProvider(cp); ClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(client); RestTemplate restTemplate = new RestTemplate(factory); // set the media types properly return restTemplate; } 

然而，当我执行测试时，它返回一个org.springframework.web.client.HttpClientErrorException: 401 Unauthorized exception。

登录DEBUG ，我看不到有关身份validation的信息……

设置身份validation凭据时我做错了什么？

Answer 1

实例化使用

 HttpClient client = new HttpClient(); 

不再存在，并且从版本4.3的 HttpComponents HttpClient中弃用了类DefaultHttpClient 。 所以其他答案无效或已弃用。 这是我的版本，我为需要基本身份validation的rest请求编写了这个类：

 import org.apache.http.auth.AuthScope; import org.apache.http.auth.UsernamePasswordCredentials; import org.apache.http.client.CredentialsProvider; import org.apache.http.client.HttpClient; import org.apache.http.impl.client.BasicCredentialsProvider; import org.apache.http.impl.client.HttpClients; import org.springframework.http.client.HttpComponentsClientHttpRequestFactory; import org.springframework.web.client.RestTemplate; public class RestClient extends RestTemplate { public RestClient(String username, String password) { CredentialsProvider credsProvider = new BasicCredentialsProvider(); credsProvider.setCredentials( new AuthScope(null, -1), new UsernamePasswordCredentials(username, password)); HttpClient httpClient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build(); setRequestFactory(new HttpComponentsClientHttpRequestFactory(httpClient)); } } 

然后使用它，例如：

 RestClient restClient = new RestClient("username", "password"); String result = restClient.postForObject(... 

Answer 2

我做这样的事 – 它对我有用：

 private RestTemplate createRestTemplate(String username, String password) { return new RestTemplate(this.createSecureTransport(username, password)); } protected ClientHttpRequestFactory createSecureTransport(String username, String password){ HttpClient client = new HttpClient(); UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(username,password); client.getState().setCredentials(AuthScope.ANY, credentials); CommonsClientHttpRequestFactory commons = new CommonsClientHttpRequestFactory(client); return commons; } 

它在这里使用： 参考代码

Answer 3

这个答案基于@kevinpeterson的答案，但重写使用更新的Apache HTTP客户端。

 RestTemplate createRestTemplate(String username, String password, String host, int port ) { return new RestTemplate(this.createSecureTransport( username, password, host, port )); } ClientHttpRequestFactory createSecureTransport( String username, String password, String host, int port ){ DefaultHttpClient client = new DefaultHttpClient(); UsernamePasswordCredentials credentials = new UsernamePasswordCredentials( username, password ); client.getCredentialsProvider().setCredentials( new AuthScope( host, port ), credentials ); return new HttpComponentsClientHttpRequestFactory(client); 

Answer 4

httpclient v4.0不支持抢占式身份validation

看看这个： http ： //forum.springsource.org/showthread.php？123385-Preemptive-Basic-Authentication-with-RestTemplate

在springSource找到了这个解决方案。

这个对我有用。
