Apache HttpClient（4.1和更新版本）：如何进行基本身份验证？(Apache HttpClient (4.1 and newer): how to do basic authentication?)

 我们使用HttpClient进行基本身份验证，但我们不使用CredentialProvider 。 代码如下： 
 
HttpClient client = factory.getHttpClient(); //or any method to get a client instance
Credentials credentials = new UsernamePasswordCredentials(username, password);
client.getState().setCredentials(AuthScope.ANY, credentials);
 
 更新：在评论中指出， HttpClient.getState() 方法在API的3.x版本中可用。 但是， 较新版本的API不支持该方法。 

We do basic authentication with HttpClient, but we do not use CredentialProvider. Here's the code:
 
HttpClient client = factory.getHttpClient(); //or any method to get a client instance
Credentials credentials = new UsernamePasswordCredentials(username, password);
client.getState().setCredentials(AuthScope.ANY, credentials);
 
UPDATE: A stated in the comments, the HttpClient.getState() methos is available in version 3.x of the API. However, newer versions of the API doesn't support that method.
