JAX RS客戶端API攔截

Question

有沒有辦法來添加頁眉到通過攔截請求，但沒有通過顯式設置一個頭，當使用JAX RS客戶端API：

Client client = ClientBuilder.newClient(); 
Response response = client.target("someUrl").path("somePath").request().get(); 

在AOP方式

Answer 1

創建ClientRequestFilter：

@Provider 
public class MyClientRequestFilter implements ClientRequestFilter { 

    @Override 
    public void filter(ClientRequestContext requestContext) throws IOException { 
     requestContext.getHeaders().add("Authorization", "value"); 
    } 
} 

而且在註冊它的Client：

Client client = ClientBuilder.newClient().register(MyClientRequestFilter.class);
