将授权标头添加到Jersey SSE Client请求

Question

我正在使用Jersey客户端连接到SSE流.服务器要求我向http请求添加标头以进行授权,但我无法弄清楚如何添加标头.

这是我的代码:

Client client = ClientBuilder.newBuilder().register(SseFeature.class).build();
WebTarget target = client.target(baseurl + "/v1/devices/events/");
eventSource = EventSource.target(target).build();
eventSource.register(getEventListener());
eventSource.open();

以下是我需要添加的标头示例:

Authorization: Bearer 38bb7b318cc6898c80317decb34525844bc9db55

Answer 1

对于基本身份验证,它会是这样的:

Client client = ClientBuilder.newClient();
HttpAuthenticationFeature feature = HttpAuthenticationFeature.basicBuilder().build();
client.register(feature);
client.register(SseFeature.class);
WebTarget target = client.target(baseurl + "/v1/devices/events/")
    .property(HttpAuthenticationFeature.HTTP_AUTHENTICATION_BASIC_USERNAME, "...")
    .property(HttpAuthenticationFeature.HTTP_AUTHENTICATION_BASIC_PASSWORD, "...");

...

您已经获得了Jersey编码的密码.

如果它是一个令牌:

Client client = ClientBuilder.newClient();
WebTarget target = client.target(baseurl + "/v1/devices/events/")
    .request("...")     
    .header(HttpHeaders.AUTHORIZATION, "Bearer " + "... encoded token ...");

希望能帮助到你!

如果有人想在Client实体级别本身而不是在Request实体级别添加不记名令牌标头（在我的情况下，我有一个返回预配置Client实体的工厂方法，因此我无法在工厂中添加授权标头方法，.header(...)只有在您通过ClientBuilder.newBuilder().register(...).build().target(...).request(...)调用链后才可用，从 Jersey 2.x 开始）：

// client is a javax.ws.rs.client.Client entity
Feature feature = OAuth2ClientSupport.feature("YOUR_BEARER_TOKEN");
client.register(feature);
// now you can use client.target(...).request(...).post(...), without calling .header(...) after .request(...)

不幸的是（你可能已经猜到了）这需要一个新的依赖： org.glassfish.jersey.security:oauth2-client

<dependency>
  <groupId>org.glassfish.jersey.security</groupId>
  <artifactId>oauth2-client</artifactId>
  <version>2.15</version>
</dependency>

这是完整的示例

ClientConfig clientConfig = new ClientConfig();
Client client = ClientBuilder.newClient(clientConfig);
WebTarget webTarget = client.target("http://localhost:8080/MyApp/customer/");
Invocation.Builder invocationBuilder = 
webTarget.request(MediaType.APPLICATION_JSON).header(HttpHeaders.AUTHORIZATION, "your 
secret key");
response = invocationBuilder.get();
output = response.readEntity(String.class);

  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-client</artifactId>
