Jersey 客户端 API - 身份验证

Question

我正在使用 Jersey 客户端 API 向 JAX-WS Web 服务提交 SOAP 请求。默认情况下，Jersey 在受到质询时以某种方式使用我的 Windows Nt 凭据进行身份验证。谁能解释一下 Jersey 在代码中的位置？它可以被覆盖吗？

我尝试使用 HTTPBasicAuthFilter 并添加为客户端上的过滤器。我还尝试将我的凭据添加到 WebResoruce queryParams 字段，但是都没有被选中。

Answer 1

起初，我按照泽西岛用户指南中的记录进行了这项工作

Authenticator.setDefault (authinstance);

，但是我不喜欢这个，因为它依赖于设置全局身份验证器。经过一番研究，我发现 Jersey 有一个 HTTPBasicAuthFilter ，它更容易使用。

Client c = Client.create();
c.addFilter(new HTTPBasicAuthFilter(user, password));

看：
https://jersey .github.io/nonav/apidocs/1.10/jersey/com/sun/jersey/api/client/filter/HTTPBasicAuthFilter.html
https://jersey.github.io/nonav/apidocs/1.10/jersey/com/sun/jersey/api/client/filter/Filterable.html#addFilter(com.sun.jersey.api. client.filter.ClientFilter)

Answer 2

Jersey 2.x：

HttpAuthenticationFeature feature = HttpAuthenticationFeature.basicBuilder()
    .nonPreemptive()
    .credentials("user", "password")
    .build();

ClientConfig clientConfig = new ClientConfig();
clientConfig.register(feature) ;

Client client = ClientBuilder.newClient(clientConfig);

参考：5.9.1 。 HTTP认证支持

Answer 3

Jersey 用户指南中有一小节介绍客户端身份验证。我建议您遵循其建议并尝试使用 Apache HTTP Client 而不是 HttpURLConnection，因为它对您想做的任何事情都有更好的支持。

Answer 4

添加这个答案是因为我不断寻找旧版本 Jersey 的答案，这些版本在 2.x 中不再相关。

对于 Jersey 2 有多种方法。
看一下：

JavaDoc for org.glassfish.jersey.client.authentication.HttpAuthenticationFeature

这是为我工作的（最简单的基本身份验证恕我直言）。

    ClientConfig config = new ClientConfig();

    HttpAuthenticationFeature feature = HttpAuthenticationFeature.basic("username", "password");

    Client client = ClientBuilder.newClient(config);
    client.register(feature);

    WebTarget webTarget = client.target("http://api.asite.com/api").path("v1/reports/list");
    Invocation.Builder invocationBuilder =  webTarget.request(MediaType.TEXT_PLAIN_TYPE);

    Response response = invocationBuilder.get();

    System.out.println( response.getStatus() );
    System.out.println( response.readEntity(String.class) );

如果您正在测试 Dropwizard 应用程序（也许它适合任何 REST 服务），您可以使用以下示例：

请找到以下没有 SSL 的工作代码

，我正在使用 put request ，如果需要 post/get 只需更改它。

是的，对于 jersey 2.x，您可以执行此操作以使用基本身份验证（抢占模式）对每个请求进行身份验证：

 client.register(HttpAuthenticationFeature.basic(userName, password));
 // rest invocation code ..
