java - Jetty:如何在 Jetty 客户端使用 SSL

Question

我正在使用 Jetty 开发我的客户端应用程序。我没有在服务器部分使用 Jetty。我需要在客户端配置什么才能使用 Jetty 客户端发送“https”请求？

这就是我为 HTTP 客户端所做的:

httpClient = new HttpClient();
// Configure HttpClient
httpClient.setFollowRedirects(false);

httpClient.start();

Request request = httpClient.newRequest(url);
//code
httpClient.stop();

如果我尝试使用“https”发送请求，则会出现此异常:

java.util.concurrent.ExecutionException: java.lang.NullPointerException

自 jetty-client >= 10

HttpClient supports HTTPS requests out-of-the-box like a browser does.

之前的 jetty-client 9

In order to perform HTTPS requests, you should create first a SslContextFactory.Client

您必须像这样将 SslContextFactory 传递到 HttpClient 中:

HttpClient httpClient = new HttpClient(new SslContextFactory());

您甚至可以通过信任所有或给它一个 keystore 来配置 SslContextFactory:

new SslContextFactory(true);
new SslContextFactory("/path/to/.keystore");
