Jetty: How to use SSL in Jetty client side

Ask Time：2015-10-15T18:47:50 Author：sabrina2020

I am using Jetty to develop my client application side. I am not using Jetty in the server part. What I need to configure on the client side to be able send "https" request using the Jetty client?

That is what I do for HTTP client:

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

httpClient.start();

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

I got this exception if I try to send request using "https":

Roald Bankras :

Since jetty-client >= 10\nHttpClient supports HTTPS requests out-of-the-box like a browser does.\n\nPrior jetty-client 9\nIn order to perform HTTPS requests, you should create first a SslContextFactory.Client\nYou have to pass a SslContextFactory into the HttpClient like this:\nHttpClient httpClient = new HttpClient(new SslContextFactory());\n\nYou can even configure the SslContextFactory by trusting all or give it a keystore:\nnew SslContextFactory(true);\nnew SslContextFactory("/path/to/.keystore");\n",
