HttpClient supporting multiple TLS protocols

阅读更多关于 HttpClient supporting multiple TLS protocols

问题 We're writing an app that must communicate with a few servers using HTTPS. It needs to communicate with AWS (using the AWS libraries) and also with some of our internal services that use TLS 1.2. I started off by changing my HttpClient to use a TLS 1.2 SSLContext: public static SchemeRegistry buildSchemeRegistry() throws Exception { final SSLContext sslContext = SSLContext.getInstance("TLSv1.2"); sslContext.init(createKeyManager(), createTrustManager(), new SecureRandom()); final

Migrating from HttpClient 3.x to 4.x

阅读更多关于 Migrating from HttpClient 3.x to 4.x

We have some code written using commons-httpclient-3.1 that needs to be converted to 4.1. I'm only somewhat familiar with this and am reading the 4.1 httpclient tutorial now. I see a couple of posts here (e.g. Converting from HttpClient 3 to 4 but that's about a specific construct). Seems like there should be some docs/examples somewhere showing how to upgrade usage of 3.x to 4.x ? One specific example: replacing use of org.apache.commons.httpclient.HttpState I would replace the library jar(s) in your IDE and look for compiler errors to start with. You may wish to go back and check all usages

阅读更多关于 Confused with different methods of creating cookie in HttpClient

问题 There are different methods to create cookies in HttpClient, I am confused which one is the best. I need to create,retrieve and modify cookies.

Thank a lot in advanced for any help and ideas. public class ClientKerberosAuthentication { public static void main(String[] args) throws Exception { System.setProperty("java.security.auth.login.config", "login.conf"); System.setProperty(

问题 I want to use mutual SSL authentication between service A and B. I'm currently implementing passing the client certificate from service A in Java.

DefaultHttpClient client = new DefaultHttpClient(); byte [] certificate = localCertManager.retrieveCert(); I have very little experience in this area and I
