问题 Performing millions of HTTP requests with different Java libraries gives me threads hanged on: java.net.SocketInputStream.socketRead0() Which is native function. I tried to set up Apche Http Client and RequestConfig to have timeouts on (I hope) everythig that is possible but still, I have (probably infinite) hangs on socketRead0 . How to get rid of them?

问题 I'm trying to send a GET request using HttpClient , but I keep getting an IllegalStateException . Any idea what's causing this? I've been looking around for a solution, but I don't get what it means by "host=null" in the log. How do I set the host, and how is it different from the path?

问题 Does the library Apache Commons HttpClient support Gzip? We wanted to use enable gzip compression on our Apache server to speed up the client/server communications (we have a php page that allows our Android application to sync files with the Server). 回答1: Apache HttpClient 4.1 supports content compression out of the box along with many other features that were previously considered out of scope. 回答2: If your server is able to provide GZIPped content, with Apache Http client 4.1 all you need

问题 Is there a way to specify a timeout for the whole execution of HttpClient? I have tried the following: httpClient.getParams().setParameter("http.socket.timeout", timeout * 1000); httpClient.getParams().setParameter("http.connection.timeout", timeout * 1000); httpClient.getParams().setParameter("http.connection-manager.timeout", new Long(timeout * 1000)); httpClient.getParams().setParameter("http.protocol.head-body-timeout", timeout * 1000); It actually works fine, except if a remote host

问题 How can I change the supported TLS versions on my HttpClient? I'm doing: SSLContext sslContext = SSLContext.getInstance("TLSv1.1"); sslContext.init( keymanagers.toArray(new KeyManager[keymanagers.size()]), null, null); SSLSocketFactory socketFactory = new SSLSocketFactory(sslContext, new String[]{"TLSv1.1"}, null, null); Scheme scheme = new Scheme("https", 443, socketFactory); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register(scheme); BasicClientConnectionManager

问题 can you tell me how to store jsessionid in cookie, so it can be passed to the servlet with post request? I'm using Apache HttpClient version 4.0.3. All the solutions I've found explains how to do this with HttpClient 3.1. I've read tutorial and tried this, but it isn't working. HttpPost httppost = new HttpPost(postData); CookieStore cookieStore = new BasicCookieStore(); BasicClientCookie cookie = new BasicClientCookie("JSESSIONID", getSessionId()); cookieStore.addCookie(cookie); client

问题 All I'm trying to do is download some JSON and deserialize it into an object. I haven't got as far as downloading the JSON yet. Almost every single HttpClient example I can find, including those on the apache site looks something like... import org.apache.http.client.HttpClient; import org.apache.http.impl.client.DefaultHttpClient; public void blah() { HttpClient client = new DefaultHttpClient(); ... } However, Netbeans tells me that DefaultHttpClient is deprecated.
