How to execute a https GET request from java -

i wrote java client executes http requests without problem. want modify client in order

import org.apache.http.httphost; import org.apache.http.auth.authscope; import org.apache.http.auth.usernamepasswordcredentials; import org.apache.http.client.credentialsprovider; import org.apache.http.client.config.requestconfig; import org.apache.http.client.methods.closeablehttpresponse; import org.apache.http.client.methods.httpget; import org.apache.http.impl.client.basiccredentialsprovider; import org.apache.http.impl.client.closeablehttpclient; import org.apache.http.impl.client.httpclients; private string executeget(final string url, string proxy, int port) throws ioexception, requestunsuccesfulexception, invalidparameterexception { closeablehttpclient httpclient = null; string ret = ""; requestconfig config; seek { string hostname = extracthostname(url); logger.info("hostname {}", hostname); httphost target = new httphost(hostname, 80, null); httphost myproxy = new httphost(proxy, port, "http"); credentialsprovider credsprovider = new basiccredentialsprovider(); credsprovider.setcredentials( authscope.any, new usernamepasswordcredentials(username, password)); httpclient = httpclients.custom().setdefaultcredentialsprovider(credsprovider).build(); config = requestconfig.custom().setproxy(myproxy).build(); httpget request = new httpget(url); request.setconfig(config); closeablehttpresponse response = httpclient.execute(target, request); ...

now have send https requests instead of https. expecting easy modification httpsget instead of httpget not, there no httpsget class available.

what easiest way modify method in order handle https requests.

this quick , dirty https client in java, ignores invalid certificates , authenticates using basic

import java.io.ioexception; import java.net.url; import java.security.keymanagementexception; import java.security.nosuchalgorithmexception; import javax.net.ssl.httpsurlconnection; import javax.net.ssl.sslcontext; import javax.net.ssl.trustmanager; public static httpsurlconnection getconnection(boolean ignoreinvalidcertificate, string user, string pass, httprequestmethod httprequestmethod, url url) throws keymanagementexception, nosuchalgorithmexception, ioexception{ sslcontext ctx = sslcontext.getinstance("tls"); if (ignoreinvalidcertificate){ ctx.init(null, new trustmanager[] { new invalidcertificatetrustmanager() }, null); } sslcontext.setdefault(ctx); string authstr = user+":"+pass; string authencoded = base64.encodebytes(authstr.getbytes()); httpsurlconnection connection = (httpsurlconnection) url.openconnection(); connection.setrequestmethod("get"); connection.setdooutput(true); connection.setrequestproperty("authorization", "basic " + authencoded); if (ignoreinvalidcertificate){ connection.sethostnameverifier(new invalidcertificatehostverifier()); } homecoming connection; }

--

import javax.net.ssl.hostnameverifier; import javax.net.ssl.sslsession; public class invalidcertificatehostverifier implements hostnameverifier{ @override public boolean verify(string paramstring, sslsession paramsslsession) { homecoming true; } }

import java.security.cert.certificateexception; import java.security.cert.x509certificate; import javax.net.ssl.x509trustmanager; /** * ignore invalid https certificate opam * <p>see http://javaskeleton.blogspot.com.br/2011/01/avoiding-sunsecurityvalidatorvalidatore.html */ public class invalidcertificatetrustmanager implements x509trustmanager{ @override public x509certificate[] getacceptedissuers() { homecoming null; } @override public void checkservertrusted(x509certificate[] paramarrayofx509certificate, string paramstring) throws certificateexception { } @override public void checkclienttrusted(x509certificate[] paramarrayofx509certificate, string paramstring) throws certificateexception { } }

maybe it's can start with.

of course, since have connection, can retrieve response contents using

inputstream content = (inputstream) connection.getinputstream();

java https get
