Java calls the HTTPS interface, avoids the way the certificate

One, call with HttpClient

1. Add dependencies using Maven

<dependency>            <groupId>org.apache.httpcomponents</groupId>            <artifactId> httpclient</artifactid>            <version>4.5.  3</version>        </dependency>        <dependency>            <groupId> org.apache.httpcomponents</groupid>            <artifactId>httpmime</artifactId>            <version >4.5. 3</version>        </dependency>

2. Testing

Package Com.moy.whymoy.test;import Org.apache.http.httpentity;import Org.apache.http.client.methods.closeablehttpresponse;import Org.apache.http.client.methods.httpget;import Org.apache.http.client.methods.httppost;import Org.apache.http.conn.ssl.noophostnameverifier;import Org.apache.http.conn.ssl.sslconnectionsocketfactory;import Org.apache.http.conn.ssl.truststrategy;import Org.apache.http.entity.mime.multipartentitybuilder;import org.apache.http.impl.client.CloseableHttpClient; Import Org.apache.http.impl.client.httpclients;import Org.apache.http.ssl.sslcontexts;import Org.apache.http.util.entityutils;import Javax.net.ssl.*; import java.io.*; import Java.net.url;import java.security.keymanagementexception;import java.security.KeyStoreException; Import Java.security.nosuchalgorithmexception;import Java.security.cert.certificateexception;import Java.security.cert.X509Certificate;/** * [Project]:whymoy <br/> * [email]:[email protected] <br/> * [DATE]:2018/3/14 <br/> * [descript ION]: <br/> * * @author Yexiangyang*/ Public classMain { Public Static voidMain (string[] args) throws IOException, NoSuchAlgorithmException, Keystoreexception, keymanagementexception { String URL="https://kyfw.12306.cn/otn/"; Try(Closeablehttpclient httpClient =createhttpclient ()) {HttpGet HttpGet=Newhttpget (URL); Try(Closeablehttpresponse HttpResponse =Httpclient.execute (HttpGet)) {httpentity entity=httpresponse.getentity (); String result=entityutils.tostring (entity);                                Entityutils.consume (entity); System. out. printf (result); }        }    }    Private Staticcloseablehttpclient createhttpclient () throws Keystoreexception, NoSuchAlgorithmException, keymanagementexception {sslcontext Sslcontext=Sslcontexts.custom (). Loadtrustmaterial (NULL, (chain, AuthType)true). build (); Sslconnectionsocketfactory SSLSF=NewSslconnectionsocketfactory (Sslcontext,NULL,NULL,                Newnoophostnameverifier ()); returnHttpclients.custom (). Setsslsocketfactory (SSLSF). build (); }}

Second, using native httpsurlconnection call

Package Com.moy.whymoy.test;import Javax.net.ssl.httpsurlconnection;import javax.net.ssl.sslcontext;import Javax.net.ssl.trustmanager;import Javax.net.ssl.x509trustmanager;import Java.io.bufferedreader;import Java.io.ioexception;import Java.io.inputstreamreader;import Java.net.url;import Java.security.keymanagementexception;import Java.security.nosuchalgorithmexception;import Java.security.cert.certificateexception;import java.security.cert.X509Certificate;/** * [Project]:whymoy <br/> * [email]:[email protected] <br/> * [DATE]:2018/3/27 <br/> * [descript ION]: <br/> * * @author Yexiangyang*/ Public classRun { Public Static voidMain (string[] args) throws Keymanagementexception, NoSuchAlgorithmException, ioexception {String URL="https://kyfw.12306.cn/otn/"; Sslcontext SC=Createsslcontext (); Httpsurlconnection Conn= (httpsurlconnection)Newurl (url). OpenConnection ();        Conn.setsslsocketfactory (Sc.getsocketfactory ()); Conn.sethostnameverifier (S, sslsession)-true); Conn.setdoinput (true); Conn.setdooutput (true);        Conn.connect (); StringBuilder result=NewStringBuilder (); Try(BufferedReader br =NewBufferedReader (NewInputStreamReader (Conn.getinputstream ())))            {String line;  while(NULL! = (line =Br.readline ())) {Result.append (line). Append ("\ n");        }} conn.disconnect (); System. out. printf (result.tostring ()); }    Private StaticSslcontext Createsslcontext () throws NoSuchAlgorithmException, keymanagementexception {sslcontext sc= Sslcontext.getinstance ("SSL"); Sc.init (NULL,Newtrustmanager[]{NewX509trustmanager () {@Override Public voidcheckclienttrusted (x509certificate[] x509certificates, String s) throws certificateexception {} @Override Public voidcheckservertrusted (x509certificate[] x509certificates, String s) throws certificateexception {} @Override Publicx509certificate[] Getacceptedissuers () {return Newx509certificate[0]; }        }}, Newjava.security.SecureRandom ()); returnSC; }}
