How to request HTTPS using Java

TLS version for JDK (for reference only)

1. Write a sslclient class, inherit to HttpClient

Importjava.security.cert.CertificateException; Importjava.security.cert.X509Certificate; ImportJavax.net.ssl.SSLContext; ImportJavax.net.ssl.TrustManager; ImportJavax.net.ssl.X509TrustManager; ImportOrg.apache.http.conn.ClientConnectionManager; ImportOrg.apache.http.conn.scheme.Scheme; ImportOrg.apache.http.conn.scheme.SchemeRegistry; Importorg.apache.http.conn.ssl.SSLSocketFactory; Importorg.apache.http.impl.client.DefaultHttpClient; //HttpClient for HTTPS requests Public classSslclientextendsdefaulthttpclient{ PublicSslclient ()throwsexception{Super();
　　　　　//transport protocol needs to be judged by its own Sslcontext CTX= Sslcontext.getinstance ("TLSv1.2"); X509trustmanager TM=NewX509trustmanager () {@Override Public voidcheckclienttrusted (x509certificate[] chain, String authtype)throwscertificateexception {} @Override Public voidcheckservertrusted (x509certificate[] chain, String authtype)throwscertificateexception {} @Override Publicx509certificate[] Getacceptedissuers () {return NULL;          }          }; Ctx.init (NULL,NewTRUSTMANAGER[]{TM},NULL); Sslsocketfactory SSF=Newsslsocketfactory (Ctx,sslsocketfactory.allow_all_hostname_verifier); Clientconnectionmanager CCM= This. Getconnectionmanager (); Schemeregistry SR=Ccm.getschemeregistry (); Sr.register (NewScheme ("https", 443, SSF)); }  }  

2. Write a class that uses httpclient to send a POST request

Importjava.util.ArrayList; ImportJava.util.Iterator; Importjava.util.List; ImportJava.util.Map; ImportJava.util.Map.Entry; Importorg.apache.http.HttpEntity; ImportOrg.apache.http.HttpResponse; ImportOrg.apache.http.NameValuePair; Importorg.apache.http.client.HttpClient; Importorg.apache.http.client.entity.UrlEncodedFormEntity; ImportOrg.apache.http.client.methods.HttpPost; ImportOrg.apache.http.message.BasicNameValuePair; Importorg.apache.http.util.EntityUtils; /** Tool class for Post requests with HttpClient*/   Public classHttpclientutil { PublicString DoPost (String url,map<string,string>map,string CharSet) {HttpClient HttpClient=NULL; HttpPost HttpPost=NULL; String result=NULL; Try{httpClient=Newsslclient (); HttpPost=Newhttppost (URL); //Setting Parameterslist<namevaluepair> list =NewArraylist<namevaluepair>(); Iterator Iterator=Map.entryset (). iterator ();  while(Iterator.hasnext ()) {Entry<String,String> Elem = (entry<string, string>) Iterator.next (); List.add (NewBasicnamevaluepair (Elem.getkey (), Elem.getvalue ())); }              if(List.size () > 0) {urlencodedformentity entity=Newurlencodedformentity (List,charset);              Httppost.setentity (entity); } HttpResponse Response=Httpclient.execute (HttpPost); if(Response! =NULL) {httpentity resentity=response.getentity (); if(Resentity! =NULL) {result=entityutils.tostring (Resentity,charset); }              }          }Catch(Exception ex) {ex.printstacktrace (); }          returnresult; }  }  

3. Calling the requested test code

ImportJava.util.HashMap; ImportJava.util.Map; //Testing the interface Public classTestmain {PrivateString url = "https://192.168.1.101/"; PrivateString charset = "Utf-8"; PrivateHttpclientutil Httpclientutil =NULL;  PublicTestmain () {Httpclientutil=NewHttpclientutil (); }             Public voidTest () {String httporgcreatetest= URL + "Httporg/create"; Map<String,String> Createmap =NewHashmap<string,string>(); Createmap.put ("Authuser", "* * * * *"); Createmap.put ("Authpass", "* * * * *"); Createmap.put ("Orgkey", "* * *"); Createmap.put ("OrgName", "* * *"); String Httporgcreatetestrtn=Httpclientutil.dopost (Httporgcreatetest,createmap,charset); System.out.println ("Result:" +Httporgcreatetestrtn); }             Public Static voidMain (string[] args) {Testmain main=NewTestmain ();      Main.test (); }  }
