Java uses httpclient for POST request (HTTPS) Instances _java

Recently, we need to do a wrapper on the customer's interface, and then for their own company system calls, the customer interface is implemented with the HTTP URL, I would like to use the HttpClient package to request, and because the requested URL is HTTPS, in order to avoid the need for a certificate, So you inherit the Defaulthttpclient class with a class, ignoring the checksum process.

1. Write a sslclient class, inherit to HttpClient

Package Com.pcmall.service.sale.miaomore.impl;  
Import java.security.cert.CertificateException;  
Import Java.security.cert.X509Certificate;  
Import Javax.net.ssl.SSLContext;  
Import Javax.net.ssl.TrustManager;  
Import Javax.net.ssl.X509TrustManager;  
Import Org.apache.http.conn.ClientConnectionManager;  
Import Org.apache.http.conn.scheme.Scheme;  
Import Org.apache.http.conn.scheme.SchemeRegistry;  
Import Org.apache.http.conn.ssl.SSLSocketFactory;  
Import org.apache.http.impl.client.DefaultHttpClient;  
    The httpclient public class Sslclient extends for HTTPS requests defaulthttpclient{public sslclient () throws exception{  
    Super ();  
    Sslcontext CTX = sslcontext.getinstance ("TLS"); X509trustmanager TM = new X509trustmanager () {@Override public void checkclienttrusted (X509certificat E[] chain, String authtype) throws certificateexception {} @Override public V OID checkservertrusted (x509certificate[] ChAin, String authtype) throws certificateexception {} @Override public x509cer  
        Tificate[] Getacceptedissuers () {return null;  
    }  
    };  
    Ctx.init (NULL, new TRUSTMANAGER[]{TM}, NULL);  
    Sslsocketfactory SSF = new Sslsocketfactory (ctx,sslsocketfactory.allow_all_hostname_verifier);  
    Clientconnectionmanager CCM = This.getconnectionmanager ();  
    schemeregistry sr = Ccm.getschemeregistry ();  
  Sr.register (New Scheme ("https", 443, SSF));   }  
}

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

Package Com.pcmall.service.sale.miaomore.impl;  
Import java.util.ArrayList;  
Import Java.util.Iterator;  
Import java.util.List;  
Import Java.util.Map;  
Import Java.util.Map.Entry;  
Import org.apache.http.HttpEntity;  
Import Org.apache.http.HttpResponse;  
Import Org.apache.http.NameValuePair;  
Import org.apache.http.client.HttpClient;  
Import org.apache.http.client.entity.UrlEncodedFormEntity;  
Import Org.apache.http.client.methods.HttpPost;  
Import Org.apache.http.message.BasicNameValuePair;  
Import Org.apache.http.util.EntityUtils; * * Tool class with httpclient for post requests/public class Httpclientutil {public string doPost (string url,map<string,str  
    Ing> map,string CharSet) {httpclient httpclient = null;  
    HttpPost httppost = null;  
    String result = null;  
      try{httpclient = new Sslclient ();  
      HttpPost = new HttpPost (URL);  
      Set parameter list<namevaluepair> List = new arraylist<namevaluepair> (); Iterator iterator = Map.entryset (). iterator ();  
        while (Iterator.hasnext ()) {entry<string,string> Elem = (entry<string, string>) Iterator.next ();  
      List.add (New Basicnamevaluepair (Elem.getkey (), Elem.getvalue ()));  
        } if (List.size () > 0) {urlencodedformentity entity = new urlencodedformentity (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 ();  
  return result;   }  
}

3. To invoke the test code for the POST request

Package Com.pcmall.service.sale.miaomore.impl;  
Import Java.util.HashMap;  
Import Java.util.Map;  
  Testing the interface public class Testmain {private String URL = "https://xxx.xxx.xxx/";  
  Private String charset = "Utf-8";  
    
  Private Httpclientutil httpclientutil = null;  
  Public Testmain () {httpclientutil = new httpclientutil ();  
    public void Test () {String httporgcreatetest = url + ' xxx/xxx/delivery ';  
    map<string,string> Createmap = new hashmap<string,string> ();  
    Createmap.put ("Delivery_code", "1d1qz222z22sm21a");  
    Createmap.put ("timestamp", "1479198840000");  
    Createmap.put ("sign", "F2109c333f3eade929f932e89703fa0f683d43eb");  
    String Httporgcreatetestrtn = Httpclientutil.dopost (Httporgcreatetest,createmap,charset);  
  SYSTEM.OUT.PRINTLN ("Result:" +httporgcreatetestrtn);  
    public static void Main (string[] args) {Testmain main = new Testmain ();  
  Main.test ();   }  
}

The beginning is not very understand the use of basicnamevaluepair, and then slowly groped for a moment, found that Basicnamevaluepair is a class to store key-value pairs, when adding new key and value values, it will automatically replace the format of HTTP, = and & Symbol , such as https://xxx.xxx.xxx/xxx/xxxx/delivery?delivery_code=DQZZSM2A&timestamp=1479198840000&sign= F209c33feade99f93e8970fa0f68d3eb, we do not have their own stitching and matching, personally think it is very convenient to use and high accuracy, hope to help everyone!

The above is a small series for everyone to bring Java using httpclient for POST request (HTTPS) instance of all the content, I hope that we support cloud-Habitat Community ~
