Android series five (send parameters via get or post to web App)

Not much nonsense to say, directly on the code comparison is real.

In fact, it is also a record of their own way, for the future of lazy preparation .... Don't hit me, I'm a lazy man ~

Send parameters based on the Get method of the HTTP protocol:

/** *  send GET request  *  @param   path  request path  *  @param   params   Request Parameters  *  @param   encoding  encoding  *  @return    request succeeded  */private  static boolean sendgetrequest (String path,map<string, string> params,  string coding)  throws Exception{                 //Stitching url    stringbuilder url =  New stringbuilder (path);     url.append ("?");     for (Map.entry<string, string> entry : params.entryset ()) {         url.append (Entry.getkey ()). Append ("=");         url.append (Urlencoder.encode (Entry.getvalue (),  coding));         url.append ("&");    }    url.deletecharat (Url.length ()  - 1);              //Creating a connection     httpurlconnection conn =   (httpurlconnection) New url (url.tostring ()). OpenConnection ();     Conn.setconnecttimeout,     conn.setrequestmethod ("GET");     if ( Conn.getresponsecode ()  == 200) {        return true;     }    return false;}

Post method based on HTTP protocol send parameters:

/** *  send POST request  *  @param   path  request path  *  @param  params  request Parameters  *  @param  encoding  encoding  *  @return   Request Success  */private static  Boolean sendpostrequest (string path, map<string, string> params, string  encoding)  throws exception{    //encapsulated into time=60&name=ceshishipin  Such data     stringbuilder data = new stringbuilder ();     if (Params!=null && !params.isempty ()) {    for (Map.Entry<String,  string> entry : params.entryset ()) {         Data.append (Entry.getkey ()). Append ("=");         data.append ( Urlencoder.encode (Entry.getvalue (),  encoding));         Data.append ("&");     &Nbsp; }        data.deletecharat (Data.length ()  - 1);     }    byte[] entity = data.tostring (). GetBytes ();// Generate Entity Data     HttpURLConnection conn =  (httpurlconnection)  new url ( Path). OpenConnection ();     conn.setconnecttimeout (;    ) Conn.setrequestmethod ("POST");     conn.setdooutput (true);//Allow external output data      //set the properties of the request    content-type  content-length these two are necessary    etc to cooike  Or the session should also set the corresponding property     conn.setrequestproperty ("Content-type",  "application/ X-www-form-urlencoded ");     conn.setrequestproperty (" Content-length ",  String.valueOf ( entity.length));     outputstream outstream = conn.getoutputstream ();     outstream.write (entity); &NBsp;   if (Conn.getresponsecode ()  == 200) {         return true;    }    return false;}

method of sending data: (Here I only send two parameters)

/** *  sending data  *  @param  name   parameters one  *  @param  time     Parameters two  *  @return      success  *  @throws  exception */public  static boolean send (string name, string time)  throws exception{//  TODO Auto-generated method stub    String url =  " The path you requested ";    map<string, string> params = new hashmap< String, string> ();     params.put ("name",  name);     Params.put ("Time",  time);    try {         return sendhttpclientpostrequest (url, params,  "UTF-8");    }  catch  (exception e)  {        e.printstacktrace ();     }    rEturn false;} 

Usage in activity or using threads to update the UI

Public void send (VIEW V) {    final string name =  Edit1.gettext (). toString ();     final string time = edit2.gettext (). ToString ();     final handler handler = new handler () {     public void handlemessage (message msg) {         switch  (msg.what)  {             case 0:                 Toast.maketext (Getapplicationcontext (),  r.string.success, 1)              .show ();             break;            case 1:        &nBsp;        toast.maketext (Getapplicationcontext (),  r.string.error, 1)             .show ();             break;             default:             break;            }         }    };    new thread (New Runnable ()  {     @Override     public void run ()  {       try {               boolean result = videoservice.send (name,time);            &nBsp;if (Result) {                 handler.sendemptymessage (0);             }  else {                 handler.sendemptymessage (1);             }     } catch  (exception e)  {         e.printstacktrace ();        }    }     }). Start ();}

Here I do not use the button listener event directly in the Main.xml configuration: android:onclick= "send"//Use the Send method above

Look online says there is a ready-made framework (httpClient) that can be used:

  /** *  send post requests via httpclient  *  @param  path  request Path  *  @param  params  Request Parameters  *  @param  encoding  encoding  *  @return   Request succeeded  */private  static boolean sendhttpclientpostrequest (string path, map<string, string>  params, string encoding)  throws Exception{    List< Namevaluepair> pairs = new arraylist<namevaluepair> ();//Store Request Parameters      if (Params!=null && !params.isempty ()) {    for (Map.Entry<String,  string> entry : params.entryset ()) {         Pairs.add (New basicnamevaluepair (Entry.getkey (),  entry.getvalue ()));         }    }    urlencodedformentity entity =  new urlencodedformentiTy (pairs, encoding);  //Generating Entity Data     HttpPost httpPost = new  HttpPost (path);     httppost.setentity (entity);     defaulthttpclient  client = new defaulthttpclient ();   //simulates a browser behavior      Httpresponse response = client.execute (HttpPost);     if ( Response.getstatusline (). Getstatuscode ()  == 200) {         Return true;    }    return false;}

sending a GET request via HttpClient is not written by itself and can be see sending a POST request via httpclient. All right, I'm the lazy one. Take the copy change directly from here. (*^__^*) hehe ...
