Android uses the Get and post methods of the HTTP protocol!!!

Just a few days ago, I studied the Get and post requests for the HTTP protocol inside Android:

Android has httpclient can be used to access the interface of the Web page, the following to introduce the use of HttpClient interface,

1.GET:

/** * GET Request * @param path Web path * @param params parameter * @param values of value parameter * @return JSON */Public static string Doget (String path,string[] params,string[] values) {try {HttpClient HttpClient = new Def            Aulthttpclient ();//Create httpclient object String url = urlparamutil.praisegetparams (path, params, values);//Combination page parameters HttpGet httpget = new HttpGet (URL);//Create Get object HttpResponse HttpResponse = Httpclient.execute (httpget);//Open Access, using HttpResponse to collect the returned data//If the connection is successful, read the data if (Httpresponse.getstatusline (). Getstatuscode () = = Httpstatus .        SC_OK) {return ReadData (httpresponse.getentity (). getcontent ());//through HttpResponse to obtain the corresponding output stream}        } catch (Clientprotocolexception e) {e.printstacktrace ();        } catch (IOException e) {e.printstacktrace ();    } return null; /** * Parse URL * @param path PATH * @param params parameter * @param values * @retuRN URL */public static string Praisegetparams (String path,string[] params,string[] values) {string url = ""        ; If params and values are empty, return to path if (params==null| |        values==null) {url = path; }//If the parameters and values differ in size, throw an exception else if (params.length! = values.length) {try {throw new Exce            Ption ("parameter exception");            } catch (Exception e) {e.printstacktrace ();            }}//normal parsing condition else{url = path + "?";            for (int i=0;i<params.length;i++) {URL + = (Params[i] + "=" + Values[i] + "&");        }//Intercept the last character "&" url = url.substring (0, Url.length ()-1);    } return URL;        /** * Read data through byte output stream * @param is * @return JSON */public static String ReadData (InputStream is) { BufferedReader br = new BufferedReader (new InputStreamReader);//convert byte output stream to character output stream StringBuffer sb = new String BuffeR ();        String line = "";            try {line = Br.readline ();                Loop reading data while (line! = null) {Sb.append (line + "\ n");            line = Br.readline ();        }} catch (IOException e) {e.printstacktrace ();    } return sb.tostring (); }

2.POST

/** * POST Request * @param path Web path * @param params parameter * @param values of value parameter * @return JSON */publi C Static String DoPost (String path,string[] params,string[] values) {try {HttpClient HttpClient = new D            Efaulthttpclient (); HttpPost HttpPost = new HttpPost (path);            Create post object//create parameter list<namevaluepair> pairs = Urlparamutil.praisepostparams (params, values);            httpentity entity = new Urlencodedformentity (pairs, "UTF-8");            Httppost.setentity (entity);            HttpResponse HttpResponse = Httpclient.execute (HttpPost); The request successfully starts reading the data if (Httpresponse.getstatusline (). Getstatuscode () = = HTTPSTATUS.SC_OK) {return readd            ATA (Httpresponse.getentity (). getcontent ());        }} catch (Unsupportedencodingexception e) {e.printstacktrace ();        } catch (Clientprotocolexception e) {e.printstacktrace ();   } catch (IOException e) {         E.printstacktrace ();    } return null; }/** * Parse post parameters * @return Pairs */public static list<namevaluepair> Praisepostparams (string[] pa        Rams,string[] values) {list<namevaluepair> pairs = new arraylist<namevaluepair> ();        Namevaluepair pair = null;            Iterate array creation parameters for (int i=0;i<params.length;i++) {pair = new Basicnamevaluepair (Params[i], values[i]);        Pairs.add (pair);    } return pairs; }
