OKHTTP3 's use, the actual combat experience of their own projects

okhttp3.0 on-line information is too little, today I come to write a okhttp3.0 for you to use

A lot of builder was introduced into the okhttp3.0.

1. Create okhttpclient builder

private static final OKHTTP3. Okhttpclient.builder Builder = new Okhttpclient.builder ();

2. Create an instance of Okhttpclient

Setting the time-out setting cookies cache

Mokhttpclient=builder.connecttimeout (timeunit.seconds). Cookiejar (New Cookiesmanager ()). build ();

Private class Cookiesmanager implements Cookiejar  {            private final persistentcookiestore Cookiestore = new Persistentcookiestore (context);        @Override public        void savefromresponse (httpurl url, list<cookie> cookies) {            if (cookies! = null && Cookies.size () > 0) {                for (Cookie item:cookies) {                    cookiestore.add (URL, item);        }}} @Override public        list<cookie> loadforrequest (httpurl url) {            list<cookie> cookies = Cookiestore.get (URL);            return cookies;        }    }

3. Using OkHttpClient3.0

Get Request Object

  private static Request getprarequest (String url,string name) {  Builder builder=  new Formbody.builder (). Add (" Name ", name); Form <span style= "font-family:arial, Helvetica, Sans-serif;" >//through Request.builder () to build () an instance </span>

             return new Request.builder (). URL (URL). Post (Builder.build ()). build (); }

Request URL

Mokhttpclient.newcall (getprarequest (URL, name)). Enqueue (Responsecallback);

getprarequest (URL, name) get a request Responsecallback Callback event is the interface of Callback

public void Onresponse (call arg0, Final Response arg1) throws IOException {if (arg1.issuccessful ()) {try{onsuccess (new Jsonobject (Arg1.body (). String ()));} catch (Jsonexception e) {onfailure ("JSON parsing exception"); E.printstacktrace ();}            Onloginsuccess (null, arg1);} else{           onfailure ("Request failed, return code" + "Arg1.code ()");  System.out.println (Arg1.code () + "");}}

Two categories of cookies

public class Persistentcookiestore {private static final String Log_tag = "Persistentcookiestore";    private static final String cookie_prefs = "Cookies_prefs";    Private final map<string, concurrenthashmap<string, cookie>> cookies;    Private final sharedpreferences cookieprefs;        Public Persistentcookiestore (Context context) {cookieprefs = context.getsharedpreferences (cookie_prefs, 0);        cookies = new hashmap<string, concurrenthashmap<string, cookie>> ();        Cache persistent cookies in memory as Map cookies map<string,?> prefsmap = Cookieprefs.getall (); For (map.entry<string,?> entry:prefsMap.entrySet ()) {string[] Cookienames = Textutils.split ((String)            Entry.getvalue (), ",");                for (string name:cookienames) {string encodedcookie = cookieprefs.getstring (name, NULL);        if (Encodedcookie! = null) {Cookie Decodedcookie = Decodecookie (Encodedcookie);            if (Decodedcookie! = null) {if (!cookies.containskey (Entry.getkey ())) {                        Cookies.put (Entry.getkey (), New concurrenthashmap<string, cookie> ());                    } cookies.get (Entry.getkey ()). Put (name, Decodedcookie); }}}}} protected String Getcookietoken (cookie cookie) {return Cookie.nam    E () + "@" + cookie.domain ();        } public void Add (httpurl url, cookie cookie) {String name = Getcookietoken (cookie);                Cache cookies in memory if the cache expires, reset this cookie if (!cookie.persistent ()) {if (!cookies.containskey (Url.host ())) {            Cookies.put (Url.host (), New concurrenthashmap<string, cookie> ());        } cookies.get (Url.host ()). Put (name, cookie);            } else {if (Cookies.containskey (Url.host ())) {Cookies.get (Url.host ()). Remove (name);     }   }//Tell the cookie to persist to local sharedpreferences.editor Prefswriter = Cookieprefs.edit ();        Prefswriter.putstring (Url.host (), Textutils.join (",", Cookies.get (Url.host ()). KeySet ());        Prefswriter.putstring (Name, Encodecookie (new Serializableokhttpcookies (cookie)));    Prefswriter.apply ();        } public list<cookie> get (httpurl URL) {arraylist<cookie> ret = new arraylist<cookie> ();        if (Cookies.containskey (Url.host ())) Ret.addall (Cookies.get (Url.host ())). values ());    return ret;        } public boolean RemoveAll () {Sharedpreferences.editor prefswriter = Cookieprefs.edit ();        Prefswriter.clear ();        Prefswriter.apply ();        Cookies.clear ();    return true;        } public boolean remove (httpurl URL, cookie cookie) {String name = Getcookietoken (cookie); if (Cookies.containskey (Url.host ()) && Cookies.get (Url.host ()).

I don't know how to comment.
