Okhttp-based Asynchronous requests

Take the time to encapsulate a okhttp-based network request, just encapsulate the get,post, download,upload request, do not need to create a thread, support JSON automatic conversion.

Get and post (file upload also belongs to post) are divided into two main steps:

1. Create the request entity object through Httprequestbuilder.

2. Send the request via the Httputil SendRequest method, and use Resultcallback to accept the return content, which automatically converts the JSON to an entity when successful in this step, and the OnError method of Resultcallback If the failure is performed , and pass HttpException, which contains HTTP error codes, such as 404,500.

Get Request Method:

private void Getsample () {HttpRequest request = new Httprequestbuilder (). URL (URL). AddHeader ("Cookie", "DF"). Addparams ( "Key", "value"). Method (Httpmethod.get). build (); Httputil.getinstance (). SendRequest (Request, new resultcallback<result> () {@Overridepublic void Onresponse ( Result response) {//TODO auto-generated method Stubtextview.settext (Response.getdata (). GetName ());} @Overridepublic void OnError (Request request, HttpException HttpException) {//TODO auto-generated method Stubtextview.settext ("Requestcode:" +httpexception.getresponsecode () + "errormessage:" +httpexception.getmessage () );}});}

POST request:

private void Postsample () {HttpRequest request = new Httprequestbuilder (). URL ("http://www.oschina.net/action/user/ Hash_login "). AddHeader (" Cookie "," DF "). Addparams (" email "," xxxxxxxxx "). Addparams (" pwd "," xxxxxxxxxxxxxxxxx "). Method (Httpmethod.post). build (); Httputil.getinstance (). SendRequest (Request,new resultcallback<string> () {@Overridepublic void OnError ( Request request,httpexception httpexception) {//TODO auto-generated method stub} @Overridepublic void Onresponse (String Response) {//TODO auto-generated Method Stubtextview.settext (response);}});}

File Upload:

private void Fileuploadsample () {if (! Textutils.isempty (Textview.gettext ())) {File File = new file (Textview.gettext (). toString ()); final String URL = "Server address ... "; HttpRequest request = new Httprequestbuilder (). URL (URL). Method (Httpmethod.post). AddFile (new filediscription (file). Setuploadprograsslistener (Fileuploadlistener)). Build (); Httputil.getinstance (). SendRequest (Request,new resultcallback<string> () {@Overridepublic void OnError ( Request request,httpexception httpexception) {//TODO auto-generated method stub} @Overridepublic void Onresponse (String Response) {//TODO auto-generated Method Stubtextview.settext (response);}});}}

The file download is a GET request, but instead of using Resultcallback, Downloadcallback is used to listen for download progress, complete and failed callbacks. The code is as follows:

private void DownLoad () {HttpRequest request= new Httprequestbuilder (). URL ("http://img.taopic.com/uploads/allimg/ 130501/240451-13050106450911.jpg "). Method (Httpmethod.get). Downloadpath (FilePath, string.valueof (New Date (). GetTime ()) + ". jpg"). Build (); Httputil.getinstance (). DownLoad (Request, new Downloadcallback () {@Overridepublic void ondownloading (int prograss) {// TODO auto-generated Method Stubtextview.settext (prograss+ "%");p rogressbar.setprogress (Prograss);} @Overridepublic void Ondownloadsuccess () {//TODO auto-generated method Stubtextview.settext ("Down load Success");} @Overridepublic void Ondownloadfail (HttpException ex) {//TODO auto-generated method Stubtextview.settext ( Ex.getmessage ());});}
