java - Play Framework - Ajax web service call image request issue -


i have developed web service using play framework. have created post rest service in play framework below.

in routes file:

post    /imageupload        controllers.application.imageupload()

in application.java:

public static result imageupload() {     objectnode result = json.newobject();      multipartformdata body = request().body().asmultipartformdata();     filepart file = body.getfile("file");     file trainimg = file.getfile();     file temp = new file("/play_framework/temp.jpg");     trainimg.renameto(temp);// moved image folder check correct image.      .     .     .      return ok(result); }

in service, have written code save image received request. have called service ajax given below.

in index.html file:

var formdata = new formdata(); var blob = new blob([imagedata], { type: "image/jpg"}); formdata.append("file", blob, "capturedimage.jpg");  $.ajax({        url: 'http://localhost:9000/imageupload',        data: formdata,        crossdomain: true,        processdata: false,        contenttype: false,        async: false,        cache: false,        datatype: "json",        type: 'post',        success: function(data){             alert(data);             var responsestr = json.stringify(data);                 alert("response str -- "+responsestr);        }        });

when upload file multipart form data, can receive multipart data in server side. stored "multipartbody7906599875117091855astemporaryfile".

if file's mimitype - "content/unknown".

when debug, got below multipart form data path "/var/folders/f3/r3rfqfl949z5pf2cprwn95dm0000gn/t/multipartbody7906599875117091855astemporaryfile".

how parse "jpg" file? can me this?

the following worked me:

application.java

public class application extends controller {      public static result index() {         return ok(index.render("so answer 30229421"));     }      public static result imageupload() {         objectnode result = json.newobject();          http.multipartformdata body = request().body().asmultipartformdata();         http.multipartformdata.filepart file = body.getfile("file");         file trainimg = file.getfile();         file temp = new file("/tmp/temp.jpg");         trainimg.renameto(temp); // moved image folder check correct image.          result.put("path", temp.getabsolutepath());         return ok(result);     }      public static result imagedownload(string path) {         return ok(new file(path));     }

index.scala.html

@(message: string)  <html> <body>     <h1>@message</h1>     <input type="file" id="imagedata"/>     <button onclick="send()">send image</button>      <div id="image">     </div>      <script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>     <script>      function send() {         var imagedata = $('#imagedata')[0].files[0];          var formdata = new formdata();         var blob = new blob([imagedata], { type: "image/jpg"});         formdata.append("file", blob, "capturedimage.jpg");          $.ajax({                url: 'http://localhost:9000/imageupload',                data: formdata,                crossdomain: true,                processdata: false,                contenttype: false,                async: false,                cache: false,                datatype: "json",                type: 'post',                success: function(data){                     $('#image').html('<img src="http://localhost:9000/imagedownload?path=' + data.path + '"/>');                }        });     }     </script>  </body> </html>

the difference, because didn't include how imagedata value, used version (as per so answer):

var imagedata = $('#imagedata')[0].files[0];

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
