javascript - How to not repeat folders with JStree? -


i have json file data this:

datatree.json =   [     {         "datap": "816816816816816818",         "name": "image1.jpg",         "url": "/files/folder1/test/d2e9c54ceedc9/image1.jpg",         "path": "/files/folder1/test/image1.jpg",         "size": 35969     },      {         "datap": "857022de4fccdcb54623ff6185daae706a47140c",         "name": "image2.jpg",         "url": "/files/folder1/pruebas/85623ff6185d7140c/image2.jpg",         "path": "/files/folder1/pruebas/image2.jpg",         "size": 17689282     },     {         "datap": "b260ec3250420c953a9db41897c34e3551620ec325035516256b2/image3.jpg",         "path": "/files/folder1/test/image3.jpg",         "size": 710632     } ]

in part make operation , format jstree

$.getjson('/datatree.json', function (response) {             var fulltree = [];             if (response == []){                 var refulltree = []             }              else {                  var refulltree = [{"id":null,"text":"root","icon":"tree.png","state":null,"children":[]}]             }              function treeelements(element, tree){                 var parts = element.path.split("/");                 parts.splice(0,2);                 (var k in parts) {                     var count = 0                     var part = parts[k];                     if (part == "") part = "#";                     var item = {"id":null, "text": part, "icon": icon(part), "children": []};                     tree.push(item);                     tree = item.children;                  }                   function icon(search){                     if (search.indexof(".png",".jpg") > -1){                          return "glyphicon glyphicon-picture" }                     else if(search.indexof("jpg",".jpg") > -1){                          return "glyphicon glyphicon-picture" }                 }              }              (var in response) {                 treeelements(response[i], fulltree);              }             refulltree[0]["children"] = fulltree  });

the result output in format:

[     {     "id": null,     "text": "root",     "icon": "tree.png",     "state": null,     "children": [         {         "id": null,         "text": "folder1",         "children": [         {         "id": null,         "text": "test",             "children": [              {                 "id": null,                 "text": "image1.jpg",                 "icon": "glyphicon glyphicon-picture",                 "children": []              }             ]          }       ]   },  {     "id": null,     "text": "folder1",     "children": [       {         "id": null,         "text": "pruebas",         "children": [           {             "id": null,             "text": "image2.jpg",             "icon": "glyphicon glyphicon-picture",             "children": []           }         ]       }     ]   },   {     "id": null,     "text": "folder1",     "children": [       {         "id": null,         "text": "test",         "children": [           {             "id": null,             "text": "image3.jpg",             "icon": "glyphicon glyphicon-picture",             "children": []           }         ]       }     ]   } ] } ]

this tree produced jstree, , 3 folders have same name. not want create 3 folders same name, want when find folder exists, data entered existing folder.

current tree diagram

instead, want this:

desired tree diagram

here demo of how parse structure: http://jsfiddle.net/dgaf4/506/

here actual parsing code (also visible in fiddle);

var tmp = {}, i, j, k, l, p1, p2, fin = []; for(i = 0, j = a.length; < j; i++) {     p1 = a[i].path.replace(/^\//,'').split('/');     p2 = '';     for(k = 0, l = p1.length; k < l; k++) {         tmp[p2 + '/' + p1[k]] = {             id : p2 + '/' + p1[k],              parent : p2 ? p2 : '#',              text : p1[k]         };         p2 += '/' + p1[k];     }     for(k in a[i]) {         if(a[i].hasownproperty(k)) {             tmp[a[i].path][k] = a[i][k];         }     }     if(a[i].path.match(/(jpg|png|jpeg)$/)) {         tmp[a[i].path].icon = "glyphicon glyphicon-picture";     } } for(i in tmp) {     if(tmp.hasownproperty(i)) {         fin.push(tmp[i]);     } } // fin contains structure in jstree compatible format

apache - PHP Soap issue while content length is larger -

we have developed soap based webservice post data third party webservice. accepts 4 params. in 1 of parameters accepts xml string no size limit restriction put in place. the webservice works fine in local environment running on php 5.2 , apache2. works content length long 10 mb. in staging server running nginx , php fpm.we have updated max post size , max upload filesize in php.ini , client_max_body param in nginx.conf allow upto 50 mb. but webservice client keeps on loading in staging environment. gives 502 timeout , gives soap error. can me understand issue here?

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: { ...
