javascript - cross domain ajax call in chrome extension -

-

i making small extension test apis. while making ajax calls throughs error. 

 refused load script 'http://localhost:8080/acton-demouser/user1?callback=jquery2210009971836116164923_1456851818933&format=json&_=1456851818934' because violates following content security policy directive: "default-src 'self' blob: filesystem: chrome-extension-resource:". note 'script-src' not explicitly set, 'default-src' used fallback.

while ajax call url : http://localhost:8080/acton-demouser/user1

manifest.json :

{   "name": "ajax helper",   "version": "1.0",   "description": "my first chrome extension.",   "manifest_version": 2,   "browser_action": {     "default_icon": "icon.png",     "popup": "popup.html",     "default_popup": "popup.html"   },   "app": {     "background": {       "scripts": ["background.js"]     }   },   "icons": { "16": "icon.png", "128": "icon.png" },   "content_security_policy": "script-src 'self' https://ajax.googleapis.com; object-src 'self'",   "permissions": [     "http://*/*"   ] }

js file :-

$("form").submit(function(){     var ajaxtype = $('#request-method-selector option:selected').val();     var urlprefix = 'http://localhost:8080/acton-demo';     var url = $('#url').val();     if(ajaxtype === 'get'){         $.ajax({             url: (urlprefix+url),             error: function() {                     $('#error').html('<p>an error has occurred</p>');                 },             datatype: 'jsonp',             success: function(data) {                         $("#success").html(data);                     },             type: 'get'         });     }  });

what missing here.

you need specify 'http://localhost:8080' content_security_policy definition whitelist. because you're using 'jsonp' datatype @ calling endpoint $.ajax. is, not ajax calling, script tag creation. therefore, have add domain content_security_policy definition.

"content_security_policy": "script-src 'self' http://localhost:8080 https://ajax.googleapis.com; object-src 'self'",

basically, can specify urls has 'https' prefix only. however, easy development, allows specify 2 domains 'http://localhost' , 'http://127.0.0.1'. described in document.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
