I want to use AngularJS in a Chrome extension but I have an error like this:
Error: SECURITY_ERR: DOM Exception 18
Error: An attempt was made to break through the security policy of the user agent.
at new listConnection
manifest.json :
{
"name": "Chrome auditor connection",
"version": "1",
"icons": { "48": "icone.png",
"128": "icone.png" },
"description": "Chrome-auditor-connection is an extension for Google Chrome browser. It ensures that nobody connects to your browser with your profile.",
"background": {
"scripts": [
"chrome_ex_oauthsimple.js",
"chrome_ex_oauth.js",
"background.js"
]
},
"browser_action": {
"default_title": "Chrome auditor connection",
"default_icon": "icone.png",
"default_popup": "index.html"
},
"permissions": [
"storage"
],
"web_accessible_resources": ["index.html"],
"sandbox": {
"pages": ["index.html","index.js","angular.min.js"]
},
"manifest_version": 2
}
index.js :
function listConnection( $scope) {
$scope.connections = JSON.parse(localStorage['connectionHistory']);
}
I think the JSON.parse() is blocked by the Chrome "Content Security Policy" (CSP).
Do you have any solution?

Reset to default 4Your index.js is sandboxed as defined in your manifest.json file.
"A sandboxed page will not have access to extension or app APIs"
So it can't access localstorage.
Remove the sandbox or use something like https://github./jamesmortensen/chrome-sandbox-storageAPI for sandboxed pages.
There are two answers for you:
- Add
ng-cspto your<html>tag, like this<html ng-csp ng-app="AngularAppName">. See this SO answer - Add this line to
manifest.jsonfile
"content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self' "
Problems in your code
These are some of problems i see so far with code shared!.
- Your
index.htmlis being used asdefault_popup,web_accessible_resourcesand insandbox Pages. It is functionally incorrect, what is you want to develop? - Why do you want to put
angular.min.jsin sandbox location? - Is
index.jsused byindex.html, if so there is no need to list it explicitly. - Storage is an object per domain, your
localstoragediffers from sandbox and other pages.
