所以，在大约 1 小时内，我的扩展就失败了。
我正在做我的扩展，它正在做我假装的事情。我做了一些更改，因为我不喜欢我删除了它们，现在我的扩展程序抛出错误:
Refused to apply inline style because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'style-src' was not explicitly set, so 'default-src' is used as a fallback.
是什么导致了这个错误？
我做了我的改变:
popup.html
<!DOCTYPE html>
<html ng-app="PinIt" ng-csp>
<head>
<link rel="stylesheet" href="css/popup.css">
<script src="js/lib/jquery-1.8.2.min.js"></script>
<script src="js/lib/angular.min.js"></script>
<script src="js/app/app.js"></script>
<script src="js/app/popup.js"></script>
</head>
<body id="popup">
<header>
<h1>PinIt</h1>
</header>
<div ng-controller="PageController">
<div>{{message}}</div>
<h2>Page:</h2>
<div id="elem">{{title}}</div>
<div>{{url}}</div>
<h2>Imagens:</h2>
<ul>
<li ng-repeat="pageInfo in pageInfos" style="list-style: none">
<div class="imgplusshare">
<img src={{pageInfo}} class="imagemPopup" />
<ul class="imas">

</html>
popup.js
myApp.service('pageInfoService', function() {
this.getInfo = function(callback) {
var model = {};
chrome.tabs.query({
'active': true
},
function(tabs) {
if (tabs.length > 0) {
model.title = tabs[0].title;
model.url = tabs[0].url;
chrome.tabs.sendMessage(tabs[0].id, {
'action': 'PageInfo'
}, function(response) {
model.pageInfos = response;
callback(model);
});
}
});
};
});
myApp.controller("PageController", function($scope, pageInfoService) {
pageInfoService.getInfo(function(info) {
$scope.title = info.title;
$scope.url = info.url;
$scope.pageInfos = info.pageInfos;
$scope.fbshare = function($src) {
chrome.windows.create({
url: "http://www.facebook.com/sharer/sharer.php?u=" + $src
});
};
$scope.twshare = function($src) {
chrome.windows.create({
url: "https://twitter.com/intent/tweet?url=" + $src
});
};
$scope.gpshare = function($src) {
chrome.windows.create({
url: "https://plus.google.com/share?url=" + $src
});
};
$scope.mailshare = function($src) {
chrome.windows.create({
url: "mailto:?subject=Imagem Partilhada por PinIt&body=<img src=\"" + $src + "\"\\\>"
});
};
$scope.$apply();
});
});
这是我的 list 文件:
{
"name": "PinIt",
"version": "1.0",
"manifest_version": 2,
"description": "Pin It",
"icons": {
"128": "icon128.png"
},
"browser_action": {
"default_icon": "img/defaultIcon19x19.png",
"default_popup": "popup.html",
"default_title": "PinIt"
},
"content_scripts": [{
"js": ["js/lib/jquery-1.8.2.min.js", "js/app/content.js", "js/jquery-ui-1.10.3.custom.js"],
"matches": ["*://*/*"],
"run_at": "document_start"
}],
"minimum_chrome_version": "18",
"permissions": ["http://*/*", "https://*/*", "unlimitedStorage", "contextMenus", "cookies", "tabs", "notifications"],
"content_security_policy": "default-src 'self'"
}
有什么建议吗？
最佳答案
您还可以通过添加 style-src 'self' 'unsafe-inline';
"content_security_policy": "default-src 'self' style-src 'self' 'unsafe-inline';"
这将允许您在扩展中继续使用内联样式。
重要提示
正如其他人指出的那样，不推荐这样做，您应该将所有 CSS 放在一个专用文件中。查看OWASP explanation关于为什么 CSS 可以成为攻击的媒介(感谢 @KayakinKoder 提供的链接)。
