Why is this happening? 为什么会这样呢? My app also crashed frequently with message "your app stopped workign unfortunately" 我的应用也经常崩溃,并显示消息“很遗憾,您的应用停止了工作”
The whitelist can allow/block network requests to/from certain protocols (eg, HTTP/HTTPS) from the WebView which Cordova provides ( UIWebView
for iOS and WebView
for Android). 白名单可以允许/禁止网络的请求到/从从中科尔多瓦提供(web视图某些协议(例如,HTTP / HTTPS) UIWebView
iOS和WebView
为Android)。
However, it cannot filter all types of requests ( <video>
, <media>
, sockets as an example), so the Content-Security-Policy
is required to filter this. 但是,它不能过滤所有类型的请求(例如<video>
, <media>
,套接字),因此需要Content-Security-Policy
进行过滤。
This is controlled via a meta tag in your HTML file(s): 这是通过HTML文件中的meta标记控制的:
<!-- Good default declaration:
* gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
* Disables use of eval() and inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src
* Enable eval(): add 'unsafe-eval' to default-src
-->
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com; style-src 'self' 'unsafe-inline'; media-src *">
<!-- Allow requests to foo.com -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self' foo.com">
<!-- Enable all requests, inline styles, and eval() -->
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">
<!-- Allow XHRs via https only -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self' https:">
<!-- Allow iframe to https://cordova.apache.org/ -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; frame-src 'self' https://cordova.apache.org">

Edit: as for your question on why your app keeps crashing, I cannot determine why with the information provided so I will need a little more info. 编辑:关于您的应用程序为什么继续崩溃的问题,我无法确定提供的信息的原因,因此我需要更多信息。
It isn't related to the Content-Security-Policy
though. 它与Content-Security-Policy
无关。
Maybe some Android/iOS logs would help. 也许一些Android / iOS日志会有所帮助。
