“找不到内容安全策略元标签”。错误在我的phonegap应用程序 [英] "No Content-Security-Policy meta tag found." error in my phonegap application

问题描述

更新Cordova 5.0在我的系统中，我创建新的应用程序。当我在设备上测试我的应用程序时，我在控制台日志中收到错误：

After update Cordova 5.0 in my system I create new applications. When I tested my application in device that time I get an error in the console log:

No Content-Security-Policy meta tag found.
Please add one when using the Cordova-plugin-whitelist plugin.: 23.

在头部添加元

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src: 'self' 'unsafe-inline' 'unsafe-eval'>

但是，同样的，我在应用程序中使用了inappbrowser插件和其他7个网站链接。

But again, I got the same error, in my application I use inappbrowser plugin and 7 of other website links.

推荐答案

添加 cordova-plugin-whitelist 后，您必须告知应用程序

After adding the cordova-plugin-whitelist, you must tell your application to allow access all the web-page links or specific links, if you want to keep it specific.

您可以简单地将它添加到您的 config.xml ，可在应用程序的根目录中找到：

You can simply add this to your config.xml, which can be found in your application's root directory:

推荐：

<allow-navigation href="http://example.com/*" />

或：

<allow-navigation href="http://*/*" />

从插件的文档：

导航白名单

控制可以导航到WebView本身的URL。仅适用于
顶级导航。

Controls which URLs the WebView itself can be navigated to. Applies to top-level navigations only.

Quirks：在Android上，它也适用于非http（s）方案的iframe。

Quirks: on Android it also applies to iframes for non-http(s) schemes.

默认情况下，只允许导航到file：// URLs。要允许
其他其他URL，您必须向您的
config.xml中添加标签：

By default, navigations only to file:// URLs, are allowed. To allow other other URLs, you must add tags to your config.xml:

<!-- Allow links to example.com -->
<allow-navigation href="http://example.com/*" />

<!-- Wildcards are allowed for the protocol, as a prefix
     to the host, or as a suffix to the path -->
<allow-navigation href="*://*.example.com/*" />

<!-- A wildcard can be used to whitelist the entire network,
     over HTTP and HTTPS.
     *NOT RECOMMENDED* -->
<allow-navigation href="*" />

<!-- The above is equivalent to these three declarations -->
<allow-navigation href="http://*/*" />
<allow-navigation href="https://*/*" />
<allow-navigation href="data:*" />
