How to get unwrapped value of object that wrapped with $sce?
提问by ali
In my web application I given an object that is wrapped with angular $sce.In this object each property has a special property $$unwrappedTrusted but it doesn't really give me the object value.How I can get trusted value of object property?
在我的 web 应用程序中，我给出了一个用 angular $sce 包裹的对象。在这个对象中，每个属性都有一个特殊的属性 $$unwrappedTrusted 但它并没有真正给我对象值。我如何获得对象属性的可信值？

As @rrhrg said properties start with $$ considered as private and not safe to use. Better use valueOf method of $sce service.
正如@rrhrg 所说，以 $$ 开头的属性被认为是私有的，使用起来不安全。更好地使用 $sce 服务的 valueOf 方法。
var trustedResource = $sce.trustAsResourceUrl("www.abcd.com/folder/image.png");
$sce.valueOf(trustedResource); // "www.abcd.com/folder/image.png"

You can use the getTrustedHtml() function. This gets the html string value from $$unwrapTrustedValue.
您可以使用 getTrustedHtml() 函数。这从 $$unwrapTrustedValue 获取 html 字符串值。
vm.user.bio = $sce.getTrustedHtml(vm.user.bio);
You may also need to include ngSanitize.
您可能还需要包含ngSanitize。

If I understood your question correctly, you would like to unwrap (or use?) a value wrapped by angular's service $sec.
如果我正确理解了您的问题，您想解开（或使用？）由 angular 的 service 包装的值$sec。
To use such a value in your html document, you can use the directive ng-bind-html.
要在您的 html 文档中使用这样的值，您可以使用指令ng-bind-html。
<div ng-bind-html="myWrappedValue"></div>
To unwrap such a value, you may use the function $$unwrapTrustedValue().
要解开这样的值，您可以使用函数$$unwrapTrustedValue()。
$sce.trustAsHtml('©').$$unwrapTrustedValue() === '©'
Please notethat properties which start with two dollar signs ($$) are considered as private and should NOTbe accessed!
请注意，这两个美元符号（$$）被认为是私人的开端，应该是性质不被访问！

I get value of each property by calling toString() function but I did not found any method that help me to find object itself.
我通过调用 toString() 函数来获取每个属性的值，但是我没有找到任何可以帮助我找到对象本身的方法。
