【问题描述】：
我正在使用 loopback-component-storage 将图像上传到服务器。 https://docs.strongloop.com/display/public/LB/Storage+component
我也有 AngularJS JavaScript SDK，所以我的 lb-services.js 是动态更新的。 https://docs.strongloop.com/display/public/LB/AngularJS+JavaScript+SDK
现在我想在我的网页中显示来自这个环回组件存储模型的照片，称为容器，所以我可以在我的角度控制器方法 getFile（来自 lb-service）中使用，它“获取指定文件中指定文件的信息容器。”像这样：
$scope smthing = Container.getFile({container: 'news-imgs', file: 'smallpic.pnh'})
或者我可以使用“下载指定容器中的文件”的方法下载。像这样：
$scope smthing = Container.download({container: 'news-imgs', file: 'smallpic.png'})
在我的控制器中。
现在，问题是，当我将在.html 文件中写入{{smthing}} 时，第一种方法会显示给我
{
"container": "news-imgs",
"name": "smallpic.png",
"size": 757,
"atime": "2015-12-01T11:49:36.840Z",
"mtime": "2015-12-01T11:49:36.840Z",
"ctime": "2015-12-01T11:49:36.840Z"
}
第二种方法会显示出很多悲伤的迹象，像这样：
"0":"�","1":"P","2":"N","3":"G","4":"\r","5":"\n","6":"\u001a","7":"\n","8":"\u0000","9":"\u0000","10":"\u0000","11":"\r","12":"I","13":"H","14":"D","15":"R","16":"\u0000","17":"\u0000","18":"\u0000","19":"\u0014","20":"\u0000","21":"\u0000","22":"\u0000","23":"\u0012","24":"\b","25":"\u0003","26":"\u0000","27":"\u0000","28":"\u0000","29":"l","30":"\u000e","31":"\u000e","32":"\"","33":"\u0000","34":"\u0000","35":"\u0000","36":"\u0019","37":"t","38":"E","39":"X","40":"t","41":"S","42":"o","43":"f","44":"t","45":"w","46":"a","47":"r","48":"e","49":"\u0000","50":"A","51":"d","52":"o","53":"b","54":"e","55":" ","56":"I","57":"m","58":"a","59":"g","60":"e","61":"R","62":"e","63":"a","64":"d","65":"y","66":"q","67":"�","68":"e","69":"<","70":"\u0000","71":"\u0000","72":"\u0001","73":"�","74":"P","75":"L","76":"T","77":"E","78":"�","79":"�","80":"�","81":"�","82":"�","83":"�","84":"�","85":"\u0000","86":"r","87":"�","88":"�","89":"�","90":"�","91":"\u0000","92":"�","93":"�","94":"\u0000","95":"~","96":"�","97":"�","98":"�","99":"�","100":"\u0000","101":"x","102":"�","103":"\u0012","104":"�","105":"�","106":"\u0000","107":"","108":"�","109":"\t","110":"�","111":"�","112":"\u0016","113":"{","114":"�","115":"\u0002","116":"�","117":"�","118":"(",...etc
我认为它是 Image 对象，但在 json 中，对吧？
我也尝试将{{smthing}} 扔到<img src=""> 标记和<img ng-src="">，但它也不起作用。
问题是：如何显示这张照片？ 有人可以帮帮我吗？
你好，艾伦。
【问题讨论】：
-
为什么不在base64中encore你的图像然后显示它？
-
我真的不知道该怎么做。如果我将在 base64 中添加我的图像，那么我会得到什么？以及如何显示它？在 标签中，或者就像 {{smthing}} ??
-
如果你用 base64 编码你的图像，它会返回一个字符串。然后你只需要写一些类似
<img src="data:image/png;base64,{{base64string}}">的东西你就可以了解更多here。 -
我认为这会有所帮助，我现在会尝试走这条路。 ;)
-
看上面的输出。我应该先将其转换为字符串，然后使用 angular-base64？
