loopback-storage-component如何显示图片文件

提问于

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

我还有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此环回组件存储模型的照片，称为容器，因此我可以在我的角度控制器方法getFile（来自lb-service）中使用，其中“获取指定容器内指定文件的信息” . 像那样：

$scope smthing = Container.getFile({container: 'news-imgs', file: 'smallpic.pnh'})

或者我可以使用方法下载，即“在指定容器中下载文件” . 像那样：

$scope smthing = Container.download({container: 'news-imgs', file: 'smallpic.png'})

在我的控制器中 .

现在，问题是，当我写入.html文件 {{smthing}} 时，第一种方法会告诉我

{ "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" }

而第二种方法将显示如此多的悲伤迹象，如下所示：

"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

我认为这是Image对象，但在json中，对吗？

我也试图将 {{smthing}} 扔到 <img src=""> 标签和 <img ng-src=""> ，但它也不起作用 .

问题是：如何显示这张照片？请问有人可以帮助我吗？

问候，艾伦 .

    无需转换为 base64 即可显示图像 . 只是使用这个技巧 .

    假设您的 container Name 和 Image Name 是

    • Container Name = news-imgs

    • File Name = smallpic.png

    Then download link would be like

    /api/containers/news-imgs/download/smallpic.png

    这意味着您可以通过以下方式准备下载链接

    /api/container/Your-Container-Name/download/Your-File-Name

    在您的视图中，您可以显示图像

    <img ng-src="/api/container/Your-Container-Name/download/Your-File-Name" />

<img ng-src="/api/containers/news-imgs/download/smallpic.png" />

    Now use Angular to generate download link dynamically for each images.
