AugularJS通过服务器请求图片时总是报错 [$interpolate:noconcat]

Question

图片是通过服务器请求得到的,PHP测试正确，页面也是通过服务器端打开的，同样请求的其他数据文字之类的没有错误，可以正常显示，就只是图片出错，当单独测试的时候会出现图片详情，代码截图如下：

当代码是如下情况的时候，就会报错：

当注释掉img所在行的时候，其他数据正常显示

报错浏览器控制台错误代码如下：
angular.js:12314 Error: [$interpolate:noconcat] Error while interpolating: img/{{dish.img_sm}}
Strict Contextual Escaping disallows interpolations that concatenate multiple expressions when a trusted value is required. See http://docs.angularjs.org/api...$sce

Answer 1

这个是插值出现了连接错误，你试下<img ng-src="{{'img/' + dish.img_sm}}">，这样就可以了。

Answer 2

你审查一下图片的路径看看是否正确

Answer 3

<img ng-src="'img/' + {dish.img_sm}">
