angularjs - 绝对 URL 与 ng-src 混淆

Question

所以，我已经用过 ng-src指令，但从不使用绝对图像 URL。现在，我遇到了问题。似乎 Angular 试图将 URL 评估为对我没有任何意义的表达式。

这是标签:

<img ng-src="{{message.logo_url}}" ng-show="{{message.logo_url}}">

这是错误消息:

Error: Syntax Error: Token ':' is an unexpected token at column 5 of the expression [http://m.c.lnkd.licdn.com/mpr/mpr/p/2/000/0ad/2dd/0511c49.png] starting at [://m.c.lnkd.licdn.com/mpr/mpr/p/2/000/0ad/2dd/0511c49.png].

改用这个:

<img ng-src="{{message.logo_url}}" ng-show="message.logo_url">

如 ngShow 中所述的文档。
