所以，我已经使用了ng-src指令，但从未使用过绝对图像URL。现在我有问题了。Angular似乎试图将URL评估为一个对我来说毫无意义的表达式
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].

如果你还需要什么，请告诉我。
改为使用这个：
<img ng-src="{{message.logo_url}}" ng-show="message.logo_url">
如ngShow文件中所述。
