Incrustar un documento de Word Word aleatorio, que encontré en Internet, funciona si codifico la URL:

<iframe src="http://docs.google.com/gview?url=https://d9db56472fd41226d193-1e5e0d4b7948acaf6080b0dce0b35ed5.ssl.cf1.rackcdn.com/spectools/docs/wd-spectools-word-sample-04.doc&embedded=true"></iframe>

Sin embargo, quiero obtener la URL por AJAX, así que cambié el HTML a

<iframe src="{{cvUrl}}&embedded=true"></iframe> 

pero incluso codificando eso$scope variable en mi JS:

$scope.cvUrl = 
    'http://docs.google.com/gview?url=https://d9db56472fd41226d193-1e5e0d4b7948acaf6080b0dce0b35ed5.ssl.cf1.rackcdn.com/spectools/docs/wd-spectools-word-sample-04.doc';

Esto parece bastante básico: ¿qué estoy haciendo mal?
