我看着Chrome上的網絡標籤，發現我的元數據微風API沒有被調用，因此我所有的createEntity等方法都失敗了。微風元數據Api沒有被調用
[HttpGet]
public string Metadata()
{
return _context.Metadata();
}
我都跟着待辦事項例子並啓用CORS支持和剛纔的一切，我可以看到JSON元數據，如果我瀏覽到/ API /微風/元 我使用VS2012的Web Express和得到的所有包通的NuGet dataservice.js
app.dataservice = (function (breeze) {
var serviceName = 'api/breeze'; // route to the same origin Web Api controller
var manager = new breeze.EntityManager(serviceName);
return {
createTodo: createTodo,
saveChanges: saveChanges
};
function createTodo(initialValues) {
return manager.createEntity('BreezeItem', initialValues);
}
function saveChanges() {
return manager.saveChanges()
.then(function() { alert('good') })
.fail(function() { alert('bad') })
}
})(breeze);
