方法从我的应用的网络层消耗我在.NET MVC中创建的Api。我正在进行大量$http.get()调用来调用API端点。当我尝试访问在我的应用程序的应用层中的第一个$http.get()调用上设置的会话数据时，问题就出现了。当我尝试使用另一个$http.get()访问会话数据时，该会话不可用。
在角度控制器中，我这样做：
$http.get()在家庭控制器中我正在做：
$http.get(http://localhost:50033/api/HomeController/SetSessionData)
.then($http.get(http://localhost:50033/api/HomeController/GetSessionData)
.then(//Do Something with sessiondata))
