Question

我一直在尝试从interceptorService（file：authenticationServices.js）调用UserService.openLogin（）函数，但我没有成功。

一切正常，但是当我尝试将UserService作为依赖项注入时，在interceptorService中，AngularJS会返回以下错误：

“未捕获错误：[$ injector：cdep]找到循环依赖关系：$ http＆lt; - UserService＆lt; - interceptorService＆lt; - $ http＆lt; - $ templateRequest＆lt; - $ compile”。

拜托，有人可以帮助我吗？

我找到了一种方法来注入UserService而没有循环依赖性错误。但我不知道是否正确。有人知道吗？

查看临时解决方案：

 public partial class Form1 : Form
 {
    public Form1()
    {

        InitializeComponent();
        PlaceList.Combo_list = comboBox1;


    }
 }

AngularJS中的循环依赖
