        // http.HandleFunc("/onlyme", onlyme)
        http.ListenAndServe(":8801", nil) // server runs at this port
    }


    func Homepage(w http.ResponseWriter, r *http.Request) {
        NamespaceStruct := NamespaceDetails{}
        for _, Namespaces := range NamespaceClient.Items {
            log.V(5).Info("inside namespace items loop in homepage")
            NamespaceStruct.Namespace = append(NamespaceStruct.Namespace, Namespaces.Name)
        }
                templates.ExecuteTemplate(w, "homepage2.html", NamespaceStruct)
    }

    func deployments(namespace string)(*"k8s.io/api/apps/v1".DeploymentList, error){
        return  clientset.AppsV1().Deployments(namespace).List(v1.ListOptions{})
    }

当我尝试运行此代码时，它给出了错误：

语法错误：意外文字“k8s.io/api/apps/v1”，预期类型

我想使用 deploymnets 函数返回部署列表。我不知道要使用什么返回类型，以便我成功返回部署列表。

在导入中添加这一行

v2 "k8s.io/api/apps/v1"

并更新函数参数如下

func deployments(namespace string)(*v2.DeploymentList, error){

如果你在寻找 podslist/namespacelist

import  v3 "k8s.io/api/core/v1"

和更新功能为，

 func func_name (input paramteters)(*v3.NamespaceList/PodList , error){

这是无效的语法：

func deployments(namespace string)(*"k8s.io/api/apps/v1".DeploymentList, error){

这是正确的语法：

func deployments(namespace string)(*v1.DeploymentList, error){

但是，您已经v1导入了另一个包，因此您必须使用不同的别名导入该包，并使用该名称，
