Vuex MutationAction 装饰器不可分配给 TypedPropertyDescriptor

问题描述

我是 Typescript 的新手，如果这是新手问题，请提前抱歉。

我不知道如何解决这个 TS 错误：

@Module({ namespaced: true,name: "Admin" })
class Admin extends VuexModule {
  public adminUserList: UserList = [];

  @MutationAction({ mutate: ["adminUserList"] })
  async getAdminUserList(): Promise<Record<string,UserList>> {
    const req = (await Utils.async({
      data: adminUserList,})) as Record<string,UserList>;

    return {
      adminUserList: req.data as UserList,};
  }
}

解决方法

好的，所以我只需要更改操作的返回类型。

@Module({ namespaced: true,name: "Admin" })
class Admin extends VuexModule {
  public adminUserList: UserList = [];

  @MutationAction({ mutate: ["adminUserList"] })
  async getAdminUserList(): Promise<Record<"adminUserList",UserList>> {
    const req = (await Utils.async({
      data: adminUserList,})) as Record<string,UserList>;

    return {
      adminUserList: req.data as UserList,};
  }
}
