javascript - vue-router开启HTML5的history模式后,点击可以正常跳转,但是一刷新就404,何解?

我是用vue-cli来构建的项目,使用了vue-router来做路由,如果使用 "hash"模式,随便怎么点击,或者刷新都是正常的,但是使用history模式,点击是可以正常跳转,但是页面一刷新就报404 找不到.

这是index页面报错,很奇怪的是,那个路径里的main是我配置的路由,不知道为什么那个main路由会添加到我的index页面里的引入地址里.
下面是我的index.html页面的代码

    let router = new VueRouter({
        mode: "history",
        // base: '../',
        routes: [
            {
                path: "/", component: logincomponent, name: "login",
                meta: {requiresAuth: true}
            },
            {
                path: "/main", component: appcomponent
                , children: [
                {
                    path: "logmanage", component: logcomponent, name: "logmanage"
                },
                {
                    path: "servermanage", name: "servermanage", component: {
                    template: "
this is servermanage
"
                }
                },
                {
                    path: "configmanage", name: "configmanage", component: {
                    template: "
this is configmanage
"
                }
                },
                {
                    path: "/", component: logcomponent, name: "logmanage"
                },
    
            ]
            },
            {
                path: "/login", component: logincomponent, name: "login",
                meta: {requiresAuth: true}
            },
    
        ]
    });

这段是我的路由设置

哪位大神能帮我解答下啊?
