    2.登录功能前端实现

    2.1在HBuilderX中创建uni-app类型的项目,选择默认模板即可然后建目录结构,如图所示:

    • commons目录放置一些全局配置函数
    • components目录放置封装的组件
    • pages目录放置页面文件
    • static目录放置图片资源
    • style目录放置全局样式文件

    2.2 pages目录的各个子目录里分别放相应的vue文件

    2.3 tab图片

    2.4配置pages.json文件如下:

    {
        "pages": [
            //pages数组中第一项表示应用启动页,参考:https://uniapp.dcloud.io/collocation/pages
            {
                "path": "pages/index/index",
                "style": {
                    "navigationBarTitleText": "文章",
                    //允许下拉刷新
                    "enablePullDownRefresh": true
                }
            },
            {
                "path": "pages/message/message",
                "style": {
                    "navigationBarTitleText": "消息"
                }
            },
            {
                "path": "pages/my/my",
                "style": {
                    "navigationBarTitleText": "我的"
                }
            },
            {
                "path": "pages/signin/signin",
                "style": {}
            },
            {
                "path": "pages/write/write",
                "style": {}
            },
            {
                "path": "pages/info/info",
                "style": {}
            },
            {
                "path": "pages/setting/setting",
                "style": {}
            }
        ],
        "globalStyle": {
            "navigationBarTextStyle": "black",
            // "navigationBarTitleText" : "简阅",
            "navigationBarBackgroundColor": "#F8F8F8",
            "backgroundColor": "#F8F8F8"
        },
        "tabBar": {
            "color": "#707070",
            "selectedColor": "#DE533A",
            "list": [{
                    "pagePath": "pages/index/index",
                    "text": "文章",
                    "iconPath": "static/nav1.png",
                    "selectedIconPath": "static/nav1-a.png"
                },
                {
                    "pagePath": "pages/message/message",
                    "text": "消息",
                    "iconPath": "static/nav2.png",
                    "selectedIconPath": "static/nav2-a.png"
                },
                {
                    "pagePath": "pages/my/my",
                    "text": "我的",
                    "iconPath": "static/nav3.png",
                    "selectedIconPath": "static/nav3-a.png"
                }
            ]
        }
    }
    

    2.5style目录新建style.css全局样式表

    * {
        font-size: 14pt;
    }
    
    .container {
        width: 95%;
        margin: 0 auto;
    }
    
    .avatar {
        width: 60px;
        height: 60px;
        border-radius: 50%;
    }
    
    .list {
        display: flex;
        flex-direction: column;
    }
    
    .list-item {
        width: 100%;
        height: 50px;
        background-color: #fff;
        border-bottom: 1px solid #eee;
        display: flex;
        align-items: center;
    }
    .green-btn {
        background-color: rgb(26, 173, 25);
        color: #fff;
    }
    

    2.6App.vue文件中引入全局样式表

    <style>
     @import 'style/style.css';
    </style>
    
    

    2.7 my.vue

    <template>
        <view class="container">
