示例代码：

package.json

{  
    "private": true,  
    "uni-app": {  
        "scripts": {  
            "h5-mobile": {  
                "title": "手机移动端 H5 站点",  
                "BROWSER": "Chrome",  
                "env": {  
                    "UNI_PLATFORM": "h5"  
                },  
                "define": {  
                    "H5-MOBILE": true  
                }  
            },  
            "h5-weixin": {  
                "title": "微信服务号 H5 站点",  
                "BROWSER": "Chrome",  
                "env": {  
                    "UNI_PLATFORM": "h5"  
                },  
                "define": {  
                    "H5-WEIXIN": true  
                }  
            }  
        }  
    }  
}

操作步骤：

<template>  
    <view class="content">  
        <image class="logo" src="/static/logo.png"></image>  
        <view class="text-area">  
            <text class="title">{{title}}</text>  
        </view>  
    </view>  
</template>  

<script>  
    export default {  
        data() {  
            return {  
                title: 'Hello'  
            }  
        },  
        onLoad() {  
            // #ifdef H5-WEIXIN  
            console.log('H5-WEIXIN 微信服务号运行');  
            // #endif  
        },  
        methods: {  

        }  
    }  
</script>  

<style>  
    .content {  
        display: flex;  
        flex-direction: column;  
        align-items: center;  
        justify-content: center;  
    }  

    .logo {  
        height: 200rpx;  
        width: 200rpx;  
        margin-top: 200rpx;  
        margin-left: auto;  
        margin-right: auto;  
        margin-bottom: 50rpx;  
    }  

    .text-area {  
        display: flex;  
        justify-content: center;  
    }  

    .title {  
        font-size: 36rpx;  
        color: #8f8f94;  
    }  
</style>

预期结果：
