34. onShareAppMessage分享好友和分享微信朋友圈

 onShareAppMessage(OBJECT) 分享 | uni-app官网

此事件需要 return 一个 Object,用于自定义分享内容,其内容如下:

参数名 类型 必填 说明 平台差异说明
title String 分享标题
path String 页面 path ,必须是以 / 开头的完整路径。注意:京东小程序,开头不要加'/' QQ小程序不支持

 index.vue

<script setup>
	import {
		onShareAppMessage
	} from "@dcloudio/uni-app"

	//分享给好友
	onShareAppMessage((e) => {
		return {
			title: "壁纸,好看的手机壁纸",
			path: "/pages/classify/classify"
		}
	})
</script>




wx.onShareTimeline(function listener) 转发 / wx.onShareTimeline

onShareTimeline 监听用户点击右上角转发到朋友圈 微信小程序 2.8.1+
<script setup>
	import {
		onShareAppMessage,
		onShareTimeline
	} from "@dcloudio/uni-app"

	//分享给好友
	onShareAppMessage((e) => {
		return {
			title: "壁纸,好看的手机壁纸",
			path: "/pages/classify/classify"
		}
	})
	//分享朋友圈
	onShareTimeline(() => {
		return {
			title: "壁纸,好看的手机壁纸"
		}
	})

</script>

微信小程序配置了onShareTimeline分享到朋友圈,但是在开发者工具中这里始终是灰色的,在真机调试的时候也没有发现有分享到朋友圈的相关信息。-CSDN博客

 出现的问题待解决

1.下载壁纸,一直loading(已)

2. 分享朋友圈为灰色(已)

解决方法 

3. 请使用“user-select”代替。“<text>”的“selectable”属性已不再使用(未)
