uniapp开发App实现多图分享给微信好友 (单图也可以)

举例方法：

async manyImgShare() { // 模拟要分享的图片数据
	let list = [
		"https://img.alicdn.com/i3/2207896388619/O1CN01RCu2LC2DXYIOalOyC_!!2207896388619.jpg",
		"https://img.alicdn.com/i4/2207896388619/O1CN01fow0Z32DXYIILfQHI_!!2207896388619.jpg",
		"https://img.alicdn.com/i1/2207896388619/O1CN01D18B4z2DXYIILfM6O_!!2207896388619.jpg",
		"https://img.alicdn.com/i3/2207896388619/O1CN01EL3fje2DXYIEky8z5_!!2207896388619.jpg"
	];
	let urls = {};
	urls.type = 'image'
	urls.pictures = [],
		urls.extra = {
			scene: "WXSceneSession"
		}
	for (let i = 0; i < list.length; i++) {
		// 这里使用 await 改为同步操作 所以该方法前加了async
		// 循环遍历图片路径 使用uni.downloadFile获取到本地临时路径
		let [, imgPath] = await uni.downloadFile({
			url: list[i]
		})
		// 讲本地路径的url 添加到要pictures参数中
		urls.pictures.push(imgPath.tempFilePath)
	}
	console.log(urls) //
	// 这里打印出urls的数据格式 （非file开头的格式)
	/**
		 {
			"type": "image",
			"pictures": ["

			}
		 }
	 */
	// 讲urls传入  调用系统分享 拉起微信 分享给好友
	plus.share.sendWithSystem(urls, function() {
		console.log('分享成功');
	}, function(e) {
		console.log('分享失败：' + JSON.stringify(e));
	})
}
