uniapp使用uviews上传多张图片

uniapp使用uviews上传多张图片，出现获取的图片路径重复了，是因为放在了onchange中了，解决方法

	<u-upload :auto-upload="true" :action="action" :header="imgheader" :file-list="fileList"
					@on-remove="delimg" max-count="9" @on-choose-complete="upimgchoose" :custom-btn="true" > 
		  <view slot="addBtn" class="slot-btn" hover-class="slot-btn__hover" hover-stay-time="150">
		 		<u-icon name="photo" size="60">u-icon>
		  view>
   u-upload> 

upimgchoose(lists, name) {
		 this.imglist = lists

		 // this.imglist = this.imglist.filter(item => item.url.startsWith('http://tmp/'))
		 //为了添加的时候二次添加图片，获取的路径和第一次添加的路径不同，过滤第二次的路径
	     this.imglist = this.imglist.filter(item => item.url.startsWith('wxfile://tmp'))
		 this.fupimg(this.imglist)
 },

fupimg(lists) {
		 console.log(lists, '选择的')
	 		let that = this
		 uni.request({
			 url: that.configURL.BaseURL + 'XXX',
			 header: {

						//添加的时候修改照片，将之前上传的清空，否则会累积
							that.form.imgs = []
						}
						for await (const item of lists) {
							await uploadPromises.push(await that.uploadImage(datas.host, item.url, datas));

	 })


 },
