需求：自己留个记录

<div class="button—2" @click="uploadFile"><input type="file" ref="file" multiple="multiple" @change="fileChange" style="display:none">上传</div>

async uploadFile() {this.$refs.file.dispatchEvent(new MouseEvent("click"));
},
async fileChange(event) {const file = event.target.files[0];const result = await fileUploadToFolder({folder: this.currentId,file: file});if (result) {this.$refs.file.value = "";event.target.value = 0;}
}
