uni-app 异步上传图片

因为执行顺序的原因导致部分手机选中图片无法上传，或者上传完成拿不到返回值

async upload(){const [err,{tempFilePaths}] = await uni.chooseImage({count: 9});this.imgList = this.imgList.concat(tempFilePaths);this.uploadTem(tempFilePaths);},async uploadTem(tempFilePaths) {if(!tempFilePaths.length) {return}const item = tempFilePaths.pop();const res= await uni.uploadFile({url: 'https://h5.grasslandfarming.com/api/imgupload', //仅为示例，非真实的接口地址filePath: item,name: 'file',});const [err,{data}] = res;this.uploadImg.push(JSON.parse(data).result);this.uploadTem(tempFilePaths);},//预览previewImage(index){uni.previewImage({urls: this.imgList,current:index,});},
