HarmonyOS 鸿蒙Next 通过拍照和选择相册方式选择图片后 将图片上传到服务端，具体如下

normal等级的应用不想申请权限也可以通过临时授权的方式使用PhotoViewPicker.select接口得到的uri使用，图片上传到服务端可参考以下示例：

import picker from '[@ohos](/user/ohos).file.picker';

import fs from '[@ohos](/user/ohos).file.fs';

import { common } from '[@kit](/user/kit).AbilityKit';

import request from '[@ohos](/user/ohos).request';

// 使用装饰器定义页面组件

[@Entry](/user/Entry)

[@Component](/user/Component)

struct pothoPage {

 [@State](/user/State) imageList: Array<string> = []

 // 状态变量：原始图片的URI

 [@State](/user/State) imgOriginal: string = '';

 [@State](/user/State) filePath: string = '';

 uploadFileName: string = '';

 // 弹出图片选择器方法

 async openPicker() {

   try {

     // 设置图片选择器选项

     const photoSelectOptions = new picker.PhotoSelectOptions();

     // 限制只能选择一张图片

     photoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE;

     photoSelectOptions.maxSelectNumber = 10;

     // 创建并实例化图片选择器

     const photoViewPicker = new picker.PhotoViewPicker();

     // 选择图片并获取图片URI

     let uris: picker.PhotoSelectResult = await photoViewPicker.select(photoSelectOptions);

     if (!uris || uris.photoUris.length === 0) return;

     console.info('123123uris', JSON.stringify(uris))

     this.imageList = uris.photoUris

     // 获取选中图片的第一张URI

     let uri: string = uris.photoUris[0];

     // 更新状态变量：保存原始图片的URI

     this.imgOriginal = uri;

     // uris.photoUris.forEach(item =>{

     // 打开文件读取流

     let file = fs.openSync(uri, fs.OpenMode.READ_ONLY);

     // 获取当前上下文

     let context = getContext(this) as common.UIAbilityContext;

     // 新建一个保存裁剪后图片的路径

     this.uploadFileName = new Date().getTime() + '.jpg';

     this.filePath = context.cacheDir + '/' + this.uploadFileName;

     // 复制图片到新的路径

     fs.copyFileSync(file.fd, this.filePath);

     // 关闭文件读取流

     fs.closeSync(file);

     console.info('123123filePath', JSON.stringify(this.filePath))

     // })

   } catch (e) {

     console.error('openPicker', JSON.stringify(e));

   }

 }

 //标准记事，资质证明文件，门到站站到门，运输信息（集装箱，整车）

 upPicker() {

   let uploadConfig: request.UploadConfig = {

     url: 'http://xxx/api/gxzx/file/uploadFile',

     header: {

       'Accept': '*/*',

       'Content-Type': 'multipart/form-data',

     },

     method: 'POST',

     files: [

       { filename: 'test', name: 'file', uri: `internal://cache/${this.uploadFileName}`, type: 'jpg' }

     ],

     data: []

   }

   console.log('uploadConfig', JSON.stringify(uploadConfig))

   try {

     request.uploadFile(getContext(), uploadConfig).then((data: request.UploadTask) => {

       console.log('123123', JSON.stringify(data))

       let uploadTask = data

       let upCompleteCallback = (taskStates:Array<request.TaskState>) =>{

         for (let index = 0; index < taskStates.length; index++) {

           console.info('upCompleteCallback',JSON.stringify(taskStates[index]))

         }

       }

       uploadTask.on('complete',upCompleteCallback)

       let upFailCallback = (taskStates:Array<request.TaskState>) =>{

         for (let index = 0; index < taskStates.length; index++) {

           console.info('upFailCallback',JSON.stringify(taskStates[index]))

         }

       }

       uploadTask.on('fail',upFailCallback)

     })

   } catch (err) {

     console.log('987err', JSON.stringify(err))

   }

 }

 // 构建UI界面

 build() {

   Column() {

     // 添加选择图片按钮，点击后调用打开图片选择器方法

     Button('选择图片→').onClick(() => {

       this.openPicker();

     });

     Row() {

       ForEach(this.imageList, (item: string) => {

         Image(item)

           .width('100%')

           .objectFit(ImageFit.Contain);

       })

     }.width('100%')

     Button('上传图片').onClick(() => {

       this.upPicker();

     });

   }

   .width('100%'); // 设置列宽度为100%

 }
