HarmonyOS 鸿蒙Next request.uploadFile是否只能上传cache目录下的文件？

上传只能上传cache目录下的文件，如果你需要上传相册，需要利用fs文件的能力，把相册图片拷贝到cache目录下 fs参考： https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-file-fs-V5#fscopyfilesync

上传应用参考： https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/app-file-upload-download-V5#%E4%B8%8A%E4%BC%A0%E5%BA%94%E7%94%A8%E6%96%87%E4%BB%B6

例如：上传文件地址internal://cache/xx.jpg，这里对应的是沙箱目录haps/entry/cache下的xx.jpg

下面是一个将文件存到cache目录下的demo:

import { BusinessError } from '@kit.BasicServicesKit';
import fs from '@ohos.file.fs';
import picker from '@ohos.file.picker';
import { common } from '@kit.AbilityKit';
@Entry
@Component
struct Index {
@State message: string = ‘Hello World’;
async photoPick() {
try {
let context = getContext(this) as common.Context;
let pathDir = getContext().cacheDir;
let PhotoSelectOptions = new picker.PhotoSelectOptions();
PhotoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE;
PhotoSelectOptions.maxSelectNumber = 5;
let photoPicker = new picker.PhotoViewPicker();
photoPicker.select(PhotoSelectOptions)
.then(async (PhotoSelectResult: picker.PhotoSelectResult) => {
console.info('PhotoViewPicker.select successfully, PhotoSelectResult uri: ’ + JSON.stringify(PhotoSelectResult));
let file1 = fs.openSync(PhotoSelectResult.photoUris[0])
fs.copyFileSync(file1.fd, pathDir+/${file1.name})
console.log(“pathDir”+pathDir)
let file2 = fs.openSync(pathDir+/${file1.name}, fs.OpenMode.READ_WRITE)
console.log(file fd ==> ${file2.fd} | file path ==> ${file2.path})
// fs.closeSync(file1)
// fs.closeSync(file2)
}).catch((err: BusinessError) => {
console.error('PhotoViewPicker.select failed with err: ’ + JSON.stringify(err));
});
} catch (error) {
let err: BusinessError = error as BusinessError;
console.error('PhotoViewPicker failed with err: ’ + JSON.stringify(err));
}
}
