请参考以下示例修改，检查下let fileInfo: filePreview.PreviewInfo是否正确， demo： import { filePreview } from '[@kit](/user/kit).PreviewKit'; import { BusinessError } from '[@kit](/user/kit).BasicServicesKit'; import fs from '[@ohos](/user/ohos).file.fs'; import fileUri from "[@ohos](/user/ohos).file.fileuri"; let uiContext = getContext(this); let displayInfo: filePreview.DisplayInfo = { x: 100, y: 100, width: 800, height: 800 }; let fileInfo: filePreview.PreviewInfo = { title: 'th.jpg', uri: 'file://com.example.previewfileapp/data/storage/el2/base/haps/entry/files/th.jpg', mimeType: 'image/jpeg' }; [@Entry](/user/Entry) [@Component](/user/Component) struct Index { build() { Column() { Row() { Button('复制') .onClick(() => { try { getContext(this).resourceManager.getRawFileContent("th.jpg", (error: BusinessError, value: Uint8Array) => { if (error != null) { console.error("error is " + error); } else { let myBuffer:ArrayBufferLike = value.buffer let context = getContext(this); //沙箱路径 let filePath = context.filesDir + '/' + "th.jpg"; console.log("testTag-filePath:" + filePath); let file = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE); let writeLen = fs.writeSync(file.fd, myBuffer); console.info("testTag-write data to file succeed and size is:" + writeLen); fs.closeSync(file); } }); } catch (error) { let code = (error as BusinessError).code; let message = (error as BusinessError).message; console.error(`callback getRawFileContent failed, error code: ${code}, message: ${message}.`); } }) } .justifyContent(FlexAlign.SpaceAround) .width('100%') Row() { Button('预览') .onClick(() => { filePreview.openPreview(uiContext, fileInfo, displayInfo).then(() => { console.info('Succeeded in opening preview'); }).catch((err: BusinessError) => { console.error(`Failed to open preview, err.code = ${err.code}, err.message = ${err.message}`); }); }) } .justifyContent(FlexAlign.SpaceAround) .width('100%') } .justifyContent(FlexAlign.SpaceAround) .height('100%') .width('100%') } }
