React Native 将图像保存到特定位置

问题描述

我正在使用 react native cameraroll api 将我的图像保存在存储中.

I am using react native cameraroll api to save my images in storage.

CameraRoll.saveToCameraRoll(data.uri)
            .then(console.log('Success', 'Photo added to camera roll!'))
            .catch(err => console.log('err:', err))

以上代码成功将图像保存在存储中，如 (DCIM/imageName.jpg)

Above code successfully save image in storage like (DCIM/imageName.jpg)

但是我想更改要保存在其他地方的图像的位置，例如 (testfolder/1/imagename.jpg)我试过这样:

But i want to change the location of images to be saved somewhere else like (testfolder/1/imagename.jpg)I tried like this:

CameraRoll.saveToCameraRoll({
            uri: data.uri,
            album: 'test',
        }, 'photo').then((newUri) => {
            console.log('new location of image => ', newUri);
        })

我阅读了这个链接 https://facebook.github.io/react-native/docs/cameraroll.html#savetocameraroll 但没有适当的指南或参数集来更改位置.

I read this link https://facebook.github.io/react-native/docs/cameraroll.html#savetocameraroll but there is no proper guide or parameter set to change location.

有人指导我如何更改保存图像的路径吗?

Anyone guide me how can i change path for saving images?

推荐答案

正如我在这里所说的:如何将图片从 React Native Camera Roll 保存到特定文件夹

在 Android 上，您可以使用 react-native-fetch-blob 及其文件系统访问 API(PictureDir 常量).

On Android, you can use react-native-fetch-blob and its File System Access API (PictureDir constant).

try {
    const data = await this.camera.takePictureAsync()
    await RNFetchBlob.fs.mkdir(`${RNFetchBlob.fs.dirs.PictureDir}/myfolder`)
    await RNFetchBlob.fs.mv(
        data.api,
        `${RNFetchBlob.fs.dirs.PictureDir}/myfolder/${moment().unix()}.jpg`
    )
} catch () {
    ...
}
