如何通过 link 将视频直接分享到 facebook/instagram 作为可以使用 react-native 直接播放的视频

Question

如何使用 react-native 通过 link 将视频直接分享到 Facebook/Instagram/twitter。我正在使用 react-native-share 在 Instagram/Facebook 上分享视频，但它正在作为 link 分享，但我想像 TikTok 一样将它们作为视频分享。

我怎样才能做到这一点？我知道它可以通过将它转换为 base 64，所以是否有任何库可以直接将 links 转换为 base 64？否则我需要先下载它然后检索它然后转换为 base 64 然后共享它。

请帮忙！

如果有人需要完整的代码，将回答我是如何做到的：

shareURL = async (socialMedia) => {
        let facebook = socialMedia === 'facebook'
        let twitter = socialMedia === 'twitter'
        const { video, uploadingStatus } = this.state;

        this.setState({ isSliderModalVisible: true }, async () => {
            let uploadOptions = { fileCache: true, appendExt: 'mp4', timeout: 60000, indicator: true, IOSBackgroundTask: true, }
            const res = await RNFetchBlob.config(uploadOptions).fetch('GET', video, {})
                .progress((received, total) => {
                    this.setState({ uploadingStatus: (received / total) * 100 })
                    console.log('Progress', (received / total) * 100);
                })
            const filePath = res.path(); //to delete video
            const base64String = await res.base64();
            const url = `data:video/mp4;base64,${base64String}`;
            await RNFetchBlob.fs.unlink(filePath); //deleted the video from path of celebfie.
            this.setState({ isSliderModalVisible: false })
            setTimeout(() => {
                const shareOptions = {
                    title: 'Celebfie',
                    message: hashtags,
                    subject: 'Sharing my intro video which I recorded in Celebfie.',
                    url: url,
                    type: 'video/mp4',
                    social: facebook ? Share.Social.FACEBOOK : twitter ? Share.Social.TWITTER : Share.Social.INSTAGRAM
                };
                Share.shareSingle(shareOptions).then((res) => this.setState({ sharedVideoToSocialNetwork: true }))
                    .catch((err) => { Global.customToast('Video sharing failed.', 'failure') })
            })
        }, 1000);
    }

Answer 1

你可以这样做：

Share.open(
      {
        message: `I have successfully Completed this course`,
        title: 'Share',
        url: 'file:///documents..',
        type: 'video/mp4',
      },
      {
        // Android only:
        dialogTitle: 'Share',
        // iOS only:
        excludedActivityTypes: ['com.apple.UIKit.activity.PostToTwitter'],
      },
    );

在这里回答我自己的问题，它是如何工作的：

shareURL = async (socialMedia) => {
        let facebook = socialMedia === 'facebook'
        let twitter = socialMedia === 'twitter'
        const { video, uploadingStatus } = this.state;

        this.setState({ isSliderModalVisible: true }, async () => {
            let uploadOptions = { fileCache: true, appendExt: 'mp4', timeout: 60000, indicator: true, IOSBackgroundTask: true, }
            const res = await RNFetchBlob.config(uploadOptions).fetch('GET', video, {})
                .progress((received, total) => {
                    this.setState({ uploadingStatus: (received / total) * 100 })
                    console.log('Progress', (received / total) * 100);
                })
            const filePath = res.path(); //to delete video
            const base64String = await res.base64();
            const url = `data:video/mp4;base64,${base64String}`;
            await RNFetchBlob.fs.unlink(filePath); //deleted the video from path of Sexy lady.
            this.setState({ isSliderModalVisible: false })
            setTimeout(() => {
                const shareOptions = {
                    title: 'Sexy Lady',
                    message: hashtags,
                    subject: 'Sharing my intro video which I recorded in Celebfie.',
                    url: url,
                    type: 'video/mp4',
                    social: facebook ? Share.Social.FACEBOOK : twitter ? Share.Social.TWITTER : Share.Social.INSTAGRAM
                };
                Share.shareSingle(shareOptions).then((res) => this.setState({ sharedVideoToSocialNetwork: true }))
                    .catch((err) => { Global.customToast('Video sharing failed.', 'failure') })
            })
        }, 1000);
    }
