react-native:共享api将base64字符串而不是图像传递给WhatsApp

时间:2018-10-25 20:09:02

标签: javascript reactjs react-native

嘿,我正在努力通过WhatsApp共享base64图像。在iOS和Android中,实际的base 64也被共享,而不是图像。

如果我使用iMessage或电子邮件(iOS),base64图像将被转换并按预期显示。在Android中,使用电子邮件进行共享仅显示base64字符串。还有其他人面临同样的问题吗?

我正在使用本机〜0.55.2

我不确定它如何与react-native添加的内置Share功能一起使用。但是使用react-native-share对我有用。

我找到了解决此问题的方法。当前,我还在我的一个应用程序中使用它。您可以在按下按钮时直接插入并播放以下onClick功能。

RNFS.downloadFile ,使用URL下载远程映像并将其保存到路径。 RNFS.readFile ,将本地保存的文件数据转换为Whatsapp和其他应用程序直接支持的base64。

import Share from 'react-native-share';
import RNFS from 'react-native-fs';

async onClick(url, id){
        const path = `${RNFS.DocumentDirectoryPath}/${id}.jpg`;
        await RNFS.downloadFile({ fromUrl: url, toFile: `file://${path}` }).promise
            .then((res) => {
                return res;
            })
            .catch((err) => {
                return err;
            });
        RNFS.readFile(`file://${path}`, 'base64').then((res) => {
            let shareOptionsUrl = {
                title: 'My Application',
                message: 'Use my application',
                url: `data:image/jpeg;base64,${res}`, // use image/jpeg instead of image/jpg
                subject: 'Share information from your application'
            };
            Share.open(shareOptionsUrl);
        })
    }

URL 是图像的远程URL, id 是该图像的一些唯一标识符。
