[Unhandled promise rejection: Error: Location "imageURL" isn't readable - Expo React Native

Question

我正在尝试使用 expo FileSystem 将 firebase 图像 URL 转换为 base64，但出现以下错误。

[Unhandled promise rejection: Error: Location "https://pngimg.com/uploads/birds/small/birds_PNG108.png" isn't readable - Expo React Native

URL 非常完美，因为我可以在浏览器中打开它。我正在尝试关注 URL，并尝试了多个其他 URL。

https://pngimg.com/uploads/birds/small/birds_PNG108.png

以下是我的代码。

import * as FileSystem from 'expo-file-system';
<TouchableOpacity onPress={async () => {
      const base64 = await FileSystem.readAsStringAsync('https://pngimg.com/uploads/birds/small/birds_PNG108.png', { encoding: 'base64' });
        Share.share(
          {
            title: 'test title',
            url: item.url,
          },
          {
            excludedActivityTypes: [
              
            ],
          }
        );
     }}>
    </TouchableOpacity>
    
  )}

在任何论坛上都找不到解决此问题的方法。

也许你更应该使用

import * as Sharing from 'expo-sharing';

将图像临时保存在光盘上并使用 uri 共享图像。

比

import { Share} from 'react-native';
