utf-8 - react native : How to decode base64 encoded string?

我有一个字符串:

除非我解码它，否则我无法理解它。但是，我已经尝试安装 base64 npm 包和 utf8 包，但它提示 _utf2.default.decode is not a function. (In \'_utf2.default.decode(bytes)\', \'_utf2.default.decode\' is undefined) 。

https://github.com/mathiasbynens/utf8.js#utf8decodebytestring

import base64 from 'base-64';
import utf8 from 'utf8';

  const bytes = base64.decode(validationData);
  const text = utf8.decode(bytes); // <----- fails here
  console.log("base64: ", text);

背景:尝试使用以下内容在应用程序购买中实现:https://github.com/chirag04/react-native-in-app-utils 但 receiptData 是 base64 编码的

最佳答案

如果您尝试对其进行解码并将其呈现为图像组件，您可以这样做:

const base64 = 'data:image/png;base64, *put your string here*'

<Image source={{uri: base64}} />
