无法解码java中的base64字符串

Question

我正在尝试解码base64字符串。但不知何故，它不是解码完整的字符串。下面是base64字符串。

... 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 == gMCwwXkdCIDc3OCwgMTE5NiwgMkJeRlMgDQpeTEgwDQpeWFoNCg

我可以解码这个base64字符串https://www.base64decode.org/并正确解码它。但是当我尝试使用代码对它进行解码时，它就会介入。（我不确定bur是因为某些特殊字符。）下面是我用来解码的代码。

StringUtils.newStringIso8859_1(Base64.decodeBase64(labelResponse.getLabelUrl().getBytes()))

我不知道出了什么问题。

我期待的输出。

Answer 1

系统上的默认字符集应该有问题。试试这个，

StringUtils.newStringIso8859_1(Base64.decodeBase64(str.getBytes(StandardCharsets.UTF_8)))

您的JVM默认字符集应该不是UTF-8。在上面的代码中，UTF-8 Charset被传递

Answer 2

您可以指定如何获取图像？如果它来自您控制的服务器，或来自返回图像的工件，则必须确保base64图像字符串中没有特殊字符。你可以使用例如Javascript函数encodeURIComponent（）来做到这一点。如果您正在使用Java，可以查看此链接以查看其等效的Java equivalent to JavaScript's encodeURIComponent that produces identical output?
