以文本形式查看MongoDB中的BinData

在MongoDB中，字段名为内容的行作为BinData类型， 我想以文本形式查看此字段的内容，MongoDB是否支持mongoshell中的文本。 我的行内容：

有没有办法将内容的值显示为文本？

它已经显示为base64编码文本。你到底在问什么？嗨@CetinBasoz我的意思是我需要它显示为没有编码（解码）的文本。示例：

base64编码文本：4dfs453fdss文本解码：hello

它是二进制数据。如果您询问的是“dXRmLTg=”则是“utf-8”。其他的大多包含不可打印的字符（还有字符（0））。是的，我们能把二进制数据解码成我们能理解的人类文本吗@当然，我是说它们不是人类可读的文本，而是二进制数据。我不知道“内容”是什么意思，因为它被切断了，没有解码来检查。
