node.js Buffer.toString() 支持哪些编码？

What encodings does Buffer.toString() support?

提问by Grayda

I'm writing an app in node.js, and see that I can do things like this:

我正在 node.js 中编写一个应用程序，并看到我可以做这样的事情：

var buf = new Buffer("Hello World!")
console.log(buf.toString("hex"))
console.log(buf.toString("utf8"))

And I know of 'ascii' as an encoding type (it'll take an ASCII code, such as 112and turn it into a p), but what other types of encoding can I do?

而且我知道“ascii”是一种编码类型（它将采用 ASCII 代码，例如112并将其转换为 a p），但是我可以做哪些其他类型的编码？

The official node.js documentation for Bufferis the best place to check for something like this. As previously noted, Buffercurrently supports these encodings: ascii, utf8, utf16le/ucs2, base64, binary, and hex.

官方node.js 文档Buffer是检查此类内容的最佳位置。如前所述，Buffer目前支持这些编码：ascii，utf8，utf16le/ ucs2，base64，binary，和hex。

http://www.w3resource.com/node.js/nodejs-buffer.php有答案。您可以在.toString()缓冲区中使用以下类型：

• ascii
• utf8
• utf16le
• ucs2(alias of utf16le)
• base64
• binary
• hex

• ascii
• utf8
• utf16le
• ucs2（的别名utf16le）
• base64
• binary
• hex
