encoding 模块就一个方法 convert(),使用方法为:encoding.convert(text, toCharset, fromCharset)。 text: 需要转换的对象,可以为 Buffer 或者 String 对象。 toCharset: 转换后的编码。 fromCharset: 转换前的编码,缺省为 uft8。 转换后的结果为 Buffer 对象。
Should be able to use that for your error message. EDIT: Sorry. I've been typing kMaxStringLength instead of kStringMaxLength. For reference, here's where it's exposed: https://github.com/nodejs/node/blob/v4.1.2/src/node_buffer.cc#L979-L981 Contributor Author mhart commented Oct 6,...
