如何缩小JavaScript缓冲区

Question

我知道你不能直接修剪它，但这是正确的方法吗：将缓冲区转换为字符串，然后修剪，然后转换为缓冲区？我使用的是Node.js v.6.12.x

var buf = Buffer.alloc(xxxxxx);
.....
// buffer gets its value
.....
let buffParsed = String.fromCharCode.apply(null, buf);
buffParsed = buffParsed.replace(/\"/g, '"');
console.log(buffParsed.length);
//now convert back to buffer... How?
//sorry for dummy question

Answer 1

使用的Buffer.from

var buf = Buffer.alloc(xxxxxx);
.....
// buffer gets its value
.....
let buffParsed = Buffer.from(String.fromCharCode(...buf).replace(/\"/g, '"'));
