//方法1
//Buffer转ArrayBuffer function toArrayBuffer(buf) { var ab = new ArrayBuffer(buf.length); var view = new Uint8Array(ab); for (var i = 0; i < buf.length; ++i) { view[i] = buf[i]; } return ab; } //ArrayBuffer转Buffer function toBuffer(ab) { var buf = new Buffer(ab.byteLength); var view = new Uint8Array(ab); for (var i = 0; i < buf.length; ++i) { buf[i] = view[i]; } return buf; }
//方法2 // Buffer转ArrayBuffer const buf = Buffer.from("this is a test"); console.log(buf); console.log(buf.toString()); var arrayBuf = buf.buffer; //Buffer的buffer属性返回arrayBuf console.log(arrayBuf); //ArrayBuffer转Buffer var arrayBuffer = new ArrayBuffer(16); const buffer = Buffer.from(arrayBuffer); console.log(buffer.buffer === arrayBuffer);
