const fs = require('node:fs');
const session = new inspector.Session();
const fd = fs.openSync('profile.heapsnapshot', 'w');
session.connect();
session.on('HeapProfiler.addHeapSnapshotChunk', (m) => {
 fs.writeSync(fd, m.params.chunk);
});
session.post('HeapProfiler.takeHeapSnapshot', null, (err, r) => {
 console.log('HeapProfiler.takeHeapSnapshot done:', err, r);
 session.disconnect();
 fs.closeSync(fd);
}); 拷贝
