2023-06-05 12:24:05 580

参数

它需要一个参数-

length-此参数接受传递给的缓冲区长度的输入。serializer.writeRawBytes()

示例1

创建一个名为“readRawBytes.js”的文件并复制以下代码片段。创建文件后，使用命令“nodereadRawBytes.js”运行此代码。

//v8.serializer.readRawBytes()演示示例

//导入v8模块
const v8 = require('v8');

//初始化序列化器对象
const serializer = new v8.Serializer();

//将数据写入内部缓冲区
serializer.writeRawBytes(v8.serialize(12345));

//初始化序列化器对象
const deserializer = new
v8.Deserializer(serializer.releaseBuffer());

//从内部缓冲区读取原始字节数据
console.log(deserializer.readRawBytes(6));

输出结果

C:\home\node>> node readRawBytes.js

示例2

让我们再看一个例子

//v8.serializer.readRawBytes()演示示例

//导入v8模块
const v8 = require('v8');

//初始化序列化器对象
const serializer = new v8.Serializer();
var buffer;

//将数据写入内部缓冲区
function writeRawBytes(data, len) {
   serializer.writeRawBytes(v8.serialize(data));
   buffer = serializer.releaseBuffer();
   console.log("Data written & Retrieved :")
   console.log(buffer)
   readRawBytes(len);
}

//从内部缓冲区读取原始字节数据
function readRawBytes(len) {
   const deserializer = new v8.Deserializer(buffer);
   console.log(deserializer.readRawBytes(len));
}

writeRawBytes(9876, 6)
writeRawBytes('Welcome to nhooo', 29)
writeRawBytes(12345, 6)

输出结果

C:\home\node>> node readRawBytes.js
Data written & Retrieved :
   
   
Data written & Retrieved :
