Node.js – v8.deserialize() 方法
该V8。deserialize()方法提供了一种将序列化缓冲区反序列化回原始文本的方法。此方法使用带有默认选项的默认解串器从缓冲区读取原始JS值。
语法
v8.deserialize(buffer)
参数
buffer- 将被反序列化的输入缓冲区。
该函数在对输入缓冲区进行反序列化后返回原始文本输出。
示例1
创建一个文件“deserialize.js”并复制以下代码片段。创建文件后，使用命令“nodedeserialize.js”运行此代码。
//v8.deserialize()演示示例
//导入v8模块
const v8 = require('v8');
//初始化数据变量
var data = "Welcome tonhooo.com!"
//序列化值
var serializedValue = v8.serialize(data);
//打印序列化和反序列化的值
console.log('Serialized data : ', serializedValue)
console.log('Data after de-serializing', v8.deserialize(serializedValue))输出结果C:\home\node>> node deserialize.js Serialized data :Data after de-serializing Welcome tonhooo.com!
示例2
让我们再看一个例子
//v8.deserialize()演示示例
//导入v8模块
const v8 = require('v8');
//初始化数据变量
var data = "Welcome tonhooo.com!"
//序列化值
var serializedValue = v8.serialize(data);
//打印序列化和反序列化的值
console.log('Serialized data : ', serializedValue)
console.log('Data after de-serializing', v8.deserialize(serializedValue))
var number = v8.serialize(12345);
console.log('Serializing numbers', v8.serialize(number))
console.log('Data after de-serializing', v8.deserialize(number))
var decimal = v8.serialize(12345.543);
console.log('Serializing decimal', v8.serialize(decimal))
console.log('Data after de-serializing', v8.deserialize(decimal))输出结果C:\home\node>> node deserialize.js Serialized data :Data after de-serializing Welcome tonhooo.com! Serializing numbers Data after de-serializing 12345 Serializing decimal Data after de-serializing 12345.543
