Node.js v8 .反序列化()方法
v8 .反序列化()方法是 v8 模块的内置应用编程接口，用于使用默认反序列化程序将缓冲的数据反序列化为 JS 值。
语法:
v8.deserialize( buffer );
参数:该方法接受一个参数，如上所述，如下所述:
- Buffer: This is a required parameter, Buffer/TypedArray/DataView, which refers to the buffered data to be deserialized.
返回值:此方法在反序列化缓冲的数据后返回 JS 值。
下面的例子说明了在 Node.js 中使用 v8.deserialize()方法
示例 1: 文件名:index.js
// Accessing v8 module
const v8 = require('v8');
// Calling v8.deserialize()
console.log(v8.deserialize(v8.serialize("geeksforgeeks")));
使用以下命令运行 index.js 文件:
node index.js
输出:
geeksforgeeks
示例 2: 文件名:
// Accessing v8 module
const v8 = require('v8');
// Calling v8.deserialize()
deserialized_data = v8.deserialize(v8.serialize("abcdefg"));
console.log("\nDeserialized data is ");
console.log(deserialized_data);
deserialized_data = v8.deserialize(v8.serialize(58375693));
console.log("\nDeserialized data is ");
console.log(deserialized_data);
deserialized_data = v8.deserialize(v8.serialize(73847.0234));
console.log("\nDeserialized data is ");
console.log(deserialized_data);
deserialized_data = v8.deserialize(v8.serialize('Geek'));
console.log("\nDeserialized data is ");
console.log(deserialized_data);
使用以下命令运行 index.js 文件:
node index.js
输出:
Deserialized data is
abcdefg
Deserialized data is
58375693
Deserialized data is
73847.0234
Deserialized data is
Geek
