This article focuses on "how nodejs converts buffer into JSON objects". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how nodejs converts buffer into JSON objects.

Nodejs converts buffer into JSON object: 1, use "Buffer.from ([data list])" statement to create a Buffer object; 2, use "JSON.stringify (Buffer object)" statement for conversion.

This tutorial operating environment: windows7 system, nodejs version 12.19.0, DELL G3 computer.

In Node.js, the Buffer class is a core library released with the Node kernel. The Buffer library provides a way for Node.js to store raw data, allowing Node.js to work with binary data, making it possible to use the Buffer library whenever you need to process data moved during an Ibank O operation in Node.js. The raw data is stored in an instance of the Buffer class. A Buffer is similar to an array of integers, but it corresponds to a piece of raw memory outside the V8 heap memory.

In the official documentation, it is recommended to use the Buffer.from () interface to create Buffer objects.

The function syntax format for converting Node Buffer to JSON objects is as follows:

Buf.toJSON ()

Returns: returns the JSON representation of buf.

When a Buffer instance is serialized, JSON.stringify () implicitly calls the toJSON ().

Example:

Import {Buffer} from 'buffer';const buf = Buffer.from ([0x1, 0x2, 0x3, 0x4, 0x5]); const json = JSON.stringify (buf); console.log (json); / / print: {"type": "Buffer", "data": [1Jing 2Jing 3Jing 4J 5]} so far, I believe you have a better understanding of "how nodejs converts buffer into JSON objects".
