当然在 push 数据之前我们需要实现它的 _read 方法,或者在构造函数的参数中实现 read 方法: constStream=require('stream');constreadableStream =newStream.Readable();RS._read=function(size) {} 或者 constStream=require('stream');constreadableStream =newStream.Readable({read(size) {} }); 经过readableStr...

Node fs.readFile函数的优势在于它是异步的,可以在文件读取的同时执行其他操作,提高了程序的效率和响应速度。 应用场景: 读取配置文件:可以使用fs.readFile函数读取配置文件,获取程序运行所需的配置信息。 读取日志文件:可以使用fs.readFile函数读取日志文件,进行日志分析和处理。
