Node.js zlib.createBrotliCompress() 方法
zlib.createBrotliCompress() 方法是 Zlib 模块的内置应用程序编程接口,用于创建 BrotliCompress 对象。
句法:
zlib.createBrotliCompress( options )
参数:此方法接受单个参数选项,该选项是包含 zlib 选项的可选参数。
返回值:它返回一个新的 BrotliCompress 对象。
下面的例子说明了在 Node.js 中zlib.createBrotliCompress() 方法的使用:
示例 1:
// Node.js program to demonstrate the
// createBrotliCompress() method
// Including zlib and fs module
const zlib = require("zlib");
const fs = require('fs');
// Creating readable Stream
const inp = fs.createReadStream('input.txt');
// Creating writable stream
const out = fs.createWriteStream('input.txt.gz');
// Calling createBrotliCompress method
const brot = zlib.createBrotliCompress();
// Piping
inp.pipe(brot).pipe(out);
console.log("Program Completed!");
输出:
Program Completed!
示例 2:
// Node.js program to demonstrate the
// createBrotliCompress() method
// Including zlib and fs module
const zlib = require("zlib");
const fs = require('fs');
// Creating readable Stream
const inp = fs.createReadStream('input.txt');
// Creating writable stream
const out = fs.createWriteStream('input.txt.gz');
// Calling createBrotliCompress method
const brot = zlib.createBrotliCompress();
// Piping
inp.pipe(out).pipe(brot);
console.log("Program Completed!");
输出:
Error [ERR_STREAM_CANNOT_PIPE]: Cannot pipe, not readable

在这里,管道没有按正确的顺序完成,因此会引发错误。
