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。
用法:
zlib.createBrotliCompress( options )
参数:此方法接受单个参数选项,这是一个包含zlib选项的可选参数。
返回值:它返回一个新的BrotliCompress对象。
以下示例说明了Node.js中zlib.createBrotliCompress()方法的使用:
范例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!
范例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 at WriteStream.Writable.pipe (_stream_writable.js:243:24) at /home/runner/CorruptFlawedSoftwaresuite/index.js:19:15 at Script.runInContext (vm.js:133:20) at Object. (/run_dir/interp.js:156:20) at Module._compile (internal/modules/cjs/loader.js:778:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10) at Module.load (internal/modules/cjs/loader.js:653:32) at tryModuleLoad (internal/modules/cjs/loader.js:593:12) at Function.Module._load (internal/modules/cjs/loader.js:585:3)
在此,配管未按正确的顺序进行,因此会引发错误。
