console.error()写入stderr流,而console.log()写入stdout流。你可以使用process.stderr和process.stdout访问这些流。这对于将错误信息和信息重定向到不同的文件非常有用,就像我们在下面的代码示例中所做的那样。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 constfs=require('fs');consterrorFs=fs.createW...

将数据写入文件是通过fs.writeFile()实现的: 'use strict'; var fs = require('fs'); var data = 'Hello, Node.js'; fs.writeFile('output.txt', data, function (err) { if (err) { console.log(err); } else { console.log('ok.'); ...
process.stdout.write = infoFs.write.bind(infoFs); console.error('This is an error message.'); console.log('This is a log message.'); 运行此代码时,传递给 error() 和 log() 的消息将输出到相应的文件,而不是控制台。 5.warn()
[2] Liblouis writes messages to stdout and stderr by default. Emscripten redirects these toModule.printandModule.printErr, which are implemented as:function print(x) { console.log(x); }andfunction printErr(x) { console.warn(x); }. There is no need to overwrite these functions. You can ...

sendToWormhole(readStream, true); Writable Stream readableStream.on('data', function(chunk) { writableStream.write(chunk); }); writableStream.end(); 当end()被调用时,所有数据会被写入,然后流会触发一个finish事件。注意在调用end()之后,你就不能再往可写流中写入数据了。
