fs writefile new line not working
提问by anonprophet
i want log my user command
我想记录我的用户命令
function saveLog (nick, command) {
var file = 'log/' + nick + '.log';
var datetime = '[' + getDateTime() + '] ';
var text = datetime + command + '\r\n';
fs.writeFile(file, text, function (err) {
if (err) return console.log(err);
console.log(text);
});
}
the function i made is fine, but it didnt save the log in new line, its just replace text / rewrite the file. whats im missing ?
我做的功能很好，但它没有将日志保存在新行中，它只是替换文本/重写文件。我错过了什么？
thanks
谢谢

fs.writeFilewrites a WHOLE NEW file. What your are looking for is fs.appendFilewhich will make the file if it doesn't exist and append to it. Documentation here.
fs.writeFile写入一个全新的文件。您正在寻找的是fs.appendFile，如果该文件不存在并附加到该文件中，它将生成该文件。文档在这里。
function saveLog (nick, command) {
var file = 'log/' + nick + '.log';
var datetime = '[' + getDateTime() + '] ';
var text = datetime + command + '\r\n';
fs.appendFile(file, text, function (err) {
if (err) return console.log(err);
console.log('successfully appended "' + text + '"');
});
}
