运行时,以下代码在独立项目中运行。但是,如果我想用终端中的输出而不是代码中已经存在的数组替换变量“ sample_text”,我将如何修改代码?例如,在另一个文件中运行节点时,说输出看起来像“学生:丹尼,年龄:28,体重:148”。
// writefile.js
const fs = require('fs');
let sample_text = 'student: danny, age: 28, weight: 148'
// write to a new file named sample.json
fs.writeFile('sample.json', sample_text, (err) => {
if (err) throw err;
console.log('Text saved!');
});

类似这样的东西:
const readline = require('readline');
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question('Enter data', (data) => {
fs.writeFile('2pac.txt', data, (err) => {
if (err) throw err;
console.log('Text saved!');
});
rl.close();
});

您需要做两件事:
您的节点程序应如下所示:
null
然后您应该通过从终端运行以下命令来启动selenium和该节点程序:
private static string CreateSpecialFormattedDateXml(DateTime? theDate)
{
StringBuilder sb = new StringBuilder();
if (theDate != null)
{
sb.Append(CreateFieldNodeXml("year", theDate.Year.ToString()));
sb.Append(CreateFieldNodeXml("month", theDate.Month.ToString()));
sb.Append(CreateFieldNodeXml("day", theDate.Day.ToString()));
}
return sb.ToString();
}
private static string CreateFieldNodeXml(string fieldname, string fieldValue)
{
if (!string.IsNullOrEmpty(fieldValue))
{
return "<" + fieldname + ">" + fieldValue + "</" + fieldname + ">";
}
return null;
}
