node.js：mailparser 不工作

Question

我想解析一封电子邮件并找到了 mailparser 包。（使用“npm install mailparser”安装它）。我正在使用 Windows 7。我正在尝试运行这个简单的示例，但没有调用“结束”事件，也没有看到任何日志。这是我运行的：

const MailParser = require("mailparser").MailParser;
const mailparser = new MailParser({debug: true});

let email = "From: 'Sender Name' <sender@example.com>\r\n"+
    "To: 'Receiver Name' <receiver@example.com>\r\n"+
    "Subject: Hello world!\r\n"+
    "\r\n"+
    "How are you today?";

// setup an event listener when the parsing finishes
mailparser.on("end", function(mail_object){
    console.log("From:", mail_object.from); //[{address:'sender@example.com',name:'Sender Name'}]
    console.log("Subject:", mail_object.subject); // Hello world!
    console.log("Text body:", mail_object.text); // How are you today?
});

// send the email source to the parser
mailparser.write(email);
mailparser.end();

我究竟做错了什么？谢谢

根据fine manual，只有两个事件：headers和data。

也许使用simpleParser而不是较低级别（事件驱动）最简单MailParser：

const simpleParser = require('mailparser').simpleParser;
...
simpleParser(email).then(function(mail_object) {
  console.log("From:", mail_object.from.value);
  console.log("Subject:", mail_object.subject);
  console.log("Text body:", mail_object.text);
}).catch(function(err) {
  console.log('An error occurred:', err.message);
});
