google gmails/email 地址的数据调节

Question

我正在尝试为 gmail 创建过滤器，我需要获取发送到的电子邮件。问题是电子邮件收件人行中的电子邮件可以有多种不同的格式。我想看看是否有比我正在做的更简单的方法来统一电子邮件的格式。我只是要说明我能找到并处理的每一个案例。

function getTo(email) { 
// Logs the To lines of up to the first 1-500 emails in your Inbox 
var threads = GmailApp.getInboxThreads(0, 75);
for (var i = 0; i < threads.length; i++) {
    var messages = threads[i].getMessages();
    for (var j = 0; j < messages.length; j++) {
        var emailto = messages[j].getTo();
        //runs the .to emails through the data conditioning function
        //emailprocess(email,emailto)
        }
        Logger.log(emailto);
    }
}



function main () {
var email = Session.getActiveUser().getEmail();
Logger.log(email);
getTo(email)
// createToFilte(toAddress, labelName)
}


function emailprocess(email,emailto){
var emailto = emailto.toLowerCase();
        switch (emailto) {
            case email:
                label = 0;
                break;
            case "john doe <johndoe@gmail.com>":
                label = 0;
                break;
            case "<johndoe@gmail.com>":
                label = 0 ;
                break;
            default:
                label = emailto.replace('johndoe+', '');
                label = label.replace("@gmail.com","")
                break;
        }
}

电子邮件可以采用多种不同的格式，这里有一些：

john doe < johndoe@gmail.com >
johndoe@gmail.com
johndoe@gmail.com, janedoe@gmail.com
johndoe+65@gmail.com

而且可能只多一点。任何帮助都会很棒。我也是最好的程序员，所以任何使它更精简的方法都会很棒。

解决方案：

function getTo(email) {
var emailregex = /([a-zA-Z0-9_\.\+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-\.]+)/gm  
var threads = GmailApp.getInboxThreads(0, 500); // Logs the To lines of up   to the first 1-500 emails in your Inbox 
for (var i = 0; i < threads.length; i++) {
    var messages = threads[i].getMessages();
    for (var j = 0; j < messages.length; j++) {
        var emailto = messages[j].getTo()
        var emailto = emailto.toLowerCase();
        //Logger.log(emailto);
        emailto = emailto.match(emailregex); //runs the .to emails through    the data conditioning
      Logger.log(emailto);
      if(emailto != null){
        for (var k = 0; k < emailto.length; k++) {
            if (emailto[k].indexOf("+") > -1) {
                var labelto = emailto[k].slice(emailto[k].indexOf("+") + 1,       emailto[k].indexOf("@"));
                createToFilter(emailto[k], labelto)
                Logger.log(emailto[k]);
                Logger.log(labelto);
            }

        }
      }


    }

}
}

您可以尝试使用电子邮件正则表达式（那里有很多），这是一个示例：

function getTo(email) { 
var emailregex =  /([a-zA-Z0-9_\.\+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-\.]+)/gm
// Logs the To lines of up to the first 1-500 emails in your Inbox 
var threads = GmailApp.getInboxThreads(0, 75);
for (var i = 0; i < threads.length; i++) {
    var messages = threads[i].getMessages();
    for (var j = 0; j < messages.length; j++) {
        var emailto = messages[j].getTo().match(emailregex);
        //runs the .to emails through the data conditioning function
        //emailprocess(email,emailto)
        }
        Logger.log(emailto);
    }
}
