从脚本中将 python 控制台输出作为电子邮件发送的最佳方法是什么？

Question

我有一个 python 脚本，它可以执行多项操作并在控制台上打印日志。目前，我还没有使用任何日志记录机制（我只是使用print 打印所需的消息）如何获取所有打印件并将其作为电子邮件发送出去？我是否必须将其全部保存在变量中并将其传递给 smtplib？还是有更好的方法？

示例代码

for job in fetch.getJobStats():
        if job['userName']+"_"+job['tenantId'] in summaryTotal:
            summary = summaryTotal[job['userName']+"_"+job['tenantId']]
        else:
            summary = Summary(job['userName'], job['tenantId'])
            summaryTotal[summary.user+"_"+summary.tenant] = summary

        summary.jobs.append(Job(job['jobId'], job['jobStatus'], int(job['fileSize'])))
        totalBw += int(job['fileSize'])

    print("Cumulative Size: " + str(totalBw))
    for summaryKey in summaryTotal.keys():
        summary = summaryTotal[summaryKey]

        inprogress = []
        failed = []
        completed = []
        cancelled = []
        totalBwTenantUser = 0

        for job in summary.jobs:
            totalBwTenantUser += job.filesize
            if job.status == "JOBCANCELLED":
                cancelled.append(job.id)
            elif job.status == "JOBCOMPLETED":
                completed.append(job.id)
            elif job.status == "INPROGRESS":
                completed.append(job.id)
            elif job.status == "JOBFAILED":
                completed.append(job.id)

        print("-" * 50)
        print("Tenant: " + summary.tenant)
        print("User  : " + summary.user)
        print("Size    : " + str(totalBwTenantUser))
        print("\n")
        print("INPROGRESS: " + str(inprogress))
        print("COMPLETED : " + str(completed))
        print("CANCELLED : " + str(cancelled))
        print("FAILED    : " + str(failed))
        print("-" * 50)

Answer 1

你真的应该使用 Python 自带的出色的logging system。

将它与mailinglogger 处理程序结合使用，您将拥有所需的一切：

import logging

from mailinglogger.SummarisingLogger import SummarisingLogger

handler = SummarisingLogger('from@example.com',
                            ('to@example.com',),
                            subject='[LOGS] %s (hostname)s',
                            mailhost='smtp.example.com')

logging.basicConfig(format='%(asctime)s %(message)s',
                    datefmt='%m/%d/%Y %I:%M:%S %p',
                    level=logging.INFO)
logger = logging.getLogger()
logger.addHandler(handler)

logging.info('Sent by email.')

我会使用logging 库，将日志记录配置到一个文件中，然后只需读取该文件的内容并将其发送或将日志文件直接附加到您发送的电子邮件中（请参阅How to send email attachments with Python）。
