.net 我们如何记录与SmtpClient的SMTP对话?
例如,为了进行故障排除,我需要查看SMTP消息来回的内容: OUT : EHLO machinename IN : 250-ReallyCoolEmailServer Hello [10.24.41.72] IN : 250-SIZE IN : 250-PIPELINING IN : (...and so on...) OUT : MAIL FROM: <some.address@example.com> IN : 250 <some.address@example.com>... Sender ok 输出:EHLO machinename IN:250 ReallyCoolEmailServer Hello[10.24.41.72] 英寸:250码 IN:250-流水线 在:(…等等…) 发出:邮寄地址: 在:250。。。发送方ok ……等等 我在中找不到任何登录选项。这里我能找到的关于.net 我们如何记录与SmtpClient的SMTP对话?,.net,smtpclient,.net,Smtpclient,例如,为了进行故障排除,我需要查看SMTP消息来回的内容: OUT : EHLO machinename IN : 250-ReallyCoolEmailServer Hello [10.24.41.72] IN : 250-SIZE IN : 250-PIPELINING IN : (...and so on...)

SmtpClient
的唯一问题就是不要谈论看到实际的对话,或者谈论使用第三方工具,如WireShark
这似乎是一个相当大的遗漏,所以我猜我只是遗漏了一些基本的东西。:-) 就我自己而言,我实际上更喜欢像Wireshark这样“无偏见”的外部工具,以查看实际发生的情况
SmtpClient
确实有跟踪功能——它将输出发送到System.Net
跟踪功能——但这不包括实际通过线路传输的数据。当然,您可以使用System.Net.Sockets
跟踪,通过如下方式配置您的应用程序来获得:
<system.diagnostics>
<sources>
<source name="System.Net">
<listeners>
<add name="TraceFile"/>
</listeners>
</source>
<source name="System.Net.Sockets">
<listeners>
<add name="TraceFile"/>
</listeners>
</source>
</sources>
<sharedListeners>
<add
name="TraceFile"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="trace.log"
/>
</sharedListeners>
<switches>
<add name="System.Net" value="Verbose"/>
<add name="System.Net.Sockets" value="Verbose"/>
</switches>
<trace autoflush="true" />
</system.diagnostics>

最后,不,你没有遗漏任何东西--SmtpClient
没有协议级别的跟踪,这确实是一个很大的遗漏
