据我所知，你无法访问整个身体(使用mail和html标签)。您具有XPCOM可编写脚本接口nsIMsgDbHdr的功能和属性。

我有一个发送邮件的附加组件。我在以下代码片段的帮助下阅读了整个邮件正文。如您所见，我从磁盘读取整个邮件并将其内容加载到变量中。您也可以使用它来阅读完整的邮件正文。

function SendMailNow(aMsgDBHdr) {

var aMsgURI = aMsgDBHdr.folder.getUriForMsg(aMsgDBHdr);

var msgWindow = Components.classes["@mozilla.org/messenger/msgwindow;1"]

.createInstance();

msgWindow = msgWindow.QueryInterface(Components.interfaces.nsIMsgWindow);

var msgStream = Components.classes["@mozilla.org/network/sync-stream-listener;1"]

.createInstance();

msgStream = msgStream.QueryInterface(Components.interfaces.nsIInputStream);

var aMsgService = messenger.messageServiceFromURI(aMsgURI);

var scriptInputStream = Components.classes["@mozilla.org/scriptableinputstream;1"]

.createInstance();

scriptInputStream = scriptInputStream

.QueryInterface(Components.interfaces.nsIScriptableInputStream);

scriptInputStream.init(msgStream);

try {

aMsgService.streamMessage(aMsgURI, // uri of message to stream

msgStream, // a stream listener listening to the message

msgWindow, // a nsIMsgWindow for progress and status feedback

null, // a nsIUrlListener that is notified when url starts and stops

false, // it will create a stream converter from message rfc2822 to

null // Header added to the URI. e.g., header=filter

);

} catch (ex) {

}

// Creating content

var content = "";

while (scriptInputStream.available()) {

content = content + scriptInputStream.read(512);

if (content.match(/\r\n\r\n/) || content.match(/\n\n/)) {

if (sendMail(content, aMsgDBHdr.messageId)) {

log("SEND_DONE\t" + aMsgDBHdr.messageId + "\t"

+ aMsgDBHdr.subject);

} else {

log("SEND_FAILED\t" + aMsgDBHdr.messageId + "\t"

+ aMsgDBHdr.subject);

}

}

}

}

我希望这会对你有所帮助！
