在Thunderbird扩展中收到邮件发件人 [英] Getting mail sender in a Thunderbird extension

问题描述

我正在开发一个非常简单的Thunderbird扩展，它应该在发送邮件时提醒发件人的姓名以及收件人的姓名。问题是gMsgCompose.compFields.from字段在下面的代码段中是空的（.to字段按预期工作），它处理compose-send-message事件。我在这里缺少什么？

  function send_event_handler（evt）{
 var msgcomposeWindow = document.getElementById（msgcomposeWindow ）; 
 var msg_type = msgcomposeWindow.getAttribute（msgtype）; 
 
 //不要继续，除非这是一个实际的发送事件
 if（！（msg_type == nsIMsgCompDeliverMode.Now || msg_type == nsIMsgCompDeliverMode.Later））
 return; 
 
 var promptService = Components.classes [@ mozilla.org/embedcomp/prompt-service;1\"].getService(Components.interfaces.nsIPromptService）; 
 promptService.alert（window，From，gMsgCompose.compFields.from）; 
 promptService.alert（window，To，gMsgCompose.compFields.to）; 
} 
 
 window.addEventListener（compose-send-message，send_event_handler，true）; 
  

解决方案

您可以通过msgIdentity窗口小部件获取发送身份：

  var identityWidget = document.getElementById（'msgIdentity'）; 
 var fromIdentityKey = self.identityWidget.value; 
  

然后，使用客户经理查找身份信息：

  var acctMgr = Components.classes [@ mozilla.org/messenger/account-manager;1] 
 .getService（Components.interfaces.nsIMsgAccountManager）; 
 var accounts = acctMgr.accounts; 
 for（var i = 0; i< accounts.Count（）; i ++）{
 var account = accounts.QueryElementAt（i，Components.interfaces.nsIMsgAccount）; 
 
 var accountIdentities = account.identities; 
 
 for（var identCount = 0; identCount< accountIdentities.Count（）; identCount ++）{
 var identity = accountIdentities.QueryElementAt（identCount，
 Components.interfaces.nsIMsgIdentity） ; 
 
 if（identity.key == fromIdentityKey）{
 //身份找到
 alert（identity.email）; 
} 
} 
} 
  

I am working on a very simple Thunderbird extension, which is supposed to alert the name of the sender along with the names of the recipients whenever a mail is sent. The problem is that gMsgCompose.compFields.from field is empty in the below snippet (the .to field works as expected), which handles the "compose-send-message" event. What am I missing here?

function send_event_handler( evt ) {
var msgcomposeWindow = document.getElementById( "msgcomposeWindow" );
var msg_type = msgcomposeWindow.getAttribute( "msgtype" );

// do not continue unless this is an actual send event
if( !(msg_type == nsIMsgCompDeliverMode.Now || msg_type == nsIMsgCompDeliverMode.Later) )
  return;

var promptService = Components.classes["@mozilla.org/embedcomp/prompt-service;1"].getService(Components.interfaces.nsIPromptService);
promptService.alert(window, "From", gMsgCompose.compFields.from);
promptService.alert(window, "To", gMsgCompose.compFields.to);
}

window.addEventListener( "compose-send-message", send_event_handler, true );

解决方案

You can get the sending identity through the msgIdentity widget:

var identityWidget = document.getElementById('msgIdentity');
var fromIdentityKey= self.identityWidget.value;

Then, lookup identity information using the account manager:

var acctMgr = Components.classes["@mozilla.org/messenger/account-manager;1"]
                      .getService(Components.interfaces.nsIMsgAccountManager);
var accounts = acctMgr.accounts;
for (var i = 0; i < accounts.Count(); i++) {
  var account = accounts.QueryElementAt(i, Components.interfaces.nsIMsgAccount);

  var accountIdentities = account.identities;

  for(var identCount = 0; identCount < accountIdentities.Count(); identCount++) {
    var identity = accountIdentities.QueryElementAt(identCount,
                                                 Components.interfaces.nsIMsgIdentity);

    if(identity.key == fromIdentityKey) {
       // Identity found
       alert(identity.email);
    }
  }
}
