从GMail的“已发邮件”获取电子邮件标题夹 [英] Get email headers from GMail's "Sent items" folder
问题描述
我的程序通过GMail向联系人发送电子邮件。通常这样做效果非常好,但是我们注意到有时候,我的程序认为发送的电子邮件实际上并不会到达Gmail,更不用说到达联系人了。我以为我可以在程序中添加一个支票来访问Gmail发送的项目文件夹,看看是否确实发送了每封电子邮件。
My program sends emails to contacts via GMail. Normally this works very well but we have noticed that sometimes an email which my program "thinks" it has sent doesn't actually arrive at Gmail, let alone arrive at the contacts. I thought that I might be able to add to the program a check which accesses the Gmail "sent items" folder to see whether each email has indeed been sent.
我有一些使用TIdPOP3组件的代码,但这会从收件箱下载头文件,而不是发送的项目。我的问题是,如何访问发送的项目文件夹中的标题?
I have some code using the TIdPOP3 component but this downloads headers from the Inbox, not from sent items. My question is, how can I access the headers in the sent items folder?
以下是我正在使用的代码。这只是测试代码,所以没有任何try / finally块等。
Following is the code that I am using. It's only test code so there aren't any try/finally blocks, etc.
with pop do
begin
host:= 'pop.gmail.com';
username:= 'someone@gmail.com';
password:= .....;
Port:= 995;
Connect;
if connected then
with i:= checkmessages downto 1 do
begin
msg.clear; // msg is of type TIdMessage
if retrieve (i, msg)
then listbox1.items.add (msg.subject)
end;
disconnect
end;
推荐答案
要获取与已发送邮件相关的信息,您可以请使用 Gmail imap_extensions
和 TIdIMAP4
组件。
To get the info related to the Sent Items you can use the Gmail imap_extensions
and the TIdIMAP4
component.
尝试此示例
{$APPTYPE CONSOLE}
uses
Classes,
SysUtils,
IdIMAP4,
IdSSLOpenSSL,
IdMessageCollection,
IdExplicitTLSClientServerBase;
procedure GetSentItems;
var
LIdIMAP4: TIdIMAP4;
LIdSSLIOHandlerSocketOpenSSL : TIdSSLIOHandlerSocketOpenSSL;
AMailBoxList: TStrings;
AMsgList: TIdMessageCollection;
i: integer;
begin
LIdIMAP4 := TIdIMAP4.Create(nil);
try
LIdSSLIOHandlerSocketOpenSSL := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
try
LIdSSLIOHandlerSocketOpenSSL.SSLOptions.Method := sslvSSLv3;
LIdIMAP4.IOHandler := LIdSSLIOHandlerSocketOpenSSL;
LIdIMAP4.Host := 'imap.gmail.com';
LIdIMAP4.Port := 993;
LIdIMAP4.UseTLS := utUseImplicitTLS;
LIdIMAP4.Username := 'user';
LIdIMAP4.Password := 'password';
LIdIMAP4.Connect;
try
//list the mail boxes
AMailBoxList:=TStringList.Create;
try
if LIdIMAP4.ListSubscribedMailBoxes(AMailBoxList) then
Writeln(AMailBoxList.Text);
finally
AMailBoxList.Free;
end;
AMsgList:=TIdMessageCollection.Create(TIdMessageItem);
try
if LIdIMAP4.SelectMailBox('[Gmail]/Enviados') then //This folder name is localizated in english use [Gmail]/Sent Mail
if LIdIMAP4.MailBox.TotalMsgs>0 then
if LIdIMAP4.UIDRetrieveAllEnvelopes(AMsgList) then
for i := 0 to AMsgList.Count-1 do
begin
//do your work here
Writeln(AMsgList[i].Subject); //list the subject of the sent items
end;
finally
AMsgList.Free;
end;
finally
LIdIMAP4.Disconnect;
end;
finally
LIdSSLIOHandlerSocketOpenSSL.Free;
end;
finally
LIdIMAP4.Free;
end;
end;
begin
try
GetSentItems;
except
on E: Exception do
Writeln(E.ClassName, ': ', E.Message);
end;
readln;
end.
