我正在使用外部库EASendMail使用 gmail 作为 SMTP 服务器发送电子邮件。
导致错误的行
oSmtp->LicenseCode = _T("TryIt");
安装外部库的链接。
#include "stdafx.h"
#include <iostream>
#include "easendmailobj.tlh"
#include <string>
using namespace EASendMailObjLib;
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
string Lrecipient_email = "foobar@hotmail.com";
::CoInitialize( NULL );
IMailPtr oSmtp = NULL;
oSmtp.CreateInstance( "EASendMailObj.Mail");
oSmtp->LicenseCode = _T("TryIt"); //error is here
// Set your gmail email address
oSmtp->FromAddr = _T(" mygmailacc@gmail.com");
// Add recipient email address
oSmtp->AddRecipientEx( _T(recipient_email.c_str()), 0);
// Set email subject
oSmtp->Subject = _T("Payment of Desposit Required");
// Set email body
oSmtp->BodyText = _T("Dear Customer , Please pay your deposit now !!!");
// Gmail SMTP server address
oSmtp->ServerAddr = _T("smtp.gmail.com");
// If you want to use direct SSL 465 port,
// Please add this line, otherwise TLS will be used.
// oSmtp->ServerPort = 465;
// detect SSL/TLS automatically
oSmtp->SSL_init();
// Gmail user authentication should use your
// Gmail email address as the user name.
// For example: your email is "gmailid@gmail.com", then the user should be "gmailid@gmail.com"
oSmtp->UserName = _T("username");
oSmtp->Password = _T("password");
_tprintf(_T("Start to send email via gmail account ...\r\n" ));
if( oSmtp->SendMail() == 0 )
{
_tprintf( _T("email was sent successfully!\r\n"));
}
else
{
_tprintf( _T("failed to send email with the following error: %s\r\n"),
(const TCHAR*)oSmtp->GetLastErrDescription());
}
if( oSmtp != NULL )
oSmtp.Release();
return 0;
}
我不知道为什么会收到以下错误:
Unhandled exception at 0x7558c41f in SendEmail.exe: Microsoft C++ exception: _com_error at memory location 0x0040f4ac..
MS Studio 调试器将此显示为文件中的错误来源:easendmailobj.tli
错误 1
Interface* operator->() const
{
if (m_pInterface == NULL)
{
_com_issue_error(E_POINTER);
}
return m_pInterface;
}
错误 2
inline void IMail::PutLicenseCode ( _bstr_t pVal ) {
HRESULT _hr = put_LicenseCode(pVal);
if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
}
