Question

我正在尝试使用Poco库发送电子邮件。平台 OS X ， Yosemite 10.10.2 我正在使用 Qt 5.3 32位。我按照here的官方说明进行操作，因为我使用的是32位Qt，并希望这些库是静态链接的，所以我使用了

./configure --omit=Data/ODBC,Data/MySQL --config=Darwin32

（我不需要MySQL / ODBC个模块。并且它正确地安装在/usr/local中，之后我链接了必要的动态库（PocoNet和PocoFoundation以及其他10个库），并尝试了以下代码，我发现{{3} }。我想要做的是从我的帐户本身发送电子邮件到我的Gmail帐户：

#include "MailSender.hpp"

#include <Poco/Net/MailMessage.h>
#include <Poco/Net/MailRecipient.h>
#include <Poco/Net/SMTPClientSession.h>
#include <Poco/Net/NetException.h>
#include <Poco/Net/SecureSMTPClientSession.h>
#include <Poco/Net/InvalidCertificateHandler.h>
#include <Poco/Net/AcceptCertificateHandler.h>
#include <Poco/Net/SSLManager.h>
#include <Poco/Net/SecureStreamSocket.h>
#include <Poco/Net/MailRecipient.h>

#include <iostream>
#include <QDebug>

using Poco::Net::InvalidCertificateHandler;
using Poco::Net::AcceptCertificateHandler;
using Poco::Net::Context;
using Poco::Net::SSLManager;
using Poco::Net::SecureStreamSocket;
using Poco::Net::SocketAddress;
using Poco::Net::SecureSMTPClientSession;
using Poco::Net::SMTPClientSession;
using Poco::SharedPtr;
using Poco::Net::MailMessage;
using Poco::Net::MailRecipient;
using namespace std;

MailSender::MailSender()
{
SharedPtr<InvalidCertificateHandler> pCert = new AcceptCertificateHandler(false);

string host = "smtp.gmail.com";
int port = 25;

Context::Ptr pContext = new Poco::Net::Context(Context::CLIENT_USE, "", "", "", Context::VERIFY_NONE, 9, false, "ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH");
SSLManager::instance().initializeClient(0, pCert, pContext);

Poco::Net::SecureSMTPClientSession* pSecure = new Poco::Net::SecureSMTPClientSession(host, port);
Poco::Net::SecureSMTPClientSession* pSession_ = new Poco::Net::SecureSMTPClientSession(host, port);

SecureStreamSocket* pSSLSocket = new SecureStreamSocket(pContext);
pSSLSocket->connect(SocketAddress(host, port));
pSecure = new SecureSMTPClientSession(*pSSLSocket);
pSession_ = pSecure;
pSecure->login();
if (!pSecure->startTLS(pContext))
   throw std::string("Failed to start TLS connection.");

std::string sUserName = "my_email_id";
std::string sPassword = "my_password";

pSession_->login(SMTPClientSession::AUTH_LOGIN, sUserName, sPassword);


string to = "my_email_id";
string from = "my_email_id";
string subject = "Your first e-mail message sent using Poco Libraries";
subject = MailMessage::encodeWord(subject, "UTF-8");
string content = "Well done! You've successfully sent your first message using Poco SMTPClientSession";
MailMessage message;
message.setSender(from);
message.addRecipient(MailRecipient(MailRecipient::PRIMARY_RECIPIENT, to));
message.setSubject(subject);
message.setContentType("text/plain; charset=UTF-8");
message.setContent(content, MailMessage::ENCODING_8BIT);



try {
    pSession_->sendMessage(message);
    pSession_->close();
} catch (Poco::Net::SMTPException &e) {
    qDebug() << e.displayText().c_str() << endl;
}
catch (Poco::Net::NetException &e) {
    qDebug() << e.displayText().c_str() << endl;
}

}

当我运行它时，我收到以下错误：

libc ++ abi.dylib：在Qt控制台中以类型Poco :: Net :: SSLException：SSL Exception 的未捕获异常终止。

Apple生成的故障转储显示了这一点：

不知何故，代码在pSSLSocket->connect(SocketAddress(host, port));

失败

我已将所有12个动态库与PocoNet，PocoNetSSL，PocoFoundation等相关联。

知道我如何解决这个问题吗？

对于构建，在静态构建配置中存在构建NetSSL示例的错误（并不重要，但OP不知道如何解决它），请参阅已解决的GitHub issue。

要发送电子邮件，请参阅Poco论坛上的SecureSMTPClientSession with GMail and SSL：

using Poco::Net::InvalidCertificateHandler;
using Poco::Net::AcceptCertificateHandler;
using Poco::Net::Context;
using Poco::Net::SSLManager;
using Poco::Net::SecureStreamSocket;
using Poco::Net::SocketAddress;
using Poco::Net::SecureSMTPClientSession;
using Poco::Net::SMTPClientSession;
using Poco::SharedPtr;

SharedPtr<InvalidCertificateHandler> pCert = new AcceptCertificateHandler(false);
Context::Ptr pContext = new Poco::Net::Context(Context::CLIENT_USE, "", "", "", Context::VERIFY_NONE, 9, false, "ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH");
SSLManager::instance().initializeClient(0, pCert, pContext);

SecureStreamSocket* pSSLSocket = new SecureStreamSocket(pContext);
pSSLSocket->connect(SocketAddress(sSmtpServer, nSmtpPort));
pSecure = new SecureSMTPClientSession(*pSSLSocket);
pSession_ = pSecure;
pSecure->login();
if (!pSecure->startTLS(pContext))
   throw std::string("Failed to start TLS connection.");

pSession_->login(SMTPClientSession::AUTH_LOGIN, sUserName, sPassword);
pSession_->sendMessage(*pSelectedMailMessage_);
pSession_->close();

另见NetSSL Mail example：

SharedPtr<InvalidCertificateHandler> pCert = new ConsoleCertificateHandler(false); // ask the user via console
Context::Ptr pContext = new Context(Context::CLIENT_USE, "", "", "", Context::VERIFY_RELAXED, 9, true, "ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH");
SSLManager::instance().initializeClient(0, pCert, pContext);

MailMessage message;
message.setSender(sender);
message.addRecipient(MailRecipient(MailRecipient::PRIMARY_RECIPIENT, recipient));
message.setSubject("Hello from the POCO C++ Libraries");
std::string content;
content += "Hello ";
content += recipient;
content += ",\r\n\r\n";
content += "This is a greeting from the POCO C++ Libraries.\r\n\r\n";
std::string logo(reinterpret_cast<const char*>(PocoLogo), sizeof(PocoLogo));
message.addContent(new StringPartSource(content));
message.addAttachment("logo", new StringPartSource(logo, "image/gif"));

SecureSMTPClientSession session(mailhost);
session.login();
session.startTLS(pContext);
if (!username.empty())
{
    session.login(SMTPClientSession::AUTH_LOGIN, username, password);
}
session.sendMessage(message);
session.close();

Poco无法发送电子邮件
