如何使用QT 发送匿名邮件

要发送匿名邮件，您可以在 QT 中使用 SMTP 协议来发送邮件。以下是一个简单的示例代码，可以帮助您了解如何使用 QT 发送匿名邮件：

#include <QCoreApplication>
#include <QtNetwork/QSslSocket>
#include <QtNetwork/QSslConfiguration>
#include <QtNetwork/QHostInfo>
#include <QtNetwork/QHostAddress>
#include <QtNetwork/QNetworkInterface>
#include <QtNetwork/QNetworkAccessManager>
#include <QtNetwork/QNetworkReply>
#include <QByteArray>
#include <QTextStream>
#include <QDateTime>
#include <QDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QString smtp_server = "smtp.gmail.com";  // SMTP 服务器地址
    int smtp_port = 465;  // SMTP 服务器端口号（SSL）

    QString user_email = "your_email@gmail.com";  // 发送方邮箱地址
    QString user_name = "Anonymous";  // 发送方姓名（可选）
    QString user_password = "your_password";  // 发送方邮箱密码

    QString receiver_email = "receiver_email@gmail.com";  // 接收方邮箱地址
    QString subject = "Test Email";  // 邮件主题
    QString body = "This is a test email from QT!";  // 邮件正文

    QString boundary = "ChitGPT-2021";  // 邮件分隔符
    QString message;

    // 构造邮件头部信息
    message += "From: " + user_name + " <" + user_email + ">\n";
    message += "To: " + receiver_email + "\n";
    message += "Subject: " + subject + "\n";
    message += "Date: " + QDateTime::currentDateTime().toString("ddd, dd MMM yyyy hh:mm:ss +0800") + "\n";
    message += "MIME-Version: 1.0\n";
    message += "Content-Type: multipart/alternative; boundary=" + boundary + "\n\n";

    // 构造邮件正文
    message += "--" + boundary + "\n";
    message += "Content-Type: text/plain; charset=UTF-8\n\n";
    message += body + "\n\n";
    message += "--" + boundary + "--\n";

    // 连接 SMTP 服务器
    QSslSocket *socket = new QSslSocket();
    socket->connectToHostEncrypted(smtp_server, smtp_port);
    if (!socket->waitForConnected()) {
        qDebug() << "Error: " << socket->errorString();
        return a.exec();
    }

    // SSL 配置
    QSslConfiguration config = socket->sslConfiguration();
    config.setProtocol(QSsl::TlsV1_2);
    socket->setSslConfiguration(config);

    // 接收服务器返回的信息
    if (!socket->waitForReadyRead()) {
        qDebug() << "Error: " << socket->errorString();
        return a.exec();
    }

    // 发送邮件认证信息
    QTextStream textStream(socket);
    textStream << "EHLO " + QHostInfo::localHostName() + "\r\n";
    textStream << "AUTH LOGIN\r\n";
    textStream << QByteArray().append(user_email.toUtf8()).toBase64() + "\r\n";
    textStream << QByteArray().append(user_password.toUtf8()).toBase64() + "\r\n";
    textStream << "MAIL FROM: <" + user_email + ">\r\n";
    textStream << "RCPT TO: <" + receiver_email + ">\r\n";
    textStream << "DATA\r\n";

    // 发送邮件内容
    textStream << message + "\r\n.\r\n";
    textStream << "QUIT\r\n";

    // 接收服务器返回的信息
    if (!socket->waitForReadyRead()) {
        qDebug() << "Error: " << socket->errorString();
        return a.exec();
    }

    // 关闭连接
    socket->close();
    delete socket;

    qDebug() << "Email has been sent successfully!";
    return a.exec();
}

请替换示例代码中的 SMTP 服务器地址、端口号、发送方邮箱地址、密码、接收方邮箱地址、邮件主题、邮件正文等信息，以便发送您自己的匿名邮件。注意，由于涉及到邮箱密码和敏感信息，请妥善保管好您的代码和密码，以免被他人恶意利用。
