Qt 写一个邮件发送程序

禾木瞎写 03-17 14:30 阅读 2

最近在完成一个邮箱代替的告警功能,写了一个邮件发送的demo

 

 

以下为代码:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include<QTcpSocket>
namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

    //用来等待服务器响应
    void  waitAndReadData();

    //功能函数
    void sendemil_fun();

    //登陆smtp服务器时所需的id和password,需要是base64编码格式
    QByteArray name;
    QByteArray passwd;

    //发送的标题和内容
    QByteArray s_Title;
    QByteArray s_Content;

    //发送邮件的邮件地址和接收地址,发送地址就是登陆的
    QByteArray sendemail;
    QByteArray rcvemail;


private:
    Ui::MainWindow *ui;
    QTcpSocket *m_pSocket;
    QString m_receiverData;
};

#endif // MAINWINDOW_H
#include "mainwindow.h"
#include "ui_mainwindow.h"

#include<QString>
#include <QtNetwork>
#include<QtDebug>
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    m_pSocket=new QTcpSocket();

    //此程序发送邮件作为主线程,会堵塞窗口,可以根据情况来使用子线程来运行,demo先使用主线程来完成邮件发送
    //点击发送,获取所需参数,进行发送
    connect(ui->pushButton,&QPushButton::clicked,this,[=]{
        this->m_pSocket = new QTcpSocket;
        this->name = ui->logid_lineEdit->text().toUtf8().toBase64();
        this->passwd = ui->logpasswd_lineEidt->text().toUtf8().toBase64();
        this->sendemail = ui->SendEmail_lineEdit->text().toUtf8();
        this->rcvemail=ui->Rcvemail_lineEdit->text().toUtf8();
        m_receiverData = ui->subject_lineEdit->text().toUtf8();
        s_Content = ui->textEdit_Text->toPlainText().toUtf8();
            sendemil_fun();

    });


 }


MainWindow::~MainWindow()
{
    delete ui;
    delete  m_pSocket;

}

void MainWindow::waitAndReadData()
{
        m_pSocket->waitForReadyRead(1000);
        m_receiverData = m_pSocket->readAll();

        //将其显示在服务器反馈TextEdit中
        qDebug()<<m_receiverData<<endl;
        ui->server_textEdit->append(m_receiverData);
}

void MainWindow::sendemil_fun()
{

        m_pSocket->connectToHost("smtp.qq.com",25,QTcpSocket::ReadWrite);  //连接qq邮箱

        m_pSocket->waitForConnected(1000);
        waitAndReadData();

        m_pSocket->write("helo yuanzhaoyi\r\n");
        waitAndReadData();

        m_pSocket->write("auth login\r\n");
        waitAndReadData();

        m_pSocket->write(name+"\r\n");  //写入用户名
        waitAndReadData();

        m_pSocket->write(passwd+"\r\n");  //写入密码
        waitAndReadData();

        m_pSocket->write("mail from: <"+sendemail+">\r\n"); //发送的邮箱
        waitAndReadData();

        m_pSocket->write("rcpt to: <"+rcvemail+">\r\n"); //接收的邮箱
        waitAndReadData();

        m_pSocket->write("data\r\n");  //开始写入
        waitAndReadData();

        m_pSocket->write("from:<"+sendemail+">\r\n");  //发送名称
        waitAndReadData();

        m_pSocket->write("to:<"+rcvemail+">");  //接收名称
        waitAndReadData();

        m_pSocket->write("data\r\n");
        waitAndReadData();

        m_pSocket->write("Subject:"+s_Title+"\r\n");  //标题
        m_pSocket->write("\r\n");

        m_pSocket->write(s_Content.append("\r\n")); //内容
        m_pSocket->write(".\r\n");
        waitAndReadData();
        
        m_pSocket->write("quit\r\n");
        m_pSocket->disconnect();
