我想使用 qt5 界面中的“QNetworkAccessManager”将数据发布到我的 php 文件中，但数据没有发送。我正在尝试保存发送到数据库的数据。当我运行 php 文件时，它正在录制。当我想发送数据不去。我试过这种方法，没有结果。

senddata.cpp 代码

 #include "sendata.h"
 #include "ui_sendata.h"
 #include <QUrlQuery>
 #include "mainwindow.h"
 QNetworkRequest request;
 sendata::sendata(QWidget *parent) :
 QDialog(parent),
 ui(new Ui::sendata)
{
ui->setupUi(this);

nams= new QNetworkAccessManager(this);


request.setUrl(QUrl("http://localhost/phpserver/mysqlsorgu.php"));
request.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("application/x-www-form-urlencoded"));
replys = nams->get(request);

}

void sendata::onResult()
{
replys->deleteLater();
   if (replys->error() != QNetworkReply::NoError) {
       qDebug() << "Hataa!";
       return;
   }

   qDebug() << "Response!";
  }

  void sendata::on_pushButton_clicked()
 {


 query.clear();

 query.addQueryItem("pname", ui->nameline->text());
 query.addQueryItem("pusername", ui->usernameline->text());
 query.addQueryItem("pemail", ui->emailline->text());
 query.addQueryItem("pphone", ui->phoneline->text());
 query.addQueryItem("pwebsite", ui->websiteline->text());
 query.addQueryItem("padress", ui->adressline->text());
 query.addQueryItem("pcompany", ui->companyline->text());
 QByteArray postData;
 postData.append(query.toString());
 nams->post(request,postData);
//nams->post(request, query.query().toUtf8());

}

发送数据.php 代码

   <?php

header("Content-Type:application/json");

        $database_name     = 'employer';
        $database_user     = 'root';
        $database_password = '';
        $database_host     = 'localhost';
    
        
        $name = $_POST['pname'];
        $username = $_POST['pusername'];
        $email = $_POST['pemail'];
        $phone = $_POST['pphone'];
        $website = $_POST['pwebsite'];
        $adress = $_POST['padress'];
        $company = $_POST['pcompany'];
        
        
    $conn = mysqli_connect($database_host, $database_user,$database_password,$database_name );
 if(!$conn) {
 die("Error, could not connect: " . mysqli_connect_error());
 }
 else{

   $sql = "INSERT INTO data (name, username, email,phone,website,address,company) VALUES 
   ('$name', '$username', '$email', '$phone', '$website', '$adress', '$company')";
   if(mysqli_query($conn, $sql)){
   echo "Records added successfully.";
   }  } mysqli_close($conn);?>
