Question

我有一个运行Kiosk屏幕的JavaScript WebApp。它每1小时调用一个远程服务器上的PHP页面来更新应用程序上的信息。当我使用天气更新时，这非常有效，但是当我用它来发送报告失败时。

如果我只是在Web浏览器中使用相同的URL，那么它将向文本文件中添加一条记录，但是当Java Script调用它时，它不起作用。注意：我知道定时器时间非常短，这仅用于测试目的......]

注意我已经尝试正确添加PHP，在编辑器中保存它没关系它没有正确显示，对不起，请告诉我你是否需要其余的PHP代码和我将PM

JavaScript Kiosk代码：

    {
    var t=setTimeout("updateLogReport()",3000);
    }

        function updateLogReport()
            {   
            // New reporting system
            // This simply sends information to a remote php page which deals with the given data
            var response = null; 
            var connection = new ActiveXObject("Microsoft.XMLHTTP"); 
            try 
            { 
                connection.open("GET", "http://www.EXAMPLE.com/EXAMPLE/reporting/remote_reporting_answer.php?type=Java_Checkin&reportingDisplayPricesDynamic=yes&machine=Display", false); 
                connection.send(); 
                if(connection.readyState == 4) response = connection.responseText; 
            }        
            catch(e) 
            { 
                // Alerts disabled for real time deployement
                alert("ERROR (reporting): The remote host could not be found or the connection was refused."); 
                return false; 
            } 
            alert(response);

                // Recall the timer
                timerLogReport()
        }

将显示“警报”，它将在PHP脚本的末尾显示您将在下面看到的响应，但是它拒绝将文本添加到文本文件中，尽管我要键入

http://www.EXAMPLE.com/EXAMPLE/reporting/remote_reporting_answer.php?type=Java_Checkin&reportingDisplayPricesDynamic=yes&machine=Display

直接进入浏览器，它会将文本添加到文件

PHP代码：

<?php
// Receives information sent from 

// This information can be used to help problem solve and
// indentify run times etc

            // File to save to
             $file = 'reports.html';

            // Calculate the date
             $time = date('d-m-Y h:m:s');

             // Get variables sent from the machine
             $machine = $_GET['machine'];
             $type = $_GET['type'];
             $reportingDisplayPricesDynamic = $_GET['reportingDisplayPricesDynamic'];
             $softwareVersion = $_GET['softwareVersion'];

             // Set the color of the text
             if($type=="Startup") {
                 $fontColor = "#33c1bc";
             }

             else if($type=="Checkin") {
                 $fontColor = "#52b131";                 
             }

             else if($type=="Java_Checkin") {
                 $fontColor = "#ffcc00";                 
             }

             else {
                 // For everything else set to red
                 $fontColor = "#ee2617";
             }

             // Text to add to file
                $error = "

                ";

             // Write the contents to the file, 
             // using the FILE_APPEND flag to append the content to the end of the file

             file_put_contents($file, $error, FILE_APPEND | LOCK_EX);

             // Echo a success message, this will be displayed in the application
             echo "Time stamp :: " . $time;
        ?>

PHP和JavaScript相互依赖，但不能一起工作
