尝试在新浏览器中打开 pdf 文件 window

Question

无法在新浏览器中打开 PDF window。我使用 php 代码设置 PDF 并打开它！

<?php
if (($_POST['name_check']=="in") || ($_GET['type']=="in")){
 header('Content-Type: application/pdf; charset=windows-1257');
 header("Content-Disposition: inline; ");
 header('Accept-Ranges: bytes');
 $file_type = "in";
 $flag = 0;
}
else{
 header('Content-Type: application/pdf; charset=windows-1257');
 header("Content-Disposition: inline;");
 header('Accept-Ranges: bytes');
 $file_type = "out";
 $flag = 1;
}

?>
<?php session_start();  
 if (((isset($_SESSION['UserID'])) and (isset($_SESSION['Pin_code']))) and (isset($_COOKIE['CookieMy']))){
  $form='<form action="login.php" method="get" style="width: 900px;margin: -1px auto -57px auto;" class="exit_but">
  <input type="submit" name="exit" value="EXIT" style="margin-left: 800px;"></form>';
  echo $form;   
 } else {
  header("Location: login.php"); 
 }
?>

  $(document).ready(function(){
    $(document).bind('mousemove keydown scroll click', function(){
   clearTimeout(idleTimer);
   idleState = false;
   idleTimer = setTimeout(function(){
      idleState = true;
      window.location.href = "login.php"

我正在尝试在新的 (Chrome) 浏览器 window 中打开 PDF 文件。

document.action =window.open('date_PDF.php', 'newWindow', 'width=1000, height=1000');

错误是无法加载 PDF 文档。

当我执行 document.getElementById("edit").action ="date_PDF.php"; 时，它会打开 pdf。

我从 ftp 服务器获取 PDF 文件，然后在 date_PDF.php @readfile($ftp_path_pdf_in.$qwerty);

上显示它

问题出在哪里？谢谢！

Answer 1

您尚未定义 name_check html 元素。此外，您还没有在 url 中传递 'type' 参数。我认为 name_check 和类型出现在您打开 pdf 文件的页面上。

如果您想使用 window.open 打开 pdf 文件，那么您应该使用 url: date_PDF.php?type=in

在 readfile 语句之后你应该有一个 exit 语句。请参阅 readline 函数的示例：http://php.net/manual/en/function.readfile.php#refsect1-function.readfile-examples
