javascript – XHR.send(文件参数)？

xhr.setrequestHead('X_FILename',file.Name)
xhr.send(filE);
xhr.setrequestHeader("Content-type","application/x-www-form-urlencoded");
xhr.send(params);

如果您依赖支持FormData的浏览器,您可以使用下面的代码(JavaScript)：

var formData = new FormData();
formData.append('param1','myParam');
formData.append('param2',12345); 
formData.append('uploadDir','public-data');  
formData.append('myfile',filE);

xhr.send(formData);

然后,在服务器端,您可以使用此代码(php)访问您的变量：

<?
  $param1 = $_POST['param1']; //myParam
  $param2 = $_POST['param2']; //12345
  $uploaddir = $_POST['uploadDir']; //public-data
  $filename = $_FILES['myfile']['name'];
  $fileZise = $_FILES['myfile']['size'];
  $uploaddir = getcwd().DIRECTORY_SEPARATOR.$uploaddir.DIRECTORY_SEPARATOR;
  $uploadfile = $uploaddir.basename($fileName);       
  move_uploaded_file($_FILES['file']['tmp_name'],$uploadfilE);
  echo $filename.' ['.$fileZise.'] was uploaded successfully!';
?>

要获取$_FILES [‘myfile’]的所有参数,请使用var_dump($_ FILES [“myfile”])
