如果服务器在使用Uploadify上传文件时返回错误(HTTP响应代码!= 200),则上传的文件会显示红色背景,并显示如下信息:
file.jpg (52.78KB) - HTTP Error
表示存在HTTP错误。但这对用户来说并不是很有用。如何让它显示更详细的错误消息?例如:'不是有效图像'或'配额已满'?
我正在考虑在HTTP响应正文中传递这些消息,但是Uploadify没有接收它们。有没有已知的方法将错误消息传递回Uploadify?

在uploadify论坛中查看这两篇关于如何处理错误的帖子
onError to display what's happening 和 Upload script error reporting
那里有很多有用的信息..
<强> 更新 强>
以下似乎为我做了诀窍......
'onComplete': function(a, b, c, d, e){
if (d !== '1')
{
alert(d);
}
else
{
alert('Filename: ' + c.name + ' was uploaded');
}
}
加上此版本的uploadify脚本
<?php
if (!empty($_FILES))
{
$tempFile = $_FILES['userfile']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
$targetFile = str_replace('//','/',$targetPath) . $_FILES['userfile']['name'];
move_uploaded_file($tempFile,$targetFile);
switch ($_FILES['userfile']['error'])
{
case 0:
$msg = ""; // comment this out if you don't want a message to appear on success.
break;
case 1:
$msg = "The file is bigger than this PHP installation allows";
break;
case 2:
$msg = "The file is bigger than this form allows";
break;
case 3:
$msg = "Only part of the file was uploaded";
break;
case 4:
$msg = "No file was uploaded";
break;
case 6:
$msg = "Missing a temporary folder";
break;
case 7:
$msg = "Failed to write file to disk";
break;
case 8:
$msg = "File upload stopped by extension";
break;
default:
$msg = "unknown error ".$_FILES['userfile']['error'];
break;
}
}
if ($msg)
{ $stringData = "Error: ".$_FILES['userfile']['error']." Error Info: ".$msg; }
else
{ $stringData = "1"; } // This is required for onComplete to fire on Mac OSX
echo $stringData;
?>

不幸的是,onUploadError事件无权访问响应主体。根据我的意识,你必须返回200状态并处理onUploadSuccess中的错误。
以下是我的表现:
'onUploadSuccess' : function(file, data, response) {
var responseObj = JSON.parse(data);
if(responseObj.error_message)
{
$("#" + file.id).hide(); // this will hide the misleading "complete" message..
alert(responseObj.error_message);
return;
}
}
或者更好的是,您可以将错误消息替换为“完整”消息,如下所示:
'onUploadSuccess' : function(file, data, response) {
var responseObj = JSON.parse(data);
if(responseObj.error_message)
{
$("#" + file.id).find('.data').css('color', 'red').html(' - ' + responseObj.error_message);
return;
}
console.log(file, data, response);
}

我遇到了同样的问题。搜索了几个小时后,我发现了问题。我在“internet Options-&gt; Lan设置”中设置了“代理服务器”,当我将其恢复为默认状态时,uploadify再次工作。

对于uploadify版本3.0+,请查看onUploadSuccess选项 - 特别是传入的名为data的变量 - 将包含服务器回显的任何内容。如果您回显JSON,请记住解码它:
...
'onUploadSuccess' : function(file, data, response) {
if (response){
var json_data=JSON.decode(data);
/* code here */
}
},
....
