不断上传php $ _FILES错误= 3（部分上传） [英] keep getting upload php $_FILES error = 3 (partially uploaded)

问题描述

我正在使用Yii框架的dropzone扩展来由注册用户上传一些文件。一切正常，但有些用户尝试上传的某些文件的返回错误= 3，这是在上传的文件仅部分上传的情况下发生的。

I am using dropzone extension for Yii framework to upload some files by registered users. Everything working well but some users for some files that they trying to upload it's return error = 3 which it's happens when the uploaded file was only partially uploaded.

$file_error = $_FILES['Project']['error']['file'];
if ($file_error != 0) {
            mail('[e-mail]', 'fileError',json_encode($_FILES['Project']));
}

我从此功能收到很多电子邮件

i'am receiving a lot of emails from this function

接收到JSON

{"name":{"file":"3.jpg"},"type":{"file":""},"tmp_name":{"file":""},"error":{"file":3},"size":{"file":0}}

我如何调试此错误并知道导致此错误发生的情况？

如果用户在上载时刷新页面，则会发生此错误
1-。
2-如果用户取消上传（我的网站中没有取消选项）。
3-如果上传时互联网连接丢失。

how can i debug this error and know the cases that make this error happened ?

This error happened 1- if the user refresh the page while uploading. 2- if the user cancel the upload (there is no cancel option in my site). 3- if the internet connection lost while uploading.

我还在寻找其他情况。

推荐答案

在我的情况下，使用缓慢的Internet连接上传中/大文件时发生了部分上传问题。

in my case, the "partially uploaded" problem happened when uploading medium/large files using a slow internet connection.

最适合我的解决方案是在httpd.conf文件中设置了一些Apache配置：

The solution that works for me was set some Apache configurations in httpd.conf file:

TimeOut 300
KeepAliveTimeout 10
RequestReadTimeout handshake=0 header=20-1200,MinRate=200 body=20,MinRate=200
