用于Firefox的swfupload中的UploadError 403

标签: java tomcat swfupload

我正在尝试使用swfuploder上传文件,它在IE中工作正常。但它在Firefox中获取“UploadError 403”。我正在使用apache-tomcat-6.0.16并且也无法访问.htaccess文件。

这是我用于swfupload的代码。

我已尝试使用绝对和相对网址“upload_url”但出现相同的错误“uploadError 403”。但它适用于IE。

2 个答案:

答案 0 :(得分:1)

HTTP状态代码403表示Forbidden。这是一个身份验证错误。该请求需要经过身份验证的用户(登录用户),但会话中的用户不在,或者找不到关联的会话。

我从未使用过SWFUpload,但看起来它没有将jsessionid cookie连同请求一起传递给服务器端,因此服务器端无法识别客户端。谷歌搜索“swfupload jsessionid”也知道你不是唯一遇到这个特殊问题的人。要解决此问题,您需要在设置中将jsessionid附加到网址:

upload_url: "upload_pages/uploader.jsp;jsessionid=${pageContext.session.id}",

那说,以下一行

post_params: {"PHPSESSID" : ""},

看起来也很可疑。什么是在JSP / Servlet环境中执行的空PHP会话ID?你是否在复制其他人的代码时忽略/忘记了这一点?

我有一个类似的问题,但在apache / PHP中。所以我在这里链接一个可能的解决方案。

从我发现到目前为止,安装了安全扩展的服务器上的会话身份验证(即会话保护/加密)似乎是安全问题,这使得服务器认为html页面和swf上传器是不同的用户因此导致403错误。 http://imagevuex.com/forum/viewtopic.php?f=27&t=4337

同时检查mod_security是否已禁用并尝试添加这些.htaccess设置,它似乎适用于某些人。

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

另一个解决方案似乎是(也是.htaccess),来自http://www.ramirezcobos.com/2010/01/05/swfupload_0_0-error-http-status-403-solved/

SetEnvIfNoCase Content-Type “^multipart/form-data;” “MODSEC_NOPOSTBUFFERING=Do not buffer file uploads”
