从Firefox 74/75发布多部分/表单数据并在服务器端使用Apache AJP连接器时出现java.io.IOException [英] java.io.IOException when posting multipart/form-data from Firefox 74 / 75 and using Apache AJP connector on server side
问题描述
从Firefox 74版本开始，使用"multipart/form-data"表单发送的文件大小超过1.8 MB的文件引发了错误.
Since version 74 of Firefox, file sent using "multipart/form-data" form with file size above about 1.8 MB are raising error.
注意:使用AJAX发送的文件运行正常.只有多部分表单提交才引起问题.
Note: file sent using AJAX are working fine. Only multipart form submit cause the issue.
HTML代码:
<form name="formUpload" action="AdminImportInssAseg" method="POST"
enctype="multipart/form-data" onsubmit="return validate_form(this);">
<table class="centrado green">
<tr>
<td><input type="File" name="miadjuntoSolvenciaX" class="mdt">
</td>
</tr>
<tr>
<td align="center" colspan="2"><a href="#"
onClick="if(validate_form(formUpload)) formUpload.submit();"
title="Importar el archivo"><img alt='' border="0"
src="./images/add.gif" height="30"></a></td>
</tr>
</table>
</form>
Java代码:
FileItemIterator iter = upload.getItemIterator(request);
while (iter.hasNext()) {
FileItemStream item = iter.next();
if (item.isFormField()) {
continue;
} else {
filename = item.getName();
contentType = item.getContentType();
String inputLine;
InputStream fis = item.openStream();
BufferedReader in = null;
in = new BufferedReader(new InputStreamReader(fis,"ISO-8859-1"));
while ((inputLine = in.readLine()) != null) {
try{
out.println("*"+inputLine+"*<br>");
}
catch (Exception e){
out.println("<p>Error: <b>"+e.getMessage() + "</b></p>");
}
}
fis.close();
}
}
我可以看到它读取了文件，但是当使用Firefox 74+时，文件却在中间失败了.
I can see it reads the file, but fails in the middle of it when using Firefox 74+.
错误堆栈跟踪可在此消息下方找到.
Error stack trace can be found below this message.
使用Firefox 73或更低版本时，一切正常.
When using Firefox 73 or lower everything works fine.
直接连接到Tomcat端口(不使用AJP连接器)时，一切正常(包括Firefox 74/75).
When connecting directly to Tomcat port (not using AJP connector), everything works fine (inlcuding with Firefox 74/75).
代码已经使用了十多年. Java编码，Apache和Tomcat最近尚未修改.
Code has been used for more than a decade. Java coding, Apache and Tomcat have not been modified recently.
Server version: Apache/2.4.43 (Linux/SUSE)
我注意到保存的临时"文件总是被切成188416字节(而上传的文件实际上更大).
I noticed that the "temporary" file saved is always cut at 188416 bytes (while the uploaded file is actually bigger).

问题是由生产用户报告的，但是我可以在本地复制它.
Issue was reported by a production user, but I could reproduce it locally.
仅使用 Firefox 74和75 会导致此问题(我在Firefox 71-> 75上进行了测试)，因此它必须与Firefox中的某些更改链接(至少是Linux和Windows版本).在Firefox发行说明中找不到解释. 任何人都知道可能导致此问题的原因以及如何解决此问题.
Only the use of Firefox 74 and 75 causes the problem (I tested with Firefox 71 -> 75), so it must be linked to some change in Firefox (Linux and Windows versions at least). I could not find explanation looking at Firefox release notes. Anyone getting ideas of what could cause this and how this can be fixed.
过去我已经遇到了与Firefox升级相关的问题，通常修复了通过"about:config"更改Firefox配置中的某些值的问题.诀窍是找到正确的参数进行更新...
I have already had Firefox upgrade related issues in the past, usually fixed changing some values in Firefox config via "about:config". The trick is finding the right parameter to update...

推荐答案
使用com.oreilly.servlet.MultipartRequest失败. 使用org.apache.commons.fileupload失败.
Was failing using com.oreilly.servlet.MultipartRequest. Was failing using org.apache.commons.fileupload.
使用Java Servlet技术并将maxFileSize设置为更高(默认值为2MB)使其正常工作.
Got it working using Java Servlet Technology and setting maxFileSize higher (default is 2MB).
我不明白为什么它可以与旧版本的Firefox兼容，而不能与新版本的Firefox兼容...但是我的问题已解决.
I can't understand why it works with old versions of Firefox and not with new ones... but my problem is solved.
@WebServlet("/AdminImportInssAseg")
@MultipartConfig (fileSizeThreshold=1024*1024*10, // 1 MB
maxFileSize=1024*1024*50, // 50 MB
maxRequestSize=1024*1024*100) // 100 MB
public class AdminImportInssAseg extends HttpServlet {
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException,
IOException {
Part filePart = request.getPart("miadjuntoSolvenciaX"); // Retrieves <input type="file" name="file">
filename = filePart.getName();
fileSize = filePart.getSize();
contentType = filePart.getContentType();
InputStream fis = filePart.getInputStream();
BufferedReader in = null;
in = new BufferedReader(new InputStreamReader(fis,"ISO-8859-1"));
String inputLine;
while ((inputLine = in.readLine()) != null) {
...
}
fis.close();
filePart.delete();
}
}
