IE 11:发送多部分表单数据请求时出错:流意外结束 [英] IE 11: Error while sending Multipart Form Data request: Stream ended unexpectedly

问题描述

我正在尝试使用jQuery AJAX调用上传文件以及其他一些表单字段.

I am trying to upload files along with some other form fields using jQuery AJAX calls.

这是调用服务器上URL的常用功能:

This is a common function that calls the URL on the server:

function uploadDocument(rquestURL,formId,callback){
        $.ajax({
            type : 'POST',
            url : rquestURL,
            cache:false,
            processData:false,
            contentType:false,
            data : new FormData($("#"+formId)[0])
        }).done(function(response) {
            callback(response);
        });
}

通过浏览器的开发工具进行检查时，以下是各自的请求内容:

On examining from the dev tools from browsers, these are the respective request contents:

从IE11

-----------------------------7dfad39402e6
Content-Disposition: form-data; name="subject"

Test
-----------------------------7dfad39402e6
Content-Disposition: form-data; name="message"

Test test
-----------------------------7dfad39402e6
Content-Disposition: form-data; name="announcementAttachment"; filename=""
Content-Type: application/octet-stream

<Binary File Data Not Shown>
---------------------------7dfad39402e6

Chrome

------WebKitFormBoundaryp8rj3ArKDsbYw0BZ
Content-Disposition: form-data; name="subject"

Test
------WebKitFormBoundaryp8rj3ArKDsbYw0BZ
Content-Disposition: form-data; name="message"

Test test
------WebKitFormBoundaryp8rj3ArKDsbYw0BZ
Content-Disposition: form-data; name="announcementAttachment"; filename=""
Content-Type: application/octet-stream


------WebKitFormBoundaryp8rj3ArKDsbYw0BZ--

在服务器端，我们将请求解析为:

On server side, we are parsing the request as:

import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

final FileItemFactory factory = new DiskFileItemFactory();
final ServletFileUpload fileUpload = new ServletFileUpload(factory);

if (ServletFileUpload.isMultipartContent(request)) {
        // get the request content and iterate through
        items = fileUpload.parseRequest(request);
}

该代码在Chrome和Firefox上运行正常，但是当我从IE11尝试时会引发以下异常.

The code works fine from Chrome and Firefox, but throws the below exception when I tried from IE11.

javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: org.apache.commons.fileupload.FileUploadException: Stream ended unexpectedly

我提到了这些SO问题，但徒劳无功.

I referred to these SO questions but in vain.

• Java-IE中的FormData抛出org.apache .commons.fileupload.MultipartStream $ MalformedStreamException:流意外结束
• Grails多部分服务流意外结束

• Java - FormData in IE throwing org.apache.commons.fileupload.MultipartStream$MalformedStreamException: Stream ended unexpectedly
• Grails Multipart Service Stream ended unexpectedly

任何有用的指针都值得赞赏.谢谢.

Any useful pointers are appreciated. Thanks.

推荐答案

发现了一个奇怪的问题.解决方法就是这样.

Turned out a weird issue. This is how it's resolved.

• 我们在表单末尾有一个复选框.当我们没有选择任何复选框时，就会发生提到的问题.该请求的格式不正确，因此服务器引发了错误.
• 在表单末尾添加了一个隐藏字段(确保这是最后一个表单字段)，并为其分配了一些值.

就是这样.像魔术一样工作！

That' it. Worked like a magic!
