Resource interpreted as Document but transferred with MIME type application/json ...

今天发布一个项目的时候，遇到了一个奇怪的问题，一个后台管理系统的excel导出。在我的本地测试中，导出没有任何问题，但是发布到服务器之后，第一次导出没有问题，多次导出之后，浏览器直接白屏。从服务器后端找错误，被其他无关的错误所误导。最终，在浏览器的调试中发现了这样一句话：Resource interpreted as Document but transferred with
MIME type applic。。。， 网上搜索了一下，找到了一条英文的答案，如下：

Dear Dimitar,

Thanks for the quick answer, I should defenitely check SO before posting here, sorry for that. The first link was sort of helpful but rather incomplete I’m afraid.

The good news is that there is a solution that worked for me: to change the server response MIME to 

text/html

. 

args.event.response

 is
then a string containing the JSON; I can parse it. However I’m fortunate enough to have control over the server process, that might not be a suitable solution in everey case.

Another proposed solution was to remove 

multipart/form-data

,
but this is not possible when uploading files.

Another one wat to add a query string to the URL, didn’t work for me (I was suspicious about this solution anyway).

Finally, apparently, the definite solution is to use 

$.post

 instead
of 

ajaxSubmit

. However I suspect this call is buried
somewhere in 

jqxfileupload.js

 or 

jquery-1.11.1.min.js

.

Here’s the stack trace I get from Chromium, if it is of any value:

Resource interpreted as Document but transferred with MIME type application/json: “http://localhost:8080/…”.

a.extend._uploadFile @ jqxfileupload.js:7

(anonymous function) @ jqxfileupload.js:7

m.event.dispatch @ jquery-1.11.1.min.js:3

r.handle @ jquery-1.11.1.min.js:3

Thank you very much, jqxWidgets is fantastic,

Robert

大概意思是：这个罗伯特对这个问题有几种解决方案：

1.把server response MIME改成

text/html

. 

args.event.response

。这种方法在处理json
的时候有效，但是可能不是一种好方法。

2.去掉

multipart/form-data

, 但是上传文件的时候没用。

3.用json的$.post 方法替代ajaxSubmit

在我的页面中是用的get方法去请求导出接口，改成post之后，问题解决。
