IE9脚本响应由于mime类型不匹配而被阻止 [英] IE9 script response blocked due to mime type mismatch
问题描述
我使用以下代码段将Google Fusion Table中的数据作为json加载.
I use the following code snippet to load data from google fusion table as json.
var fileref = document.createElement("script");
fileref.setAttribute("type", "text/javascript");
fileref.setAttribute("src", "http://tables.googlelabs.com/api/query?sql=select * from 588320&hdrs=false&jsonCallback=LoadTable");
在IE8，FF，Chrome中非常有效，但是现在IE9不知道如何处理回调，因为响应和mime类型不匹配. IE9在使用jsonCallback参数时会报告以下脚本错误，因为它不喜欢mime类型.
Works great in IE8, FF, Chrome, but now IE9 doesn't know how to handle the callback because the response and mime types don't match. IE9 reports the following script error when using jsonCallback param because it doesn't like the mime type.
SEC7112: Script from http://tables.googlelabs.com/api/query?sql=select * from 588320&hdrs=false&jsonCallback=LoadTable was blocked due to mime type mismatch.
是否有一种解决方法，我必须在本地托管src(或者我做错了什么)?
Is there a workaround short of me having to host the src locally (or am I doing something wrong)?

推荐答案
问题是Google正在发送X-Content-Type-Options: nosniff声明并返回没有JavaScript MIME类型的JavaScript文件.只能通过删除nosniff声明或通过修复MIME类型以指示该文件实际上是脚本的方式来解决此问题.
The problem is that Google is sending an X-Content-Type-Options: nosniff declaration and returning a JavaScript file without a JavaScript MIME type. This can only be fixed by either removing the nosniff declaration or by fixing the MIME type to indicate that the file is, in fact, script.
I've sent mail to Google about this one.
