IE中Json响应下载(7~10) [英] Json response download in IE(7~10)

问题描述

我正在尝试上传文件并返回有关文件属性(名称、大小等)的 json 响应.它适用于除 IE 之外的所有浏览器.

I am trying to upload a file and return a json response regarding properties(name, size etc) of the file. It works fine in all browsers except IE.

IE 尝试将 JSON 作为文件下载！

我有 IE10 并通过从调试器更改浏览器模式和文档模式在 IE7 到 10 上对其进行测试.

I have IE10 and testing it on IE7 to 10 by changing browser mode and document mode from the debugger.

我正在使用 asp.net mvc4，文件上传操作具有 HttpPost 属性，我正在使用 return Json(myObject);

推荐答案

您需要将 json 作为 text/html 返回，因为 IE 不知道如何处理 application/json 内容..

You will need to return the json as text/html since IE does not know what to do with application/json contents..

return Json(myObject, "text/html");

<小时>

不确定，但使用 text/x-json

return Json(myObject, "text/x-json");
