如何更改httppostedfilebase的内容类型？ [英] How to change the content type of httppostedfilebase?

问题描述

我正在使用HttpPostedFileBase使用ASP.NET MVC上传文件。我需要将此发布到API调用，我收到错误StatusCode：403，Reason Phrase：'Forbidden'，Version：1.1，Content：System.Net.Http.StreamContent。这是因为我将文件内容作为application / octet-stream传递，其中API调用希望内容类型为application / vnd.qlik.sense.app。互联网上的很多帖子都说HttpPostedFileBase是只读的，我们无法更改内容类型。任何人都可以告诉我们如何更改HttpPostedFileBase的内容类型。这可能吗？



我尝试过：

I am using HttpPostedFileBase to upload a file using ASP.NET MVC. I need to post this to a API call and i am getting a error "StatusCode: 403, Reason Phrase: 'Forbidden', Version: 1.1, Content: System.Net.Http.StreamContent". This is because i am passing file content as "application/octet-stream", where as API call wants the content type as "application/vnd.qlik.sense.app". Many posts in internet says that HttpPostedFileBase is a read only and we cannot change the content type. Can anybody let me know how we can change the content type of HttpPostedFileBase. Is this possible??

推荐答案

您是否尝试过添加 application / vnd。 qlik.sense.app 作为web.config文件中的mime类型？这样的事情：

Have you tried adding application/vnd.qlik.sense.app as a mime type in your web.config file? Something like this:

<System.webServer>
    <staticContent>
        <remove fileExtension=".sense.app" />
        <mimeMap fileExtension=".sense.app" mimeType="qlik_sense_app" />
    </staticContent>
</system.webServer>

您可能需要从 fileExtension 属性，因为如果IIS可以使用该格式，我现在还没有。

You may have to remove ".sense" from the fileExtension attribute, because I don't now right off hand if that format is usable by IIS.
