返回从控制器的二进制文件中的ASP.NET Web API [英] Returning binary file from controller in ASP.NET Web API

问题描述

我正在使用ASP.NET MVC的新的WebAPI的Web服务，这将有助于了二进制文件，大多是的.cab 和 .EXE 文件。

I'm working on a web service using ASP.NET MVC's new WebAPI that will serve up binary files, mostly .cab and .exe files.

下面的控制器方法似乎工作，这意味着它返回一个文件，但它的设置内容类型应用程序/ JSON ：

The following controller method seems to work, meaning that it returns a file, but it's setting the content type to application/json:

public HttpResponseMessage<Stream> Post(string version, string environment, string filetype)
{
    var path = @"C:\Temp\test.exe";
    var stream = new FileStream(path, FileMode.Open);
    return new HttpResponseMessage<Stream>(stream, new MediaTypeHeaderValue("application/octet-stream"));
}

有没有更好的方法来做到这一点？

Is there a better way to do this?

推荐答案

尝试使用简单的的Htt presponseMessage ，以 StreamContent 里面，它应该很好地工作。

Try using a simple HttpResponseMessage, with a StreamContent inside, which should work fine.

public HttpResponseMessage Post(string version, string environment,
    string filetype)
{
    var path = @"C:\Temp\test.exe";
    HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
    var stream = new FileStream(path, FileMode.Open);
    result.Content = new StreamContent(stream);
    result.Content.Headers.ContentType = 
        new MediaTypeHeaderValue("application/octet-stream");
    return result;
}
