使用Web API返回二进制数据

问题描述

我有以下返回字节数组的控制器方法.

I have the following controller method which returns a byte array.

    public async Task<HttpResponseMessage> Get()
    {
        var model = new byte[] { 1, 2, 3 };

        HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
        result.Content = new StreamContent(new MemoryStream(model));
        result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
        return result;
    }

我认为这是使用Web API实现此功能的较旧方法.还有更现代"的版本吗?

I think this is an older way of implementing this functionality with web api. Is there a more "modern" version?

例如，现在首选返回Task<IHttpActionResult>吗?如果是这样，从上面返回字节数组的代码是什么?

For example, is returning a Task<IHttpActionResult> the preferred way now? And if so, what would be the code to return the byte array from above?

推荐答案

正如评论所指出的.我认为没有新的方法可以做到这一点.但是，如果您想返回一个IHttpActionResult，则有一个基本方法返回一个ResponseMessageResult:

As the comment pointed out. I dont think there is a new way to do this. But if you would like to return an IHttpActionResult instead, there is a base method that returns a ResponseMessageResult:

public IHttpActionResult Get()
{
    var model = new byte[] { 1, 2, 3 };

    var result = new HttpResponseMessage(HttpStatusCode.OK)
    {
        Content = new StreamContent(new MemoryStream(model))
    };
    result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
    return ResponseMessage(result);
}
