如何将zip文件发送到ASP.NET WebApi

Question

我想知道如何将zip文件发送到WebApi控制器,反之亦然.问题是我的WebApi使用json传输数据.zip文件不可序列化,也可以是流.字符串可以序列化.但是必须有另一种解决方案,而不是将zip转换为字符串而不是发送字符串.这听起来不对.

知道怎么做的吗？

如果您的API方法需要,HttpRequestMessage那么您可以从中提取流:

public HttpResponseMessage Put(HttpRequestMessage request)
{
    var stream = GetStreamFromUploadedFile(request);

    // do something with the stream, then return something
}

private static Stream GetStreamFromUploadedFile(HttpRequestMessage request)
{
    // Awaiting these tasks in the usual manner was deadlocking the thread for some reason.
    // So for now we're invoking a Task and explicitly creating a new thread.
    // See here: http://stackoverflow.com/q/15201255/328193
    IEnumerable<HttpContent> parts = null;
    Task.Factory
        .StartNew(() => parts = request.Content.ReadAsMultipartAsync().Result.Contents,
                        CancellationToken.None,
                        TaskCreationOptions.LongRunning,
                        TaskScheduler.Default)
        .Wait();

    Stream stream = null;
    Task.Factory
        .StartNew(() => stream = parts.First().ReadAsStreamAsync().Result,
                        CancellationToken.None,
                        TaskCreationOptions.LongRunning,
                        TaskScheduler.Default)
        .Wait();
    return stream;
}

当我发布HTTP表单时,这适用于我enctype="multipart/form-data".
