编写要在Web API MessageHandler中使用的解压缩机制

我正在尝试为Web API MessageHandler编写解压缩机制。然而,尽管做了一点研究,我似乎无法做到这一点:-(

通过以下测试,问题是可再现的:

[Test]
public void Deflate()
{
    using (var outStream = new MemoryStream())
    {
        using (var compressionStream = new DeflateStream(outStream, CompressionMode.Compress, true))
        {
            using (var original = new MemoryStream(Encoding.UTF8.GetBytes("original content")))
            {
                original.CopyTo(compressionStream);
            }
        }
        //this passes
        Assert.IsTrue(outStream.Length > 0);

        var compressedStream = outStream;
        var decompressionResultStream = compressedStream.DeflateDecompressor();

        //this fails
        Assert.IsTrue(decompressionResultStream.Length > 0);

        var output = Encoding.UTF8.GetString(decompressionResultStream.ToArray());
        Assert.AreEqual("original content", output);
    }
}

和以下解压缩处理程序

public static class DecompressionHandlers
{
    public static MemoryStream DeflateDecompressor(this Stream compressedStream)
    {
        var decompressionResultStream = new MemoryStream();
        using (var decompressionStream = new DeflateStream(compressedStream, CompressionMode.Decompress, true))
        {
            decompressionStream.CopyTo(decompressionResultStream);
            decompressionStream.Flush();
        }
        return decompressionResultStream;
    }

    public static MemoryStream GZipDecompressor(this Stream compressedStream)
    {
        var decompressionResultStream = new MemoryStream();
        using (var decompressionStream = new GzipStream(compressedStream, CompressionMode.Decompress, true))
        {
            decompressionStream.CopyTo(decompressionResultStream);
            decompressionStream.Flush();
        }
        return decompressionResultStream;
    }
}

希望这是一个直接的ID-ten-T问题,我们非常感谢您的建议!

这将被用于Web API MessageHandler可能是一个危险的话题,但为了完整起见,包含了这一点
