【问题描述】：

我有一个正常工作的 curl 命令。

curl \
    -H "Authorization: token some-token" \
    -H "Content-Type: video/mp4" \
    --data-binary some-video.mp4 \
    "https://somewhere.com/upload-handler"

这是我认为 .NET Core 的 HttpClient 中的等价物。

using (var stream = File.OpenRead("some-video.mp4"))
using (var httpClient = new HttpClient())
{
    httpClient.DefaultRequestHeaders.Add("Authorization", "token some-token");

    var streamContent = new StreamContent(stream);
    streamContent.Headers.ContentType = new MediaTypeHeaderValue("video/mp4");

    var message = await httpClient.PostAsync(
        $"https://somewhere.com/upload-handler",
        streamContent);
    message.EnsureSuccessStatusCode();
}

但是，在运行 .NET 示例时，我得到了这个。

Unhandled exception: System.Net.Http.HttpRequestException: Error while copying content to a stream.

我正在运行 .NET Core 3.1、Ubuntu 18.04。

以防万一，我正在尝试通过 API 将二进制文件上传到 GitHub 版本：https://developer.github.com/v3/repos/releases/#upload-a-release-asset

编辑：我通过 Charles 发送了 HttpClient 代码以查看发生了什么，然后它起作用了... :( 所以，我无法判断出了什么问题. 酷。

【问题讨论】：

你发现问题出在哪里了吗？我相信 .NET Core 在发送长流时存在随机问题。
我在写入 Azure 缓存时也遇到了同样的问题。你解决了这个问题吗？

【解决方案1】：

我在尝试使用来自 AWS Code Build 中的 ubuntu 构建代理的 dotnet nuget push 命令将 nuget 包推送到 GitHub 包注册表时遇到类似错误。我推送了多个 nuget 包，而这个错误只是偶尔（90% 的时间）发生在最大的包（~5MB）上。

error: Error while copying content to a stream.
error:   Unable to read data from the transport connection: Broken pipe.
error:   Broken pipe

我正在使用 dotnet sdk 2.2。

我在任何地方都找不到有关此错误的任何有用信息，但这篇文章让我有了一些思考https://support.sonatype.com/hc/en-us/articles/360000228868-Artifact-uploads-fail-with-broken-pipe-errors
