只需在此处发布调查结果 - 作为聊天摘要 - 因为其他人可能会收到此错误。不要发放赏金，因为我实际上没有找到解决方案。;-)

错误本身是由于尝试访问BinaryRead,Form或在Files其他InputStream东西已经使用不同的方法访问请求实体主体流（换句话说，请求的内容）之后的结果。

这些“不同的方法”似乎包括GetBufferedInputStream和GetBufferlessInputStream。这些方法似乎（不确定）都是相互排斥的。换句话说，对于单个请求，您只能使用以下之一：

  • BinaryRead(), Form, Files, InputStream（这些将相互“合作”），
  • GetBufferedInputStream()， 或者
  • GetBufferlessInputStream()

GetBufferedInputStream 根据文档，应该与“经典”访问方法合作- 事实上，这是它与GetBufferlessInputStream. 尽管如此，在这种情况下，错误源于GetBufferedInputStream()使用，然后是InputStream.

ReadEntityBodyMode 属性及其枚举类型的文档中（不充分地）描述了不同的方法。

最近对 ASP.NET WebAPI 的提交将其读取 body 实体的方法更改为GetBufferedInputStream()之前使用request.InputStream.

这似乎与JsonValueProviderFactory.GetDeserializedObject使用“经典”InputStream属性读取实体主体的 MVC 冲突。如果我们从表面上看错误信息，GetBufferedInputStream()它已经被调用了，但是在InputStream被访问时它还没有读完，所以InputStream还没有被填充。

需要进行更多测试，但临时修复（由@KiranChalla 发现）是恢复到上述提交之前的构建。

由于这个问题（commit 9c76bb9090490541a453fcead75485ea50b88022），我们已经恢复到在 Web API 中使用 request.InputStream 。

JimmiTh 的回答正确地指出了初始发行说明和实现之间的差异。正如上面提到的后面的文档中所暗示的（虽然不是特别清楚），request.GetBufferlessInputStream()、request.GetBufferedInputStream()和request.InputStream（连同Form、Files等）是请求体的三个互斥方法使用权。

看来，与最初的发行说明相反，request.GetBufferedInputStream() 目前不可用，除非同一请求的其他调用者没有使用 InputStream、Form、Files 等中的任何一个。我也在跟进，看看是否有更好的东西可以做到这两种方法的兼容。

大卫

与产品团队交谈后的更新：调用 request.GetBufferedInputStream() 或 request.GetBufferlessInputStream() 意味着“我自己明确地处理流；带我进入禁用自动流处理的高级模式。” 但是，在仅缓冲的情况下，通常依赖于自动流处理的成员（Form、Files、InputStream 等）在缓冲流被完全读取后重新启用。

因此，正如异常消息提示的那样，在完成读取流之前触摸这些属性中的任何一个都将失败：

public ActionResult Index()
{
    Request.GetBufferedInputStream();
    var ignore = Request.InputStream;
    return View();
}

但是在读完流之后这样做会成功：

public ActionResult Index()
{
    var stream = Request.GetBufferedInputStream();
    new StreamReader(stream).ReadToEnd();
    var ignore = Request.InputStream;
    return View();
}

文档在这里不是特别清楚；我会问产品团队是否可以改进它。

我们计划在 Web API 中切换回 GetBufferedInputStream；我们将确保它与 MVC 一起使用时，相对于使用流和 MVC 执行而言，该调用发生的时间更好。

通过 Web API 上传文件时，我遇到了同样的问题。显然“超出最大请求长度”隐藏在此错误下方，因此在 web.config 中增加maxRequestLength解决了我的情况。

今天我了解到，如果您使用 WebApi 并且您的流是 aSystem.Net.Http.StreamContent.ReadOnlyStream并且您尝试从中读取 0 个字节 (stream.Read(buffer, 0, 0))，它将抛出 a System.InvalidOperationException，当被 try/catch 捕获时会显示为异常消息“在 HttpRequest.GetBufferedInputStream 的调用者填充内部存储之前访问了 BinaryRead、Form、Files 或 InputStream。”

我意识到这似乎很愚蠢，但是您可以在内存流或文件流上执行相同的操作，并且不会引发异常，在我的情况下，它来自 MsgPackCli，希望这可以节省 4 小时。
