Answer 1

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.不要分发赏金,因为我实际上没有找到解决方案.;-)

错误本身就是试图访问的结果BinaryRead,Form,Files或InputStream以后别的东西已经访问请求实体正文流(换句话说,请求的内容)使用不同的方法.

这些"不同的方法"似乎包括GetBufferedInputStream和GetBufferlessInputStream.这些方法看起来(不确定)都是互斥的.换句话说,对于单个请求,您只能使用以下之一:

• BinaryRead(),Form,Files,InputStream(这些都将"合作"与对方),
• GetBufferedInputStream(), 要么
• GetBufferlessInputStream()

GetBufferedInputStream 应该与"经典"访问方法配合,根据文档 - 事实上,这是它唯一的区别GetBufferlessInputStream.尽管如此,在这种情况下,错误源于GetBufferedInputStream()使用,其次是InputStream.

的不同方法(不足)的文档中描述ReadEntityBodyMode属性和它的枚举类型.

一个最近提交给ASP.NET的WebAPI改变读取体实体的方法,GetBufferedInputStream()它使用前在那里request.InputStream.

这似乎与JsonValueProviderFactory.GetDeserializedObject使用"经典" InputStream属性来读取实体主体的MVC相冲突.如果我们在面值处获取错误消息,GetBufferedInputStream()已经被调用,但是在InputStream访问时没有读取,所以InputStream还没有被填充.

需要做更多测试,但临时修复(由@KiranChalla找到)是在上述提交之前恢复为构建.

Answer 2

由于此问题,我们已恢复使用Web API中的request.InputStream(commit 9c76bb9090490541a453fcead75485ea50b88022).

JimmiTh的回答正确地指出了初始发行说明与实现之间的差异.正如上面提到的后面文档所暗示的那样(虽然不是特别清楚),request.GetBufferlessInputStream(),request.GetBufferedInputStream()和request.InputStream(以及Form,Files等)是三个互斥的请求体方法访问.

看起来,与初始发行说明相反,request.GetBufferedInputStream()当前不可用,除非同一请求的其他调用者不使用任何InputStream,Form,Files等.我也在跟进,看看是否有更好的东西可以做到这两种方法之间的兼容性.

与产品团队交谈后的更新:调用request.GetBufferedInputStream()或request.GetBufferlessInputStream()表示"我自己正在处理流;请将我带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)在完全读取缓冲流之后重新启用.

因此,正如异常消息提示,在完成读取流之前触摸任何这些属性将失败:

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

但是在完成读取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();
}

这里的文件不是特别清楚; 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; 我们只是确保它在MVC中发挥的作用相对于消耗流和MVC执行而言.

Answer 3

通过Web API上传文件时遇到了同样的问题.显然"超出最大请求长度"隐藏在此错误之下,因此在我的情况下增加web.config中的maxRequestLength解决了它.

Answer 4

今天，我了解到，如果您使用的是WebApi，并且您的流是a，System.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，当它被try / catch捕获时显示异常，并显示消息“在HttpRequest.GetBufferedInputStream的调用者填充内部存储之前，已访问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，就我而言，它来自MsgPackCli，希望这可以为某人节省4个小时。
