c# - System.Net.ProtocolViolationException :Bytes to be written to the stream exceed the Content-Length bytes size specified

Question

我用HttpListener写web server代码，但是经常出现这样的异常

"System.Net.ProtocolViolationException:Bytes to be written to the stream exceed the Content-Length bytes size specified".

示例代码:

context.Response.Output = System.Text.Encoding.UTF8.GetBytes("xxx");
if (context.Response.Output != null && context.Response.Output.Length > 0)
{
    context.Response.ContentLength64 = context.Response.Output.Length;
    using (var stream = context.Response.OutputStream)
    {
        stream.Write(context.Response.Output, 0, context.Response.Output.Length);
    }
}

这种异常不是每次请求都会发生。谁能告诉我怎么解决。谢谢!

您似乎遇到了与以下问题相同的问题。您需要检查 HttpMethod 是否为 HEAD 请求；在这种情况下，您无法将字节写入 OutputStream 并且尝试这样做会引发您遇到的异常。
