.Net SslStream写入/读取问题 [英] .Net SslStream Write/Read issue

问题描述

当我阅读一个.Net SSLStream时，似乎无法一次阅读所有内容. read方法始终仅获取第一个字节.无论数据或缓冲区大小如何，我都需要循环获取剩余的数据.

When I read an a .Net SSLStream, I can't seem to read it all in one go. The read method always gets the first byte only. I need to loop to get the remaining data no matter the data or buffer size.

示例:

客户

var message = new byte[]{1,2,3,4,5};
   sslStream.Write(messsage);
   sslStream.Flush();

服务器

byte[] buffer = new byte[4000];
bytes = sslStream.Read(buffer, 0, buffer.Length);

我做错什么了吗?为什么在第一次读取时只读取一个字节?

Am I doing something wrong ? Why is it reading only one byte on the first read ?

推荐答案

流API不会保证您每次读取都返回特定数量的字节.您可以读取从1开始的任意数量的字节.即使我们请求更大的块，甚至发送了更大的块，我们的代码也必须能够按字节接收数据.

Streaming APIs do not promise you to return a specific number of bytes per read. You can read any number of bytes starting from 1. YOur code must be able to deal with receiving the data byte-wise even if you asked for bigger chunks and even if you sent bigger chunks.

对此的最佳解决方法是不使用套接字.使用更高级别的API，例如WCF，SignalR，HTTP，...

The best fix for this is to not use sockets. Use a higher level API such as WCF, SignalR, HTTP, ...

如果您坚持要使用BinaryReader/Writer来发送数据.这很容易.

If you insist you probably should use BinaryReader/Writer to send your data. That makes it quite easy.

如果您不想要其中的任何一个，则需要循环读取，直到收到所需的字节数为止.

If you don't want any of that you need to read in a loop until you have received as many bytes as you need.
