Description: 局域网文件传输
为了设计统一和用户操作方便，我们希望将服务端与客户端融合在一起，形成一个程序，这样用户理解起来，更加直观一点（其实这样做也是为了方便调试，大家可以在本机上测试，自己传文件给自己）。所以，我们在程序中需要使用两个Winsock控件，一个负责监听，一个负责发送，当发送端连接成功以后，便选择一个待发送的文件（可以是任意二进制文件），接着将文件名和文件字节长度发送给接收端，接收端收到这个消息以后，将文件名和文件长度解析出来，然后通知发送端可以开始发送文件；发送端读到这个消息之后，将文件流以字节的形式发送到接收端，接收端收到后，将二进制流回写，保存成文件即可。这里要注意两点，一个是由于Winsock每次最大传输8K的内容，所以需要将文件分解，每次传输固定数目的字节流，这样发送和接收时都可以根据这个数目来判断文件传输的进程，一旦字节流数目等于文件的大小，就需要关闭相应的文件句柄；另一点是由于我只使用一个Winsock控件接收，接收文本时需要注意要将UNICODE转码，解析成可识别的信息。
-LAN file transfer to uniform design and user convenience, we hope it will end service and client together and form a process so that users understand, a more intuitive 1:00 (in fact, do so in order to facilitate debugging, you can test the machine, its own text- items for himself). Therefore, we need procedures in the use of two Winsock Control, a charge of wiretapping, a charge of this, when the transmitter connects successfully, it will be a choice to send the document (can be arbitrary binary files), will then file names and the length byte sent to the receiver, receiver- After receiving the news, file names and length analysis, and then notify the sender can begin sending documents; Send-read the news, the flow of documents in the form of bytes sent to the receiving end, the receivin Platform: |
