Socket问题，发送的数据和接收的数据，怎么不一样啊，郁闷！！！

[ie521]

小弟在做FTP客户端，用了以一代码向FTP Server(Serv-U)发送数据:

char sendbuf[255];
AnsiString sendstr="user niangzao";
StrPCopy(sendbuf, sendstr);

int sendbuflen=StrLen(sendbuf);
cs1->Socket->SendBuf(sendbuf,255);

但在Serv-U的日志里，显示已经发了三条命令，还有乱码出现，如下：

[5] Sun 07May06 18:28:48 - (000009) Connected to 192.168.0.8 (Local address 192.168.0.8)

不知道为什么，请高手指点一二，感激不尽。

没测试过，随便写的，你试试

char sendbuf[255];
AnsiString sendstr="user niangzao";
memcpy(&sendbuf[0], sendstr.c_str(),sendstr.Length());

// int sendbuflen=StrLen(sendbuf);
cs1->Socket->SendBuf(sendbuf,sendstr.Length());

[铖邑]

int sendbuflen=StrLen(sendbuf);
cs1->Socket->SendBuf(sendbuf,sendbuflen);

[铖邑]

AnsiString sendstr="user niangzao";
cs1->Socket->SendBuf(sendstr.c_str(),sendstr.Length());

楼上的那个len是不是加上个1好一点???

[铖邑]

我想，应该要加个换行符吧
AnsiString sendstr="user niangzao\n";
cs1->Socket->SendBuf(sendstr.c_str(),sendstr.Length());

ftp命令不是已\0 结尾 而是\r\n
