1. “ping: sendto: socket is not connected”错误信息的含义 当在命令行中使用ping命令尝试向某个IP地址或域名发送ICMP回显请求(Echo Request)时,如果遇到“ping: sendto: socket is not connected”的错误信息,这通常表明在尝试发送数据包之前,网络层(通常是IP层)的socket连接没有正确建立或配置。然而,需要澄...
编号10057错误（假设错误有很多种，你的计算机给它们编了号，那么这个错误的编号就是10057了），发送连接请求失败。（所谓socket通常也称作"套接字"，用于描述IP地址和端口，是一个通信链的句柄。应用程序通常通过"套接字"向网络发出请求或者应答网络请求。）goodluck ...

如果send函数copy数据成功,就返回实际copy的字节数,如果send在copy数据时出现错误,那么send就返回SOCKET_ERROR;如果send在等待协议传送数据时网络断开的话,那么send函数也返回SOCKET_ERROR。需要注意send函数把buf中的数据成功copy到s的发送缓冲的剩余空间里后它就返回了,但是此时这些数据并不一定马上被传到连接的另一端。
This function is used to write outgoing data on a connected socket. For message-oriented sockets, care must be taken not to exceed the maximum packet size of the underlying provider, which can be obtained by using getsockopt (Windows Sockets) to retrieve the value of socket option SO_MAX_...

我也遇到了这个问题，后面发现是服务端抛出了异常，建议检查服务端
