Why doesn't my Go program use the Socket library correctly?

In the process of using Go language for Socket programming, you may encounter some problems, such as connection failure, connection timeout, inability to read data, etc. These problems may arise from the following aspects.

1. Understanding the principle of Socket

Socket is a stream-based communication protocol that uses the TCP/IP protocol for data transmission on the network. When using Socket for programming, you need to understand the basic principles of Socket, such as IP address, port number, connection, monitoring, data transmission and other concepts. If you don't understand these concepts, it may cause problems such as connection failure.

2. Listening or binding port error

When using Socket for programming, the Socket needs to be monitored or bound to the port. If the listening or bound port conflicts with other programs, the connection will fail. When listening on a port, be sure to pay attention to whether the port is occupied by other programs.

3. Connection timeout or error

Connection is an important step in Socket communication. If the connection times out or has a connection error, it may prevent the program from functioning properly. When connecting, you need to make sure the destination IP and port are correct, and check for any restrictions that may be caused by firewalls or routers.

4. Incorrect data transmission

When transmitting data, you need to ensure that the data type, data size, data format, data encoding, etc. sent and received are consistent. . If the data is transferred incorrectly, it may result in failure to read the data or errors in parsing the data.

5. Exceptions are not handled correctly

Exceptions may occur at any stage of the Socket application, such as connection failure, read and write timeout, etc. These exceptions need to be handled correctly, otherwise the program may crash or other errors may occur.

6. Not using the latest version

The Socket library of Go language will be updated and improved in every version. If you are using an older version of the Socket library, there is a high chance that there are some bugs and issues. Therefore, it is recommended to use the latest version of the Socket library.

In short, when using Go language for Socket programming, you need to have an in-depth understanding of the basic principles of Socket and strictly follow the rules and operating procedures of Socket programming. Only in this way can the normal operation of the program be ensured and Socket communication can be completed quickly and efficiently.
