connect to '202.207.160.232:3389' failed [ERROR 0 ] success

As an AI language model, I do not have the capability to connect to external servers or devices. I apologize for the inconvenience. Is there anything else I can assist you with?

connect to '127.0.0.1:3389' failed [ERROR 0] Success

This error message indicates that there was an attempt to connect to a Remote Desktop Protocol (RDP) server at the IP address 127.0.0.1 on port 3389, but the connection failed with an error code of 0, which indicates success.

There could be several reasons why the connection failed, such as:

1. The RDP server may not be running on the specified IP address and port.
2. There could be a firewall or security software blocking the connection.
3. The RDP server may not be configured to accept incoming connections from the IP address or network that the connection attempt is coming from.

To troubleshoot the issue, you can try the following:

1. Ensure that the RDP server is running and configured to accept incoming connections.
2. Check if there is a firewall or security software blocking the connection and configure it to allow the connection.
3. Verify that the IP address and port number are correct and that the RDP server is configured to accept incoming connections from that IP address or network.

改进函数var rdb *redis.Client func initClient() (err error) { rdb = redis.NewClient(&redis.Options{ Addr: "127.0.0.1:6379", Password: "123456", // 密码 DB: 0, //PoolSize: 100, // 连接池大小 }) _, err = rdb.Ping().Result() return err } func main() { if err := initClient(); err != nil { fmt.Printf("init redis client failed, err:%v\n", err) return } fmt.Println("connect redis success...") locations := []*redis.GeoLocation{ {Name: "Beijing", Longitude: 116.404, Latitude: 39.915}, {Name: "Shanghai", Longitude: 121.473, Latitude: 31.230}, {Name: "Guangzhou", Longitude: 113.264, Latitude: 23.129}, } rdb.GeoAdd("locations", locations...) //设置中心点经纬度 longitude := 118.397128 latitude := 30.916527 //设置半径和单位（单位可以是米、千米、英里等） radius := redis.GeoRadiusQuery{ Radius: 1000, Unit: "km", } //调用GeoRadius函数并获取结果 results, err := rdb.GeoRadius("locations", longitude, latitude, &radius).Result() if err != nil { fmt.Println("GeoRadius error", err) return } //遍历结果并输出 for _, result := range results { locationName := result.Name locationDist := result.Dist locationCoord := result.GeoHash fmt.Println(locationName, locationDist, locationCoord) } // 释放相关资源 defer rdb.Close() }

你的改进函数中，将 Redis 客户端对象 `rdb` 定义为全局变量，并在 `initClient()` 函数中初始化，这样可以避免频繁地创建和销毁 Redis 客户端对象，从而提高程序的运行效率。此外，你还将 Redis 连接的信息（如 Redis 服务器的地址、密码等）封装到 `redis.Options` 结构体中，并通过 `redis.NewClient()` 方法来创建 Redis 客户端对象，这样代码更加简洁和易于维护。

在 `main()` 函数中，你首先调用 `initClient()` 函数来初始化 Redis 客户端对象 `rdb`，并检查初始化是否成功。然后，你通过 `rdb.GeoAdd()` 方法向 Redis 中添加了一些位置信息。接下来，你设置了一个中心点的经纬度坐标和一个查询半径和单位，然后调用 `rdb.GeoRadius()` 方法来获取符合查询条件的位置信息，并遍历结果将位置名称、距离和 GeoHash 值输出。最后，你通过 `defer` 语句释放了相关资源，避免程序运行结束后出现资源泄漏的情况。

这样改进后的代码结构更加清晰，可读性和可维护性都得到了提高。
