Package netKit
PS: Golang对于host的定义 不同于 js.
e.g. "127.0.0.1:8888" host in Golang: "127.0.0.1" host in js: "127.0.0.1:8888"

Constants ¶
const ( DefaultHttpPort = 80 DefaultHttpsPort = 443 // MaxPort 65535 == 0xFFFF MaxPort = 0xFFFF )
Variables ¶
var (
DialTimeout func(network, address string, timeout time.Duration) (net.Conn, error) = net.DialTimeout
)
var JoinHostPort func(host, port string) string = net.JoinHostPort
JoinHostPort
e.g.
("127.0.0.1", "80") => "127.0.0.1:80" ("", "8888") => ":8888"
Functions ¶
func AssertValidPort ¶ added in v2.1.18
func IsLocalPortAvailable ¶ added in v2.1.18
IsLocalPortAvailable 本地端口是否可用(即未被占用)? Deprecated: 某些绑定非127.0.0.1的端口无法被检测到.
PS: 会优先判断端口是否有效(valid).
参考: Java,hutool中的NetUtil.isUsableLocalPort() golang端口占用检测的使用 https://wenku.baidu.com/view/25716f5b01768e9951e79b89680203d8ce2f6af5.html
func IsValidPort ¶
func IsValidPort(obj interface{}) bool
IsValidPort
参考: (1) Java,hutool中的NetUtil.isValidPort() (2) Linux端口分配: https://blog.csdn.net/zh2508/article/details/104888743
0 不使用 1–1023 系统保留,只能由root用户使用 1024—4999 由客户端程序自由分配 5000—65535 由服务器端程序自由分配(65535 = 2 ^ 16 - 1)
@param obj (1) 支持的类型: reflect.Value、int、uint、string...
(2) 可以为nil
func JoinHostnameAndPort ¶
JoinHostnameAndPort
e.g.
fmt.Println(netKit.JoinHostnameAndPort("127.0.0.1", 80)) // 127.0.0.1:80 fmt.Println(netKit.JoinHostnameAndPort("", 8888)) // :8888
Types ¶
type Address ¶
type Address struct { // Hostname 包括ip Hostname string `json:"hostname" yaml:"hostname"` Port int `json:"port" yaml:"port"` }
func ParseToAddress ¶
ParseToAddress
e.g.
("https://127.0.0.1") => "127.0.0.1:443", nil ("http://127.0.0.1:8888") => "127.0.0.1:8888", nil ("https://blog.csdn.net/weixin_52428496/article/details/110159938") => "blog.csdn.net:443", nil
