Functions

func GetClientIP

func GetClientIP(c *fiber.Ctx) string

GetClientIP 获取客户端 IP 1. 上下文存储中获取 2. 下游代理头信息中获取 3. TCP 协议 RemoteIP() immutable

func ProxyHandler

func ProxyHandler(backendServers []string, timeout time.Duration, backendHost string) fiber.Handler

ProxyHandler 请求代理

示例:

backendHost := "1.2.3.4:555"
backendServers := []string{"http://1.2.3.4:555"}
proxyHandler := ProxyHandler(backendServers, 1*time.Second, backendHost)
app.Use("/test/ff", proxyHandler)
6.6.6.6 请求: http://localhost:666/test/ff -> http://1.2.3.4:555/test/ff
在 1.2.3.4 服务中 GetClientIP(c) 能获取到真实客户端请求IP: 6.6.6.6

func SetClientIP

func SetClientIP(c *fiber.Ctx)

SetClientIP 首个代理加密客户端 IP, 中间代理透传 当前来访为内网 IP 会跳过设置 immutable
