Overview

Example

This example create several reverse proxy to show how to use proxy middleware. We proxy three path to `api.bilibili.com` and return response without any changes.

package main

import (
	"go-common/library/net/http/blademaster"
	"go-common/library/net/http/blademaster/middleware/proxy"
)

func main() {
	proxies := map[string]string{
		"/index":        "http://api.bilibili.com/html/index",
		"/ping":         "http://api.bilibili.com/api/ping",
		"/api/versions": "http://api.bilibili.com/api/web/versions",
	}

	engine := blademaster.Default()
	for path, ep := range proxies {
		engine.GET(path, proxy.NewAlways(ep))
	}
	engine.Run(":18080")
}

Example

This example create several reverse proxy to show how to use jd proxy middleware. The request will be proxied to destination only when request is from specified datacenter.

package main

import (
	"go-common/library/net/http/blademaster"
	"go-common/library/net/http/blademaster/middleware/proxy"
)

func main() {
	proxies := map[string]string{
		"/index":        "http://api.bilibili.com/html/index",
		"/ping":         "http://api.bilibili.com/api/ping",
		"/api/versions": "http://api.bilibili.com/api/web/versions",
	}

	engine := blademaster.Default()
	// proxy to specified destination
	for path, ep := range proxies {
		engine.GET(path, proxy.NewZoneProxy("sh004", ep), func(ctx *blademaster.Context) {
			ctx.String(200, "Origin")
		})
	}
	// proxy with request path
	ug := engine.Group("/update", proxy.NewZoneProxy("sh004", "http://sh001-api.bilibili.com"))
	ug.POST("/name", func(ctx *blademaster.Context) {
		ctx.String(500, "Should not be accessed")
	})
	ug.POST("/sign", func(ctx *blademaster.Context) {
		ctx.String(500, "Should not be accessed")
	})
	engine.Run(":18080")
}
