package main
import (
"context"
"github.com/cloudwego/hertz/pkg/app"
"github.com/cloudwego/hertz/pkg/app/server"
"github.com/cloudwego/hertz/pkg/protocol/consts"
)
func main() {
h := server.Default(server.WithHostPorts("127.0.0.1:8080"))
h.GET("/externalRedirect", func(ctx context.Context, c *app.RequestContext) {
c.Redirect(consts.StatusMovedPermanently, []byte("http://www.google.com/"))
})
h.GET("/internalRedirect", func(ctx context.Context, c *app.RequestContext) {
c.Redirect(consts.StatusFound, []byte("/foo"))
})
h.GET("/foo", func(ctx context.Context, c *app.RequestContext) {
c.String(consts.StatusOK, "hello, world")
})
h.Spin()
}
这段代码里写了三个 GET 请求,第一个是重定向到外部链接,第二个和第三个是重定向到内部链接。可以看到,如果不需要很复杂的处理逻辑,直接贴上地址即可,如果需要复杂的处理逻辑,可以写在重定向的目标 URI 相关的请求里,这样相对解耦了一部分纠缠在一块的逻辑,如果跳转一个 URI 就需要一个特别的处理,这样每个目标 URI 之间的处理互不影响。
要运行还是一行解决:
go run redirect/main.go
这次需要查看两个链接:http://127.0.0.1:8080/externalRedirect 和 http://127.0.0.1:8080/internalRedirect。
