使用golang的http模块构建redis读写查api
前沿: 这两天试着用golang做一些高性能的api,不想把压力到聚合在平台的接口上。平台因为要做很多耗时间的操作,uwsgi下会出现少许错误,找了一圈不知道如何解决该问题。 暂时先绕道而行,先拿简单的接口来做测试,慢慢的把复杂的操作也迁移到golang上。 话说以前高性能的接口,我用的最多的方案还是nginx lua的组合,超强,大家可以看看我以前写的nginx lua的文章,各方面没得说。只是这段时间正在看golang 的,就试着用golang实现redis的api,先来个简单的试试手。 里面引用的是golang自带的http模块,redis是自己down的。 golang redis的配置方法: cd $GOPATH/src git clone git://github.com/alphazero/Go-Redis.git redis cd redis go install 先简单说下,golang对于redis的操作方法: //xiaorui.cc package main import ( "os"; "bufio"; "log"; "fmt"; "redis"; ) /* hello world,redis style. */ func main () { // create the client. Here we are using a synchronous client. // Using the default ConnectionSpec,we are specifying the client to connect // to db 13 (e.g. SELECT 13),and a password of go-redis (e.g. AUTH go-redis) spec := redis.DefaultSpec().Db(13).Password("go-redis"); client,e := redis.NewSynchClientWithSpec (spec); if e != nil { log.Println ("failed to create the client",e); return } key := "examples/hello/user.name"; value,e := client.Get(key); if e!= nil { log.Println ("error on Get",e); return } if value == nil { fmt.Printf("nHello,don't believe we've met before!nYour name? "); reader:= bufio.NewReader(os.Stdin); user,_ := reader.ReadString(byte('n')); if len(user) > 1 { user = user[0:len(user)-1]; value = []byte(user); client.Set(key,value); } else { fmt.Printf ("vafanculo!n"); return; } } fmt.Printf ("Hey,ciao %s!n",fmt.Sprintf("%s",value)); } 我写的实例,大家看懂了后,完全可以做更多的扩展。 其实golang自带的http很有mvc的感觉,三者做了一些分离,很像python里面的web.py tornado。。。 测试结果: 服务端的启动 客户端的测试 原文:http://www.52php.cn/article/p-wqmxalhu-ng.html //xiaorui.cc package main import( "fmt" "net/http" "io/ioutil" "log" "time" "redis" ) //xiaorui.cc const AddForm = ` <html><body> <form method="POST" action="/add"> Name: <input type="text" name="name"> Age: <input type="text" name="age"> <input type="submit" value="Add"> </form> </body></html> ` const setform = ` <html><body> <form method="POST" action="/set"> key: <input type="text" name="key"> value: <input type="text" name="value"> <input type="submit" value="set"> </form> </body></html> ` func Handler( w http.ResponseWriter,r *http.Request ){ path := r.URL.Path[1:] if path == "favicon.ico" { http.NotFound(w,r) return } if path == ""{ path = "index.html" } contents,err:= ioutil.ReadFile( path ) if err !=nil{ fmt.Fprintf( w,"404" ) return } fmt.Fprintf( w,"%sn",contents ) } func Add( w http.ResponseWriter,r *http.Request ){ name := r.FormValue("name") age := r.FormValue("age") if name == "" || age == "" { fmt.Fprint(w,AddForm) return } fmt.Fprintf(w,"Save : Your name is %s,You age is %s",name,age) } func redisset( w http.ResponseWriter,r *http.Request ){ key := r.FormValue("key") value := r.FormValue("value") if key == "" || value == "" { fmt.Fprint(w,setform) return } spec := redis.DefaultSpec().Db(0).Password(""); client,e := redis.NewSynchClientWithSpec (spec); if e != nil { log.Println ("服务器连接有异常",e); return } inva := []byte(value) client.Set(key,inva); fmt.Fprintf(w,"哥们,你输入的key %s 和value %s 已经插入到redis里面了",key,key) } func redisget( w http.ResponseWriter,r *http.Request ){ key := r.FormValue("key") if key == "" { fmt.Fprint(w,e); return } value,e := client.Get(key); fmt.Fprintf(w,"哥们,你要查询的key %s 和value %s ",value) } func valueget(w http.ResponseWriter,r *http.Request) { params := r.URL.Query() user := params.Get("user") fmt.Fprintf(w,"you are get user %s",user) } func main(){ http.HandleFunc( "/",Handler) http.HandleFunc( "/add",Add) http.HandleFunc( "/redisset",redisset) http.HandleFunc( "/redisget",redisget) http.HandleFunc( "/valueget",valueget) s := &http.Server{ Addr: ":80",ReadTimeout: 30 * time.Second,WriteTimeout: 30 * time.Second,MaxHeaderBytes: 1 << 20,} log.Fatal(s.ListenAndServe()) } 对于go的基础教程,我也写过其他的文章,大家可以参考下。 关于Golang语言的web编程的实例及常见问题 http://www.52php.cn/article/p-cvbhvbgk-ng.html 关于Go语言在服务端做Restful接口和socket通信 http://www.52php.cn/article/p-usbcgzmu-ng.html (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
