golang利用http模块构建redis读写查api-Mysql Tutorial-php.cn

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

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。

先搞下golang的redis模块

cd $GOPATH/src git clone git://github.com/alphazero/Go-Redis.git redis cd redis go install

Copy after login

简单说下golang操作redis的例子

//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)); }

Copy after login

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

//xiaorui.cc package main import( "fmt" "net/http" "io/ioutil" "log" "time" "redis" ) //xiaorui.cc const AddForm = ` Name: Age: ` const setform = ` key: value: ` 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,"%s\n",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, 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 } value, e := client.Get(key); fmt.Fprintf(w, "哥们，你要查询的key %s 和value %s ",key,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
