git clone git://github.com/alphazero/go-redis.git Redis

Installation of Redis can be performed in any directory

After installation, generate a pkg directory under the C:\go\code directory and generate the REDIS.A in the directory.

You can generate a catalog file under C:\go\code\src xn

The structure is as follows

The file contents are as follows

Xn.go

Package xn

Import (

"FMT"

)

func Helloworld () {

Fmt. Println (" helloeorld function within the xn package ")

}

func xx () {

Fmt. Println (" xx function in xn package ")

}

Neng.go files are as follows

Package Neng

Import (

"FMT"

)

func Helloworld () {

Fmt. Println (" helloeorld function within the Xn.neng package ")

}

Installing XN third-party libraries

Go install xn

Examples of Use

Package Main

"Xn/neng"

)

func Main () {

b:= 2 //:= This notation can only be used inside a function

Fmt. Println ("Hello,world, Hello, World ")

Xn. Helloworld ()

Neng. Helloworld ()

//defaultspec () Create a connection specification

Spec: = Redis. Defaultspec (). Host ("127.0.0.1"). Port (6666). Password ("test123");

// Create a new syncclient , and connect to Redis on the server using the , Specify Connectionspec interface.

Client, Err: = Redis. Newsynchclientwithspec (spec);

if err! =Nil {

Log. Println (" connection Server failed >", Err);

return

}

Dbkey: = "GAME:TEST:info";

Value, Err: = client. Get (Dbkey);

if err!= nil {

Log. PRINTLN ("error on Get", err);

return

}

//

if value = =Nil {

Value: =[]byte("sina.com!");

Client. Set (Dbkey, value);

Fmt. Printf (" Insert data >%s \ n", value)

} Else {

Fmt. Printf (" received data >%s \ n", value);

//return;

}
