## 一、添加依赖库、由于go受到网络、需要配置一下 ##

参考：[https://goproxy.io/zh/][https_goproxy.io_zh]

Go模块的全局代理，类似nodejs中的cnpm、npm的功能

## 二、生成二维码 ##

package main
    
    import qrcode "github.com/skip2/go-qrcode"
    import "fmt"
    
    func main() { 
    	err := qrcode.WriteFile("http://www.baidu.com", qrcode.Medium, 500, "go-qrcode.png")
    	if err != nil { 
    		fmt.Println("write error")
    	}
    }

## 三、LollipopGo ##

全球服游戏服务器框架，目前协议支持websocket、http及RPC，采用状态同步。

## 四、pravega (Streams的开源分布式存储服务) ##

介绍：Pravega是实现Streams的开源分布式存储服务。Pravega为连续和无限制的数据提供了新的存储抽象-流。Pravega流是持久的，弹性的，仅附加的，无边界的字节序列，具有良好的性能和强的一致性。
