Golang1.13.x 解决go get 无法下载问题

安装golang github.com/hyperledger/fabric-contract-api-go依赖包的时候，长时间无响应，最后报如下错误：

go: github.com/hyperledger/fabric-contract-api-go@v1.0.0: Get https://proxy.golang.org/github.com/hyperledger/fabric-contract-api-go/@v/v1.0.0.mod: dial tcp 172.217.27.145:443: i/o timeout

解决办法

使用七牛云 go module 镜像

golang1.13.x 可以直接执行：

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

然后再次使用 go get 下载 gin 依赖就可以了。
