Using FiscoBcos’ Go-SDK [1: Configure the go environment]

Environment: ubuntu 20
go: 1.17

Preface

I have told an article before FiscoBcos uses Go to call the contract, but it only involves using go-sdk to call the HelloWorld contract. Now consider a detailed use of go-sdk series.

Download golang compressed package

The version I am using is1.17, you can go to golang official website to download the go compressed package
Use the corresponding package according to your own Linux system, I use go1.17.13.linux-amd64.tar.gz
Insert image description here

After downloading, use remote connection tools such as winscp or mobaxtem to transfer the compressed package to the Linux machine
My personal habit is to transfer it to /usr/local

root@192-168-19-137:/usr/local#

Then use the decompression command to decompress to the current directory

tar -zxvf go1.17.13.linux-amd64.tar.gz

Then rename it

mv go1.17.13.linux-amd64 go

Configure environment variables

edit /etc/profiletext

vim /etc/profile

Add the go environment variable code at the end

export GOROOT=/usr/local/go  # go的路径
export GOPATH=/usr/project/gowarehouse:/usr/project/goproject # go的项目路径，可以配置多个，并用 ：进行分隔 ，推荐第一个项目目录作为go的第三方包存放仓库
export GOBIN=/usr/project/gowarehouse/bin 
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin:$GOBIN

Press :wq to save

Use this command to make environment variables take effect

source /etc/profile

Check if successful

go version

root@192-168-19-137:/usr/local# go version
go version go1.17.13 linux/amd64

Configure other necessary environments using go-sdk

Create a good project path

mkdir  -p /usr/project/gowarehouse
mkdir  -p /usr/project/goproject
mkdir  -p /usr/project/gowarehouse/src
mkdir  -p /usr/project/gowarehouse/bin
mkdir  -p /usr/project/gowarehouse/pkg

Modification of go env

go env -w GO111MODULE="on"  # 当modules 功能启用时，依赖包的存放位置变更为$GOPATH/pkg，允许同一个package多个版本并存，且多个项目可以共享缓存的module 
go env -w GOPROXY="https://goproxy.cn,direct"  # 代理地址

Usego env command to check whether the modification is successful

test

In the/usr/project/goproject directory
pull the go-sdk project for testing

git clone https://gitee.com/FISCO-BCOS/go-sdk.git

Enter go-sdk

cd go-sdk

and then use

go mod tidy

Whether relevant dependencies can be introduced into the project during testing
If no error is reported, it means the environment configuration is normal

Conclusion

This article is about configuring the go environment. After configuration, you can use the related functions of go-sdk.
