1.?Golint

（1）安裝golint

git clone https://github.com/golang/lint.git 
cd lint/golint
go install

（2）使用方式

# 檢查單個文件
golint service.go
# 檢查當前目錄所有.go文件，不會遞歸查找
golint

（3）golint校驗規則

• 不能使用下劃線命名法，使用駝峰命名法
• 外部可見程序結構體、變量、函數都需要注釋
• 通用名詞要求大寫 iD/Id -> ID Http -> HTTP Json -> JSON Url -> URL Ip -> IP Sql -> SQL
• 包命名統一小寫不使用駝峰和下劃線
• 注釋第一個單詞要求是注釋程序主體的名稱，注釋可選不是必須的
• 外部可見程序實體不建議再加包名前綴
• if語句包含return時，后續代碼不能包含在else里面
• errors.New(fmt.Sprintf(…)) 建議寫成 fmt.Errorf(…)
• receiver名稱不能為this或self
• receiver名稱不能為this或self
• 錯誤變量命名需以 Err/err 開頭
• a+=1應該改成a++，a-=1應該改成a--

2.?Golangci-lint

（1）安裝golangci-lint

curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s -- -b $(go env GOPATH)/bin v1.41.1
golangci-lint --version

（2）使用方式

# 檢查單個文件
golangci-lint run service.go
# 指定目錄
golangci-lint run internal/
# 檢查當前目錄所有.go文件，會遞歸查找當前目錄及子目錄
golangci-lint run

（3）golangci-lint校驗規則

golangci-lint運行時會在當前目錄查找配置文件

• golangci.yml
• .golangci.yaml
• .golangci.toml
• .golangci.json

具體配置參考：

https://golangci-lint.run/usage/configuration/

（4）檢查的結果示例如下，-v參數可以看到更詳細的檢查結果

3. Go-reporter

github地址：https://github.com/qax-os/goreporter

1）安裝codestyle

# golang版本需要 >=1.6
yum -y install graphviz
go get -u github.com/360EntSecGroup-Skylar/goreporter

（2）使用方式

# 展示指令可用參數
goreporter -p [projectRelativePath] -r [reportPath] -e [exceptPackagesName] -f [json/html/text]  {-t templatePathIfHtml}
-version Version of GoReporter.
-p Must be a valid Golang project path.
-r Save the path to the report.
-e Exceptional packages (multiple separated by commas, for example: "linters/aligncheck,linters/cyclo" ).
-f report format json, html OR text.
-t Template path,if not specified, the default template will be used.
By default, the default template is used to generate reports in html format.
