Windows下使用go连接SAP RFC函数

主要使用的资源：

SAP的nwrfcsdk和gorfc库。

基本步骤如下：

Windows下使用go连接SAP RFC函数

#安装nwrfcsdk
C:\nwrfcsdk

#配置path
;C:\nwrfcsdk\lib

#配置环境变量
变量名：CGO_CFLAGS   变量值：C:\nwrfcsdk\include
变量名：CGO_LDFLAGS  变量值：C:\nwrfcsdk\lib

#安装gcc
https://sourceforge.net/projects/mingw/

#安装go saprfc库
go get github.com/stretchr/testify
go get github.com/sap/gorfc
cd $GOPATH/src/github.com/sap/gorfc/gorfc
go build
go install
