Static resource file packaging
The above packaging can only package go language files. If static resources or configuration files are used in the project, they will not be packaged, and an error will be reported after running the packaged file
Solution: Use go-bindata to package the configuration file into a binary go file
First install go-bindata
go get -u github.com/jteeuwen/go-bindata/... # golang
go-bindata #执行此命令验证安装成功与否
#如果命令执行失败，则
echo $GOPATH/bin #查看gopath/bin目录是否有go-bindata可执行文件
cp $GOPATH/bin/go-bindata /bin
go-bindata packages static files into go files
go-bindata -o=bindata/bindata.go -pkg=bindata conf/... crts/...
-o=bindata/bindata.go: The generated bindata.go file is packaged and placed in the bindata/ directory
-pkg=bindata: Bindata.go file generated by packaging, the package name is set to bindata
conf/... crts/...: all files in the folder to be packaged

go-bindata --help
Get static resources packaged by go-bindata in the go program
Method 1: Read the content of the static file packaged by go-bindata directly in the go program (cannot be modified in real time)
func main() {
// 获取所有资源路径和文件名称
assets := bindata.AssetNames()
for _, asset := range assets {
//获取配置文件内容，bytes中就是配置文件内容的字节数组
bytes, err := bindata.Asset(asset)
fmt.Println(bytes, err)
}
}
Method 2: Unzip the configuration file to the same folder as the static resource path, and then read the configuration file through the go program (can be modified in real time)
func main() {
// 释放资源文件
releaseResources()
// 加载配置文件(此处省略)
config.LoadConfiguration()
......
}
