通过导入父目录,用golang导入子包?
我有这个main.go文件:
I have this main.go file:
package main
import "one/entities/bar"
func main(){
}
我有这个目录结构:
当我使用以下项目构建项目时:
When I build my project with:
go install main
我收到此编译错误:
src/main/main.go:3:8:没有Go文件 /home/oleg/codes/oresoftware/oredoc/test/builds/go/src/one/entities/bar
src/main/main.go:3:8: no Go files in /home/oleg/codes/oresoftware/oredoc/test/builds/go/src/one/entities/bar
该错误是有道理的.有什么方法可以从one/entities/bar
目录中导入所有子包?
that error makes sense. Is there some way to import all the subpackages from within the one/entities/bar
directory?
类似这样的东西:
package main
import bar "one/entities/bar/*"
func main(){
}
(使用某种*语法并在bar名称空间中导入所有子包).
(using some sort of * syntax and importing all subpackages in the bar namespace).
最终,我正在尝试执行以下操作:
package main
import (
"log"
"one/entities/bar"
)
func main(){
v := bar.Get.Basic.Req.Headers{}
log.Fatal(v)
}
You can't do such thing, according to the specs of import
:
The import names an identifier (PackageName) to be used for access and an
ImportPath that specifies the package to be imported.
ImportDecl = "import" ( ImportSpec | "(" { ImportSpec ";" } ")" ) .
ImportSpec = [ "." | PackageName ] ImportPath .
ImportPath = string_lit .
导入语法需要包名称或包路径.因此,没有通配符导入.
The import syntax requires a package name or path of a package. So no wildcard import.
此声明将阐明原因;
The PackageName is used in qualified identifiers to access exported
identifiers of the package within the importing source file.
您必须指定要引用的元素在哪个包中存在.例如bar.Get.Basic.Req.Headers
.如果没有显式导入,则无法确定.
You must specify in which package the element you are referring to exists. e.g, bar.Get.Basic.Req.Headers
. This can't be determined without an explicit import.
