问题描述
当我在go应用程序中导入软件包时(使用带有golang插件的模块和vscode):
When I import a package in a go application (using modules and vscode with golang plugin):
import (
cors "goa.design/plugins/cors/dsl"
)
go自动检索软件包.怎么知道从哪里得到它呢?我认为它只是从github.com提取资源，但是该项目的存储库名称中是 https://github.com/goadesign/goa 否...如果我将导入更改为:
go automatically retrieves the package.How does go know where to get it from?I figured it simply pulls the sources from github.com, but the repository for this project is at https://github.com/goadesign/goa no . in the name.And if I change the import to:
import (
cors "goa.design/plugins/v3/cors/dsl"
)
它检索 v3 包.我很乐意RTFM，但不确定我需要阅读哪个FM.
It retrieves the v3 package. I would gladly RTFM, but not sure which FM I need to read.
顺便说一句:这是我第二天去 go ，所以对我来说这是神奇的.
Btw: this is my second day on go so this is magic to me.
推荐答案
很简单，请检查一下:
$> curl https://goa.design/plugins/cors/dsl
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en-us">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<meta name="go-import" content="goa.design/plugins git https://github.com/goadesign/plugins">
<meta name="go-source" content="goa.design/plugins _ https://github.com/goadesign/plugins/tree/master/{/dir} https://github.com/goadesign/plugins/blob/master{/dir}/{file}#L{line}">
此处的键位于名为"go-import"的标签中.当 go get 请求 https://goa.design/ ...时，它会HTML文件，并知道必须使用git从 https://github中检索到"goa.design/....".com/goadesign/plugins .
The key here is in the tag named "go-import". When go get requests https://goa.design/..., it hits that HTML file and knows that "goa.design/...." must be retrieved using git from https://github.com/goadesign/plugins.
