go mod 与 v2 预发布版本冲突

Question

我正在开发 hap 包的版本 2，它是一个 HTTP API 框架。版本 2 还没有准备好，最新版本 ls

v2.0.0-alpha.2

，如下所示：

* 9319436 - bug fix, refined action error output (HEAD -> master, tag: v2.0.0-alpha.2, origin/master, origin/HEAD) (16 hours ago) <xrfang>
* 2b1046a - various improvements (20 hours ago) <xrfang>
* 464dcb7 - example: added source IP control and global logging (tag: v2.0.0-alpha.1) (2 days ago) <xrfang>
* 94d6607 - reversed finalizer execution order (2 days ago) <xrfang>
* 7604144 - added global actions and finalizers (2 days ago) <xrfang>
... ...

整个repo的目录结构为：

.
├── example
├── go.mod
├── LICENSE
├── README.md
└── v2
    ├── api
    ├── arg
    ├── example
    ├── go.mod
    ├── handler
    └── param

根目录下的

go.mod

是：

module go.xrfang.cn/hap

go 1.17

而

v2/go.mod

看起来像：

module go.xrfang.cn/hap/v2

go 1.22.1

现在的问题是go无法获取v2预发布，

go mod tidy

在一个使用

hap/v2

的项目下：

go: downloading go.xrfang.cn/hap/v2 v2.0.0-alpha.2
go: usermgr imports
        go.xrfang.cn/hap/v2: go.mod has non-.../v2 module path "go.xrfang.cn/hap" at revision v2.0.0-alpha.2
go: usermgr imports
        go.xrfang.cn/hap/v2/api: go.mod has non-.../v2 module path "go.xrfang.cn/hap" at revision v2.0.0-alpha.2
go: usermgr imports
... ...

使用

go get

：

$ GOPROXY=direct go get -u -v -x go.xrfang.cn/hap/[email protected]
# get https://go.xrfang.cn/hap/v2?go-get=1

Answer 1

在 go-nuts 论坛的帮助下发现并解决了问题。问题是我自己的 go-get Facade 返回了不正确的元标记。它回来了

<meta name="go-import" content="go.xrfang.cn/hap/v2 git https://e.coding.net/xrfang/go/hap.git">

正确的标签应该是：

<meta name="go-import" content="go.xrfang.cn/hap git https://e.coding.net/xrfang/go/hap.git">

因为

/v2

不是这个存储库的根目录。
