使用go-github打印出存放庫版本

Question

我對Go非常陌生，並且在使用go-github api打印出給定回購的所有版本時遇到問題。

我在這裏調整我的代碼從example in the project。

這是我到目前爲止的代碼。

package main 

import (
    "fmt" 
    "github.com/google/go-github/github" 
    "golang.org/x/oauth2" 
) 

func main() { 

// authentication 
ts := oauth2.StaticTokenSource(&oauth2.Token{AccessToken: "XXX"}) 
tc := oauth2.NewClient(oauth2.NoContext, ts) 

client := github.NewClient(tc) 

// list all releases for single repo 
fmt.Println("Releases for repo") 
opt := &github.ListOptions{Page: 2, PerPage: 10} 
releases, _, err := client.Repositories.ListReleases("hashicorp", "terraform", opt) 

if err != nil { 
    fmt.Printf("error: %v\n", err) 
} else { 
    for _, release := range releases { 
     fmt.Printf("%v\n", release) 
    } 
} 

這工作和運行好（至少沒有錯誤），但是當我運行它，代碼不會返回任何東西。我有一種感覺，我錯過了一些簡單的東西，但我一直在抓我的頭。

從GitHub documentation on the list releases API：

這將返回發佈的名單，其中不包括尚未與發佈相關的規則的Git標籤。要獲取Git標籤列表，請使用Repository Tags API。

由於您指定的存儲庫僅包含標籤而不包含任何版本，因此不會返回任何內容。

更改ListReleases到ListTags產生類似下面的輸出：
