如何从一个GitHub repo列表操作获取所有fork源？

Question

我想获得GitHub用户的repos的所有源代码库。我必须分两步完成。例如，首先，我可以使用https://api.github.com/users/nmap/repos获取用户nmap的所有回购。但source和parent不存在。只有当我为每个回购打电话给https://api.github.com/repos/nmap/:repo_name时，我才能得到source和parent：

我只想知道fork的来源。例如从the-tcpdump-group/libpcap了解nmap/libpcap。我想知道有没有办法从GitHub repo列表操作中获取所有fork源仅一步？

Answer 1

您可以使用GraphQL API v4获取特定用户/组织的分叉回购列表，并获取父回购名称：

{
  organization(login: "nmap") {
    repositories(first: 100, isFork: true) {
      edges {
        node {
          parent {
            nameWithOwner
          }
        }
      }
    }
  }
}

Try it in the explorer

使用go的示例：

package main

import (
    "fmt"
    "encoding/json"
    "net/http"
    "bytes"
    "io/ioutil"
)

var token string = "YOUR_ACCESS_TOKEN"

func main() {
    jsonMap := map[string]string{"query": `{
      organization(login: "nmap") {
        repositories(first: 100, isFork: true) {
          pageInfo {
            hasNextPage
            endCursor
          }
          edges {
            node {
              parent {
                nameWithOwner
              }
            }
          }
        }
      }
    }
    `}
    jsonData, _ := json.Marshal(jsonMap)

    client := &http.Client{}
    req, _ := http.NewRequest("POST", "https://api.github.com/graphql", bytes.NewBuffer(jsonData))
    req.Header.Add("Authorization",  fmt.Sprint("Token ", token))
    req.Header.Add("Content-Type", "application/json")
    resp, _ := client.Do(req)

    fmt.Println(resp.Status)
    if resp.StatusCode == http.StatusOK {
        bodyBytes, _ := ioutil.ReadAll(resp.Body)
        bodyString := string(bodyBytes)
        fmt.Println(bodyString)
    }
}

要进行分页，您可以检查hasNextPage值以检查是否必须发送另一个查询以获取下一个100分叉回购，使用after中的RepositoryConnection获取给定游标后的100下一个值（存储前一个endCursor的值，如果hasNextPage是true）。

第一个要求：

{
  organization(login: "appcelerator-forks") {
    repositories(first: 100, isFork: true) {
      pageInfo {
        hasNextPage
        endCursor
      }
      edges {
        node {
          parent {
            nameWithOwner
          }
        }
      }
    }
  }
}

给"hasNextPage": true和"endCursor" : "Y3Vyc29yOnYyOpHOAQ1VZg=="。下一个请求将是：

{
  organization(login: "appcelerator-forks") {
    repositories(first: 100, isFork: true, after: "Y3Vyc29yOnYyOpHOAQ1VZg==") {
      pageInfo {
        hasNextPage
        endCursor
      }
      edges {
        node {
          parent {
            nameWithOwner
          }
        }
      }
    }
  }
}
