rest - GitHub API v4 : How can I traverse with pagination?(GraphQL)

Question

我正在使用 Github API v4 来运行搜索查询。

从API文档中我可以了解到以下查询为我提供了pageInfo，但我不知道如何使用它来遍历。

query {
  search(first: 100, type:USER, query:"location:usa repos:>0 language:java") {
    pageInfo {
      startCursor
      hasNextPage
      endCursor
    }
    userCount
    nodes {
        ... on User {
        bio
        company
        email
        id
        isBountyHunter
        isCampusExpert
        isDeveloperProgramMember
        isEmployee
        isHireable
        isSiteAdmin
        isViewer
        location
        login
        name
        url
        websiteUrl
      }
    }
  }
}

响应是:

{
    "data": {
        "search": {
            "pageInfo": {
                "startCursor": "Y3Vyc29yOjE=",
                "hasNextPage": true,
                "endCursor": "Y3Vyc29yOjEwMA=="
            },
    ...
}

根据graphql documentation分页模型不止一种。

GitHub 使用完整连接模型

在此模型中，您可以通过在搜索查询中添加 after:"Y3Vyc29yOjEwMA==" 来进行遍历。

query {
  search(first: 100, after:"Y3Vyc29yOjEwMA==", type:USER, query:"location:usa repos:>0 language:java") {
    pageInfo {
      startCursor
      hasNextPage
      endCursor
    }
    userCount
    nodes {
        ... on User {
        bio
        company
        email
        id
        isBountyHunter
        isCampusExpert
        isDeveloperProgramMember
        isEmployee
        isHireable
        isSiteAdmin
        isViewer
        location
        login
        name
        url
        websiteUrl
      }
    }
  }
}
