Question

我有两个不同的查询。

第一个是在私人仓库中：

const query = `{
  repository(
    owner: "PrivateOrg"
    name: "privateRepoName"
  ) {
    name
    forkCount
    forks(
      first: 11
      orderBy: { field: NAME, direction: DESC }
    ) {
      totalCount
      nodes {
        name
      }
    }
  }
}`

第二个是在公共仓库中。在将其放入nodeJS应用之前，我已在Explorer上对其进行了测试-它可在资源管理器上运行：

const querytwo = `{
  repository(
    owner: "mongodb"
    name: "docs-bi-connector"
  ) {
    name
    forkCount
    forks(
      first: 27
      orderBy: { field: NAME, direction: DESC }
    ) {
      totalCount
      nodes {
        name
      }
    }
  }
}`

除查询外，两者的取景看起来都相同：

  fetch('https://api.github.com/graphql', {
  method: 'POST',
  body: JSON.stringify({query}),
  headers: {
    'Authorization': `Bearer ${accessToken}`,
  },
}).then(res => res.text())
  .then(body => console.log(body))
  .catch(error => console.error(error));
  console.log("\n\n\n");

    fetch('https://api.github.com/graphql', {
      method: 'POST',
      body: JSON.stringify({querytwo}),
      headers: {
        'Authorization': `Bearer ${accessToken}`,
      },
    }).then(res => res.text())
      .then(body => console.log(body))
      .catch(error => console.error(error));
    console.log("\n\n\n");

第一个查询返回：

{"data":{"repository":{"name":"mms-docs","forkCount":26,"forks":{"totalCount":8,"nodes":[{"name":"mms-docs"},{"name":"mms-docs"},{"name":"mms-docs"},{"name":"mms-docs"},{"name":"mms-docs"},{"name":"mms-docs"},{"name":"mms-docs"},{"name":"mms-docs"}]}}}}

但是第二个查询返回错误：

{"errors":[{"message":"A query attribute must be specified and must be a string."}]}

为什么会这样？

我尝试将第二个错误查询更改为在curl调用中看到的内容：

const querytwo = `query: {
      repository(
        owner: "mongodb"
        name: "docs-bi-connector"
      ) {
        name
        forkCount
        forks(
          first: 27
          orderBy: { field: NAME, direction: DESC }
        ) {
          totalCount
          nodes {
            name
          }
        }
      }
    }`;

但是我得到同样的错误

Answer 1

速记对象表示法错误

JSON.stringify({query})

是JSON.stringify({query: query})

的简写

变为

{
query: 
 {
      repository(
        owner: "PrivateOrg"
        name: "privateRepoName"
      ) {
        name
        forkCount
        forks(
          first: 11
          orderBy: { field: NAME, direction: DESC }
        ) {
          totalCount
          nodes {
            name
          }
        }
      }
    }
   }`

JSON.stringify({querytwo})是JSON.stringify({querytwo: querytwo})的简写

{
querytwo: 
 {
      repository(
        owner: "PrivateOrg"
        name: "privateRepoName"
      ) {
        name
        forkCount
        forks(
          first: 11
          orderBy: { field: NAME, direction: DESC }
        ) {
          totalCount
          nodes {
            name
          }
        }
      }
    }
   }`

为什么GraphQL找不到query-它找到了queryTwo

Github GraphQL错误：必须指定查询属性，并且必须是字符串
