将 graphql 查询 .gql 文件导入纯 Javascript 和 运行 一个 axios 调用

Import graphql query .gql file into plain Javascript and run an axios call

我有一个简单的 axios 调用,我想调用它来获取一些 graphql 数据。 我还有一个 .gql 文件,我想将其导入以用作查询:

pages.gql

{
  entries(section: [pages]) {
    uri
    slug
  }
}

现在我想在我的其他文件中导入:

import query from './queries/pages.gql'

稍后进行 axios 调用:

const routes = await axios.post(
    endpoint,
    { query },
    { headers: { Authorization: `Bearer ${token}` } }
  )
  .then(result => {
    console.log('result: ', result)
  })
  .catch(error => {
    console.log('error: ', error)
  })

但是每当我这样做时,我都会得到这个错误:

missing ) after argument list 09:55:25

entries(section: [pages]) {

^^^^^^^

SyntaxError: missing ) after argument list

所以我不能只导入 gql 文件。 我已导入 graphql-tag (import gql from 'graphql-tag'),所以我可以这样做:

const QUERY = gql`
  ${query}
`

但首先我必须导入 gql 文件,对吗?

任何帮助将不胜感激... 干杯

好的,另一种情况:

我有一个非常有用的 axios 调用:

await axios
    .post(
      endpoint,
      { query: `query Page($slug: String!) {
          entries(section: [pages], slug: $slug) {
            slug
            title
          }
        }`,
        variables: { slug: params.slug }
      },
      { headers: { Authorization: `Bearer ${env.GRAPHQL_TOKEN}` } }
    ).then(result => {
      console.log('result: ', result)
    })
    .catch(error => {
      console.log('error: ', error)
    })

我还有一个 page.gql 文件,内容完全相同:

query Page($slug: String!) {
  entries(section: [pages], slug: $slug) {
    slug
    title
  }
}

我发现像这样导入 page.gql 文件 import page from '~/apollo/queries/page' 将导入这种结构的东西:

    page:  {                                                                                                                                         15:16:40
        kind: 'Document',
        definitions: [...],
        loc: {
            start: 0,
            end: 181,
            source: {
            body: 'query Page($slug: String!) {\n  ' +
                'entries(section: [pages], slug: $slug) {\n    ' +
                'slug\n    title\n   }\n  }\n}\n',
            name: 'GraphQL request',
            locationOffset: [Object]
            }
        },
        Page: {...}
    }

所以要在我的查询中使用 page.gql 我必须使用这个 page.loc.source.body:

  await axios
    .post(
      endpoint,
      { query: page.loc.source.body,
        variables: { slug: params.slug }
      },
      { headers: { Authorization: `Bearer ${env.GRAPHQL_TOKEN}` } }
    ).then(result => {
      console.log('result: ', result)
    })
    .catch(error => {
      console.log('error: ', error)
    })

还有比这更好的方法吗?

graphql 标签模板文字(gql`..`)将 graphql 查询解析为 AST(抽象语法树;进一步阅读:https://www.contentful.com/blog/2018/07/04/graphql-abstract-syntax-tree-new-schema/). The advantage of parsing to an AST (on the client-side) is that it allows you to lint your queries and eases query handling e.g. with fragments (see: https://github.com/apollographql/graphql-tag#why-use-this

如果您想将查询传递给 axios/fetch,您需要使用 graphql 打印机 fn (https://graphql.org/graphql-js/language/#printer):[=14= 将其解析回实际的查询字符串]

import gql from 'graphql-tag';
import { print } from 'graphql/language/printer';

const AST = gql`
  {
    user(id: 5) {
      firstName
      lastName
    }
  }
`
const query = print(AST);
