javascript - 如何从node.js函数将变量传递到graphql-tag？(How to pass variables into graphql-tag from node.js function?)

Question

I have the following function:(我有以下功能：)

import ApolloClient from 'apollo-boost' import gql from 'graphql-tag' import fetch from 'node-fetch' global.fetch = fetch const client = new ApolloClient({ uri: 'myUri' }) const getPostsByCategory = async category => { const res = await client.query({ query: gql` query articlesByCategory($id: String!) { postsByCategory(id: $id) { id } } ` }) console.log('res', res) } I want to invoke the function as:(我想将函数调用为：) await getPostsByCategory('news') however I just can't understand how I pass the category variable into the query.(但是我只是不明白如何将类别变量传递给查询。) I want to use qraphql-tag in my queries and not pass a simple tagged literal as the query.(我想在查询中使用qraphql-tag ， qraphql-tag要将简单的带标记文字作为查询传递。)   ask by hitchhiker translate from so

You can use the variables key in your client.query function params as the following(您可以在client.query函数参数中使用variables键，如下所示)

const getPostsByCategory = async category => { const res = await client.query({ query: gql` query articlesByCategory($id: String!) { postsByCategory(id: $id) { id } } `, variables: { id: category, }, }); console.log('res', res); };
