使用Apollo Client动态设置React组件的GraphQL查询

让我们以以下组件为例：

ProfileWithData.js

import React, { Component, PropTypes } from 'react';import { graphql } from 'react-apollo';import gql from 'graphql-tag';class Profile extends Component { ... }Profile.propTypes = {  data: PropTypes.shape({    loading: PropTypes.bool.isRequired,    currentUser: PropTypes.object,  }).isRequired,};// We use the gql tag to parse our query string into a query documentconst CurrentUserForLayout = gql`  query CurrentUserForLayout {    currentUser {      login      avatar_url    }  }`;const ProfileWithData = graphql(CurrentUserForLayout)(Profile);

用更高阶的组件将其包装起来非常容易：

Profile.js

import React, { Component, PropTypes } from 'react';export class Profile extends Component { ... }Profile.propTypes = {  data: PropTypes.shape({    loading: PropTypes.bool.isRequired,    currentUser: PropTypes.object,  }).isRequired,};

createProfileWithData.js

import React, { Component, PropTypes } from 'react';import { graphql } from 'react-apollo';import { Profile } from './Profile'export default function createProfileWithData(query) => {  return graphql(query)(Profile);}

然后，您可以像这样使用它：

Page.js

import React, { Component, PropTypes } from 'react';import gql from 'graphql-tag';import createProfileWithData from './createProfileWithData';class Page extends Component {  renderProfileWithData() {      const { textQuery } = this.props;      // Simplest way, though you can call gql as a function too      const graphQLQuery = gql`${textQuery}`;      const profileWithDataType = createProfileWithData(graphQLQuery);      return (        <profileWithDataType />      );  }  render() {    return (<div>     ..     {this.renderProfileWithData()}     ..</div>)  }}Profile.propTypes = {  textQuery: PropTypes.string.isRequired,};

我认为你说对了。

当然，不会收到您的个人资料

props.data.currentUser

props.data.*
