app.js restapi 转 graphql
require(‘babel-polyfill‘);
const express = require(‘express‘);
const app = express();
const graphqlHTTP = require(‘express-graphql‘);
const graphQLSchema = require(‘./lib‘); // 类型映射
const proxyUrl = ‘https://petstore.swagger.io/v2‘;
const pathToSwaggerSchema = `${__dirname}/api/s.json`; // swagger api 描述
const customHeaders = {
Authorization: ‘Basic YWRkOmJhc2ljQXV0aA==‘
};
graphQLSchema(pathToSwaggerSchema, proxyUrl, customHeaders).then(schema => {
app.use(‘/graphql‘, graphqlHTTP(() => {
return {
schema,
graphiql: true
};
}));
app.listen(3009, ‘0.0.0.0‘, () => {
console.info(‘http://localhost:3009/graphql‘);
});
}).catch(e => {
console.log(e);
});
