我在尝试使用graphQL时遇到了问题。我想我在架构或解析器上做错了。根据文档的所有内容,但仍然无法获取数据。
我需要的是非常简单的用户模型,以便在graphiql中运行查询。
这是我的代码:Download code (zip file)(node-7.5的代码) 然后只需运行 npm install 和 npm run build 。
主要文件:server.js,schema.js,models / user.js和resolvers / user.js。
模型/ user.js的
const typeDefinitions = `
type User {
id: String!
name: String
type: Int
isActive: Boolean
clients: [String]
}
schema {
query: User
}
`;
export default [typeDefinitions]
解析器/ user.js的: -
const resolverMap = {
User: {},
};
export default resolverMap
schema.js
import { makeExecutableSchema } from 'graphql-tools';
import resolver from '../resolvers/user'
import User from './user';
export default makeExecutableSchema({
typeDefs: User,
resolvers: resolver,
});
server.js: -
import express from 'express';
import bodyParser from 'body-parser';
import routes from './app/routers/index';
import { graphqlExpress } from 'graphql-server-express';
import schema from './app/models/schema'
var app = express(); // create our app w/ express
var database = require('./app/configs/database');
var port = process.env.PORT || 8888; // set the port
app.use(express.static(__dirname + '/public')); // set the static files location /public/img will be /img for users
app.use(morgan('dev')); // log every request to the console
app.use(bodyParser.urlencoded({ 'extended': 'true' })); // parse application/x-www-form-urlencoded
app.use(bodyParser.json()); // parse application/json
app.use(bodyParser.json({ type: 'application/vnd.api+json' })); // parse application/vnd.api+json as json
app.use('/graphql', bodyParser.json(), graphqlExpress({
graphiql: true,
pretty: true,
schema: schema
}));
app.listen(port);
console.log("App listening on port : " + port);
答案 0 :(得分:1)
import { graphiqlExpress } from 'graphql-server-express';
app.use('/graphiql', graphiqlExpress({
endpointURL: '/graphql',
}));
您需要使用上面的代码,
我猜不再支持{p>graphiql: true
了,
您需要导入graphiql方法并为相同的传递端点
