haproxy 2.0 dataplaneapi rest api 转为graphql
haproxy 2.0 dataplaneapi rest api 是比较全的，以下是一个简单的集成graphql，通过swagger-to-graphql转换为graphql api 方便使用
环境准备
- 项目准备
yarn init -yyarn add express express-graphql graphql swagger-to-graphql- 获取haproxy 2.0 dataplaneapi rest api swagger 定义
curl -s -X GET --user admin:dalong -H "Content-Type: application/json" http://localhost:5555/v1/specification > api.json- 代码
const express = require('express');const app = express();const graphqlHTTP = require('express-graphql');const graphQLSchema = require('swagger-to-graphql');# 使用basic auth 输入配置好的用户以及密码const proxyUrl = 'http://admin:dalong@localhost:5555/v1/';const pathToSwaggerSchema = './api.json';const customHeaders = { // Authorization: 'Basic YWRkOmJhc2ljQXV0aA=='};graphQLSchema(pathToSwaggerSchema, proxyUrl, customHeaders) .then(schema => { app.use( '/graphql', graphqlHTTP(() => { return { schema, graphiql: true, }; }), ); app.listen(3009, 'localhost', () => { ('http://localhost:3009/graphql'); }); }) .catch(e => { console.log(e); });- package.json 文件
{ "name": "haproxy-dataplaneapi2graphql", "version": "1.0.0", "main": "app.js", "license": "MIT", "dependencies": { "express": "^4.17.1", "express-graphql": "^0.9.0", "graphql": "^14.5.4", "swagger-to-graphql": "^2.1.0" }, "scripts": { "app": "node app.js" }} 启动&&效果
- 预备
首先需要有自己的haproxy 2.0 环境，同时配置了dataplaneapi - 启动
yarn app- 效果
- 查询效果
说明
以上是一个简单的集成，通过graphql 的查询api，我们可以方便的操作haproxy
