准备工作 申请一个免费的MongoDB
到
https://www.mlab.com
注册申请一个500M的MongoDB数据库。登录后手动在创建Databases下的Collections中手动创建一个数据库node_app。在个人首页点击Connect获取node.js连接MongoDB数据库的字符串为
mongodb+srv://:@cluster0.ylpaf.mongodb.net/node_app
将其中
下载安装Postman
到
https://www.postman.com/
注册一个账号,下载安装Postman agent,即可方便地进行GET/POST/PUT等测试。【node.js+postman+mongodb搭建测试注册接口的实现】
mongodb连接串配置 安装mongoose用于连接数据库:
> npm install mongoose> > cd C:\Users\xiaoming\source\repos\node_demo\node_app> mkdir config> cd config> new-item keys.js -type file
编辑keys.js配置连接串:
module.exports = {mongoURI: "mongodb+srv://:@cluster0.ylpaf.mongodb.net/node_app"}
编辑server.js入口文件:
const express = require("express"); const mongoose = require("mongoose"); const app = express(); const db = require("./config/keys").mongoURI; mongoose.connect(db).then(() => console.log("MongoDB connected.")).catch(err => console.log(err)); app.get("/", (req, res) => {res.send("Hello World!"); })const port = process.env.PORT || 5000; app.listen(port, () => {console.log(`Server running on port ${port}`); })
检查是否能连接到数据库:
> nodemon server.js[nodemon] 2.0.16[nodemon] to restart at any time, enter `rs`[nodemon] watching path(s): *.*[nodemon] watching extensions: js,mjs,json[nodemon] starting `node server.js`Server running on port 5000MongoDB connected.
数据库连接正常。
GET请求测试 创建路由文件
C:\Users\xiaoming\source\repos\node_demo\node_app\routes\api\users.js
编辑users.js并添加GET请求:
// login & registtrationconst express = require("express"); const router = express.Router(); router.get("/test", (req,res) => {res.json({msg:"Login succeeded!"})})module.exports = router;
编辑server.js,导入并使用users.js:
const express = require("express"); const mongoose = require("mongoose"); const app = express(); const users = require("./routes/api/users"); const db = require("./config/keys").mongoURI; mongoose.connect(db).then(() => console.log("MongoDB connected.")).catch(err => console.log(err)); // 设置app路由app.get("/", (req, res) => {res.send("Hello World!"); })// 使用usersapp.use("/api/users", users); const port = process.env.PORT || 5000; app.listen(port, () => {console.log(`Server running on port ${port}`); })
访问
http://localhost:5000/api/users/test
可以看到
{"msg":"Login succeeded!"}
注册接口搭建
创建User数据模型
创建用户数据模型文件
C:\Users\xiaoming\source\repos\node_demo\node_app\models\User.js
编辑User.js创建用户数据模型:
const mongoose = require("mongoose"); const Schema = mongoose.Schema; // create Schemaconst UserSchema = new Schema({name:{type: String,required: true},email: {type: String,required: true},password: {type: String,required: true},avatar: {type: String},date: {type: Date,default: Date.now},})module.exports = User = mongoose.model("users", UserSchema);
使用body-parser中间件
安装body-parser中间件,可以方便地处理HTTP请求。
> npm install body-parser
编辑server.js使用body-parser:
const express = require("express"); const mongoose = require("mongoose"); const bodyParser = require("body-parser"); const app = express(); const users = require("./routes/api/users"); const db = require("./config/keys").mongoURI; app.use(bodyParser.urlencoded({ extended: false })); app.use(bodyParser.json()); mongoose.connect(db).then(() => console.log("MongoDB connected.")).catch(err => console.log(err)); app.get("/", (req, res) => {res.send("Hello World!"); })app.use("/api/users", users); const port = process.env.PORT || 5000; app.listen(port, () => {console.log(`Server running on port ${port}`); })
POST请求测试
编辑users.js增加POST请求:
// @login & registtrationconst express = require("express"); const router = express.Router(); /* * $route GET /api/users/test * @desc return requested json data * @access public */router.get("/test", (req,res) => {res.json({msg:"Login succeeded!"})})/* * $route POST /api/users/register * @desc return requested json data * @access public */router.post("/register", (req, res) => {console.log(req.body); })module.exports = router;
POST中暂时只有一个打印请求体的操作。
在Postman中的Workspace中测试:
POST http://localhost:5000/api/users/register
Body选择x-www-form-urlencoded,在KEY和VALUE中填入测试内容:
KEYVALUEemailharlie@google.com
查看终端输出:
Server running on port 5000说明成功获取到了req.body。
MongoDB connected.
[Object: null prototype] { email: 'harlie@google.com' }
使用User数据模型
首先安装bcrypt包。bcrypt可以用来加密注册用户的密码,避免在数据库中存储明文密码。在https://www.npmjs.com/上可以查看bcrypt包的用法介绍。
> npm install bcrypt
编辑users.js引入并使用User数据模型:
// @login & registtrationconst express = require("express"); const router = express.Router(); const bcrypt = require("bcrypt"); const User = require("../../models/User.js"); /* * $route GET /api/users/test * @desc return requested json data * @access public */router.get("/test", (req,res) => {res.json({msg:"Login succeeded!"})})/* * $route POST /api/users/register * @desc return requested json data * @access public */router.post("/register", (req, res) => {//console.log(req.body); // check if email already existsUser.findOne({ email: req.body.email }).then((user) => {if (user) {return res.status(400).json({ email: "邮箱已被注册!" })} else {const newUser = new User({name: req.body.name,email: req.body.email,password: req.body.password})// encrypt newUser passwordbcrypt.genSalt(10, function (err, salt) {bcrypt.hash(newUser.password, salt, (err, hash) => {if (err) throw err; newUser.password = hash; newUser.save().then(user => res.json(user)).catch(err => console.log(err)); }); }); }})})module.exports = router;
在Postman中的Workspace中测试POST http://localhost:5000/api/users/register。Body选择x-www-form-urlencoded,在KEY和VALUE中填入测试内容:
emailgodfrey@eldenring.comnamegodfreypassword123456
查看测试输出
{"name": "godfrey","email": "godfrey@eldenring.com","password": "$2b$10$hoGzFeIdZyCwEotsYhxEheoGNOCE4QnYYh/WkKoGkuPT0xZI9H10C","_id": "62a4482c00990937d819ea6d","date": "2022-06-11T07:45:48.437Z","__v": 0}
打开mongodb,在DATABASES下的node_app中查看,会发现多出了一个users的Collection,其中刚好存储了上面我们刚通过POST请求插入的一条数据。
使用gravatar处理头像
在https://www.npmjs.com/package/gravatar中查看gravatar的使用方法。
安装gravatar
> npm i gravatar
编辑users.js增加注册头像(avatar)处理:
// @login & registtrationconst express = require("express"); const router = express.Router(); const bcrypt = require("bcrypt"); const gravatar = require("gravatar"); const User = require("../../models/User.js"); /* * $route GET /api/users/test * @desc return requested json data * @access public */router.get("/test", (req,res) => {res.json({msg:"Login succeeded!"})})/* * $route POST /api/users/register * @desc return requested json data * @access public */router.post("/register", (req, res) => {//console.log(req.body); // check if email already existsUser.findOne({ email: req.body.email }).then((user) => {if (user) {return res.status(400).json({ email: "Email already registered!" })} else {const avatar = gravatar.url(req.body.email, { s: '200', r: 'pg', d: 'mm' }); const newUser = new User({name: req.body.name,email: req.body.email,avatar,password: req.body.password})// encrypt newUser passwordbcrypt.genSalt(10, function (err, salt) {bcrypt.hash(newUser.password, salt, (err, hash) => {if (err) throw err; newUser.password = hash; newUser.save().then(user => res.json(user)).catch(err => console.log(err)); }); }); }})})module.exports = router;
在Postman中的Workspace中测试POST http://localhost:5000/api/users/register,Body选择x-www-form-urlencoded。
在KEY和VALUE中填入测试内容:
emailgodfrey@eldenring.comnamegodfreypassword123456
测试会返回报错
{"email": "Email already registered!"}
在KEY和VALUE中填入测试内容:
emailmohg@eldenring.comnamemohgpassword123456
测试返回
{"name": "mohg","email": "mohg@eldenring.com","password": "$2b$10$uSV2tmA5jH6veLTz1Lt5g.iD5QKtbJFXwGsJilDMxIqw7dZefpDz.","avatar": "//www.gravatar.com/avatar/c5515cb5392d5e8a91b6e34a11120ff1?s=200&r=pg&d=mm","_id": "62a44f12d2c5293f0b8e9c2b","date": "2022-06-11T08:15:14.410Z","__v": 0}
