表达js api终点在azure web app

Question

我刚尝试使用Express js创建一个测试API应用程序。我在互联网上采用了许多方法来部署和运行node js api app。但在我的情况下，没有任何工作。请帮帮我。

其他方面我将不得不离开azure或节点js。

我附上以下所有文件： 1.index.js

var express = require('express');
var app = express();


router.get('/things', function(req, res) {
    res.json('GET route on things.');
});
router.post('/things', function(req, res) {
    res.json('POST route on things.');
});

app.get('/hello', function(req, res) {
    res.json("Hello World!");
});

app.post('/hello', function(req, res) {
    res.json("You just called the post method at '/hello'!\n");
});

const port = process.env.PORT || 1337;
app.listen(port);

2.包装-lock.json

{
    "name": "testabc",
    "version": "1.0.0",
    "description": "test api",
    "main": "index.js",
    "engines": {
        "node": "^7.10.0"
    },
    "scripts": {
        "test": "test",
        "start": "node index.js",
        "prestart": "npm install"
    },
    "repository": {
        "type": "git",
        "url": "none"
    },
    "keywords": [
        "test"
    ],
    "author": "rakesh",
    "license": "ISC",
    "dependencies": {
        "express": "^4.16.2"
    }
}

3.package.json

{
    "name": "testabc",
    "version": "1.0.0",
    "description": "test api",
    "main": "index.js",
    "engines": {
        "node": "^7.10.0"
    },
    "scripts": {
        "test": "test",
        "start": "node index.js",
        "prestart": "npm install"
    },
    "repository": {
        "type": "git",
        "url": "none"
    },
    "keywords": [
        "test"
    ],
    "author": "rakesh",
    "license": "ISC",
    "dependencies": {
        "express": "^4.16.2"
    }
}

4.web.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.webServer>
        <handlers>
            <add name="iisnode" path="index.js" verb="*" modules="iisnode" />
        </handlers>   
        <rewrite>
      <rules>
        <rule name="myapp">
          <match url="/*" />
          <action type="Rewrite" url="index.js" />
        </rule>
      </rules>
    </rewrite>         
    </system.webServer>
</configuration>

Answer 1

var express = require('express');
var app = express();
var router = express.Router();

router.get('/things', function(req, res) {
    res.json('GET route on things.');
});
router.post('/things', function(req, res) {
    res.json('POST route on things.');
});

app.get('/hello', function(req, res) {
    res.json("Hello World!");
});

app.post('/hello', function(req, res) {
    res.json("You just called the post method at '/hello'!\n");
});

const port = process.env.PORT || 1337;
app.listen(port);

如果您将其更改为：

，这将有效

var express = require('express');
var app = express();

//****************************************
app.route('/things')
    .get(function (req, res) {
        res.json('GET route on things.');
    })
    .post(function (req, res) {
        res.json('POST route on things.');
    })
//****************************************
// or
//****************************************
var router = express.Router();
router.get('/', function (req, res) {
    res.json('GET route on things.');
});
router.post('/', function (req, res) {
    res.json('POST route on things.');
});
app.use('/things', router);
//****************************************

app.get('/hello', function (req, res) {
    res.json("Hello World!");
});

app.post('/hello', function (req, res) {
    res.json("You just called the post method at '/hello'!\n");
});

const port = process.env.PORT || 1337;
app.listen(port);

该应用现在可以处理以下请求：

• GET /things
• POST /things
• GET /hello
• POST /hello
