在Node.js中建立连接时出错

Question

I get the following message whenever I run the code

throw new Error('Most middleware (like ' + name + ') is no longer bundled with express and must be installed separately ^ Error: Most middleware(like BodyParser) is no longer bundled with Express and must be installed separately.

My code is as following:

var express = require("express"),
restful = require("node-restful");
mongoose = restful.mongoose;

var app = express();
app.use(express.bodyParser());
app.use(express.methodOverride());

mongoose.connect("mongodb://localhost/restful")

var ProductSchema = mongoose.Schema({
    name:String,
    sku:String,
    price:Number
});
var Products = restful.model("products", ProductSchema);
Products.methods(["get", "put", "post", "delete"]);
Products.register(app, "/api/products");

app.listen(3000);
Console.log("Server is running at port 3000")

I've installed npm body parser and npm method override separately but it still gives me the error message.

Answer 1

It seems to me that you do not require body-parser.

You should have something like var bodyParser = require('body-parser'); and then use it like app.use(bodyParser.json()); if you want the json parser for example.

Since it is no longer in express, you cannot require it and use it through express
