req.body为undefined

查看package.json中是下载过body-parser

如果没有则通过npm下载body-parser

var bodyParser = require('body-parser');

var app = express();

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
//以下为路由配置
var routes = require('./routes/index');
var users = require('./routes/users');
...other code...
