Question

我正在使用angular将数据发送到节点服务器，但它无法正常工作。我无法在我的node post方法中看到我的帖子数据（表单中的输入值）。我需要将数据保存在mongoDb中，但我不知道为什么我看不到前端发送的POST值。

我无法通过console.log（）在节点中看到我的表单数据。有时它返回{}，当我使用

时，有时POST被'morgan'调试器识别为OPTIONS req

console.log(req.body.fname);

我的Html：

        })
    </script>
    </body>

我的节点代码：

    require('rootpath')();
    var express = require('express');
    var app = express();
    var bodyParser = require('body-parser');
    var morgan = require('morgan');
    var mongoose = require('mongoose');

    var jwt = require('jsonwebtoken');
    var config = require('config.json');
    app.set('view engine', 'ejs');
    app.set('views', __dirname + '/views');

    var port = process.env.PORT || 3000;
    mongoose.connect(config.connectionString);
    app.set('superSecret', config.secret);
    app.use(bodyParser.urlencoded({extended: true}));
    app.use(bodyParser.json());
    app.use(morgan('dev'));
    app.post('/api/post', function (req, res) {
        console.log(req.body.fname);
    });
    app.listen(port);
    console.log('Magic happens at http://localhost:' + port);

感谢。

请添加您的模块

$httpProvider.defaults.headers.post['Content-Type'] = 
'application/x-www-form-urlencoded;charset=utf-8';

从角度到节点的POST数据不起作用
