无法在快递中检索邮政参数

Question

我的角色邮政编码：

    userModule.controller('registrationController', function($scope, $http){
    $scope.Name = "";
    $scope.Email = "";
    $scope.Password = "";
    $scope.Repeat = "";
    $scope.register = function () {
        if ($scope.Name.length == 0){
            swal("Please enter your name!", "", "error");
            return;
        }
        if ($scope.Email.length == 0){
            swal("Please enter your email!", "", "error");
            return;
        }
        if ($scope.Password.length == 0){
            swal("Please enter your password!", "", "error");
            return;
        }
        if ($scope.Password !== $scope.Repeat){
            swal("Passwords do not match!", "", "error");
            return;
        }

        var data = $.param({
            Name: $scope.Name,
            Email_id: $scope.Email,
            Password: $scope.Password
        });

        var config = {
            headers : {
                'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
            }
        };

        $http.post("http://localhost:8000/register", data, config).then
        (
            //Success Callback
            function (res) {
                /*if (res.data.Status == 1)
                    swal("Success", res.data.Message, "success");
                else
                    swal("Error", res.data.Message, "error");

                $scope.Name = null;
                $scope.Email = null;
                $scope.Password = null;
                $scope.Repeat = null;*/
                alert(res.data.success);
            },
            //Error Callback
            function () {
                $scope.registrationResponse = "";
                swal("Request couldn't be sent!", "", "error");
            }
        );
    };
});

快递：

1）app.js：

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

var app = express();
var port = 8000;

app.use('/', express.static('./style'));
app.use('/', express.static('./node_modules'));
app.use('/', express.static('./js'));
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());

require('./server/routes')(app);

app.listen(port, function(error, response){
    if (error){
        console.log("Failed to run server!");
    }
});


module.exports = app;

2）route / index.js：

module.exports = function (app) {

    app.get('/', function (req, res) {
        res.sendFile('index.html', {root:'./view/'});
    });

    app.get('/index', function(req, res){
        res.sendFile('index.html', {root:'./view/'});
    });

    app.post('/login', function(req, resp){
        resp.json({"success":"OK"});
    });

    app.post('/register', function(req, resp){
        //registerUser(req.body.params);
        console.log(req.headers);
        console.log(req.body);
        resp.json({"success":"OK"});
    })
};

我还尝试过：req.params, req.query并且所有这些都是空的。 我做错了什么？

输出：

req.header:

{ host: 'localhost:8000',
  connection: 'keep-alive',
  'content-length': '48',

  dnt: '1',
  referer: 'http://localhost:8000/',
  'accept-encoding': 'gzip, deflate, lzma',
  'accept-language': 'en-US,en;q=0.8' }

req.body:

undefined

Answer 1

对于express并使用body-parser，当您致电req.params时，指的是根据您的路线规范传递的网址参数。

例如，如果我有一个已定义的路线：

/* User goes to /sample/example */
app.get('/sample/:value', (req, res) => {
    var value = req.params.value;
});

然后变量value保存字符串example。

要在POST中获取express请求的正文，请使用req.body.# - 其中#是POST数据{{1}中的关键字}}。因此，对于json，json会返回req.body.connection。

Answer 2

您设置的内容类型标题无效：

'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'

后面的分号不应该在那里，所以它应该是这样的：

'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'

Answer 3

你可以尝试记录整个req对象，我打赌你不会在任何地方看到你的参数。我怀疑你正在阅读它们，但它们不存在 - ＆gt;他们没有被正确发送，或者他们在到达你的路线之前被过滤掉了。

您可以使用像Postman这样的免费工具来测试此假设，以便以正确的格式（json / form）向您的应用程序发送带有所需参数的POST请求。
