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？

答案 0 :(得分：0)
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。
答案 1 :(得分：0)
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'
答案 2 :(得分：0)
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。
