我的api / addmasterlist无效，它给了我不能GET / api / addmasterlist 浏览器出错在masterlist上使用app.get看起来工作得很好并反映在数据库上问题是它对我的angular.js不起作用

好吧使用app.get似乎工作，但任何人都可以帮助我这是推动nodejs的正确方法吗？使用角度

$scope.saveNewStudent = function(){
    var dataa =  $scope.studentmasterlist.push({
        id: ($scope.studentmasterlist.length + 1),
        studentid: $scope.studentid,
        studentname: $scope.studentname,
        course: $scope.course,
        year: $scope.year,

    });

 $http.get('/api/addmasterlist', dataa).success(function(data, status) {
    console.log('Data posted successfully');
  })
    //Clear the scope
    $scope.studentid = "";
    $scope.studentname = "";
    $scope.course = "";
    $scope.year = "";

}

Answer 1

问题是您将/api/addmasterlist端点声明为POST请求。尝试将其更改为GET，它可能会按预期工作。

改变这个：

app.post('/api/addmasterlist', function(req, res){

对此：

app.get('/api/addmasterlist', function(req, res){

或者，你可以改变角度的http来自发布：

变化：

$http.get('/api/addmasterlist', dataa).success(function(data, status) {

到

$http.post('/api/addmasterlist', dataa).success(function(data, status) {

不能在app.post上获取/ api / addmasterlist
