javascript - 将 angularjs 数据 ID 发送到我的 Node 服务器

Question

我想将 ID 发送到我的 Node 服务器。

但我不知道如何在服务器端获取它。请求已发送。console.log(req.body) 返回空...

Controller :

$scope.remove = function(id) {
    var idstring = JSON.parse(id);
    $http.delete('/contactlist/remove', {data: idstring}).then(function(response){
        $scope.contactlist = $scope.contactlist.filter(function(contact){
            return contact.id !== id;
        })
    });
};

服务器:

app.delete('/contactlist/remove', function (req, res) {
    console.log(req.body);
    // connection.query('DELETE FROM contactlist WHERE id = ' + req.body.id, function (error, results, fields) {
    res.json();
    // });
});

Chrome 中 DELETE 请求的屏幕截图:

无法在删除方法中发送数据

所以将删除网址设置为/contactlist/remove/3

$http.delete('/contactlist/remove/'+idstring).then(function(response){
        $scope.contactlist = $scope.contactlist.filter(function(contact){
            return contact.id !== id;
        })
    });

在服务器端

app.delete('/contactlist/remove/:idstring', function (req, res) {
    console.log(req.params.idstring);
    connection.query('DELETE FROM contactlist WHERE id = ' + req.params.idstring, function (error, results, fields) {
    res.json();
    });
});
