Question

我想使用webservice和cordova将数据发布到上述链接（尽管使用angularjs）。我之间使用过警报来了解哪些功能正常工作。注册功能不起作用，它正在进入功能但没有输入请求方法来发布数据。 request.success(function(data)

中是否有任何错误

如何将数据发布到webservice（http://hmkcode.appspot.com/jsonservlet）

Answer 1

您必须按以下方式更改控制器。由于您使用的是新版本的angularjs，请将TextViews更改为.success。而且当您使用表单时，最好使用.then

<强> JS ：

ng-submit

<强> HTML ：

$scope.signUp = function () {
                /*  $scope.Message = "Button clicked."*/
                alert("Button CLicked");;
                var request = $http({
                    method: "post",
                    dataType:'json',
                    url: "http://hmkcode.appspot.com/jsonservlet",
                    crossDomain : true,
                    data: {
                        'name': $scope.name,
                        'country': $scope.country,
                        'twitter': $scope.twitter
                    },
                        headers: { 'Accept':' text/plain','Content-Type': 'application/json' }
                });
                /* Successful HTTP post request or not */
                request.then(function(data) {
                    alert("success function");
                    if(data.data == "1"){
                        $scope.responseMessage = "Successfull";
                    }
                    if(data.data == "2"){
                        $scope.responseMessage = "failed";
                    } else if(data.data == "0") {
                        $scope.responseMessage = "Error";
                    }  
                });
            }
