我想使用 cordova 和 angularjs 将数据发布到上述链接(尽管使用了 webservice)。我在两者之间使用警报来了解哪些功能正常工作。 sign Up Function 不起作用，它正在进入功能但没有进入请求方法来发布数据。
request.success(function(data)

如何将数据发布到 webservice( http://hmkcode.appspot.com/jsonservlet )
最佳答案
您必须按以下方式更改您的 Controller 。由于你使用的是新版本的angularjs，将.success改为.then。而且当你使用表单时，最好使用 ng-submit
JS:
$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";
}
});
}
HTML:
<form role="form" ng-submit="signUp()">
<div>
Name: <input type="text" ng-model="name"><br>
Country: <input type="text" ng-model="country"><br>
Twitter: <input type="text" ng-model="twitter"><br>
<button type="submit">Save</button><br>
<span>{{responseMessage}}</span>
</form>
