$ http POST从服务到控制器的响应 [英] $http POST response from service to controller

问题描述

在以下情况下如何获得服务部门的答复?

How to get the response from Service in below case??

服务:

app.factory('ajaxService', function($http) {
    updateTodoDetail: function(postDetail){
        $http({
            method: "POST",
            headers: {'Content-Type': 'application/x-www-form-urlencoded'},
            url: post_url,
            data: $.param({detail: postDetail})
        })
        .success(function(response){
            //return response;
        });
    }
})

控制器:

updated_details = 'xyz';
ajaxService.updateTodoDetail(updated_details);

在上述情况下，我通过Controller发布数据，并且工作正常，但现在我希望响应出现在Controller中.

In th above case, i POST the data through Controller and it was working fine but now i want the response to come in my Controller.

如何实现?

推荐答案

$http返回承诺:

兑现诺言

updateTodoDetail: function(postDetail){
    return $http({
        method: "POST",
        headers: {'Content-Type': 'application/x-www-form-urlencoded'},
        url: post_url,
        data: $.param({detail: postDetail})
    });

所以你可以做

ajaxService.updateTodoDetail(updated_details).success(function(result) {
    $scope.result = result //or whatever else.
}

或者，您可以将success函数传递给updateTodoDetail:

Alternatively you can pass the successfunction into updateTodoDetail:

updateTodoDetail: function(postDetail, callback){
    $http({
        method: "POST",
        headers: {'Content-Type': 'application/x-www-form-urlencoded'},
        url: post_url,
        data: $.param({detail: postDetail})
    })
    .success(callback);

您的控制器有

ajaxService.updateTodoDetail(updated_details, function(result) {
    $scope.result = result //or whatever else.
})

我希望使用第一个选项，这样我也可以在不传递那些函数的情况下处理错误等.

I would prefer the first option so I could handle errors etc as well without passing in those functions too.

(注意:我尚未测试上面的代码，因此可能需要进行一些修改)

(NB: I haven't tested the code above so it might require some modification)
