Question

在尝试发布到mongodb时，我对来自angularjs的挂起$ http.post请求有疑问。我的app.js：

app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.static(__dirname + '/public'));
app.use('/bower_components', express.static(__dirname + '/bower_components'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.methodOverride());
app.use(app.router);

我的路线：js for post：

self.routeTable.push({

    requestType : 'post',
    requestUrl : '/getAllPrjProjections',
    callbackFunction : function (request, response) {
        console.log(request.body.pr_code);
        console.log(request.body.high_low);
        console.log(request.body);

        var prjProjectionsDao = require('../Server/Dao/prjProjectionsDao.js');

        prjProjectionsDao.create({
            pr_code : request.body.pr_code,
            high_low : request.body.high_low,
            subs_rate : request.body.subs_rate,
            prj_month : request.body.prj_month,
            prj_value : request.body.prj_value,
            last_saved : request.body.last_saved
        }, function(err, todo) {
            console.log(todo);
            if (err) {
                console.log('bbb');
                response.send(err);
            }
        });
    }
});

在控制器中，当用户单击saveProjections按钮时，我实现了以下功能：

$scope.saveProjections = function() {
    $scope.prj_to_save = {"pr_code":"PGU","high_low":"HIGH","subs_rate":"Paid Subs","prj_month":"2016-10-01","prj_value":"96000","last_saved":"2016-12-07"};
    var data_to_send = JSON.stringify($scope.prj_to_save);

    prjProjectionsService.saveProjections($scope.prj_to_save).then(function(success) {
       // $scope.formData = {};
        console.log(data, 'Blog created.');
    },function (error) {
        console.log("The request failed: " + error.data);

    });
};

注入的服务器如下：

function saveProjections(prjData){
        return $http.post('/getAllPrjProjections', prjData).then(function (success) {
            console.log('success');
        }, function (error) {
            console.log('error');
        });
    }

问题是请求长时间处于挂起状态（附加的版画屏幕），然后失败并显示错误：＆＃34; XMLHttpRequest：网络错误0x2ef3，由于错误00002ef3＆＃34;

无法完成操作

但是，数据发布在mongodb中。你能帮帮我吗？我将不胜感激。

您只是在发生错误时发送回复，所以在成功的情况下也会发送内容

object

AngularJS $ http.post json请求表达挂起状态
