Question

您好我正在开发angularjs中的Web应用程序。我有一个带有两个工厂的java脚本文件，它们对web api进行http调用。我想在另一家工厂内使用一个工厂值输出。以下是我的第一家工厂

myapp.factory('sadadpaymentapi', ['$http', '$cookieStore', 'cfg', 'ScrollFunction', 'leaselisting','$q', function ($http, $cookieStore, cfg, ScrollFunction, leaselisting,$q) {
    var sadadpaymentapiobject = {};
    var baseurl = cfg.Baseurl;
    var LoginID = $cookieStore.get("LoginID");
    var cookiePreferredLanguage = $cookieStore.get('PreferredLanguage');
    var urlapi = baseurl + "api/ServiceRequest/CreateRSSedad/";
    sadadpaymentapiobject.callsadad = function (PaymentType) {
        var request = {
            url: urlapi,
            method: 'POST',
            data: {
                SRActivityID: LoginID,
                PaymentType: PaymentType,
                PaymentAmount: "100" //Need to get value from another factory
            },
            headers: ScrollFunction.getheaders()
        };
        return $http(request);
    }
    return sadadpaymentapiobject;
}]);

下面是另一家工厂，我可以在上面的工厂中获得PaymentAmount参数的值。

myapp.factory('leaselisting', ['$http', '$cookieStore', 'cfg', 'ScrollFunction','$q', function ($http, $cookieStore, cfg, ScrollFunction,$q) {
    var leaselistingobject = {};
    var baseurl = cfg.Baseurl;
    var LoginID = $cookieStore.get("LoginID");
    var cookiePreferredLanguage = $cookieStore.get('PreferredLanguage');
    leaselistingobject.getValue = function () {
        var requestObj = {
                                url: baseurl + "api/ServiceRequest/GetROLSPSRLeaseList/",
                                method:'POST',
                                data: {
                                    LoginID: LoginID,
                                    AccountNumber: $cookieStore.get("AccountNumber")
                                },
                                headers: ScrollFunction.getheaders()
                    };
        return $http(requestObj).then(function (response) {
            return response.data;
        });
    }
    return leaselistingobject;
}]);

当我像PaymentAmount一样注入：leaselisting.getValue（）并且如果我尝试在控制台中显示注入值console.log(leaselisting.getValue());我得到了Promise {$$ state等我附加了屏幕截图。我需要的是上图变量AccountNumber。

我正在尝试在第一个api，PaymentAmount：“100”而不是硬编码，我想从其他工厂获得它。我可以知道怎么做吗？任何帮助，将不胜感激。谢谢。

将工厂注入第二工厂，其余工作与您在控制器中的操作相同，

myapp.factory('leaselisting', ['$http', '$cookieStore', 'cfg', 'ScrollFunction','$q','sadadpaymentapi', function ($http, $cookieStore, cfg, ScrollFunction,$q,sadadpaymentapi) {

leaselisting工厂有调用asyc调用并解析它的方法getValue。

所以你可以写：

// ...
var request = {
        url: urlapi,
        method: 'POST',
        data: {
            SRActivityID: LoginID,
            PaymentType: PaymentType,
            PaymentAmount: leaselisting.getValue();
        },
 // ...

这是一个 Demo in Fiddle ，模拟你的情况。由于第二个异步调用是基于第一个，我会使用Promise链。在我的情况下，我使用$timeout模拟异步调用，返回地址的某些部分（在您的情况下为PaymentAmount），使用promise解析并调用其他Promise $http

app.controller('fessCntrl', function ($scope, sadadpaymentapi) {

    $scope.alertSwap = function () {           
        $scope.data = sadadpaymentapi.getData();    
    }; 
});

app.$inject = ['$scope', 'leaselisting'];

app.factory('leaselisting', ['$timeout','$q',  function($timeout, $q) {    

       var leaselistingobject = {
            getValue: function () {              
               var deferred = $q.defer();               
               $timeout(function(){                  
                return {address: 'Singapore, SG, Singapore, 153 Bukit Batok Street 1'};
               }, 3000).then(function(val){
               deferred.resolve(val); 
               });              
                return deferred.promise;
            }

       };       
        return leaselistingobject;
}]);


app.factory('sadadpaymentapi', ['$http','$q','leaselisting', function($http, $q,leaselisting) {  

       var leaselistingobject = {
            getData: function () {    

               var URL = 'http://maps.googleapis.com/maps/api/geocode/json?address=';  

               return leaselisting.getValue().then(function(result){

                URL = URL + result.address + '&sensor=true';

                 return $http({method: 'GET', url: URL})
                }).then(function (response) {
                   return response.data;
                 });
            }

       };       
        return leaselistingobject;
}]);

您好，您可以在控制器中执行以下操作：

 leaselisting.getValue().then(function(response){
         //you get account number here and pass it in another factory
           var accountNumber = response.data.AccountNumber;
          sadadpaymentapi.callsadad (accountNumber ).then(function(response){
                 //Do with your final response
          });
    });

和工厂代码：

myapp.factory('leaselisting', ['$http', '$cookieStore', 'cfg', 'ScrollFunction','$q', function ($http, $cookieStore, cfg, ScrollFunction,$q) {
        var leaselistingobject = {};
        var baseurl = cfg.Baseurl;
        var LoginID = $cookieStore.get("LoginID");
        var cookiePreferredLanguage = $cookieStore.get('PreferredLanguage');
        leaselistingobject.getValue = function () {
            var requestObj = {
                                    url: baseurl + "api/ServiceRequest/GetROLSPSRLeaseList/",
                                    method:'POST',
                                    data: {
                                        LoginID: LoginID,
                                        AccountNumber: accountNumber
                                    },
                                    headers: ScrollFunction.getheaders()
                        };
            return $http(requestObj)
        }
        return leaselistingobject;
    }]);

确保您已将两个工厂注入控制器

Angularjs在另外一个工厂
