AngularJS两个http进入一个控制器时出现问题 [英] AngularJS two http get in one controller make problems

问题描述

我在一个控制器中有两个http GET，有时它可以工作，其中两个正在工作.有时只有一个http Get可以工作.有时没有显示出来. 有什么建议吗?

i have two http GET in one controller and sometimes it works and two of them are working. sometime only one http Get is work. and sometimes none of them is shown. any suggestions?

 }).controller("nextSidorAdminCtrl", 
 function($scope,$rootScope,$http,$location,$state) {
   $http.get("/ShiftWeb/rest/admin/getallsettingtime")
  .then(function(response) {
    $scope.settingtimes = response.data;
 });    
 $http.get("/ShiftWeb/rest/admin/nextsidor")
    .then(function(response) {
    $scope.nextsidor = response.data;
 });

推荐答案

绑定两个$ http.get操作:

Chain the two $http.get operations:

}).controller("nextSidorAdminCtrl", 
   function($scope,$rootScope,$http,$location,$state) {
       $http.get("/ShiftWeb/rest/admin/getallsettingtime")
       .then(function(response) {
           $scope.settingtimes = response.data;
           return $http.get("/ShiftWeb/rest/admin/nextsidor")
       })    
       .then(function(response) {
           $scope.nextsidor = response.data;
       });

由于调用promise的.then方法将返回新的派生promise，因此很容易创建promise的promise.可以创建任意长度的链，并且由于一个承诺可以用另一个承诺来解决(这将进一步推迟其解决方案)，因此可以在链中的任何点处暂停/推迟对这些承诺的解决.

Because calling the .then method of a promise returns a new derived promise, it is easily possible to create a chain of promises. It is possible to create chains of any length and since a promise can be resolved with another promise (which will defer its resolution further), it is possible to pause/defer resolution of the promises at any point in the chain.
