Question

我有一个api（'rest / latest / testruns / 16543558'）id是test run ids。我想在oneshot中使用不同的id进行调用，并在我的视图中将值存储在对象中以进行ng-repeat。

$http
  .get('rest/latest/testruns/' + testplanid)
  .success(function (response) {
    $scope.testruns = response;
  })
  .error(function (data, status) {

  });

Answer 1

可以使用$q.all一次发送多个http请求。

 var ids = ['16543558', '16543559', '165435510']
 var fullArr = [];

 for (id in ids) {
    fullArr.push($http.get("rest/latest/testruns/" + id))
 }

 $q.all(fullArr).then(function(arrayOfResults) {
    //return the response of all equest
 });

Answer 2

您可以使用下面的$q.all来实现类似的行为

var ids=[1,2,3,4,5], promises;

promises = ids.map(function(v){
return $http
  .get('rest/latest/testruns/' + v)
});

$q.all(promises).then(function(responses){
  // responses[0]  => id 1
  // responses[1]  => id 2
  // responses[2]  => id 3
  // responses[3]  => id 4
  // responses[4]  => id 5
})

Answer 3

您可以使用$ q.all来实现多个承诺调用。

HTML code：

<div ng-app>
  <div ng-controller="PromiseCtrl">
      {{result}}
  </div>
</div>

控制器功能：

function PromiseCtrl($scope, $q, $timeout) {
    // Our promise function with its delay as argument
    var getPromise = function(delay) {
        // Creates a Deferred object
        var deferred = $q.defer();

        $timeout(function() {
            // Resolve the promise at the end of the delay if said delay was > 0
            if(delay > 0) {
                deferred.resolve("Success");
            } else {
                deferred.reject("Fail");
            }
        }, delay);

        // The promise of the deferred task
        return deferred.promise;
    };

    // Init
    $scope.result = "Waiting";

    /*
     * Combines multiple promises into a single promise
     * that will be resolved when all of the input promises are resolved
     */
    $q.all([
            getPromise(1000),
            getPromise(2000),
            getPromise(3000) // <--- Try something less than 0
        ]).then(function(value) {
        // Success callback where value is an array containing the success values
        $scope.result = value;       
    }, function(reason) {
        // Error callback where reason is the value of the first rejected promise
        $scope.result = reason;
    });
}
