将GET响应传递给POST

Question

I am trying to pass multiple maps of data dependent on the id selected to an export to Excel method.

I'm trying to use AngularJS to pass a JSON Array from a GET response to POST using this code:

$scope.exportExcel = function() {
var id='?';
angular.forEach($scope.selection, function(value, key) {
    id = id + "id=" + value + '&';
});

$http.get(searchUrl + id).success(
    function(response) { 
        $http.post(exportUrl, response);
    }
)}

The response of GET will be a JSON Array that looks like so (let's say Jason and Fred were both selected):

response = [{'id':'Jason', 'number':1}, {'id':'Fred', 'number':2}]

I have developed the Java code such that the input for the POST method should be like the array above.

I want the user to select the id's, press the EXPORT button, and immediately get a download dialog. No other screen changes or loads.

Is this feasible? Will my POST command be able to receive the JSONArray response from GET and successfully export?

Answer 1

No reason this won't work. Once the GET operation finished and called to its on-success function your code is in a whole new domain and the POST operation will function normally (it doesn't care or know where the data came from).

Answer 2

Just a quick attempt; Try this (if you can't work with this I'll need more info on what the value looks like -- I don't know the library you're using):

$scope.exportExcel = function() {
var id;
angular.forEach($scope.selection, function(value, key) {
    id = (id?id+"&":"?")
       + "id["+key+"]=" + encodeURIComponent(value.id)
       + "&number["+key+"]=" + value.number;
});

$http.get(searchUrl + id).success(
    function(response) { 
        $http.post(exportUrl, response);
    }
)}

Yes, it works. I just needed affirmation after all. I tested it and it works. Thanks for those who answered.
