Send array of objects via GET request with Angular's $http to Java Spring

问题

I have a javascript variable which is an array of MyObjects. I can display this variable to the view with the following code:

        <tr ng-repeat="user in lala.users">
            <td>{{ user.firstName }}</td>
            <td>{{ user.lastName }}</td>
        </tr>

Now I am trying to send this array to the server. I am trying something like:

    lala.send = function() {
        $http({
            method: 'GET',
            url: "http://localhost:8080/server/" + lala.users
        }).then(function successCallback(response) {
            if (response.status == 200) {
                lala.users = response.data
            }
        });
    };

How can I pass this array to a list on the server side? Till now I have something like this.

@RequestMapping(value = "/server/{users}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<List<MyObjects>> transform(@PathVariable("users") String[] users) {
        List<MyObjects> results2 = new ArrayList<>();

        //pass array to a list??

        return new ResponseEntity<>(results2, HttpStatus.OK);
    }

回答1:

You can transform your string and use a delimiter, then parse it on your server side. You can also use HttpPost instead of HttpGet request so you can send JSON String and it is easier to parse.

Based on Ranielle's answer I proceeded with HttpPost.

Here is the code:

lala.send = function() {
            $http.post("http://localhost:8080/server", lala.users ) 
            .then(function successCallback(response) {
                if (response.status == 200) {
                   lala.users = response.data
                }
            });
        };

And the Spring side

@RequestMapping(value = "server", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<List<MyObjects> sort( @RequestBody List<MyObjects> query) {
        List<MyObjects> results2 = new ArrayList<>();

        for(MyObjects a : query) {
                System.out.println(a.getFirstName());
        }

        return new ResponseEntity<>(results2, HttpStatus.OK);
    }
