How to pass a JSON array as a parameter in URL

I have an requirement to pass a some values from mobile to server in a web service call and so I am planning to pass all the values in JSON format like the below

{
    "nameservice": [
        {
            "id": 7413,
            "name": "ask"
        },
        {
            "id": 7414,
            "name": "josn"
        },
        {
            "id": 7415,
            "name": "john"
        },
        {
            "id": 7418,
            "name": "R&R"
        }
    ]
}

The following is my service call

@RequestMapping("/saveName")
@ResponseBody
public String saveName(String acc)
{jsonObject = new JSONObject();
    try
    {
    );
    System.out.println(acc);
    jsonObject.accumulate("result", "saved ");
    }
    catch(Exception e)
    {
        e.printStackTrace();jsonObject.accumulate("result", "Error Occured ");
    }
    return jsonObject.toString();
}

I am trying to call the above service by this way

localhost:8080/service/saveName?acc={ "nameservice": [ { "id": 7413, "name": "ask" }, { "id": 7414, "name": "josn" }, { "id": 7415, "name": "john" }, { "id": 7418, "name": "R&R" } ] }

But the output is like this

{ "nameservice": [ { "id": 7413, "name": "ask" }, { "id": 7414, "name": "josn" }, { "id": 7415, "name": "john" }, { "id": 7418, "name": "R

Can any body please tell me why I am not getting all the values please?

I would suggest to pass the JSON data in the body as a POST request.But if you still want to pass this as a parameter in URL,you will have to encode your URL like below just for example:-

for ex json is :->{"name":"ABC","id":"1"}

testurl:80/service?data=%7B%22name%22%3A%22ABC%22%2C%22id%22%3A%221%22%7D

for more information on URL encoding refer below

https://en.wikipedia.org/wiki/Percent-encoding

I know this could be a later post, but, for new visitors I will share my solution, as the OP was asking for a way to pass a JSON object via GET (not POST as suggested in other answers).

1. Take the JSON object and convert it to string (JSON.stringify)
2. Take the string and encode it in Base64 (you can find some useful info on this here
3. Append it to the URL and make the GET call
4. Reverse the process. decode and parse it into an object

I have used this in some cases where I only can do GET calls and it works. Also, this solution is practically cross language.

I know this is old, but if anyone else wants to know why they get incomplete json like above is because the ampersand & is a special character in URLs used to separate parameters.
In your data there is an ampersand in R&R. So the acc parameter ends when it reaches the ampersand character.

That's why you are getting chopped data. The solution is either url encode the data or send as POST like the accepted solution suggests.

You can pass your json Input as a POST request along with authorization header in this way

public static JSONObject getHttpConn(String json){
        JSONObject jsonObject=null;
        try {
            HttpPost httpPost=new HttpPost("http://google.com/");
            org.apache.http.client.HttpClient client = HttpClientBuilder.create().build();
            StringEntity stringEntity=new StringEntity("d="+json);

            httpPost.addHeader("content-type", "application/x-www-form-urlencoded");
            String authorization="test:test@123";
            String encodedAuth = "Basic " + Base64.encode(authorization.getBytes());        
            httpPost.addHeader("Authorization", security.get("Authorization"));
            httpPost.setEntity(stringEntity);
            HttpResponse reponse=client.execute(httpPost);
            InputStream inputStream=reponse.getEntity().getContent();
            String jsonResponse=IOUtils.toString(inputStream);
            jsonObject=JSONObject.fromObject(jsonResponse);
            } catch (UnsupportedEncodingException e) {

            e.printStackTrace();
        } catch (ClientProtocolException e) {

            e.printStackTrace();
        } catch (IOException e) {

            e.printStackTrace();
        }
        return jsonObject;


    }

This Method will return a json response.In same way you can use GET method
