POSTing JSON/XML using android-async-http (loopj)

Question

I am using android-async-http and really liking it. I\'ve run into a problem with POSTing data. I have to post data to the API in the following format: -

&l         


        

Answer 1

Just make JSONObject and then convert it to String "someData" and simply send with "ByteArrayEntity"

    private static AsyncHttpClient client = new AsyncHttpClient();
    String someData;
    ByteArrayEntity be = new ByteArrayEntity(someData.toString().getBytes());
    client.post(context, url, be, "application/json", responseHandler);

It is working fine for me.

Answer 2

just write your xml or json to a string and send to server, with proper headers or without. and yes set "Content-Type" to "application/json"

Answer 3

a better way to post json

RequestParams params = new RequestParams();
    params.put("id", propertyID);
    params.put("lt", newPoint.latitude);
    params.put("lg", newPoint.longitude);
    params.setUseJsonStreamer(true);

    ScaanRestClient restClient = new ScaanRestClient(getApplicationContext());
    restClient.post("/api-builtin/properties/v1.0/edit/location/", params, new AsyncHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
        }

        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
        }
    });

Answer 4

If someone have a problem that httpclient send as Content-Type: text/plain, please refer this link: https://stackoverflow.com/a/26425401/361100

The loopj httpclient is somewhat changed (or has problem) which cannot override StringEntity native Content-Type to application/json.

Answer 5

@Timothy answer did not work for me.

I defined the Content-Type of the StringEntity to make it work:

JSONObject jsonParams = new JSONObject();
jsonParams.put("notes", "Test api support");

StringEntity entity = new StringEntity(jsonParams.toString());
entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));

client.post(context, restApiUrl, entity, "application/json", responseHandler);

Good Luck :)

You can add the JSON string as an InputStream of some kind - I've used the ByteArrayStream, then passing it to the RequestParams you should set the correctMimeType

InputStream stream = new ByteArrayInputStream(jsonParams.toString().getBytes(Charset.forName("UTF-8")));
multiPartEntity.put("model", stream, "parameters", Constants.MIME_TYPE_JSON);
