使用android-async-http(loopj)发布JSON/XML

Question

我正在使用android-async-http而且非常喜欢它.我遇到了POST数据的问题.我必须以下列格式将数据发布到API: -

<request>
  <notes>Test api support</notes>
  <hours>3</hours>
  <project_id type="integer">3</project_id>
  <task_id type="integer">14</task_id>
  <spent_at type="date">Tue, 17 Oct 2006</spent_at>
</request>

根据文档,我尝试使用它RequestParams,但它失败了.这是其他任何方式吗？我也可以发布等效的JSON.有任何想法吗？

Answer 1

Loopj POST示例 - 从他们的Twitter示例扩展:

private static AsyncHttpClient client = new AsyncHttpClient();

通过RequestParams以下方式发布:

RequestParams params = new RequestParams();
params.put("notes", "Test api support"); 
client.post(restApiUrl, params, responseHandler);

要发布JSON:

JSONObject jsonParams = new JSONObject();
jsonParams.put("notes", "Test api support");
StringEntity entity = new StringEntity(jsonParams.toString());
client.post(context, restApiUrl, entity, "application/json",
    responseHandler);

Answer 2

@Timothy的回答对我不起作用.

我定义Content-Type的StringEntity,使其工作:

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);

祝好运 :)

发布json的更好方法

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) {
        }
    });
