java - HttpPost 响应不返回 json 对象

Question

我目前正在做一个项目，它需要发送一个 post 请求并从服务器获取一个 json 对象。之前我使用 Get 方法访问 json 对象。它运作良好。但是由于一些服务器更改，我不得不转向发布方法。然后它不会返回我之前从“get”方法获得的 json 对象。我尽力想出一个解决方案，但没有成功。如果有人能帮助我解决这个问题，我将不胜感激。

private AdSniperAdObjectResponse postData(String url) {
    //Bundle b = new Bundle();
    HttpClient httpClient = HttpClientFactory.getThreadSafeClient();
    //Log.d(TAG, "url: " + url);
    try {
        HttpPost httpPost = new HttpPost(url);
        httpPost.setHeader("Content-Type", "application/json");
        httpPost.setHeader("Accept", "JSON");


        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
        nameValuePairs.add(new BasicNameValuePair("latitude", "-33.8736"));
        nameValuePairs.add(new BasicNameValuePair("longitude", "151.207"));
        nameValuePairs.add(new BasicNameValuePair("age", "35"));
        nameValuePairs.add(new BasicNameValuePair("gender", "All"));

        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity resEntity = httpResponse.getEntity();
        if (resEntity != null) {
            String resp = EntityUtils.toString(resEntity);

以上是我使用的代码。早些时候我使用了 HttpGet 类。对于 HttpPost，“resp”变量始终为空。不知道我做错了什么。

这不应该是这样吗

HttpResponse httpResponse = httpClient.execute(httpPost);

        if (httpResponse  != null) {
            String resp = httpResponse.toString();

如果服务器返回 JSONString..

say JSONObject data = new JSONObject(resp);

然后获取值..
