安卓HttpClient响应

3

我试图使用HttpClient从我的Android应用程序向php脚本发送json数据，并获取响应。

Android代码：

private void sendPurchase(String SKU) throws IOException{       
    Log.e("sendPurchase","Inside sendPurchase");
    final SharedPreferences prefs = getGCMPreferences(getApplicationContext());
    int pur_user = prefs.getInt("C_user", Integer.MIN_VALUE);
    InputStream inputStream = null;
    String result = "";
    HttpClient httpclient = new DefaultHttpClient(); 
    HttpPost httpPost = new HttpPost("http://www.*.com/includes/purchase.php");            
    JSONObject json = new JSONObject();            
    try {
        json.put("PUR_sku", SKU);
        json.put("PUR_user", pur_user);
    } catch (JSONException e) { Log.e("SendPurchase","Problem with Json Object"); }     
    Log.i("JSONObject", json.toString());
    StringEntity se = new StringEntity(json.toString(), HTTP.UTF_8);
    httpPost.setEntity(se);
    httpPost.setHeader("Accept", "application/json");
    httpPost.setHeader("Content-type", "application/json");          
    HttpResponse httpResponse = httpclient.execute(httpPost);
    inputStream = httpResponse.getEntity().getContent();
    if(inputStream != null){ result = convertInputStreamToString(inputStream); }
    else{result = "Did not work!"; }
    Log.e("RESULT",result);     
}

private static String convertInputStreamToString(InputStream inputStream) throws IOException{
    BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
    String line = "";
    String result = "";
    while((line = bufferedReader.readLine()) != null)
        result += line; 
    inputStream.close();
    return result; 
}

同时PHP脚本

<? 
$auth=0;
require('./connexion.php');
$data = file_get_contents('php://input');
//$data = '{"PUR_sku":"singleone","PUR_user":"3"}';
$json = json_decode($data,true);
/* Some database stuff ... */
echo "Retour ".print_r($json)." et ".$json['PUR_sku']." et ".$json['PUR_user'];
?>

当我启动应用程序并执行sendPurchase函数时，除了最后一个“RESULT”日志之外，logcat中的所有日志都显示正确的参数。因此，我认为HttpPost的执行出了问题，但实际上我不知道问题是来自应用程序方面还是php脚本方面... 当我在Web浏览器中单独执行php脚本，并将第一个$data行替换为第二个行时，一切都正常。但是当来自应用程序时就不正常了... 发送到脚本的Json对象（我希望）似乎也没问题：{"PUR_user":3,"PUR_sku":"singleone"}

（sendPurchase函数在后台执行）

有关我做错了什么的任何想法吗？谢谢！

这是@RyuZz解决方案的logcat。我的代码是关于购买物品，消耗它并将新值发送到我的Web服务器上的数据库。购买和消耗正常，但我无法将值发送到Web服务器。再次注意，我有另一个类似的代码用于向GCM注册用户，使用HttpClient，该代码运行良好。

您可以尝试以下替代方案，而不是已经被弃用的HttpClient：

您可以尝试使用以下替代方案，而不是已经被弃用的HttpClient：

try{
    int pur_user = prefs.getInt("C_user", Integer.MIN_VALUE);

    URL url = new URL("http://www.*.com/includes/purchase.php");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setDoOutput(true);
    connection.setDoInput(true);
    connection.setRequestProperty("Content-Type", "application/json");
    connection.setRequestProperty("Accept", "application/json");
    connection.setRequestMethod("POST");

    JSONObject jsonObject = new JSONObject();
    jsonObject.put("PUR_sku", SKU);
    jsonObject.put("PUR_user", pur_user);

    //convert JSONObject to JSON to String
    json = jsonObject.toString();

    OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
    writer.write(json);
    writer.close();

    responseCode = connection.getResponseCode();

    if(responseCode == 200) {

        InputStream content = connection.getInputStream();
        try {

            BufferedReader reader = new BufferedReader(new InputStreamReader(content, "UTF-8"), 8);
            StringBuilder sb = new StringBuilder();

            String line;
            while ((line = reader.readLine()) != null)
            {
                sb.append(line).append("\n");
            }
            result = sb.toString();

            //TODO get your stuff from result

            content.close();
        } catch (Exception ex) {
             Log.e(TAG, "Failed to parse JSON due to: " + ex);
        } finally {
             connection.disconnect();
        }
    } else {
        Log.e(TAG, "Server responded with status code: " + responseCode);
    }
} catch(Exception ex) {
    Log.e(TAG, "Failed to send HTTP POST request due to: " + ex);
}

如果这个方法不起作用，请发布logcat。
