解析数据org.json.JSONException时出错：在字符0的输入结束

完成！！！在将POST将String数组传递给PHP之后，我得到了答案。

public JSonObject orderDetails(String username, String[] pid, String[] products,    String[] quantity, String[] totalprice, String finalprice) {// Building ParametersList params = new ArrayList();params.add(new BasicNamevaluePair("tag", order_tag));params.add(new BasicNamevaluePair("username", username));params.add(new BasicNamevaluePair("finalpice", finalprice));for (int i = 0; i < pid.length; i++) {    params.add(new BasicNamevaluePair("pid[]", pid[i]));}   for (int j = 0; j < products.length; j++) {    params.add(new BasicNamevaluePair("products[]", products[j]));}for (int k = 0; k < quantity.length; k++) {    params.add(new BasicNamevaluePair("quantity[]", quantity[k]));}for (int l = 0; l < totalprice.length; l++) {    params.add(new BasicNamevaluePair("totalprice[]", totalprice[l]));}JSonObject json = jsonParser.getJSonFromUrl(orderURL,params);return json;}
