Question

我尝试与一个Android应用程序集成payUMoney。我在互联网上搜索了很多东西，但我找不到任何解决方案。

有人可以建议我如何在我的Android应用程序中集成payUMoney吗？

Answer 1

来自前端的PayU集成部分：

String postData = "firstname=" + firstname + "&lastname=" + ""
                            + "&surl=" + sucess_url + "&phone=" + phone
                            + "&key=" + key + "&hash=" + hash + "&curl=" + ""
                            + "&furl=" + failure_url + "&txnid=" + txnid
                            + "&productinfo=" + productinfo + "&amount="
                            + amount + "&email=" + email + "&pg="
                            + "CC" + "&drop_category="
                            + "NB";



browser.getSettings().setLoadsImagesAutomatically(true);

browser.getSettings().setJavaScriptEnabled(true);

browser.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

browser.postUrl(action,EncodingUtils.getBytes(postData, "base64"));

请查看this link了解详情。

pg =您希望在PayUMoney上打开哪个标签

（例如：NB =网上银行，CC =信用卡，DC =借记卡和EMI）

drop_category =以逗号分隔的付款选项列表，从付款页面中删除。例如，CC。 NB丢弃信用卡和网上银行选项，仅显示借记卡选项。
