【问题描述】：
我正在尝试根据此链接“https://developer.paytm.com/docs/v1/android-sdk/”实施 Paytm 网关，但在应用程序 webview 中打开，我卡在 Paytms 处理页面。下面是我用来尝试的演示代码。请帮忙，因为 Paytm 没有帮助。我没有遗漏任何参数，因为如果我删除/更改任何参数，它会在特定参数处显示错误。 首先，我在服务器上创建一个订单 ID，然后校验和然后调用 Paytm 服务。 使用相同校验和的同一件事在 PC 浏览器上运行，但在 android 上运行。
public class MainActivity extends AppCompatActivity {
APIinterface apiInterface;
String order_id,paytmschecksum;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_SMS, Manifest.permission.RECEIVE_SMS}, 101);
}
get_orderid();
}
public void get_orderid(){
apiInterface = APIClient.getClient().create(APIinterface.class);
Call<List<OrderID_response>> call = apiInterface.get_orderid("1","rxazcv89315285244163");
call.enqueue(new Callback<List<OrderID_response>>() {
@Override
public void onResponse(Call<List<OrderID_response>> call, Response<List<OrderID_response>> response) {
// Toast.makeText(LocationUpdateService.this, response.toString(), Toast.LENGTH_SHORT).show();
List<OrderID_response> details = response.body();
if(details!=null){
if(details.get(0).getResponse().equalsIgnoreCase("success")){
order_id = details.get(0).getUnique_id();
Log.d("Order Id :", order_id );
get_paytmchecksum();
}
}
}
@Override
public void onFailure(Call<List<OrderID_response>> call, Throwable t) {
Toast.makeText(MainActivity.this, "Failure:" +t, Toast.LENGTH_SHORT).show();
Log.d(TAG, "onFailure: "+t.toString());
