Wechat Pay
//1.create request for wechat pay
WechatPayReq wechatPayReq = new WechatPayReq.Builder()
.with(this) //activity instance
.setAppId(appid) //wechat pay AppID
.setPartnerId(partnerid)//wechat pay partner id
.setPrepayId(prepayid)//pre pay id
// .setPackageValue(wechatPayReq.get)//"Sign=WXPay"
.setNonceStr(noncestr)
.setTimeStamp(timestamp)//time stamp
.setSign(sign)//sign
.create();
//2. send the request with wechat pay
PayAPI.getInstance().sendPayRequest(wechatPayReq);
//set the callback for wechat pay
//wechatPayReq.setOnWechatPayListener(new OnWechatPayListener);
Notes：WechatPayReq have no method to set the money, because the money info is include in the parameter 'prepayid'.
Ali Pay
First way(Not Recommend, and its partner rsa private key export in the client , it is very dangerous!)
//step 1 create config for ali pay
AliPayAPI.Config config = new AliPayAPI.Config.Builder()
.setRsaPrivate(rsa_private) // rsa private key from partner (pkcs8 format)
.setRsaPublic(rsa_public)//ali rsa public key
.setPartner(partner) //set partner
.setSeller(seller) //set partner seller accout
.create();
//step 2 create reqeust for ali
AliPayReq aliPayReq = new AliPayReq.Builder()
.with(activity)//Activity instance
.apply(config)// the above custome config
.setOutTradeNo(outTradeNo)//set unique trade no
.setPrice(price)//set price
.setSubject(orderSubject)//set order subject
.setBody(orderBody)//set order detail
.setCallbackUrl(callbackUrl)//set callback for pay reqest
.create()//
.setOnAliPayListener(null);//
//step 3 send the request for ali pay
PayAPI.getInstance().sendPayRequest(aliPayReq);
// set the ali pay callback
//aliPayReq.setOnAliPayListener(new OnAliPayListener);
Second way(Highly Recommend)
//step 1 create raw ali pay order info
String rawAliOrderInfo = new AliPayReq2.AliOrderInfo()
.setPartner(partner) //set partner
.setSeller(seller) //set partner seller accout
.setOutTradeNo(outTradeNo) //set unique trade no
.setSubject(orderSubject) //set order subject
.setBody(orderBody) //set order detail
.setPrice(price) //set price
.setCallbackUrl(callbackUrl) //set callback for pay reqest
.createOrderInfo(); //create ali pay order info
//step 2 get the signed ali pay order info
String signAliOrderInfo = getSignAliOrderInfoFromServer(rawAliOrderInfo);
//step 3 step 3 send the request for ali pay
AliPayReq2 aliPayReq = new AliPayReq2.Builder()
.with(activity)//Activity instance
.setSignedAliPayOrderInfo(signAliOrderInfo)
.setRawAliPayOrderInfo(rawAliOrderInfo)//set the ali pay order info
.setSignedAliPayOrderInfo(signAliOrderInfo) //set the signed ali pay order info
.create()//
.setOnAliPayListener(null);//
PayAPI.getInstance().sendPayRequest(aliPayReq);
//set the ali pay callback
//aliPayReq.setOnAliPayListener(new OnAliPayListener);
ISSUE
About Wechat Pay Callback
How to do ：
1.new folder named 'wxapi' under your project root package
2.and create class WXPayEntryActivity under the wxapi
3.implements IWXAPIEventHandler interface
The sample as follow：
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;
import com.tencent.mm.sdk.constants.ConstantsAPI;
import com.tencent.mm.sdk.modelbase.BaseReq;
import com.tencent.mm.sdk.modelbase.BaseResp;
import com.tencent.mm.sdk.openapi.IWXAPI;
import com.tencent.mm.sdk.openapi.IWXAPIEventHandler;
import com.tencent.mm.sdk.openapi.WXAPIFactory;
public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler{
private static final String TAG = "MicroMsg.SDKSample.WXPayEntryActivity";
private IWXAPI api;
//TODO need to replace your APP_ID
private String APP_ID = "wx0xxxxxxxxx"; //need to replace your APP_ID
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.pay_result);
api = WXAPIFactory.createWXAPI(this, APP_ID);
api.handleIntent(getIntent(), this);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
api.handleIntent(intent, this);
}
@Override
public void onReq(BaseReq req) {
}
@Override
public void onResp(BaseResp resp) {
Log.d(TAG, "onPayFinish, errCode = " + resp.errCode);
if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {
// AlertDialog.Builder builder = new AlertDialog.Builder(this);
// builder.setTitle(R.string.app_tip);
// builder.setMessage(getString(R.string.pay_result_callback_msg, String.valueOf(resp.errCode)));
// builder.show();
//send the wechat pay broadcast receiver，and you should the define wechat pay broadcast receive
Intent intent = new Intent();
intent.setAction(WeChatPayReceiver.ACTION_PAY_RESULT);
intent.putExtra("result", resp.errCode);
sendBroadcast(intent);
finish();
}
}
}
