京东支付Android接入说明文档

1、根据 京东支付Android接入说明文档 集成sdk依赖的jar包，配置相关的内容（主要根据文档一步一步配置就行，这里就不细说了，本章主要是关于使用RN调用sdk）

 

2、在../android/app/src/java 下面创建一个类实现接口 ReactPackage 包管理器，并把上面创建的类加到原生模块（NativeModule）列表中

JDPayPackage.java

import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.uimanager.ViewManager;import java.util.ArrayList;
import java.util.Collections;
import java.util.List;public class JDPayPackage implements ReactPackage {@Overridepublic List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {return Collections.emptyList();}@Overridepublic List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {List<NativeModule> modules = new ArrayList<>();modules.add(new JDPayModule(reactContext));return modules;}}

JDPayModule.java

import android.app.Activity;
import android.content.Intent;
import android.util.Log;import com.facebook.react.bridge.ActivityEventListener;
import com.facebook.react.bridge.BaseActivityEventListener;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.bridge.ReactContextBaseJavaModule;
import com.facebook.react.bridge.ReactMethod;
import com.facebook.react.bridge.ReadableMap;
import com.facebook.react.bridge.Callback;
import com.jdpaysdk.author.Constants;
import com.jdpaysdk.author.JDPayAuthor;public class JDPayModule extends ReactContextBaseJavaModule{private static Activity ma;private static Callback callback;public static void initSocialSDK(Activity activity){ma = activity;}public JDPayModule(ReactApplicationContext reactContext) {super(reactContext);reactContext.addActivityEventListener(mActivityEventListener);}private final ActivityEventListener mActivityEventListener = new BaseActivityEventListener() {@Overridepublic void onActivityResult(Activity activity, int requestCode, int resultCode, Intent data) {if(data != null){if (Constants.PAY_RESPONSE_CODE == resultCode) {//返回信息接收String result = data.getStringExtra(JDPayAuthor.JDPAY_RESULT);Log.d("JD_PAY", "支付结果：" + result);callback.invoke(result);}}}};@Overridepublic String getName() {return "JDPayModule";}@ReactMethodpublic void addEvent(ReadableMap payParams, Callback returnCallback) {Log.d("JD_PAY", "入参：" + payParams.toString());JDPayAuthor jdPayAuthor = new JDPayAuthor();String extraInfo = "";//json数据格式，jdPayAuthor.author(ma, payParams.getString("orderId"), payParams.getString("merchant"), payParams.getString("appId"), payParams.getString("signData"), extraInfo);callback = returnCallback;}}

3、MainActivity里初始化一个页面容器

 4、将创建的包管理器添加到 ReactPackage 列表中（getPackages 方法）

 

5、唤起京东支付 (jdpay接口需要生成一个京东订单，返回商户id、订单id和京东支付MD5的密钥)

MD5的密钥需要通过MD5进行加密生产签名

   const { code, context, message } = await webapi.jdpay(tid);if (code == config.SUCCESS_CODE) {const text ='merchant=' +context.merchant +'&orderId=' +context.orderId +'&key=' +Const.MD5_KET;const signData = MD5.hex_md5(text).toLowerCase();const payRequest = {orderId: context.orderId,merchant: context.merchant,appId: Const.APP_ID,signData: signData};let JDPayModule;if (Platform.OS === 'Android') {JDPayModule = NativeModules.JDPayModule;JDPayModule.addEvent(payRequest, (result) => {console.log('result====>', result);if (JSON.parse(result).payStatus == 'JDP_PAY_SUCCESS') {msg.emit('router: goToNext', {routeName: 'PaySuccess',tid: tid,payType: 'online'});}});}}
