京東支付Android接入說明文檔

1、根據(jù) 京東支付Android接入說明文檔 集成sdk依賴的jar包，配置相關(guān)的內(nèi)容（主要根據(jù)文檔一步一步配置就行，這里就不細(xì)說了，本章主要是關(guān)于使用RN調(diào)用sdk）

?

2、在../android/app/src/java 下面創(chuàng)建一個(gè)類實(shí)現(xiàn)接口 ReactPackage 包管理器，并把上面創(chuàng)建的類加到原生模塊（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", "支付結(jié)果：" + result);callback.invoke(result);}}}};@Overridepublic String getName() {return "JDPayModule";}@ReactMethodpublic void addEvent(ReadableMap payParams, Callback returnCallback) {Log.d("JD_PAY", "入?yún)?#xff1a;" + payParams.toString());JDPayAuthor jdPayAuthor = new JDPayAuthor();String extraInfo = "";//json數(shù)據(jù)格式，jdPayAuthor.author(ma, payParams.getString("orderId"), payParams.getString("merchant"), payParams.getString("appId"), payParams.getString("signData"), extraInfo);callback = returnCallback;}}

3、MainActivity里初始化一個(gè)頁面容器

?4、將創(chuàng)建的包管理器添加到 ReactPackage 列表中（getPackages 方法）

?

5、喚起京東支付 (jdpay接口需要生成一個(gè)京東訂單，返回商戶id、訂單id和京東支付MD5的密鑰)

MD5的密鑰需要通過MD5進(jìn)行加密生產(chǎn)簽名

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'});}});}}

?
