京东支付IOS接入说明文档

1、根据 京东支付IOS接入说明文档 集成sdk依赖的framework，配置相关的内容（xcode 需要配置签名）

2、在ios 下封装调用sdk的方法

JDPayManager.h

//
//  JDPayManager.h

//#import <React/RCTBridgeModule.h>@interface JDPayManager : NSObject <RCTBridgeModule>
@end

 JDPayManager.m

.m文件是对.h文件中方法是实现，对外部是不可见的

//
//  JDPayManager.m

//#import <Foundation/Foundation.h>
#import "JDPayManager.h"
#import "ViewController.h"

{dispatch_async(dispatch_get_main_queue(), ^{UIViewController *weakSelfView = [self getCurrentVC];NSString *appId = [payReq objectForKey:@"appId"];NSString *merchant = [payReq objectForKey:@"merchant"];NSString *orderId = [payReq objectForKey:@"orderId"];NSString *signData = [payReq objectForKey:@"signData"];NSLog(@"京东支付");[JDPayAuth_mainModule() payWithViewController:weakSelfViewappID:appIdmerchant:merchantorderId:orderIdsignData:signDataextraInfo:nilcompletion:^(NSDictionary *resultDict) {NSLog(@"支付结果");NSLog(@"京东 result = %@",resultDict);callback(@[resultDict]);}];});
}
- (UIViewController *)getCurrentVC
{UIViewController * curVC = nil;UIWindow * window = [[UIApplication sharedApplication] keyWindow];if (window.windowLevel != UIWindowLevelNormal){NSArray *windows = [[UIApplication sharedApplication] windows];for(UIWindow * tmpWin in windows){if (tmpWin.windowLevel == UIWindowLevelNormal){window = tmpWin;break;}}}UIView *frontView = [[window subviews] objectAtIndex:0];id nextResponder = [frontView nextResponder];if ([nextResponder isKindOfClass:[UIViewController class]]){curVC = nextResponder;}else{UIViewController * appRootVC = window.rootViewController;UIViewController * topVC = appRootVC;curVC = topVC;if (topVC.presentedViewController){curVC = topVC.presentedViewController;}}return curVC;
}@end

 AppDelegate.m

#pragma mark - Handle url
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(nullable NSString *)sourceApplication annotation:(id)annotation
{NSMutableDictionary *options = [NSMutableDictionary dictionaryWithCapacity:2];if (sourceApplication != nil) {options[UIApplicationOpenURLOptionsSourceApplicationKey] = sourceApplication;}if (annotation != nil) {options[UIApplicationOpenURLOptionsAnnotationKey] = annotation;}return [self application:application openURL:url options:options];
}- (BOOL)application:(UIApplication *)appopenURL:(NSURL *)urloptions:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{if ([JDPayModule canHandleURL:url options:options]) {[JDPayModule handleURL:urloptions:optionscompletionHandler:^(NSDictionary * __nullable results, BOOL handled) {NSLog(@"handleURL:%@ options:%@ completionHandler:(%@, %@)",url, options, results, handled ? @"YES" : @"NO");}];return YES;}return NO;
}

3、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 === 'ios') {JDPayModule = NativeModules.JDPayManager;JDPayModule.addEvent(payRequest, (result) => {console.log('result====>', result);if (result.payStatus == 'JDP_PAY_SUCCESS') {msg.emit('router: goToNext', {routeName: 'PaySuccess',tid: tid,payType: 'online'});}});}
