在我们的App中是很经常的会用到微信的两个功能，1就是分享，2就是支付（通常会和支付宝、银联支付放在一起使用),通常接入这种三方的东西，对于移动端来说，过程都比较简单，但是对于后台来说，一般也不是说难，就是步骤多，配置的东西比移动端多（像比如支付过程）, 废话不多说，由于我这里的分享只需要做微信的分享，所以过程比较简单，配置什么的就不多说了，自己去看微信支付的UML流程图和微信SDK的配置流程，对于iOS端的代码如下:
首先在工程里面配置白名单：

AppDelegate里面初始化微信SDK：
[WXApi registerApp:kWeChatID];
支付or分享代码：
[ShareView shareViewWithCompleteHandel:^(NSInteger index) {
WXMediaMessage * message = [WXMediaMessage message];
message.title = [NSString stringWithFormat:@"%@[%@k-%@k]",rel[@"job_name"],rel[@"salary_min"],rel[@"salary_max"]];
message.description = [NSString stringWithFormat:@"入职快,加薪快,还能赚外快\n%@",rel[@"com_name"]];
[message setThumbImage:image];
WXWebpageObject * webpageObject = [WXWebpageObject object];
webpageObject.webpageUrl = urlString;
message.mediaObject = webpageObject;
SendMessageToWXReq * req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.message = message;
req.scene = index == 0 ? WXSceneSession :index == 1 ? WXSceneTimeline:WXSceneFavorite;
[WXApi sendReq:req];
}];
// 支付，note：这里的repsonse是后台生成的支付参数，下订单是请求自己的服务端拿到这些参数：
if ([responese isKindOfClass:[NSDictionary class]]) {
NSDictionary *payParams = (NSDictionary *)responese;
PayReq * req = [[PayReq alloc] init];
req.partnerId = payParams[@"partnerid"];
req.prepayId = payParams[@"prepayid"];
req.nonceStr = payParams[@"noncestr"];
req.timeStamp = [payParams[@"timestamp"] intValue];
req.package = payParams[@"package"];
req.sign = payParams[@"sign"];
[WXApi sendReq:req];
}
支付or分享结果的回调：
// MARK: - 处理三方回调
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options {
//判断是微信还是支付宝操作
if ([url.absoluteString rangeOfString:kWeChatID].location != NSNotFound){
return [WXApi handleOpenURL:url delegate:self];
} else {
if ([url.host isEqualToString:@"safepay"]) {
//支付宝支付回调自己App的结果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
return YES;
}
}
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
if ([url.absoluteString rangeOfString:kWeChatID].location != NSNotFound) {
return [WXApi handleOpenURL:url delegate:self];
} else if ([url.host isEqualToString:@"safepay"]) {
[[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
return YES;
}
// MARK: - WXApiDelegate
- (void)onResp:(BaseResp *)resp {
if ([resp isKindOfClass:[PayResp class]]){
//支付
PayResp *response = (PayResp*)resp;
switch(response.errCode){
case 0:
//服务器端查询支付通知或查询API返回的结果再提示成功
[[NSNotificationCenter defaultCenter] postNotificationName:kWeChatPaySucessNotificationName object:self userInfo:@{@"PayResp":resp}];
[_window.rootViewController alertWithTitle:@"支付成功!" complete:nil];
break;
case -1:
case -2: {
[_window.rootViewController alertWithTitle:@"支付失败!" complete:nil];
}
break;
default:
NSLog(@"支付失败，retcode=%d",resp.errCode);
break;
}
} else if ([resp isKindOfClass:[SendMessageToWXResp class]]) {
//分享
SendMessageToWXResp *sendMessageRes = (SendMessageToWXResp *)resp;
if (sendMessageRes.errCode == 0 ) {
[_window.rootViewController alertWithTitle:@"分享成功!" complete:nil];
} else if (sendMessageRes.errCode == WXErrCodeUserCancel) {
[_window.rootViewController alertWithTitle:@"您取消了分享!" complete:nil];
} else {
[_window.rootViewController alertWithTitle:@"分享失败!" complete:nil];
}
}
}
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
if ([url.host isEqualToString:@"safepay"]) {
//跳转支付宝钱包进行支付，处理支付结果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
return YES;
}
集成起来比较简单，由于这里的支付请求加密参数是放在后台进行的（也理论上是后台做比较安全，为了防止反编译，一般是后台做）App端做的事情相对来来说还是比较少的。
