iOS内购坑（Ruby服务器验证）

iOS端

- (void)verifyPurchaseWithPaymentTransactionSuccess:(void(^)(NSString *success))successBlock

failure:(void(^)(NSString *error))failureBlock{

NSString *urlStr = @"/appstorepay/receiptdata";
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];

NSDictionary *requestContents = @{
@"receipt_data": [receipt base64EncodedStringWithOptions:0],
//  @"XDEBUG_SESSION_START":@"12477"
};
[NetworkingUtil postWithUrlString:urlStr parameters:requestContents success:^(NSDictionary *data) {
successBlock(data[@"msg"]);
} failure:^(NSError *error) {
failureBlock([NSString stringWithFormat:@"验证购买过程中发生错误, 错误信息：%@",error.localizedDescription]);
}];

}

因为不懂Ruby，公司又没Ruby技术员，只能自己瞎蒙，代码功能是实现了，但是总感觉哪里写得有问题，如果有朋友会，希望能指出（Ruby的坑太深了T.T）
