内购流程以及要注意的地方

前言

一. 票据验证

1. APP 端票据验证

代码：

/**
 APP端 内购票据验证
 */
+ (void)ls_appCheckReceipt:(NSString *)receipt
                   success:(SuccessBlock)success
                   failure:(FailureBlock)failure {

    if (receipt == nil) {
        return;
    }

    // 获取票据信息
    NSError *error;
    NSDictionary *receiptDict = @{@"receipt-data": receipt};
    NSData *params = [NSJSONSerialization dataWithJSONObject:receiptDict options:0 error:&error];

    if (params == nil) {
        return;
    }

    // 沙盒验证
    NSURL *storeUrl = [NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"];
    NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:storeUrl];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:params];

    NSOperationQueue *queque = [[NSOperationQueue alloc] init];
    [NSURLConnection sendAsynchronousRequest:request queue:queque completionHandler:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {

        if (connectionError) {
            if (error) {
                failure(connectionError);
            }
        }else {
            NSError *error;
            NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
            if (!jsonResponse) {
                if (error) {
                    failure(error);
                }
            }else {
                if (success) {
                    LSSuccessInfo *info = [[LSSuccessInfo alloc] init];
                    info.response = jsonResponse;
                    success(info);
                }
            }
        }
    }];
}
