Faster JsonCpp alternative that allows copying/mutability of Json objects?

问题 JsonCpp is slow. And the code is pretty messy. Is there any alternative that is faster, cleaner and supports stuff like: Json::Value val, copy; val["newMember"] = 100; val["newMember2"] = "hello"; copy = val; val["newMember2"] = "bye"; assert(val["newMember"] == copy["newMember"]); assert(val["newMember2"] != copy["newMember2"]); JsonCpp supports code like the one above. I've tried rapidjson , which is very fast, but unfortunately it does not support copying Json values. Any alternative?

问题 I'm trying to extract the key and the value of an object in array but don't find the proper getter: for (Value::ConstValueIterator itr = document["params"].Begin(); itr != document["params"].End(); ++itr) { for (Value::MemberIterator m = itr->MemberBegin(); m != itr->.MemberEnd(); ++m) { } } in the second loop, I want to extract the key and value from the iterator separately. how to do the extraction? 回答1: Suppose V is a JSON object which has key-value object. You can retrieve data like this.

短信验证码接入----腾讯云

最近因为公司项目需要接入短信验证码功能,在网上转了几圈,最终选定了2家公司;一家是腾讯云的短信业务,这个是收费的。另一个是Mob的短信业务,这个是免费的。 本篇文章主要是介绍腾讯云的接入,后面一章节会介绍Mob的接入方法。 腾讯云的接入文档参考地址: https://cloud.tencent.com/document/product/382/5976 参数问题和错误码等直接看文档,下面我们说说流程。 首先是需要去腾讯云注册账号,然后做个人或者公司的实名认证。通过之后再注册应用,应用也是需要通过认证来申请短信模板的; 注册地址如下: https://console.cloud.tencent.com/sms/smslist 创建应用之后如下: https://console.cloud.tencent.com/sms/smsinfo/1400248333/0 这里是应用的管理后台,可以查看很多信息。管理短信模板等。一样的是ID和key: 验证流程是,手机端生成验证码,并本地保存,好后面做验证;然后把手机号和验证码通过Http的json格式的数据发生给TX,TX校验通过之后,会把验证码发给对应手机号。TX本身是不生成验证码和做校验的。验证码生成和校验都是需要我们自己做的。手机端收到验证码之后,和之前的缓存做对比,本地判断是否验证成功。TX的作用就是一个短信息的发送
