Request

RpcRequest测试：

#include "message.hpp"using namespace bitrpc;int main()
{RpcRequest::ptr rrp = MessageFactory::create<RpcRequest>();Json::Value param;param["num1"] = 11;param["num2"] = 22;rrp->setMethod("Add");rrp->setParams(param);std::string ret = rrp->serialize();std::cout << ret << std::endl;//BaseMessage::ptr bmp = MessageFactory::create(MType::REQ_RPC);bool res = bmp->unserialize(ret);if(bmp->check() == false){return -1;}//!!!!!!! dynamic_pointer_cast的使用RpcRequest::ptr rrp2 = std::dynamic_pointer_cast<RpcRequest>(bmp);std::cout << rrp2->method() << std::endl;std::cout << rrp2->params()["num1"] << std::endl;std::cout << rrp2->params()["num2"] << std::endl;return 0;
}

运行：

⭕ debug_1:dynamic_pointer_cast

📒dynamic_cast 和 dynamic_Pointer_cast的使用

1.指引或者引用的向上转换，向下转换

例如基类A ，派生类B.。A->B 则为向下转换。。B->A则为向上转换。。向上转换为隐士转换。向下转换需要dynamic_cast或者c的转换方式。

B * b = new B;

A * a = b;

此时b就是向上转换。无需显式转换既可以编译通过。

2.dynamic_cast

一般用于有继承关系的类之间的向下转换。

3.dynamic_pointer_cast

当指针是智能指针时候，向下转换，用dynamic_Cast 则编译不能通过，此时需要使用dynamic_pointer_cast。

TopicRequest测试

int main()
{TopicRequest::ptr trp = MessageFactory::create<TopicRequest>();trp->setTopicKey("news");trp->setOptype(TopicOptype::TOPIC_PUBLISH);trp->setTopicMsg("hello world");std::string str = trp->serialize();std::cout << str << std::endl;BaseMessage::ptr bmp = MessageFactory::create(MType::REQ_TOPIC);bmp->unserialize(str);bool ret = bmp->check();TopicRequest::ptr trp2 = std::dynamic_pointer_cast<TopicRequest>(bmp);std::cout << trp2->topicKey() << std::endl;std::cout << (int)trp2->optype() << std::endl;std::cout << trp2->topicMsg() << std::endl;return 0;
}

ServiceRequest测试

int main()
{ServiceRequest::ptr trp = MessageFactory::create<ServiceRequest>();trp->setMethod("Add");trp->setOptype(ServiceOptype::SERVICE_REGISTRY);
//服务注册 测试trp->setHost(Address("127.0.0.1", 8080));std::string str = trp->serialize();std::cout << str << std::endl;BaseMessage::ptr bmp = MessageFactory::create(MType::REQ_SERVICE);bmp->unserialize(str);bool ret = bmp->check();ServiceRequest::ptr trp2 = std::dynamic_pointer_cast<ServiceRequest>(bmp);std::cout << trp2->method() << std::endl;std::cout << (int)trp2->optype() << std::endl;std::cout << trp2->host().first << std::endl;std::cout << trp2->host().second << std::endl;return 0;
}

⭕debug_2：gdb

调试：

使用 gdb

(gdb) break message.hpp:169
run

gdb 调试中 不能使用宏 !!!!!!!!!!!!!!!!!!!!

后续采用 p 打印查看
