c). 同步发送, 等待响应, 超时后收到1个系统消息.
贴上代码
#include <iostream>
#include "caf/all.hpp"
#include "caf/io/all.hpp"
#include <string>
#include <thread>
#include <chrono>
#include <unistd.h>
using namespace std;
using namespace caf; behavior fun(event_based_actor* self){
return {
[self](const string& str, const actor &buddy)->string {
aout(self)<<str<<endl;
//self->delayed_send(buddy,std::chrono::milliseconds(10),"I'm lated");
//std::this_thread::sleep_for(std::chrono::seconds(1));
//usleep(10000);
while();
return "log";
self->quit();
}
};
} void fun1(event_based_actor* self, const actor &buddy){
self->sync_send(buddy,"hi!",self).then(
[=](const string& str) {
aout(self)<<str<<endl;
},
after(std::chrono::milliseconds())>>[&](){
aout(self)<<"timeout!"<<endl;
}
);
aout(self)<<"i'm not waiting for you!"<<endl;
} int main(){
auto actor1 = spawn(fun);
auto actor2 = spawn(fun1,actor1);
caf::await_all_actors_done();
shutdown();
return ;
}
其中自己试了几种线程休息的几种方法,发现usleep和 C++11自己提供的线程休眠库会导致coredump并且输出一堆东西,可能是caf自己的东西没有去深究等,
还有就是delay_send我也一开始有点傻,想用delay_send去回复发过来的消息,所以传入了actor,但是要搞清楚“发送”和“回复”是两种东西,你不能用发送来回复,只能用return来回复
d). 同步发送, 同步等待. 适用阻塞的actor api.
#include <iostream>
#include "caf/all.hpp"
#include "caf/io/all.hpp"
#include <string>
#include <chrono>
using namespace std;
using namespace caf; behavior fun(event_based_actor* self){
return {
[self](const string& str)->string {
aout(self)<<str<<endl;
return "I got it.";
//self->quit();
}
};
} void fun1(blocking_actor* self, actor buddy){
self->sync_send(buddy,"hi!").await(
[=](const string& str) {
aout(self)<<str<<endl;
},
after(std::chrono::milliseconds())>>[&](){
aout(self)<<"timeout!"<<endl;
}
);
aout(self)<<"i'm not waiting for you!"<<endl;
} int main(){
auto actor1 = spawn(fun);
auto actor2 = spawn<blocking_api>(fun1,actor1);
caf::await_all_actors_done();
shutdown();
return ;
}
结果(顺序变了)为
唯一修改就是spawn那边加上类型。
自己写了一个很简陋的聊天 传文件的程序,有兴趣可以看一下,维护好友列表,心跳机制都是用caf实现,当时没有用caf的序列话 用的是boost库的。
