直接上代码//预置属性varSECRET=“”;varSERVER_SECRET_KEY=‘’;varAPIKEY_KEY=‘apiKey’varapiKey=‘’;varseed=1234;varnonce=5678;//init接口插入全局变量apiKey其余拿if(pm.request.url.getPath()===‘/user/init’){apiKey=newDate().valueOf()pm.globals.set(APIKEY_KEY,apiKey);}else{apiKey=pm.globals.get(APIKEY_KEY);}//增加query参数pm.request.

我将Cygwin与GCC一起使用，最终我想将字rune件读入字符vector，并使用此代码#include#include#includeusingnamespacestd;intmain(intargc,char*argv[]){vectorstring1();string1.push_back('a');return0;}生成此编译时错误:main.cpp:Infunctionintmain(int,char**)':main.cpp:46:error:requestformemberpush_back'instring1',whichisofnon-classtypestd::v

根据thiswebsite，MPI::COMM_WORLD.Send(...)的用法是线程安全的。但是，在我的应用程序中，我经常(并非总是)遇到死锁或出现段错误。附上MPI::COMM_WORLD的每个电话带有mutex.lock()的方法和mutex.unlock()始终如一地消除死锁和段错误。这就是我创建线程的方式:constautocommunicator=std::make_shared();std::vector>handles;for(size_ti=0;iCommunicator是一个具有std::mutex的类成员并独占调用诸如MPI::COMM_WORLD.Send(
