性能测试工具 loadrunner 回调函数处理问题

loadrunner 中回调函数是否可用?

最近在测试 一个 c++ 封装的 dll 时,然后自己使用 c 包了一层,准备使用 lr 进行测试。但是 lr 在处理回调时报错。注册回调函数与我测试代码里面一样的,不清楚为啥会报错。

报错信息

报错位置 TdInit(api);此时会回调 TdRegisterCallback 中的 OnFrontEvent

mdrv.exe caused an EXCEPTION_ACCESS_VIOLATION in module <UNKNOWN> at 0023:000000A0

EAX=000000A0  EBX=03E025D0  ECX=005DF800  EDX=005DF800  ESI=046BFAD0

CS=0023   DS=002B  SS=002B  ES=002B   FS=0053  GS=002B

lr 中函数如下:

#include "USTPFtdcUserApiStruct.h"
#include "lrs.h"






void  OnFrontEvent(void* pObject, int type, int Reason) {
    printf("%s","connected!\n");
}
void  OnRspEvent(void* pObject, int type, void* pParam, void* pRspInfo, int nRequestID, int bIsLast) {
    printf("%s","rsp\n");
}
void  OnRtnEvent(void* pObject, int type, void* pParam) {
    printf("%s","rtn\n");
}
void  OnErrRtnEvent(void* pObject, int type, void* pParam, void* pRspInfo) {
    printf("%s","errRtn\n");
}

void  OnPackageEvent(void* pObject, int type, int nTopicID, int nSequenceNo) {
    printf("%s","OnPackageEvent");
}

vuser_init()
{



    void *api;
    char * frontip="tcp://192.168.133.41:43613";
    char * QryFrontIp="tcp://192.168.133.41:43618";
    char *pszReqLogFileName="reqlog";
    char *pszRspLogFileName="rsplog";

    void *pobject;
    //OnErrRtnEvent c1=mOnErrRtnEvent;
    //OnPackageEvent c3=NULL;
    //OnFrontEvent  c2=mOnFrontEvent;
    //OnRspEvent    c4=mOnRspEvent;
    //OnRtnEvent    c5=mOnRtnEvent;
    // 

   struct CUstpFtdcReqUserLoginField userfield;










     strcpy(userfield.BrokerID, "0001");
     strcpy(userfield.UserID, "1000004");
     strcpy(userfield.Password, "111111");
     strcpy(userfield.TradingDay, "20180305");


    lr_load_dll("ftdc2c_femas.dll");

    api=(void* )TdCreateFtdcTraderApi("");
    TdSubscribePrivateTopic(api,1);
    TdSubscribePublicTopic(api,1);
    TdSubscribeUserTopic(api,1);

    TdRegisterFront(api,frontip);
    TdRegisterQryFront(api,QryFrontIp);
    ////


    ///
    TdRegisterCallback(api,OnErrRtnEvent,OnFrontEvent,OnPackageEvent,OnRspEvent,OnRtnEvent,api);

    TdInit(api);
   lr_think_time(10);
   sleep(10);
   TdOpenRequestLog(api,pszReqLogFileName);
   TdOpenResponseLog(api,pszRspLogFileName);




    lr_think_time(30);

    TdReqUserLogin(api,&userfield,1);
    //TdDestroyApi(api);



    return 0;
}



其中报错地方为 TdInit(api),该处会有回调函数调用,回调函数注册 TdRegisterCallback(api,OnErrRtnEvent,OnFrontEvent,OnPackageEvent,OnRspEvent,OnRtnEvent,api);

按我的经验 LR 是无法处理回调的,不知道理解是否有误,还要其他人帮忙确认下。
