LoadRunner中自定义C函数实现字符串替换
1.在globals.h 中定义一个函数ReplaceStr,实现字符串的替换:
int ReplaceStr(char* sSrc, char* sMatchStr, char* sReplaceStr)
{
int StringLen;
char caNewString[1024];
char* findPos;
merc_timer_handle_t timer_ReplaceStr = lr_start_timer();
lr_debug_message(LR_MSG_CLASS_EXTENDED_LOG ,"Notify:Function 'ReplaceStr' started.");
findPos =(char *)strstr(sSrc, sMatchStr);
if( (!findPos) || (!sMatchStr) ){
lr_debug_message(LR_MSG_CLASS_EXTENDED_LOG ,"Notify:Function 'ReplaceStr' ended with error!");
return -1;
}
while( findPos)
{
memset(caNewString, 0, sizeof(caNewString));
StringLen = findPos - sSrc;
strncpy(caNewString, sSrc, StringLen);
strcat(caNewString, sReplaceStr);
strcat(caNewString, findPos + strlen(sMatchStr));
strcpy(sSrc, caNewString);
findPos =(char *)strstr(sSrc, sMatchStr);
}
lr_debug_message(LR_MSG_CLASS_EXTENDED_LOG,"Result:%s",sSrc);
free(findPos);
lr_debug_message(LR_MSG_CLASS_EXTENDED_LOG ,"Notify:Function 'ReplaceStr' ended (Duration: %lf)",
lr_end_timer(timer_ReplaceStr));
return 0;
}
2.在init/Action/end 中调用:
char strView[1024];
web_reg_save_param("viewState5",
"LB=\"javax.faces.ViewState\" value=\"",
"RB=\"",
LAST);
sprintf(strView,lr_eval_string("{viewState5}"));
ReplaceStr(strView,"+","+");
ReplaceStr(strView,"/","/");
ReplaceStr(strView,"=","-");
lr_save_string(lr_eval_string(strView), "viewState6");
memset(strView,0,sizeof(strView));
