大家好，

我是学压力测试初学者， 我的代码出现下面的错误， 请帮我看看什么问题， 谢谢

代码:
string1 ="URL=http://192.168.0.5:6005/eos-default/common/skins/outlook/com.fhd.questionanswer.queTargetAnswerIframe.flow?operatorrisksid=";
string2 = "&questsetid=";
string3 = "&targetid=";
string4 = "&current=0&isFirst=true&isLast=true&targetTypeName=%E9%A3%8E%E9%99%A9&viewType=1&isCurrentLast=false";          

operatorrisksidv = lr_eval_string("{operatorrisksid}");
questsetidv = lr_eval_string("{questsetid}");
targetidv = lr_eval_string("{targetid}");

lr_output_message ("operatorrisksidv is %s", operatorrisksidv);
lr_output_message ("questsetidv is %s", questsetidv);
lr_output_message ("targetidv is %s", targetidv);

strcat(string1, operatorrisksidv);
strcat(string1, string2);
strcat(string1, questsetidv);
strcat(string1, string3);
strcat(string1, targetidv);
strcat(string1, string4);

lr_output_message ("Full path of file is %s", string1);

错误：
Action.c(362): Error: C interpreter run time error: Action.c (362):  Error -- memory violation : Exception ACCESS_VIOLATION received.

解决：


         operatorrisksidv = lr_eval_string("{operatorrisksid}");
         questsetidv = lr_eval_string("{questsetid}");
         targetidv = lr_eval_string("{targetid}");

       

         lr_output_message ("string1 is %s", string1);
         lr_output_message ("string2 is %s", string2);
         lr_output_message ("string3 is %s", string4);
         lr_output_message ("string4 is %s", string4);

         
         URLAddress = (char *)malloc(strlen(string1)+strlen(operatorrisksidv)+strlen(string2)+strlen(questsetidv)+strlen(string3)+strlen(targetidv)+strlen(string4)+1) ;

    strcat(URLAddress, string1);
        strcat(URLAddress, operatorrisksidv);
         lr_output_message ("Full path of file is %s", string1);
        strcat(URLAddress, string2);
        strcat(URLAddress, questsetidv);
        strcat(URLAddress, string3);
        strcat(URLAddress, targetidv);
        strcat(URLAddress, string4);


    lr_output_message ("Full path of file is %s", URLAddress);
