需要在loadrunner里面获得“15”（下面红色高亮的部分），并做成关联参数。
//Body response 内容： <BODY><; PRE>//OK[8,7,5,15,6,5,0,4,0,3,0,3,2,0,0,0,1
用web_reg_save_param取出“8,7,5,15,6,5,0,4,0,3,0,3,2,0,0,0,1”这一段，然后用strtok函数切割出一个个数字，第四个数字就是要找的值
例如:
extern char * strtok(char * string, const char * delimiters ); // Explicit declaration
char separators[] = ",";
char * token;
lr_save_string("1,2,3,4,5,6","str");
token = (char *)strtok(lr_eval_string("{str}"), separators); // Get the first token
if (!token) {
lr_output_message ("No tokens found in string!");
return( -1 );
}
while (token != NULL ) { // While valid tokens are returned
lr_output_message ("%s", token );
token = (char *)strtok(NULL, separators); // Get the next token
}
