loadrunner获取登陆响应头信息，并截取想要的信息作为参数

我直接贴代码吧。感觉这些东西都比较简单，就是C的语法不懂，不过都是网上找的。

void web_reg_save_param_custom(char *sourceStr, char* outpuStr, char *leftBdry, char *rightBdry){     
 
    char *st1, *st2;
 
    int result, i = 0;
 
    i=strlen(leftBdry);
 
    st1 = (char*) strstr(sourceStr, leftBdry); 
 
    if (st1 != NULL){ 
 
        st1 += i;
 
        st2 = (char*) strstr(st1, rightBdry);
 
        if (st2 != NULL){
 
            result = st2 - st1;
 
            *(st1 + result) = '\0';
 
            }     
        }  
 
    if ((st1 == NULL) || (st2 == NULL))
 
        lr_error_message("Error: No substring found for the specified boundary");
 
    else  
 
        lr_save_string(lr_eval_string(st1), outpuStr); 
}
 
test()
{
 
	lr_think_time(1);
	web_set_max_html_param_len("262144"); // 默认最大长度为256
	web_reg_save_param("ResponseBody", "LB=", "RB=", "Search=Body", LAST);
	web_save_header(REQUEST, "RequestHeader");// REQUEST为内置变量，保存请求的头信息，需在发送URL请求前注册使用，将请求头信息存入字符串RequestHeader中
	web_save_header(RESPONSE, "ResponseHeader");// 将RESPONSE保存响应的头信息在字符串ResponseHeader中
