在VuGen中默认使用{}的字符串称为参数
注意：参数必须在双引号中才能用
将字符串保存为参数
lr_save_string("string you want to save", "arg_name");
举例：用参数来替换需要打开的url链接
Action2()
{
lr_save_string("http://172.25.75.2:1080/WebTours/", "web_site");
//打开登录页面
web_url("WebTours",
"URL = {web_site}", //运行出错//改成"URL= {web_site}"即可
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
return 0;
}
运行报错：
Action2.c(6): Error -27226: The "URL = http://172.25.75.2:1080/WebTours/" argument (number 2) is unrecognized or misplaced [MsgId: MERR-27226]
Action2.c(6): web_url("WebTours") highest severity level was "ERROR", 0 body bytes, 0 header bytes [MsgId: MMSG-26388]
解决方法：
"URL = {web_site}",URL和等号”=”之间多出了一个空格，去掉该空格即可。
所以使用lr_eval_string()函数的时候也是使用双引号来调用的。
还可以如下方式
Action2()
{
lr_save_string("http://172.25.75.2:1080/", "web_site");
lr_save_string("WebTours/", "web_name");
//打开登录页面
web_url("WebTours",
"URL={web_site}{web_name}",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
return 0;
}
获取参数值的字符串表识
可用lr_eval_string函数获取参数值的字符串标表示，然后用lr_output_message()函数输出结果
Action2()
{
lr_save_string("http://172.25.75.2:1080/", "web_site");
lr_save_string("WebTours/", "web_name");
lr_output_message(lr_eval_string("获取参数值的字符串表示：{web_site}{web_name}"));
//打开登录页面
web_url("WebTours",
"URL= {web_site}{web_name}",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
return 0;
}
注：如果想获取参数字符串的第一个字母，同c,可以这样：lr_eval_string(“{param}”)[0];
将int型数字保存为参数
lr_save_int(int_number, “param_name”)
例如：
Action2()
{
lr_save_int(0, "int_param");
//打开登录页面
web_url("WebTours",
"URL=http://172.25.75.2:1080/WebTours/",
// "Resource=0",
"Resource={int_parma}",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
return 0;
}
把时间保存为参数
通过lr_save_datetime函数来实现。
函数原型：
void lr_save_datetime(const char *format, int offset, const char *name);
format：期望输出的日期格式，如：%Y、%m、%d、%X等
offset：类似与表示时间的一些关键字常量：
DATE_NOW -> 现在的日期
TIME_NOW -> 现在的时间
ONE_DAY -> 一天的时间
ONE_HOUR -> 一小时的时间
ONE_MIN -> 一分钟的时间
需要注意的是，他们可以单独使用，也可以联合使用
DATE_NOW + TIME_NOW -> 当前时间
DATE_NOW-ONE_DAY -> 昨天
DATE_NOW+ONE_DAY -> 明天
两天前的日期
DATE_NOW-2*(ONE_DAY)、 DATE_NOW-2*24*(ONE_HOUR)、 DATE_NOW-2*24*60*(ONE_MIN)
2个小时后的时间
TIME_NOW+2*(ONE_HOUR)
TIME_NOW+2*60*(ONE_MIN)
name：期望将时间保存到的那个参数的名称
format格式参照表：

Action()
{

把内容保存为带格式的参数
lr_param_sprintf(param_name,format,var1,var2,…);
示例：
Action2()
{
int index = 56;
char *suffix = "txt";
lr_param_sprintf("NewParam","log_%d.%s",index,suffix);
lr_output_message("The new file name is %s",lr_eval_string("{NewParam}"));
return 0;}
运行结果：
