需求：通过关联取得的ParamName参数可能存在多个值，需要对每个ParamName参数值进行处理

脚本：可通过3种不同的实现方式，将每个参数值作为HTTP请求内容发出

web_reg_save_param("ParamName",

"LB/IC="id":"OutputParameter.",

"RB/IC=","",

"Ord=All",

"Search=Body",

"RelFrameId=1",

LAST);

...

Paramcount=atoi(lr_eval_string("{ParamName_count}")); //参数个数

i=1;

while (i<=Paramcount) {

sprintf(str,"{ParamName_%d}",i);        //生成ParamName_i

//方法一:将变量转为参数，直接在请求中使用参数

lr_save_string(lr_eval_string(str),"Value"); //对每个参数进行处理

//方法二：通过strcpy、strcat方式组织字符串，通过变量发送请求

strcpy(s,"Value=["{ClientID}","OutputParameter.");

strcat(s,str);

strcat(s,"",""]");
