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,"\",\"\"]");

 //方法三：通过sprintf格式化输出生成需要的字符串，通过变量发送请求
