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

  "Name=params", "Value=["{ClientID}","OutputParameter.{Value}",""]", ENDITEM,
  LAST);

//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,"",""]");

  ITEMDATA,
  "Name=className", "Value=ClientReportService", ENDITEM,
  "Name=methodName", "Value=addNewParam", ENDITEM,

  LAST);

//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
sprintf(s,"Value=["{ClientID}","OutputParameter.%s",""]",str);
