[讨论] LoadRunner中多值关联的3种处理方式

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
web_submit_data("FreeQueryServlet_24",
  "Action=http://datasvr01:8081/freequery/FreeQueryServlet",
  "Method=POST",
  "RecContentType=text/html",
  "Referer=http://datasvr01:8081/freequery/js/freequery/businessview/Preview.html",
  "Snapshot=t27.inf",
  "Mode=HTTP",
  ITEMDATA,
  "Name=className", "Value=ClientReportService", ENDITEM,
  "Name=methodName", "Value=addNewParam", ENDITEM,
  "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,"",""]");
web_submit_data("FreeQueryServlet_24",
  "Action=http://datasvr01:8081/freequery/FreeQueryServlet",
  "Method=POST",
  "RecContentType=text/html",
  "Referer=http://datasvr01:8081/freequery/js/freequery/businessview/Preview.html",
  "Snapshot=t27.inf",
  "Mode=HTTP",
  ITEMDATA,
  "Name=className", "Value=ClientReportService", ENDITEM,
  "Name=methodName", "Value=addNewParam", ENDITEM,
  "Name=params", s, 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);
web_submit_data("FreeQueryServlet_24",
  "Action=http://datasvr01:8081/freequery/FreeQueryServlet",
  "Method=POST",
  "RecContentType=text/html",
  "Referer=http://datasvr01:8081/freequery/js/freequery/businessview/Preview.html",
  "Snapshot=t27.inf",
  "Mode=HTTP",
  ITEMDATA,
  "Name=className", "Value=ClientReportService", ENDITEM,
  "Name=methodName", "Value=addNewParam", ENDITEM,
  "Name=params", s, ENDITEM,
  LAST);

i++;
