loadrunner12.55：delete请求删除数据，响应删除成功，但是实际未删除，响应结果与实际结果不符

问题描述：

脚本实现删除场景名称为test1的记录，删除请求响应删除成功{"success":true,"data":"","code":200,"message":"删除成功！"}，但是前台显示该数据仍然存在

原脚本实现如下：

Action()
{
	int i=1,busiSceneIdnum;
	char* busiSceneId;

	web_add_auto_header("Accept-Language", 
		"zh-Hans-CN,zh-Hans;q=0.5");
	
	web_reg_save_param("queryResponseBody",
		"LB=",
		"RB=",
		"Search=Body",
		LAST);
	
	web_custom_request("queryScene", 
		"URL=http://10.248.57.226:9010/user-center/uap-app-scene/queryScene", 
		"Method=POST", 
		"Resource=0", 
		"RecContentType=application/json", 
		"Referer=http://10.248.57.226:9010/U-C/", 
		"Snapshot=t23.inf", 
		"Mode=HTML", 
		"EncType=application/json;charset=utf-8", 
		"Body={"current":1,"size":10,"busiSceneId":"","sceneName":""}", 
		LAST);
	
		// Create a Json object from a string.
    lr_eval_json("Buffer={queryResponseBody}",
                 "JsonObject=json_obj_1", LAST);
	    
	busiSceneIdnum=lr_json_get_values("JsonObject=json_obj_1",//获取响应体所有busiSceneId字段值并保存到数组JinKuList中，用于后面删除的参数化
                "ValueParam=JinKuList",
                "QueryString=$.data.tablesArr[*].busiSceneId",
                "SelectAll=Yes",
                 LAST);

	
	while(i<busiSceneIdnum){
		lr_save_int(i,"index");
		busiSceneId=lr_eval_string("{JinKuList_{index}}");
		lr_output_message("busiSceneId=%s",lr_eval_string(busiSceneId));

		//{"success":true,"data":"","code":200,"message":"删除成功！"}
		web_reg_save_param("ResponseBody",
			"LB=",
			"RB=",
			"Search=Body",
			LAST);
	
		web_reg_save_param("respStatus",
			"LB="success":",
			"RB=,"data",
			"Search=Body",
			LAST);	
	
		web_reg_save_param("respMsg",
			"LB=message":"",
			"RB="}",
			"Search=Body",
			LAST);		

		lr_start_transaction("deleteJinKu");
		web_custom_request("delete", 
		    "URL=http://10.248.57.226:9010/user-center/uap-app-scene/delete?busiSceneId=lr_eval_string(busiSceneId)&state=-1",
			"Method=DELETE", 
			"Resource=0", 
			"RecContentType=application/json", 
			"Referer=http://10.248.57.226:9010/U-C/", 
			"Snapshot=t24.inf", 
			"Mode=HTML", 
			LAST);
		
		if(lr_eval_string("{respStatus}")){
			lr_output_message("删除金库成功");
			lr_end_transaction("deleteJinKu", LR_PASS);
	
		}else{
			lr_error_message("删除金库失败，失败原因为：%s",lr_eval_string("{respMsg}"));
			lr_end_transaction("deleteJinKu", LR_FAIL);
	
		}	
	
		
		i=i+1;
	}
	
	
	web_reg_save_param("LastResponseBody",
		"LB=",
		"RB=",
		"Search=Body",
		LAST);

	web_custom_request("queryScene_2", 
		"URL=http://10.248.57.226:9010/user-center/uap-app-scene/queryScene", 
		"Method=POST", 
		"Resource=0", 
		"RecContentType=application/json", 
		"Referer=http://10.248.57.226:9010/U-C/", 
		"Snapshot=t25.inf", 
		"Mode=HTML", 
		"EncType=application/json;charset=utf-8", 
		"Body={"size":5,"current":1,"busiSceneId":"","sceneName":""}", 
		LAST);

	return 0;
}

　　日志显示：

经与开发沟通定位显示：实际发送的删除请求地址为http://10.248.57.226:9010/user-center/uap-app-scene/delete?busiSceneId=lr_eval_string(busiSceneId)&state=-1，说明lr_eval_string(busiSceneId)函数的参数化并未起作用，而是本身作为字符串发起了请求，而系统针对非失败的请求均响应成功，所以问题解决的根本在于请求中的busiSceneId字段如何取值。

解决办法：

将请求地址url进行参数拼接实现，实现脚本如下：

lr_save_string(lr_paramarr_idx("JinKuList", i), "busiSceneId");//获取数组JinKuList中索引为i的值

　　

		web_custom_request("delete", 
		    "URL=http://10.248.57.226:9010/user-center/uap-app-scene/delete?busiSceneId={busiSceneId}&state=-1",
			"Method=DELETE", 
			"Resource=0", 
			"RecContentType=application/json", 
			"Referer=http://10.248.57.226:9010/U-C/", 
			"Snapshot=t24.inf", 
			"Mode=HTML", 
			LAST);

优化后的完整脚本如下：

Action()
{
	int i=1,busiSceneIdnum;

	web_add_auto_header("Accept-Language", 
		"zh-Hans-CN,zh-Hans;q=0.5");
