## Action执行多次 ##

Vuser → Run-Time Settings → Run logic → Nmber of iterations 输入次数 → 保存

## 参数化 ##

**[更多参数化示例][Link 1]**

脚本示例：

web_submit_data("login.pl", 
    		"Action=http://127.0.0.1:1080/WebTours/login.pl", 
    		"Method=POST", 
    		"TargetFrame=info", 
    		"RecContentType=text/html", 
    		"Referer=http://127.0.0.1:1080/WebTours/login.pl?username=&password=&getInfo=true", 
    		"Snapshot=t4.inf", 
    		"Mode=HTML", 
    		ITEMDATA, 
    		"Name=username", "Value=zhangsan", ENDITEM,  //参数化这个zhang
    		"Name=password", "Value=123456", ENDITEM, 
    		"Name=passwordConfirm", "Value=123456", ENDITEM, 
    		"Name=firstName", "Value=bing", ENDITEM, 
    		"Name=lastName", "Value=wei", ENDITEM, 
    		"Name=address1", "Value=shanghaipudong", ENDITEM, 
    		"Name=address2", "Value=shanghai", ENDITEM, 
    		"Name=register.x", "Value=57", ENDITEM, 
    		"Name=register.y", "Value=4", ENDITEM, 
    		LAST);

测试时经常需要大批量使用数据，下面简单示例参数化方法。

### 使用IterationNmber ###

1、选中需要参数化的值 → 鼠标右键 → Replace with a parameter  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 1][]

2、自己可以在`parameter`键入一个名称 → Parameter type 选择Iteration Nmber → 选择Properties  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 2][]

3、选择数据类型  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 3][]

4、完成  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 4][]

变更后demo：

web_submit_data("login.pl",
    		"Action=http://127.0.0.1:1080/WebTours/login.pl",
    		"Method=POST",
    		"TargetFrame=info",
    		"RecContentType=text/html",
    		"Referer=http://127.0.0.1:1080/WebTours/login.pl?username=&password=&getInfo=true",
    		"Snapshot=t4.inf",
    		"Mode=HTML",
    		ITEMDATA,
    		"Name=username", "Value=a{NewParam_1}", ENDITEM, //在这
    		"Name=password", "Value=123456", ENDITEM,
    		"Name=passwordConfirm", "Value=123456", ENDITEM,
    		"Name=firstName", "Value=bing", ENDITEM,
    		"Name=lastName", "Value=wei", ENDITEM,
    		"Name=address1", "Value=shanghaipudong", ENDITEM,
    		"Name=address2", "Value=shanghai", ENDITEM,
    		"Name=register.x", "Value=57", ENDITEM,
    		"Name=register.y", "Value=4", ENDITEM,
    		LAST);

执行结果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 5][]

### 使用文件进行参数化 ###

2、自己可以在`parameter`键入一个名称 → 选择Properties  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 6][]

3、来一个名字 → 点击下面的Create Table  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 7][]

4、添加数据 → Add Row 增加行  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 8][]

**也可以自己创建`.dat`文件，点击`Browse`选择自己创建的文件**

5、保存  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 9][]

6、到这里数据就添加好了，当这个脚本使用多次时就会第一次使用aaa，第二次bbb了…以此类推  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 10][]

参数化后的脚本demo：

web_submit_data("login.pl", 
    		"Action=http://127.0.0.1:1080/WebTours/login.pl", 
    		"Method=POST", 
    		"TargetFrame=info", 
    		"RecContentType=text/html", 
    		"Referer=http://127.0.0.1:1080/WebTours/login.pl?username=&password=&getInfo=true", 
    		"Snapshot=t4.inf", 
    		"Mode=HTML", 
    		ITEMDATA, 
    		"Name=username", "Value=zhang{NewParam_2}", ENDITEM, 
    		"Name=password", "Value=123456", ENDITEM, 
    		"Name=passwordConfirm", "Value=123456", ENDITEM, 
    		"Name=firstName", "Value=bing", ENDITEM, 
    		"Name=lastName", "Value=wei", ENDITEM, 
    		"Name=address1", "Value=shanghaipudong", ENDITEM, 
    		"Name=address2", "Value=shanghai", ENDITEM, 
    		"Name=register.x", "Value=57", ENDITEM, 
    		"Name=register.y", "Value=4", ENDITEM, 
    		LAST);

如果忘记了以前的脚本参数化了什么东西，可鼠标右键我们的参数化变量 → Parameter properties…

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 11][]

这样就可以看到我们的参数化数据了(前提那个dat文件还在)  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 12][]

### 使用Random (随机)参数化 ###

2、自己可以在`parameter`键入一个名称 → Parameter type 选择Random Number → 选择Properties  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 13][]

3、设置最大数、最小数，选择格式 → 点close  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 14][]  
首先看数据类型是随机数类型的，生成随机数的范围是多少，比如是1-100，关键看NUM的数字类型了，%08lu这个标识的是位数，你选择之后发现SMPLE列也跟着改变了。

Each iteration：每一次迭代
    
    Each occurrence：每次更新
    
    Once:一直只用那一个参数（他不管你循环几次）

4、点OK就完成了  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 15][]

为了防止产生重复的数据我们可以设置两个random，防止产生重复的数据

web_submit_data("login.pl", 
    		"Action=http://127.0.0.1:1080/WebTours/login.pl", 
    		"Method=POST", 
    		"TargetFrame=info", 
    		"RecContentType=text/html", 
    		"Referer=http://127.0.0.1:1080/WebTours/login.pl?username=&password=&getInfo=true", 
    		"Snapshot=t4.inf", 
    		"Mode=HTML", 
    		ITEMDATA, 
    		"Name=username", "Value=b{NewParam_3}{NewParam_4}", ENDITEM, //为了防止重复我们可以设置两个跨度较大的random这样产生重复的几率就小了
    		"Name=password", "Value=123456", ENDITEM, 
    		"Name=passwordConfirm", "Value=123456", ENDITEM, 
    		"Name=firstName", "Value=bing", ENDITEM, 
    		"Name=lastName", "Value=wei", ENDITEM, 
    		"Name=address1", "Value=shanghaipudong", ENDITEM, 
    		"Name=address2", "Value=shanghai", ENDITEM, 
    		"Name=register.x", "Value=57", ENDITEM, 
    		"Name=register.y", "Value=4", ENDITEM, 
    		LAST);

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 16][]

### 删除不需要的参数 ###

脚本中创建的参入如random参数，使用键盘直接删除未删除彻底，打断点运行时还能看到该参数，所以我们需要手动进行删除，步骤如下：

1、随意选择一个值鼠标右键 → Use Existing Parameter → Select from Parameter List  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 17][]

2、 选择不要的参数删除（如果不删除磁盘上的文件可忽略第三的的打钩）  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 18][]

### 参数化时随机使用文件中的内容 ###

2、自己可以在`parameter`键入一个名称 → 选择Properties  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 6][]

3、选择参数化文件![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 19][]

4、设置下一行参数使用的方式为随机  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 20][]

sequential：依顺序使用
    random：随机
    unique：一直使用一个

6、保存  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYTY0NzYwMDM_size_16_color_FFFFFF_t_70 21][]

文件内容：

用户名
    usergj01
    usergj02
    usergj03

完整脚本：

Action()
    {
        lr_save_string(lr_eval_string("{NewParam_1}"),"date");
    
        lr_message("使用的是:%s",lr_eval_string("{date}"));
    
    
        return 0;
    }

执行结果：

使用的是:usergj03
    
    使用的是:usergj01
    
    使用的是:usergj03
    
    使用的是:usergj02
