推荐答案

您可以按照以下顺序，

(如果你知道有多少产品那么)

(If you know how many products are there then)

1. add random variable with values 1-no. of products. this will generate random values for each user/iteration
2. use values from random variable (var1) in regular expression extractor for random occurance (var1 occurance which is random every time)

(如果你不知道有多少产品存在，如果你的回复包含产品数量)

(If you dont know how many products are present and if your response contains no. of products count then)

1. In first regular expression extract count of products in a variable 
2. add random variable with values 1-value for first regex. this will generate random values for each user/iteration
3. use values from random variable (var1) in regular expression extractor for random occurance

我在我的 assgn 中使用了类似的技术.附上快照以供参考.

I have used similar technique in my assgn. attaching snapshots for reference.

随机选择器

计数的第一个正则表达式

first regex for count

随机变量

随机出现的第二个正则表达式

2nd regex for random oocurance

您可以根据需要修改正则表达式.

you can modify regex as per your requirement.
