正确使用匹配器用于jmeter变量

Question

我需要在表格中计算行数。所以我用reg。进出口。提取。但响应断言以错误结束，并试图找到rows:${ROWS_matchnr}。

我试过谷歌，但我只找到一些非功能性建议。

        Response Assertion(rows:${ROWS_matchnr})

Answer 1

将Match No字段中的值从0更改为-1。正如ahem所述，useless official help：

If the match number is set to a negative number, then all the possible matches in the sampler data are processed. The variables are set as follows:

   refName_matchNr - the number of matches found; could be 0
   refName_n, where n = 1,2,3 etc - the strings as generated by the template
   refName_n_gm, where m=0,1,2 - the groups for match n
   refName - always set to the default value
   refName_gn - not set

然后将$ {ROWS_matchnr}更改为$ {ROWS_matchNr}（大写N），它应该有效。

如果您仍有问题，请使用Debug Sampler查看正则表达式返回的内容。
