JMeter学习-011-JMeter 后置处理器实例之 - 正则表达式提取器（三）多参数获取进阶引用篇

前两篇文章分表讲述了后置处理器 - 正则表达式提取器概述及简单实例、多参数获取，相应博文敬请参阅简单实例、多参数获取。

此文主要讲述如何引用正则表达式提取器获取的数据信息。其实，正则表达式提取器获取的数据，均可看做一个变量（单个数据，此处指所需获取的测试相关数据）或数组（多个数据），通过引用变量或者数组的数据，达到应用其数据的目的。下面针对此两种方式进行介绍。

第一种：单数据变量

但数据变量的应用比较简单，同我们日常 shell 脚本引用变量相同，引用样式：${引用名称}。例如要引用下图中的变量，引用方式为：${price}。

第二种：多数据变量（数组）

多数据变量（数组）的提取器配置如下图所示：

通过调试工具 DPP，我们可以获取上述 goodInfo 的相关信息如下所示：

goodInfo=2142670,101-006-72936,628800
goodInfo_g=5
goodInfo_g0=sysNo":"2142670","skuid":"487623639432","productID":"101-006-72936","productTitle":"苹果（Apple）iPhone 6 Plus (A1593) 64GB 银色 移动4G手机","price":"628800","
goodInfo_g1=2142670
goodInfo_g2=","skuid":"487623639432","
goodInfo_g3=101-006-72936
goodInfo_g4=productTitle":"苹果（Apple）iPhone 6 Plus (A1593) 64GB 银色 移动4G手机
goodInfo_g5=628800

通过上述信息，结合正则表达式提取器的配置信息，我们可以很容易的看出，配置中模板 $1$ 中的数字，对应上述信息中的不同数据。例如：若模板为 $0$，则最终的数据为上述第三行等号后的数据；若模板为 $3$，则最终数据为 101-006-72936。上述提取器的模板为： $1$,$3$,$5$，最终的数据为 2142670,101-006-72936,628800。那么若是想要获取 101-006-72936，改怎么引用呢？相信聪明的你已经在上述信息中发现了，对了，实际应用的表达式为： ${goodInfo_g3}。

下面就以获取商品编号，并通过商品编号搜索商品，同时通过商品系统编号、商品价格验证搜索结果是否正确（商品搜索的 HTTP请求获取请小主自行获取，谢谢！），依据下图所示，将搜索请求中的关键字参数化为上步 HTTP请求中的商品编号。

最终脚本执行结果如下所示（断言请小主自行仿照配置）：
