JMeter如何使用正则表达式提取器从响应的条目数组中提取id

Question

我对JMeter完全陌生。我也有类似的JMeter问题:从数组响应中提取正则表达式，这里我使用了相同的测试负载。我正在尝试使用正则表达式提取器，并希望提取所有addressIds。即[0011442239，0011442246]。我有一个post请求要发送，有效载荷只有addressIds数组。有人能帮我一下吗？

我试图使用\[（[^\]]）\]，但这没有奏效。如上所述，我对JMeter和Regular Expressin完全陌生。

抱歉，我的错误是，我希望响应为整数数组。即[0011442239、0011442246]。

谢谢

您的响应是JSON，因此您应该考虑使用允许执行任意JMESPath查询的JSON JMESPath Extractor，而不是尝试使用正则表达式解析它。

特别是在您的情况下，您可以使用以下表达式得出这些地址ID的逗号分隔列表：

[*].addressId | join(',',@)

演示:

如果您确实需要用引号将这些addressId括起来，则需要切换到JSR223 PostProcessor和以下Groovy代码：

com.jayway.jsonpath.JsonPath.read(prev.getResponseDataAsString(),'$..addressId').collect {it -> "\"$it\""} as String
