[英]How to extract nested elements in JSON response using JSON extractor in JMeter
我想根据嵌套 JSON 响应中的条件提取一个元素。 使用下面广泛搜索的示例,我想提取“Foo Bar”创作的所有书籍的 storeid:
{
"store": {
"storeId": 1
"book": [
{
"category": "reference",
"author": [
{
"Nigel Rees",
"Foo Bar"
}
],
"title": "Sayings of the Century",
"price": 8.95
},
{
"category": "fiction",
"author": [
{
"Evelyn Waugh"
}
],
"title": "Sword of Honour",
"price": 12.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}
我尝试使用如下表达式: $.store[?(@..author=='Foo Bar')].storeId
我还尝试使用以下方法查看是否有任何商店返回: $.store[*].book[?(@.author=='Foo Bar')]
但没有返回结果......请帮助。 谢谢!
您生成的不是有效的 JSON ,因此您将无法在其上使用 JSON Extractor。
如果你修改这个你甚至不能正确复制和粘贴以包含你的storeId
的好例子:
{
"store": {
"storeId": 1,
"book": [
{
"category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},
{
"category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},
{
"category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"isbn": "0-395-19395-8",
"price": 22.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}
您将能够使用以下表达式提取其中一位作者是Nigel Rees
的storeId
:
$.store[?(@.book[?(@.author=="Nigel Rees")])].storeId
