jsonpath使用
1、jsonpath介绍：
首先，JsonPath 是一种信息抽取类库，是从JSON文档中抽取指定信息的工具，提供多种语言实现版本，包括：Javascript, Python， PHP 和 Java。直白点的话就是独立的可以配合多种语言进行匹配的目标值的一种类库，和jmeter中的jsonPath匹配方式很像
2、语法说明：
JSONPath 表达式总是以与 XPath 表达式与 XML 文档结合使用的相同方式引用 JSON 结构。由于 JSON 结构通常是匿名的并且不一定具有“根成员对象”，因此 JSONPath 假定$分配给外层对象的抽象名称。
JSONPath 表达式可以使用点符号
$.store.book[0].title
或括号 -符号
$['store']['book'][0]['title']
对于输入路径。内部或输出路径将始终转换为更通用的括号 -符号。
JSONPath 允许将通配符* 用于成员名称和数组索引。它借用后代从操作者“..” E4X和阵列切片语法提案[start:end:step]从EcmaScript的4。
底层脚本语言的表达式(
$.store.book[(@.length-1)].title
对当前对象使用符号“@”。过滤器表达式通过语法的支持?(
$.store.book[?(@.price < 10)].title
这是 JSONPath 语法元素与其对应的 XPath 的完整概述和并排比较
3、举例说明，结合实列对比说明：
data = { "store": {
"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
}
}
}匹配结果：
4、以实际订单数据举例：
