用于REST-fetching路径的值列表

Question

我正在使用REST-Assured测试一些restfulweb服务。以下是我的JSON：

{
    "status":true,
    "responseData":{
        "orderLevelReasons":[
            {
                "reasons":[

                        "reasonId":"ef2b4147-ee76-4961-b784-63e848a84167",

                        "reasonId":"c432f563-f835-4710-8055-5ee9e0fe1409",
                        "reasonName":"Some reason7"

                "orderItemName":"Item1",
                "orderItemId":961253,
                "hint":""
            }
        ]
    },
    "message":"OK"
}

我想取：

1. responseData下所有reasonId值的列表。订单级别原因
2. responseData下所有reasonId值的列表。productLevelReasons其中，orderItemId为961253（因为多个orderItemId可能存在productLevelReasons）

我在谷歌上搜索了很多，发现这可以通过使用JsonPath来实现，但我无法弄清楚对于我的每一个目的，JsonPath表达式到底是什么。

Answer 1

响应ata.orderLevelReasons下的所有原因值列表

$.responseData.orderLevelReasons[*].reasons[*].reasonId

如果要从orderLevelReasons集合中的所有项中查找原因，则必须使用[*]for orderLevelReasons。如果不是，您可以将其替换为[0]，并可以得到一个不同的列表（假设每个OrderLevelReasions重复相同的原因）。

responseData下所有reasonId值的列表。productLevelReasons，其中orderItemId为961253（因为多个orderItemId可能有productLevelReasons）。

$.responseData.productLevelReasons[?(@.orderItemId=='961253')].reasons[*].reasonId

这也是不明确的。如果可能存在重复的原因，您需要删除重复。

我在jsonpath.curiousconcept.com验证了两个JsonPath表达式，它们都是有效的。但是Java代码由于某种原因会出错。

我已经调查过了。放心框架实际上并没有实现JsonPath，而是为JSON实现了一种专有的基于路径的查询语法。不幸的是，这个名字是一样的，但实际上是基于一个完全不同的标准。

本文档页面说明：

请注意，JsonPath实现使用Groovy的GPath语法，不要与Jayway的JsonPath实现混淆。

StackOverflow上的JsonPath标记与已接受的JsonPath规范有关，而不是与rest规范有关。

根据我的研究，我会得出结论，放心的jsonpath实现不支持您的需求。您应该使用这样的实现，例如Jayway的实现。
