Question

我使用REST-Assured来测试一些RESTful Web服务。这是我的JSON：

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

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

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

我想抓取：

下面所有reasonId值的列表 responseData.orderLevelReasons。
所有reasonId值的列表在responseData.productLevelReasons下orderItemId 961253（因为可能有多个orderItemIds的productLevelReasons）。

我用Google搜索了很多内容并发现这可以使用JsonPath来实现，但我无法弄清楚JsonPath表达式究竟是出于什么目的。

Answer 1

responseData.orderLevelReasons
下所有reasonId值的列表

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

如果您想要orderLevelReasons集合中所有项目的原因，则必须使用orderLevelReasons [*]。如果不是，您可以用[0]替换它，并且您可以获得一个不同的列表（假设每个orderLevelReasons都重复相同的原因）。

responseData.productLevelReasons下所有reasonId值的列表其中orderItemId是961253（因为可能有productLevelReasons multiple orderItemIds）。

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

这也不明显。如果存在重复原因，您需要删除重复。

我验证了你的两个JsonPath表达式 jsonpath.curiousconcept.com，两者都有效。但是Java代码出于某种原因出错。

我已经研究过了。保证的框架实际上并不实现JSONPath，而是基于JSON的专有路径查询语法。不幸的是，名称是相同的，但它实际上是基于完全不同的标准。

这docs page解释了：

请注意，JsonPath实现使用Groovy的GPath语法和不要与Jayway的JsonPath实现相混淆。

StackOverflow上的JsonPath标记与accepted JsonPath规范有关，而不是有保证的规范。

根据我的研究，我会得出结论，确定的jsonpath实现不支持您的要求。您应该使用具有的实现，例如Jayway's one。
