首先将其转换为JSON:
capture_json <- rjson::toJSON(capture)
然后我把它缩小到只包括.customFields，然后我过滤了我想要的customFieldId:
capture_jq <- capture_json %>% jqr::jq('.customFields') %>% jq('.[] | select(.customField.customFieldId | IN(83,84,85))')
使用JSON数据，我试图提取assignedValue字段中列出的值。当我使用jq工具和.[]|.assignedValue过滤器时，它返回我想要的值:
"Male"
"Caucasian"
"31"
你可以在这个链接中看到。
在我的R脚本中，JSON数据存储在一个名为capture_jq的变量中，然后我运行这个脚本:
assigned_values <- capture_jq %>% jq('.[]|."assignedValue"')
但是当我运行这个脚本时，它所做的就是返回空值，看起来像这样:
[
null,
null,
null
]
我做错了什么?为什么它在我上面提供的jqplay链接中工作良好，但在R中不使用jqr包?
我们可以更改语法，因为结构与在网站上运行的OP略有不同
> capture_jq %>% jq('."assignedValue"')
[
"Male",
"Caucasian",
"31"
]
