首先我将其转换为 JSON:
capture_json <- rjson::toJSON(capture)
然后我将它缩小到只包含 .customFields，然后我根据我想要的 customFieldId 过滤它：
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 工具并按 .[]|.assignedValue 过滤时，它 return 是我想要的值：
"Male"
"Caucasian"
"31"
You can see for yourself in this link.
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 该脚本时，它所做的只是 return 空值，如下所示：
[
null,
null,
null
]
我做错了什么？为什么它在我上面提供的 jqplay link 中工作正常，但没有在 R 中使用 jqr 包？
我们可以将语法更改为，因为结构与网站上的一个 OP 运行 略有不同
> capture_jq %>% jq('."assignedValue"')
[
"Male",
"Caucasian",
"31"
]

首先我将其转换为 JSON:
capture_json <- rjson::toJSON(capture)
然后我将它缩小到只包含 .customFields，然后我根据我想要的 customFieldId 过滤它：
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 工具并按 .[]|.assignedValue 过滤时，它 return 是我想要的值：
"Male"
"Caucasian"
"31"
You can see for yourself in this link.
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 该脚本时，它所做的只是 return 空值，如下所示：
[
null,
null,
null
]
我做错了什么？为什么它在我上面提供的 jqplay link 中工作正常，但没有在 R 中使用 jqr 包？
我们可以将语法更改为，因为结构与网站上的一个 OP 运行 略有不同
> capture_jq %>% jq('."assignedValue"')
[
"Male",
"Caucasian",
"31"
]
