导出到 CSV 时如何不让 jq 解释换行符

Question

我要转换存储在文件中的以下JSON内容tmp.json

{
    "results": [
        [
           {
               "field": "field1",
               "value": "value1-1"
           },
           {
               "field": "field2",
               "value": "value1-2\n"
           }
        ],
        [
           {
               "field": "field1",
               "value": "value2-1"
           },
           {
               "field": "field2",
               "value": "value2-2\n"
           }
        ]
    ]
}

转换为 CSV 输出

"field1","field2"
"value1-1","value1-2\n"
"value2-1","value2-2\n"

然而，当我使用此 jq 命令时，

 cat tmp.json | jq -r '.results | (first | map(.field)), (.[] | map(.value)) | @csv'

我得到这个结果：

"field1","field2"
"value1-1","value1-2
"
"value2-1","value2-2
"

应该如何编写 jq 命令以获得所需的 CSV 结果？

Answer 1

如果换行符是您唯一可以处理的，也许您可以进行字符串替换。

cat tmp.json | jq -r '.results | (first | map(.field)), (.[] | map(.value) | map(gsub("\n"; "\n"))) | @csv'

Answer 2

对于仅 jq 的解决方案，您可以使用 gsub("\n"; "\n")。我会选择这样的东西：

.results
| (.[0] | map(.field)),
  (.[]  | map( .value | gsub("\n"; "\n")))
| @csv

使用您的 JSON 并使用 -r 命令行选项调用它会产生：

"field1","field2"
"value1-1","value1-2\n"
"value2-1","value2-2\n"
