json输出：

  ],
  "success": true,
  "errors": [],

    }
  }
}

我希望在同一行输出的内容，例如：

.id,.redirect.source_url,.redirect.target_url,.cursors_after

fcf9728ed6e94078bae9ffe200bf1054,www.123.com/123,https://www.123.com/xxx fcf9728ed6e94078bae9ffe200bf1054,www.123.com/123,https://www.123.com/xxx fcf9728ed6e94078bae9ffe200bf1054,www.123.com/123,https://www.123.com/xxx

标签： line jq

【解决方案1】：

构建要输出的字符串，然后使用-r 命令行按原样发出该字符串（而不是作为 JSON 文字）。

jq -r '
   .result[] |
   [
      .id,
      .redirect.source_url,
      .redirect.target_url,
      .cursors_after
   ] |
   @csv
' json

输出

"fcf9728ed6e94078bae9ffe200bf1054","www.1234.com/acssurgerynews/article/248345/transgender-health/detransitioners-received-poor-evaluation-when","https://www.1234.com/viewarticle/962270",
"fac3ab84691b44219c270a5dd073e374","www.1234.com/advanced-and-metastatic-breast-cancer/article/248363/breast-cancer/liquid-biopsy-metastatic-breast","https://www.1234.com/viewarticle/942277",
"0ae189027c574eedac22f854b4676568","www.1234.com/advanced-and-metastatic-breast-cancer/article/249807/breast-cancer/evolving-her2-metastatic-breast","https://www.1234.com/viewarticle/963856",

【讨论】：

这适用于单条记录，但多条记录将全部出现在一行中，最后带有逗号。我已经编辑了这个问题。
@user2193480，您需要显示更多输入数据
更好的是如何从输出中删除引号和结束逗号？
如果您想要 CSV 以外的其他内容，请随时调整
没有尾随逗号，而是尾随空白字段。您说您希望 .cursors_after 作为最后一个字段，但您的数据中缺少它，因此您最终得到一个空白字段。

【解决方案2】：

您可以为每个包含您的值的条目构建一个新数组，然后使用join(",") 将所有值连接到一行。 -r/--raw-output 省略顶级字符串周围的引号：

jq -r '.result[]
| [.id,.redirect.source_url,.redirect.target_url,.cursors_after]
| join(",")'
``

The difference between `join/1` and `@csv` filters is that `@csv` will escape any embedded commas in the value and automatically wrap all strings in quotes. `join` does not do any escaping and does not add quotes around strings.
