Question

想要将json转换为CSV文件。 CSV文件要求每行所有订单项对象1，并且该行还应包含PURCHASEORDERNO。

尝试使用.HEADER []。PURCHASEORDERNO从LINE ARRAY访问HEADER数组的对象PURCHASEORDERNO。但是出现错误jq：错误（在：1）：无法遍历null（空）

JQ命令：-

echo '{"RECEIPT":{"HEADER":[{"LINE":[{"ITEMCODE":"CF7219","QUANTITY":"6"},{"ITEMCODE":"CF7223","QUANTITY":"8"},{"ITEMCODE":"CF7223L","QUANTITY":"8"},{"ITEMCODE":"CF7419","QUANTITY":"6"},{"ITEMCODE":"CF7119","QUANTITY":"3"},{"ITEMCODE":"AP7119/7219L","QUANTITY":"4"},{"ITEMCODE":"CF7620","QUANTITY":"6"},{"ITEMCODE":"HP7313","QUANTITY":"40"}],"SUPPCUSTNAME":"CONFOIL CONTAINERS","SUPPCUSTCODE":"CON001","PROCESSDATE":"20190321","PURCHASEORDERNO":"P6254"},{"LINE":[{"ITEMCODE":"CF7219","QUANTITY":"6"},{"ITEMCODE":"CF7223","QUANTITY":"8"},{"ITEMCODE":"CF7223L","QUANTITY":"8"},{"ITEMCODE":"CF7419","QUANTITY":"6"},{"ITEMCODE":"CF7119","QUANTITY":"3"},{"ITEMCODE":"AP7119/7219L","QUANTITY":"4"},{"ITEMCODE":"CF7620","QUANTITY":"6"},{"ITEMCODE":"HP7313","QUANTITY":"40"}],"SUPPCUSTNAME":"CONFOIL CONTAINERS","SUPPCUSTCODE":"CON001","PROCESSDATE":"20190321","PURCHASEORDERNO":"P6254"}]}}'
 | jq -r '.RECEIPT.HEADER[].LINE[] | ["","ANCPACMEL","ADS",.HEADER[].PURCHASEORDERNO,"",.ITEMCODE,.QUANTITY,"","","","","","","","","","","","","","","","","","","","","","","","","","","",""]|@csv'

错误：-

jq：错误（在1处）：无法遍历null（空）

所需的输出：-

Answer 1

您必须将PURCHASEORDERNO存储在变量中，才能将其添加到每一行。

jq -r '.RECEIPT.HEADER[] | .PURCHASEORDERNO as $pono | .LINE[] | [ $pono, .ITEMCODE, .QUANTITY ] | @csv' input

更新标头：

{
  echo '#Reference,ProductCode,Quantity'
  jq -r '.RECEIPT.HEADER[] | .PURCHASEORDERNO as $pono | .LINE[] | [ $pono, .ITEMCODE, .QUANTITY ] | @csv' input
} > output

通过bash中的JQ命令将JSON转换为CSV
