使用jq在循環中將json對象卷曲為json數組文件中的POST數據

Question

這是我的示例test.json文件

[
    {
        "description": "Some description",
        "name": "Some name",
        "summary": "Some summary. "
    },
    {
        "description": "Some description",
        "name": "Some name",
        "summary": "Some summary. "
    },
    {
        "description": "Some description",
        "name": "Some name",
        "summary": "Some summary. "
    }
]

這是bash腳本

declare -A values=( )
while IFS= read -r value; do
  echo "Read  $value" >&2
  #echo $value | curl -d @- -H "Content-Type: application/json" https://example.com/api/foo
done < <(jq -r '.[]' <$1)

這是我得到的輸出

Read {
Read    "description": "Some description",
Read    "name": "Some name",
Read    "summary": "Some summary. "
Read }
Read {
Read    "description": "Some description",
Read    "name": "Some name",
Read    "summary": "Some summary. "
Read }
Read {
Read    "description": "Some description",
Read    "name": "Some name",
Read    "summary": "Some summary. "
Read }

我想使用文件中的JSON對象，以使用curl將數據發布到API。 我希望循環運行三遍。

如何獲取整個JSON對象（導致循環運行3次），而不是從test.json文件輸出每一行？

Answer 1

使用jq -c在單獨的行上發出每個結果。 當您的預期輸出為JSON而非原始字符串時， 請勿使用-r 。

我還在下面添加了一些引號，您的代碼中沒有這些引號：

# for readability, factored out
args=( -d @- -H "Content-Type: application/json"  )

while IFS= read -r value; do
  echo "Read  $value" >&2
  curl "${args[@]}" https://example.com/api/foo <<<"$value"
done < <(jq -c '.[]' <"$1")
