bash - 在循环中使用 jq 将 json 对象作为 json 数组文件中的 POST 数据

Question

这是我的示例 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. "
    }
]

这是 bash 脚本

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)

这是我得到的输出

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 对象，使用 curl 将数据发布到 API。我希望循环运行 3 次。

如何获取整个 JSON 对象(导致循环运行 3 次)而不是从 test.json 文件中输出每一行？

Answer 1

使用 jq -c，在单独的行上发出每个结果。当您的预期输出是 JSON 而不是原始字符串时，不要使用-r。

我还在下面添加了一些您的代码中缺少的引号:

# 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")
