Xml 无法在curl命令中正确使用变量

我使用的是

curl

命令，它使用了很多变量。这些变量包含XML

我的主要XML文件是：

现在我想将这个XML文件作为变量发送到

curl

命令的

--data

字段

curl -X PUT \
  https://my-end-point \
  -H 'Authorization: Basic <TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '{
  "metadata": "$DATA",
  "id": "$SP_ID"
}'

---

这些解决方案都不起作用。然而，当我使用邮递员应用程序时，它工作得非常好。基本上，我用实际值填充

元数据

，它可以工作。我用

元数据

字段中的实际值复制了

curl

命令，该命令正常工作。但是，当我将该值发送到一个变量并使用该变量时，它就不起作用了。我用尽了一切办法来做这件事。有什么想法吗

哎呀，撤回。你已经试过我的建议了。很抱歉（如果有人想在这里删除我不正确的答案，请删除，或者告诉我如何删除）。

在JSON中转义任意文本的简单方法是使用

jq

。示例会话：

$ DATA='<?xml version="1.0" encoding="UTF-8"?>
> <md:EntityDescriptor'
$ SP_ID=1
$ jq --arg metadata "$DATA" --arg id "$SP_ID" '{"metadata": $metadata, "id": $id}' <<< {}
{
  "metadata": "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<md:EntityDescriptor",
  "id": "1"
}

$DATA='1！'
>在本例中，请包括您所说的“工作”的含义-您是否收到Bash语法错误、4xx或5xx响应，或者其他什么？添加了错误。
curl -X PUT \
  https://my-end-point \
  -H 'Authorization: Basic <TOKEN>' \
  -H 'Content-Type: application/json' \
  -d "{
  \"metadata\": \"${DATA}\",
  \"id\": \"${SP_ID}\"
}"

curl -X PUT \
  https://my-end-point \
  -H 'Authorization: Basic <TOKEN>' \
  -H 'Content-Type: application/json' \
  -d "$( printf '{ "metadata": "%s", "id": "%s" }' \
           "${DATA}" "${SP_ID}" )"

Invalid JSON provided as input.

$ DATA='<?xml version="1.0" encoding="UTF-8"?>
> <md:EntityDescriptor'
$ SP_ID=1
$ jq --arg metadata "$DATA" --arg id "$SP_ID" '{"metadata": $metadata, "id": $id}' <<< {}
{
  "metadata": "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<md:EntityDescriptor",
  "id": "1"
}
