如何在bash上進行字串連接并使用curl將其作為json發送？

這就是我想要開始的作業：

body="\"\:warning\: \:exclamation\: Your pull request is not linked to any issue, please make the corresponding changes in the very first comments body by adding \'Fixes #issue-number\' or \'Resolves #issue-number\'. If your pull request isn\'t linked to any issue, ignore this comment\!\""
echo $body
json="'{\"body\": ${body} }'"
echo $json
statusCode=`curl -X POST -H 'Accept: application/vnd.github json' -H 'Authorization: token ****' -H 'Content-Type: application/json' https://api.github.com/repos/Ismoh/NoitaMP/issues/79/comments -d $json`
echo "statusCode="$statusCode

回聲$體：

$ echo $body
"\:warning\: \:exclamation\: Your pull request is not linked to any issue, please make the corresponding changes in the very first comments body by adding \'Fixes #issue-number\' or \'Resolves #issue-number\'. If your pull request isn\'t linked to any issue, ignore this comment\!"

回聲 $json

$ echo $json
'{"body": "\:warning\: \:exclamation\: Your pull request is not linked to any issue, please make the corresponding changes in the very first comments body by adding \'Fixes #issue-number\' or \'Resolves #issue-number\'. If your pull request isn\'t linked to any issue, ignore this comment\!" }'

GitHub API Docs顯示 json 資料如下：

curl \
  -X POST \
  -H "Accept: application/vnd.github json" \
  -H "Authorization: Bearer <YOUR-TOKEN>" \
  https://api.github.com/repos/OWNER/REPO/issues/ISSUE_NUMBER/comments \
  -d '{"body":"Me too"}'

有人在那里，誰能告訴我我做錯了什么？

有沒有更好的方法來轉義字串以供 json 使用？我已經試過了jq -Rsa .，但也沒有用。

uj5u.com熱心網友回復：

以下是使用 jq 構建 JSON 的方法：

body="\"\:warning\: \:exclamation\: Your pull request is not linked to any issue, please make the corresponding changes in the very first comments body by adding \'Fixes #issue-number\' or \'Resolves #issue-number\'. If your pull request isn\'t linked to any issue, ignore this comment\!\""
json=$(jq -n --arg body "$body" '{ $body }')
# or: json=$(printf '%s\n' "$body" | jq -R '{ body: . }')

我懷疑上面的所有轉義實際上是必要的——為什么要轉義冒號、感嘆號或單引號？但可能是 API 需要參考這些字符；我不明白為什么，因為它消耗 JSON。最好的選擇可能是在分配 body 時去掉上面的所有反斜杠（除了之前的那些"）。

以下是如何正確擴展包含空格的變數，例如將其用作 curl 命令的有效負載時（注意變數周圍的引號）。變數應該總是被參考，除非你知道 110% 你在做什么：

curl -X POST \
 -H 'Accept: application/vnd.github json' \
 -H 'Authorization: token ****' \
 -H 'Content-Type: application/json' \
 https://api.github.com/repos/Ismoh/NoitaMP/issues/79/comments \
 -d "$json"
