如何使用curl将数据和响应头都保存到变量

Linux文章/教程评论75阅读模式

我有一个带有curl request的sh脚本,它将响应保存到data变量:

data=$(curl -X GET -H "Authorization: Bearer dee52f918f769f9734599526a296a0d" -H "Accept: application/json" -H "Cache-Control: no-cache" http://someurl.com/data)

我建议打开终端并运行以下命令:文章源自爱尚资源教程网-https://www.23jcw.net/2589.html
