从 Curl 输出中提取 Json 字段值以及 HTTP 响应

Question

我正在尝试编写一个 Bash 脚本，其中在本地服务器上托管的应用程序上触发了以下给定的 curl，我需要从 curl 响应中提取以下值并将它们存储在单独的变量中：

1) HTTP 响应代码，即。 201 2）ETag值：即。 292a74f6-6999-403c-bc3c-d78af9d98a2a 3）来自json响应的“sub”的值，即。 11deadd1-ca08-4995-aa4b-a980307f2b1d

`curl -X POST  -v -sS http://localhost:8087/idp-backend/profile/   -H 'accept: application/json'   -H 'content-type: application/json'   -H 'x-int-opco-id: NV'   -d '{"user_details": {

` 我正在尝试将 curl 响应存储在名为 content 的变量中并尝试执行 echo $content | jq -r '.[] .sub.

但是，这是行不通的，而且即使是 HTTP 响应和 Etag 值也不是 Json Body 的一部分，所以我如何编写 bash 脚本以便能够存储上述所有 3 个值（http , Etag & sub) 一次拍摄不同的变量。

提前致谢。

Answer 1

您可以 grep 输出，因为它显示为标准输出，并使用 -P 和 -o 标志之类的东西来获取您想要的部分。
-P（或 --perl-regexp）允许您 grep 查找与您的正则表达式匹配的任何内容，并且当与 -o（或 --only-matching）一起使用时，您可以非常具体地说明您想要回显的内容。

例如，在 curl 末尾添加 | grep -Po '(?i)(?<http>^< http.*$)' 将返回以不区分大小写的 < http 开头的行 blake.payne tmp $ 猫测试 | grep -Po '(?i)(?^ 从你的例子中我得到了以下信息：

< HTTP/1.1 100 < HTTP/1.1 201
