Question

我们如何在终端上获取带有curl的POST 请求消息？

如果我是对的，这就是我们获得回复消息的方式：

$ curl -X POST -d "param1=value1&param2=value2" 'http://example.com' -i
HTTP/1.1 200 OK
Date: Fri, 13 Sep 2019 01:51:22 GMT
Server: Apache/2.4.38 (Ubuntu)
Content-Length: 56
Content-Type: text/html; charset=UTF-8

Array
(
    [param1] => value1
    [param2] => value2
)

我们如何在下面得到类似的东西？

POST /path HTTP/1.1
Host: example.com

foo=bar&baz=bat

使用-v：

$ curl -X POST -d "param1=value1&param2=value2" 'http://127.0.0.1' -v

* Expire in 0 ms for 6 (transfer 0x5591f30695c0)
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Expire in 200 ms for 4 (transfer 0x5591f30695c0)
* Connected to 127.0.0.1 (127.0.0.1) port 80 (#0)
> POST / HTTP/1.1

> User-Agent: curl/7.64.0
> Accept: */*
> Content-Length: 27
> Content-Type: application/x-www-form-urlencoded

< HTTP/1.1 200 OK
< Date: Fri, 13 Sep 2019 01:41:44 GMT
< Server: Apache/2.4.38 (Ubuntu)
< Content-Length: 56
< Content-Type: text/html; charset=UTF-8
<
Array
(
    [param1] => value1
    [param2] => value2
)
* Connection #0 to host 127.0.0.1 left intact

但是看不到没有请求消息。
