bash（带HTTPie）使用什么output？
[英]What output is used in bash (with HTTPie)?
问题描述
I'm trying to analyze this command:
我正在尝试分析此命令：
$ http :"/hello"
HTTP/1.1 401 Unauthorized
<headers>
<body>
I'm trying to save the whole thing in a variable VAR=$(... ) but to no avail so far.我试图将整个内容保存在变量VAR=$(... )中，但到目前为止无济于事。
If I run如果我跑
$ http :"/hello" 1>/dev/null
everything disappear, so I derive that everything is standard output.一切都消失了，所以我得出一切都是标准的 output。
But if I try to send this to a file or to my variable, I don't see the initial portion.但是，如果我尝试将其发送到文件或我的变量，我看不到初始部分。 So I thought this was stderr , so I did 2>&1 but this doesn't have any effect either.所以我认为这是stderr ，所以我做了2>&1但这也没有任何效果。
How can I go about understanding this?我怎么能理解这个？
Thanks谢谢

HTTPie alters its output, depending on whether it is writing to the terminal or a regular file. HTTPie 会更改其 output，具体取决于它是写入终端还是常规文件。
From the manual从手册
Redirected output
HTTPie uses a different set of defaults for redirected output than for terminal output.
Formatting and colors aren't applied (unless
--prettyis specified).--pretty）。 Only the response body is printed (unless one of the output options is set).[...]
There are specific command line options you can use to override the defaults.您可以使用特定的命令行选项来覆盖默认值。

You could try using option "-v" and "-o" to capture both headers and body in a file, as in:您可以尝试使用选项“-v”和“-o”来捕获文件中的标题和正文，如：
http -v -o output.file "google.com/bla"
As mentioned by @chepner in the comment, some tools detect if stdout is a file or not and change what they output.正如@chepner 在评论中提到的那样，一些工具检测标准输出是否是文件并更改它们 output 的内容。
Edit: to work easiest as you wanted (to stdout) you can use:编辑：为了你想要的最简单的工作（到标准输出），你可以使用：
http -v -o /dev/stdout "google.com/bla"
