在 curl 响应正文的末尾自动添加换行符 [英] Automatically add newline at end of curl response body

问题描述

如果 curl 请求的 HTTP 响应正文不包含尾随换行符，我最终会遇到这种非常烦人的情况，其中 shell 提示位于行的中间，并且转义很混乱，以至于当我把屏幕上的最后一个 curl 命令，从该 curl 命令中删除字符会删除错误的字符.

If the HTTP response body for a curl request doesn't contain a trailing newline, I end up with this really annoying condition where the shell prompt is in the middle of the line, and escaping is messed up enough that when I put the last curl command on the screen, deleting characters from that curl command deletes the wrong characters.

例如:

[root@localhost ~]# curl jsonip.com
{"ip":"10.10.10.10","about":"/about"}[root@localhost ~]#

有没有什么技巧可以让我在 curl 响应的末尾自动添加换行符，让提示回到屏幕的左边缘?

Is there a trick I can use to automatically add a newline at the end of a curl response, to get the prompt back on the left edge of the screen?

推荐答案

来自 man 文件:

为了更好地让脚本程序员了解开发进度curl，引入了 -w/--write-out 选项.使用它，您可以指定您想从上次传输中提取哪些信息.

To better allow script programmers to get to know about the progress of curl, the -w/--write-out option was introduced. Using this, you can specify what information from the previous transfer you want to extract.

显示下载的字节数以及一些文本和结束换行:

To display the amount of bytes downloaded together with some text and an ending newline:

curl -w 'We downloaded %{size_download} bytes
' www.download.com

因此尝试将以下内容添加到您的 ~/.curlrc 文件中:

So try adding the following to your ~/.curlrc file:

-w "
"
