问题描述
所以我有一个非常简单的 bash 脚本,它可以卷曲到身份验证服务器以获取标头.标头 url 被写入一个 var,然后在下一个 curl 调用中使用.在第一个 curl 调用中使用 var 设置时,我收到curl: (3) Illegal characters found in URL".我能够回显 var 并且一切看起来都不错,我什至可以重置 var(在下面的示例中)并且它可以工作.
So I have a very simple bash script that is curl'ing to an auth server for a header. The header url is written to a var and then used in the next curl call. When using the var set in the first curl call I am getting "curl: (3) Illegal characters found in URL". I am able to echo the var and all looks good, I am even able to reset the var (in my example below) and it works.
Bash 脚本
URL=$(curl -i -X GET -H "X-Auth-User: MyUserna,e" -H "X-Auth-Key: MyAPIKey" "https://urlToAuthServer.tld/auth/v1.0/" | grep "X-Storage-Url:" | awk '{print $2}')
curl -X GET -H "X-Auth-Token: MyAuthTok" "${URL}/folder/myfile.txt" -o ./myfile.txt
运行上面的例子时,我得到:
curl: (3) Illegal characters found in URL
URL var 看起来像这样(没有非法字符)
https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534
当我在终端中执行此操作时,它会起作用:
$ URL=$(curl -i -X GET -H "X-Auth-User: MyUserna,e" -H "X-Auth-Key: MyAPIKey" "https://urlToAuthServer.tld/auth/v1.0/" | grep "X-Storage-Url:" | awk '{print $2}')
$ echo $URL
$ echo $URL
https://somesecureurl.com/auth/AUTH_67383834-45245453-g543-g34/a>
https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534
现在我复制并粘贴字符串并将其重新分配到 URL 像这样(再次全部在终端中):
Now I copy and paste the string and reasign it to URL like so (again all in terminal):
>$ URL="https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534"
>$ curl -X GET -H "X-Auth-Token: MyAuthTok" "${URL}/folder/myfile.txt" -o ./myfile.txt
那么为什么我会在第一个示例中收到curl: (3) Illegal characters found in URL"错误?
So why am I getting the "curl: (3) Illegal characters found in URL" error in the first example?
Here is the output (addressed changed up you get the idea)

推荐答案
The $URL contains a (CR) at the end (
0d
). Remove it with
URL=${URL%$'
'}
