在bash脚本中使用curl并获取curl

本文介绍了在bash脚本中使用curl并获取curl:(3)在URL中发现非法字符的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

所以我有一个非常简单的bash脚本,正在curl'ing到一个头的auth服务器。头url被写入var,然后在下一个curl调用中使用。当在第一次curl调用中使用var set时,我得到curl:(3)URL中发现非法字符。我可以回应var和所有看起来不错,我甚至能重置var(在我的例子下面)和它的工作原理。



脚本

  URL = $(curl -i -X GET -HX-Auth-User:MyUserna, e-HX-Auth-Key:MyAPIKeyhttps://urlToAuthServer.tld/auth/v1.0/| grepX-Storage-Url:| awk'{print $ 2}')

curl -X GET -HX-Auth-Token:MyAuthTok$ {URL} /folder/myfile.txt-o ./myfile.txt



运行上面的示例时,我获得:

  curl:(3)在URL中找到非法字符

网址var看起来像这样(无非法字​​符)

  https://somesecureurl.com/auth/AUTH_67383834 -45245453-g34g34t5-34534 

当我在终端中这样做:

现在我复制并粘贴字符串并将其重新设置为URL(再次全部在终端):

 > $ URL =https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534
> $ curl -X GET -HX- Auth-Token:MyAuthTok$ {URL} /folder/myfile.txt-o ./myfile.txt


$ b因此,为什么我在第一个例子中得到curl:(3)URL中发现的非法字符错误?



更新
我这样做:
printf%s$ URL| xxd



以下是输出(已解决的地址改变了你的想法)

解决方案

$ URL包含 \r (CR)( 0d )。删除它

  URL = $ {URL%$'\r'} 

之前使用 curl


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.

The Bash script

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

When running the above example I get:

curl: (3) Illegal characters found in URL

The URL var looks like this (no illegal chars)

https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534

When I do this in terminal it works:

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

It works.

So why am I getting the "curl: (3) Illegal characters found in URL" error in the first example?

UpdateI ran this:printf %s "$URL" | xxd

Here is the output (addressed changed up you get the idea)

0000000: 6874 7470 733a 2f2f 6461 6c30 352e 6f62  https://server.ob

0000050: 6166 3331 6232 0d                        ag11c8.
解决方案

The $URL contains a \r (CR) at the end (0d). Remove it with

URL=${URL%$'\r'}

before using it with curl.
