脚本的第一部分如下所示:
curl -k -X POST -H "Content-Type: application/x-www-form-urlencoded" -H "Cache-Control: no-cache" -d 'username=username&password=password "https://get_token" >> token.txt
token=$(<'token.txt'$'\r')
echo "$token"
echo $token 的输出看起来不错(417 个字符):

让我们看看当我尝试将 token 插入脚本的下一部分时会发生什么。
echo curl -k -X POST -H "Content-Type: application/json" -H "Authorization: AR-JWT "$token"" -H "Cache-Control: no-cache" -d '{
"values":{
"First_Name": "John",
"Last_Name": "Doe",
}
} ' "https://randomurl.com"
这是输出:

}

2 传递 token 时发生的事情
删除 token 中的“9IiwibmJmIjoxNDgzOTg5NjgwLCJpc3Mi”
token 的第二部分(删除部分之后)被插入正文
我尝试过的:
- 使用不同的 token
- 使用 token 而不先将其传递到文件中
- 将授权 header 移到 URL 之前
所有这些都会导致相同的行为。
我在 Windows 7 上使用 cygwin64 当第二个 cURL 命令在正确的空间中用完整的标记输入到 cygwin 中时，它没有问题
将 set-x 添加到脚本时的输出:
$ ./variable_testing.sh
+ ./variable_testing.sh

最佳答案
首先:您的 token 目前在其中包含字面 CR——明显的屠杀是由这些 CR 打印在您的 echo 输出中引起的，将光标移回行首，因此部分您的 token 被以后的内容覆盖。要消除它们，您可以将文件转换为 UNIX 文本格式(并确保在生成该文件的任何命令中都没有 CR)，或者您可以使用:
token=$(<token.txt) # read token.txt into "token" variable
token=${token//$'\r'/} # strip CRs from token variable
如果您想将 Authorization header 作为单个单词传递给 curl，请不要结束并重新初始化您的引号；将单个参数保留在一组句法引号中。
-H "Authorization: AR-JWT $token"
最后，确保您的脚本本身是 UNIX 格式——您的编辑器没有使用 DOS 换行符保存它。
关于Bash 变量在插入到 cURL 命令中时被屠杀，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41556332/
