Question

我正在尝试向vcloud导演api做cURL。从终端尝试时，这完全正常，但在使用变量替换的bash脚本中尝试时失败。

这是我的脚本无效：

以下工作正常：

token=" valid token"
URL="vcdurl"
auth_header=\"x-vcloud-authorization:${token}\"
curl -i -k -H "Accept:application/*+xml;version=1.5" -H "${auth_header}" -X GET $URL/api/vdc/7f252c90-eb3b-43c4-a5ef-458e5bf22c0e > test.txt
echo `cat text.txt`

Error :HTTP/1.1 400 Bad Request
Connection: close

花了几天才弄明白，但我被困在这里。

Answer 1

token=" valid token"
url="https://vcdurl"
auth_header=x-vcloud-authorization:${token}

curl -i -k -X GET \
  -H "Accept:application/*+xml;version=1.5" \
  -H "${auth_header}" \
  "$url/api/vdc/7f252c90-eb3b-43c4-a5ef-458e5bf22c0e" \
  | tee test.txt

请注意：

已将一个前导https://添加到网址变量的定义中，以使其与手动输入的工作命令保持一致。
我们引用了$URL的扩展。（另请注意对小写的更改;请参阅POSIX conventions for environment variable names - 因为shell变量与环境变量共享命名空间，遵守这些约定可避免与对系统或shell有意义的环境变量发生冲突。
我们不再将文字引号注入auth_header。（与由shell解析的语法引号不同， literal 引号被视为数据，因此传递给curl）。
（非常错误）echo $(cat test.txt)消失了。（顺便说一下，这是一种理智的写作方式cat test.txt;即使echo "$(cat test.txt)"会消除最糟糕的不良行为; printf '%s\n' "$(<test.txt)"会更好，避免需要一个子shell 或一个外部实用程序[因为cat没有内置到shell本身，因此有调用的开销]）。

内部脚本中的CURL无法正常使用VCD api
