如何处理循环中的 curl 请求

Question

我有循环发送 curl 请求的 bash 脚本。第一次迭代工作正常，但第二次有像

curl: (6) Could not resolve host:key1, Error: Process completed with exit code 6.

这样的错误

我的代码看起来像

IFS=',' read -ra keys <<< "key1, key2, key3, key4, key5"
for key in "${keys[@]}"
do
  echo "Deleting cache for key: $key"
  response=$(curl -X DELETE \
                  -H "Accept: application/vnd.github+json" \
                  -H "Authorization: Bearer GITHUB_TOKEN"\
                  -H "X-GitHub-Api-Version: 2022-11-28" \
                  https://api.github.com/repos/OWNER/REPOSITORY/actions/caches?key=$key)
  if [ $? -ne 0 ]; then
    echo "Error occurred while deleting key $key"
    continue
  fi
  echo "Response for key $key: $response"
done

我该如何解决这个问题

Answer 1

你声明数组的方式有误，检查：

IFS=',' read -ra keys <<< "key1, key2, key3, key4, key5"
echo "[${keys[1]}]"
[ key2]

您的钥匙中有前导不需要的空间

Answer 2

您的列表/数组在每个 KEY 前面引入一个空格....尝试添加：

IFS=',' read -ra keys <<< "key1, key2, key3, key4, key5"
for key in "${keys[@]}"
do
  key=$(echo -n "$key"|xargs) ## <---- cleanup spaces
  echo "Deleting cache for key: $key"
  response=$(curl -X DELETE \
                  -H "Accept: application/vnd.github+json" \
                  -H "Authorization: Bearer GITHUB_TOKEN"\
                  -H "X-GitHub-Api-Version: 2022-11-28" \
                  https://api.github.com/repos/OWNER/REPOSITORY/actions/caches?key=$key)
  if [ $? -ne 0 ]; then
    echo "Error occurred while deleting key $key"
    continue
  fi
  echo "Response for key $key: $response"
done
