哇，这么多答案，cURL开发人员肯定把它留给了我们作为家庭练习:)好吧，这是我的想法-一个脚本，使cURL工作，因为它应该是，即:

像cURL那样显示输出。 如果HTTP响应代码不在2XX范围内，则使用非零代码退出

保存为curl-wrapper.sh:

#!/bin/bash

output=$(curl -w "\n%{http_code}" "$@")
res=$?

if [[ "$res" != "0" ]]; then
  echo -e "$output"
  exit $res
fi

if [[ $output =~ [^0-9]([0-9]+)$ ]]; then
    httpCode=${BASH_REMATCH[1]}
    body=${output:0:-${#httpCode}}

    echo -e "$body"

    if (($httpCode < 200 || $httpCode >= 300)); then
        # Remove this is you want to have pure output even in 
        # case of failure:
        echo
        echo "Failure HTTP response code: ${httpCode}"
        exit 1
    fi
else
    echo -e "$output"
    echo
    echo "Cannot get the HTTP return code"
    exit 1
fi

所以它就像往常一样，但不是curl do ./curl-wrapper.sh:

所以当结果在200-299范围内时:

./curl-wrapper.sh www.google.com 
# ...the same output as pure curl would return...
echo $?
# 0

当结果超出200-299范围时:

./curl-wrapper.sh www.google.com/no-such-page
# ...the same output as pure curl would return - plus the line
#    below with the failed HTTP code, this line can be removed if needed:
#
# Failure HTTP response code: 404
echo $?
# 1

只是不要传递“-w|——write-out”参数，因为这是脚本中添加的内容

在末尾追加一行“http_code:200”，然后grep关键字“http_code:”并提取响应代码。

result=$(curl -w "\nhttp_code:%{http_code}" http://localhost)

echo "result: ${result}"   #the curl result with "http_code:" at the end

http_code=$(echo "${result}" | grep 'http_code:' | sed 's/http_code://g') 

echo "HTTP_CODE: ${http_code}"  #the http response code

在这种情况下，您仍然可以使用非静默模式/ verbose模式来获取有关请求的更多信息，例如curl响应体。

详细模式会告诉你一切

curl -v http://localhost

这对我来说很管用:

curl -Uri 'google.com' | select-object StatusCode

-i选项是你想要的:

curl -i http://localhost

在输出中包含协议头(H/F)

或者你可以使用verbose选项:

curl -v http://localhost

-v，——verbose使操作更健谈

我使用以下方法在控制台中获得返回代码和响应体。

注:使用tee将输出附加到一个文件以及控制台，这解决了我的目的。

示例CURL调用供参考:

curl -s -i -k --location --request POST ''${HOST}':${PORT}/api/14/project/'${PROJECT_NAME}'/jobs/import' \
--header 'Content-Type: application/yaml' \
--header 'X-Rundeck-Auth-Token: '${JOB_IMPORT_TOKEN}'' \
--data "$(cat $yaml_file)" &>/dev/stdout | tee -a $response_file

return_code=$(cat $response_file | head -3 | tail -1 | awk {'print $2'})

if [ "$return_code" != "200" ]; then
  echo -e "\Job import api call failed with rc: $return_code, please rerun or change pipeline script."
  exit $return_code
else
  echo "Job import api call completed successfully with rc: $return_code"
fi

希望这能帮助到一些人。
