这对我来说很管用:

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

我发现这个问题是因为我想要独立访问响应和内容，以便为用户添加一些错误处理。

Curl允许您自定义输出。您可以打印HTTP状态代码以std输出并将内容写入另一个文件。

curl -s -o response.txt -w "%{http_code}" http://example.com

这允许您检查返回代码，然后决定是否值得打印、处理、记录响应等。

http_response=$(curl -s -o response.txt -w "%{http_code}" http://example.com)
if [ $http_response != "200" ]; then
    # handle error
else
    echo "Server returned:"
    cat response.txt    
fi

%{http_code}是一个由curl代替的变量。你可以做更多的事情，或者发送代码到stderr，等等。参见curl手册和——write-out选项。

-w, --write-out Make curl display information on stdout after a completed transfer. The format is a string that may contain plain text mixed with any number of variables. The format can be specified as a literal "string", or you can have curl read the format from a file with "@filename" and to tell curl to read the format from stdin you write "@-". The variables present in the output format will be substituted by the value or text that curl thinks fit, as described below. All variables are specified as %{variable_name} and to output a normal % you just write them as %%. You can output a newline by using \n, a carriage return with \r and a tab space with \t. The output will be written to standard output, but this can be switched to standard error by using %{stderr}.

我用过这个:

    request_cmd="$(curl -i -o - --silent -X GET --header 'Accept: application/json' --header 'Authorization: _your_auth_code==' 'https://example.com')"

获取HTTP状态

    http_status=$(echo "$request_cmd" | grep HTTP |  awk '{print $2}')
    echo $http_status

为了获得响应体，我使用了这个

    output_response=$(echo "$request_cmd" | grep body)
    echo $output_response

while : ; do curl -sL -w "%{http_code} %{url_effective}\\n" http://host -o /dev/null; done

对于编程使用，我使用以下代码:

curlwithcode() {
    code=0
    # Run curl in a separate command, capturing output of -w "%{http_code}" into statuscode
    # and sending the content to a file with -o >(cat >/tmp/curl_body)
    statuscode=$(curl -w "%{http_code}" \
        -o >(cat >/tmp/curl_body) \
        "$@"
    ) || code="$?"

    body="$(cat /tmp/curl_body)"
    echo "statuscode : $statuscode"
    echo "exitcode : $code"
    echo "body : $body"
}

curlwithcode https://api.github.com/users/tj

显示如下信息:

statuscode : 200
exitcode : 0
body : {
  "login": "tj",
  "id": 25254,
  ...
}

要获得响应代码和响应:

$ curl -kv https://www.example.org

要得到响应代码:

$ curl -kv https://www.example.org 2>&1 | grep -i 'HTTP/1.1 ' | awk '{print $3}'| sed -e 's/^[ \t]*//'

2>&1:错误存储在输出中，用于解析 Grep:从输出中过滤响应代码行 Awk:从响应代码行中过滤响应代码 Sed:删除前导空白
