获取发送的curl请求的大小

有没有办法以编程方式获取请求的大小curl？

例如，如果我这样做

curl 'http://www.example.com/url' \
-H 'Cookie: cookie=cookiedata;' \
-H 'X-CSRFToken: csrffake' \
--data 'example=moredata \
--compressed

我想知道我发送的请求有多大？

好吧，经过一番man curl挖掘，我想我已经找到了答案，尽管我不能 100% 确定它的有效性：

 -w, --write-out <format>
     Defines  what  to display on stdout after a completed and successful operation.
     [...]
     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 %%.

     [...]
          size_request   The total amount of bytes
                         that were sent in the HTTP request.

          size_upload    The total amount of bytes that were uploaded.

这意味着添加 a -w '%{size_request} %{size_upload}'，然后在请求后的输出中添加结果数字将为您提供请求的总大小。
