cURL:上传时如何显示进度信息？

Question

我使用以下语法来上传文件:

curl --form upload=@localfilename --form press=OK [URL]

如何显示进度？谢谢。

Answer 1

这是我在我的构建脚本之一中使用的内容:

curl "${UPLOAD_URL}" \
    --progress-bar \
    --verbose \
    -F build="${BUILD}" \
    -F version="${VERSION}" \
    -F ipa="@${IPA};type=application/octet-stream" \
    -F assets="@-;type=text/xml" \
    -F replace="${REPLACE}" \
    -A "${CURL_FAKE_USER_AGENT}" \
    <<< "${ASSETS}" \
    | tee -a "${LOG_FILE}" ; test ${PIPESTATUS[0]} -eq 0

-F和-A您可能对选项不感兴趣，但有用的部分是:

curl "${UPLOAD_URL}" --progress-bar

这告诉 curl在上传过程中显示进度条(而不是默认的“进度表”)，并且:

 | tee -a "${LOG_FILE}" ; test ${PIPESTATUS[0]} -eq 0

将命令的输出附加到日志文件中，并将其回显到 stdout 。 test ${PIPESTATUS[0]} -eq 0部分使得该行(位于 bash 脚本中)的退出状态与 curl 的退出代码相同。命令返回，而不是 tee 的退出状态命令(必需的，因为 tee 实际上是该行中执行的最后一个命令，而不是 curl )。

来自 man curl :

PROGRESS METER
       curl normally displays a progress meter during operations, indicating the
       amount of transferred data, transfer speeds and estimated time left, etc.

       curl  displays  this  data to the terminal by default, so if you invoke curl
       to do an operation and it is about to write data to the terminal, it disables
       the progress meter as otherwise it would mess up the output mixing progress
       meter and response data.

       If you want a progress meter for HTTP POST or PUT requests, you need to
       redirect the response output to a file, using shell redirect (>), -o [file]
       or similar.

       It is not the same case for FTP upload as that operation does not spit out
       any response data to the terminal.

       If you prefer a progress "bar" instead of the regular meter, -# is your
       friend.

OPTIONS
       -#, --progress-bar
              Make curl display progress as a simple progress bar instead of the
              standard, more informational, meter.
