curl -F 是什么意思？php instagram

Question

我想弄清楚这是什么意思？我希望能够向 Instagram 的 API 发布一些内容，但不确定 curl -F 是什么意思？我尝试在谷歌上搜索它，但它没有给我太多。也许有这件事的人可以发光？

另外，使用这种方法发布到 Instagram 的最佳方式是什么？文档要求

curl -F 'access_token=ACCESS-TOKEN' \
    https://api.instagram.com/v1/media/{media-id}/likes

谁可以给我解释一下这个？

提前致谢！

来自man curl：

   -F, --form <name=content>
          (HTTP) This lets curl emulate a filled-in form in
          which a user has pressed the submit button. This
          causes curl to POST data using the Content-Type
          multipart/form-data according to RFC 2388. This
          enables uploading of binary files etc. To force the
          'content' part to be a file, prefix the file name with
          an @ sign. To just get the content part from a file,
          prefix the file name with the symbol <. The difference
          between @ and < is then that @ makes a file get
          attached in the post as a file upload, while the <
          makes a text field and just get the contents for that
          text field from a file.

          Example, to send your password file to the server,
          where 'password' is the name of the form-field to
          which /etc/passwd will be the input:

          curl -F password=@/etc/passwd www.mypasswords.com

          To read content from stdin instead of a file, use - as
          the filename. This goes for both @ and < constructs.

          You can also tell curl what Content-Type to use by
          using 'type=', in a manner similar to:

          curl -F "web=@index.html;type=text/html" url.com

          or

          curl -F "name=daniel;type=text/foo" url.com

          You can also explicitly change the name field of a
          file upload part by setting filename=, like this:

          curl -F "file=@localfile;filename=nameinpost" url.com

          See further examples and details in the MANUAL.

          This option can be used multiple times.

curl是一个模拟 Web 请求的 Linux 实用程序。发出curl -F命令会发出带有表单提交数据的 http 请求。在这种情况下，表单数据就是数据access_token=ACCESS-TOKEN，它被发送到 urlhttps://api.instagram.com/v1/media/{media-id}/likes
