| 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 an image to a server, where \&'profile' is the name of the |
| form-field to which portrait.jpg will be the input: |
| |
| curl -F profile=@portrait.jpg https://example.com/upload.cgi |
| |
| To read content from stdin instead of a file, use - as the filename. This goes |
| for both @ and < constructs. Unfortunately it does not support reading the |
| file from a named pipe or similar, as it needs the full size before the |
| transfer starts. |
| |
| 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" example.com |
| |
| or |
| |
| curl -F "name=daniel;type=text/foo" example.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" example.com |
| |
| If filename/path contains ',' or ';', it must be quoted by double-quotes like: |
| |
| curl -F "file=@\\"localfile\\";filename=\\"nameinpost\\"" example.com |
| |
| or |
| |
| curl -F 'file=@"localfile";filename="nameinpost"' example.com |
| |
| Note that if a filename/path is quoted by double-quotes, any double-quote |
| or backslash within the filename must be escaped by backslash. |
| |
| See further examples and details in the MANUAL. |
| |
| This option can be used multiple times. |
