Linux 基础命令-CURL 表单上传文件
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
If filename/path contains ',' or ';', it must be quoted by double-quotes like:
curl -F "file=@\"localfile\";filename=\"nameinpost\"" url.com
or
curl -F 'file=@"localfile";filename="nameinpost"' url.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.
