如何使用命名的多部分主体编写卷曲
How to write a curl with named multipart body
我有一个接受多部分文件的资源，它看起来像这样：
@FormDataParam("file") InputStream inputStream
我想为这个资源写一个curl，但是我不知道如何命名这个参数"file"。
你有什么想法吗？
使用-F开关发送多部分。当你至少使用一个swtich时，Content-Type会自动设置为multipart/form-data。您可以拥有多个。您可以为每个设置一个 <name>=<value> 的值。 <value> 可以通过在值前面使用 @ 来成为一个文件。例如-F "file=@path_to_file"。来自 the manpage
-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 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.
