Curl command top upload file with metadata

Question

I am testing my RESTFul API, and i would like to know if there is a way to upload a file and json data at the same time.

When i run this command from command line:

curl -v -X POST -d '{"label":"vacations", "date":"2011-01-03"}' -F photo=@"photo.png" http://localhost/album

I get this error: Warning: You can only select one HTTP request!

Is there really a way to accomplish this?

can i also use @sputnick approach to upload audio files with metadata? — wguerrero, Mar 12 '13 at 18:31
Sure wguerrero, you can upload any binary you want with this method. — Gilles Quénot, Mar 12 '13 at 22:13

It seems that you have a conflict between

-F photo=@"photo.png"

and

-d '{"label":"vacations", "date":"2011-01-03"}'

you may use only one of this 2 options.

The best approach I think is to base64 encode the picture in a string and put it in your JSON like :

-d '{"label":"vacations", "date":"2011-01-03", "photo":"AE..."}'

and base64 decode it server side.

You can add this switch too :

-H 'Content-type:text/json'

Thank you. Do you know an online service where i can encode files? i mean where the files encoded are valid. – wguerrero Mar 12 '13 at 17:44
Which OS do you use ? On linux, I can use `base64 file` – Gilles Quénot Mar 12 '13 at 17:46
wow, i test it, but it is a very long ouptut, won't this cause any possible issue?? – wguerrero Mar 12 '13 at 17:51
No, that's not an issue. POST have a high limit compared to GET method. If you have a better way, come here later to tell us how ;) – Gilles Quénot Mar 12 '13 at 17:58

@sputnick aproach works :).

I'll use postman (a chrome extension) to test my restful API instead of curl.

you can also use -F for the metadata, see Erik Allik's answer here

something like for example:

curl -F 'json={"label":"vacations", "date":"2011-01-03"}' -F 'photo=@photo.png' http://localhost/album
