Linux CURL how to POST file and data url encoded same time?

Question

I have a problem to send a POST request with a text file and some key=value (value contains special characters and it needs to be encoded, e.g: query=select c + a % b).

I've tried like this and it returns error Warning: You can only select one HTTP request!

curl -F "file=@path_to_text_file" 
--data-urlencode "query=select c + a % b" "http://localhost:8082/app"

remove --data-urlencode then it can run but the value of query is not encoded.

I prefer to not need to encode query manually.

@DmitriChubarov these topics only contain key=value which doesn't have the special characters. — Bằng Rikimaru

The accepted answer at stackoverflow.com/a/19148720/1328439 should solve it for you. To encode the query string use urllib.urlencode() — Dima Chubarov

@DmitriChubarov this is not what I wanted to use an external tool to encode, thanks though. — Bằng Rikimaru

You can specify exactly one content-type for one POST request. It can be either application/x-www-form-urlencoded, or multipart/form-data or text/plain but you have to use only one. For your command curl was complaining that you are trying to specify both form-urlencoded and multipart/form-data. — Dima Chubarov

This will do the upload then send the post request

curl -F "file=@path_to_text_file" "http://localhost:8082/app" --next --data-urlencode "query=select c + a % b" "http://localhost:8082/app"

unfortunately, the --next parameter only exists since version 7.36. In Centos 7, it is version 7.29 only.
