Question
I have made several apis in djangorestframework. This I could test both with the html form of the api as with curl in commandline.
Now I have an api to a Model with one off the fields an ImageField.
I can't figure out which curl command to use. Using the syntax I used before fot post actions in json format, it would be:
curl -X POST -S -H 'Content-Type: application/json' -u "username:password" --data-binary '{"otherfields":"something", "photo":"/home/michel/test.jpg"}' 127.0.0.1:8000/api/v1/
but in this case the photo will not be saved and left empty (the photo is an optional field)
adding -T /home/michel/test.jpg
I get an error message saying 127.0.0.1:800/api/v1/test.jpg does not exist as an url.
In the test html form of djangorestframework, all works fine.
Using the -F
option, it says I can only do 1 request at a time...
I also removed the datatype from data-binary
Can anybody help me how to make this curl post with both the image and the other data in json in 1 command.
Solution
After a long puzzle, this seems to do the trick:
- put all json arguments in separate
-F
arguments - only use the header
Accept
(notContent-Type
) - And specify the image type
Use
@
to indicate the local file to uploadcurl -X POST -S \ -H 'Accept: application/json' \ -u "username:password" \ -F "otherfields=something" \ -F "photo=@/home/michel/test.jpg;type=image/jpg" \ http://127.0.0.1:8000/api/v1/
By the way, I know all of this is on the documentation site of curl, but just missed an example of all those things together since there are a lot of options to try out.
