Form Support in LRest
Most of the time, I would prefer to post
JSON data as
Content-Type, since I can make client code simple yet powerful. It is easier to deal with nesting, encoding, type-casting with
application/json, however when it comes to file uploading, we’ll have to encode the binary data in order to put it in a JSON object, and format like base64 encoding will make the
HTTP payload bigger. If we do care about performance here, we may use
Recently I added multipart/form support in
LRest. It’s still in the early stage but the goal is still to keep it easy to use. Here is an example:
In this case,
LRest.content.form replaces the default content_type, which is
LRest.content.json (I’ll change it to enum later since it’s better supported in
Swift), and key/data pairs are assigned to the client itself directly. Currently the data type is hard-coded as
image/jpeg which should be set by user, or determined by
Parameter support is not as good as JSON either.
Array objects cannot be nested, and value.description is used for all the other objects. It’s not hard to fix these issues, and I’ll start working on them when it’s needed.
