Hi all
Rodric, Carlos and myself had a discussion this afternoon about what should
happen when the implements an HTTP web action that doesn't provide all the
details required for sending a fully formed HTTP message back the client.
As a refresher, when implementing an HTTP web action, you need to return three
top level keys: statusCode, headers and body, for example:
return {
statusCode: 201,
headers: { "Content-Type": "application/xml" },
body: "<xml>Created</xml>"
}
There is also some magic for application/json where you can send back a JSON
dictionary as the body and OpenWhisk will handle it for you:
return {
statusCode: 201,
headers: { "Content-Type": "application/json" },
body: { "foo" : { "bar" : "baz" } }
}
Questions arise as to what to do if some of this is missing. e.g.
return {
body: "hello"
}
Clearly to send a result back to the client, OpenWhisk needs to provide a
status code and set a content type. What should it do?
Issue [2674] [1] contains a suggestion of what we think it should do. If you're
interested, now is a good time to comment.
Regards,
Rob...
