Noob question: "function X does not accept keyword arguments" error

[digeratus]

Hi @tanmaykm and rest of contributors,

Julia noob here! Trying to create a prototype based on your example. Only difference is that I'd like to have a function that adds to an existing array InfoncastSoundFiles.

I get a "function does not accept keyword arguments" error from APIResponder if I'm understanding the error stack correctly. I believe I'm not configuring the create_responder function properly, but it could just be a syntax error elsewhere. Please advise.

Thanks,
Jose

Take a look at my srvr.jl and httpsrvr.jl:

using Dates
using JuliaWebAPI

mutable struct SoundFile
    title::String
    creator::String
    date::String
    tags::Array
    URL::String
end

#Let's see how this wwould work if this is not a const
#const InfoncastSoundFiles = SoundFile[
const InfoncastSoundFiles = SoundFile[
  SoundFile("Fur Elise", "Ludwig Beethoven","12202019",["mp3","song", "music"],"https://URL Here"),
  SoundFile("Fidelio", "Ludwig Beethoven","11032011",["song", "dance"],"https://URL Here"),
  SoundFile("Missa Solemnis", "Ludwig Beethoven","03102019",["mp3", "song"], "https://URL Here")
]


function listSoundFiles()
  return InfoncastSoundFiles
end

function updateSoundFiles(InfoncastSoundFiles, title1, author, date1, tag1, url1)
    a = SoundFile(title1,author,date1,tag1,url1);
    #push!(InfoncastSoundFiles, a);
    append!(InfoncastSoundFiles, a);
    #print(InfoncastSoundFiles);
end


process(
    JuliaWebAPI.create_responder([
        (listSoundFiles, true),
        (updateSoundFiles, false)
    ], "tcp://127.0.0.1:9999", true, "")
)

httpsrvr.jl looks like this:

using JuliaWebAPI   #Load package

#Create the ZMQ client that talks to the ZMQ listener above
const apiclnt = APIInvoker("tcp://127.0.0.1:9999");

#Starts the HTTP server in current process
run_http(apiclnt, 8888)

As you can see, there's really not much that's different from the original example. Unfortunately, my lack of experience reading Julia code didn't allow me to decipher the options for JuliaWebAPI.create_responder to be able to configure it properly, which I think is the problem.

I would very much appreciate any help on this. As a matter of fact, I'll make a pull request to add it as one of the examples in the repo if you think it's worthwhile.

Thanks again.

Don't pay any attention to this. I asked on the Discord forum and got an answer. My function signature had errors In it.

It should look like this:

function updateSoundFiles( ; title1=title1, author1=author1, date1=date1, tag1=tag1, url1=url1)
	push!(InfoncastSoundFiles,SoundFile(title1,author1,date1,[tag1],url1))
end

and for some reason testing this via curl results in issues, but with a properly formatted URL it works.

http://localhost:8888/updateSoundFiles?title1=Concerto&author1=Beethoven&date1=01102020&tag1=classical&url1=https://duckduckgo.com

I'm still on the hook for adding this as an example if you'd like for others to learn from, perhaps noobs like me ;)

Thanks

Good to know that you were able to find a solution. I shall close this issue.

The README.md already has an example illustrating the use of keyword arguments. The only difference I see is your usage has only keyword arguments and no positional arguments. Is that what you want to add an example of? Please feel free to send in a PR with more examples!
