Bad Request Handling

[ueliwechsler]

How would I implement a 400 bad request error handling in Bukdu?
Should I overwrite the Bukdu.System.internal_error method or is there a better way.
Thanks.

at first, see HTTP.jl's implementation.

• https://github.com/JuliaWeb/HTTP.jl/blob/master/src/Servers.jl#L351
• https://github.com/JuliaWeb/HTTP.jl/blob/master/test/server.jl

do you have any other case?

using Bukdu
using Test
using Sockets

port = 8080
Bukdu.start(port)

# from https://github.com/JuliaWeb/HTTP.jl/blob/master/test/server.jl

# invalid HTTP
tcp = Sockets.connect(ip"127.0.0.1", port)
write(tcp, "GET / HTP/1.1\r\n\r\n")
sleep(0.1)
@test occursin(r"HTTP/1.1 400 Bad Request", String(readavailable(tcp)))

# no URL
tcp = Sockets.connect(ip"127.0.0.1", port)
write(tcp, "SOMEMETHOD HTTP/1.1\r\nContent-Length: 0\r\n\r\n")
sleep(0.1)
r = String(readavailable(tcp))
@test occursin(r"HTTP/1.1 400 Bad Request", r)

Bukdu.stop()

Thanks for your detailed response.

I am not sure, but I think my case is not covered.
In my application, I receive a lot of huge JSONs via Post request. I would like to check the content of the request if it contains the correct keys and return a Bad Request Message if the keys does not exist.

[wookay]

then you could set the response.status. make a function or plug.

function check_the_content(c::YourController)
    # if the keys does not exist
    c.conn.request.response.status = 400
end

Thank you, this works for me.
