Hi help me API respone fetchRemote

[framef318]

I tried using the API instead of direct mysql connection but I ran into a problem where I couldn't retrieve the API response value. It said it was a string. I tried converting it using toJSON and fromJSON and it didn't work.

 

function hangetdleApiResponse(data, info)
    local json = toJSON(data)
    local result = fromJSON(data)
    if result then
        for _, user in ipairs(result) do //  ipairs(json)
            iprint("ID: " .. user.id)
            iprint("Username: " .. user.username)
            iprint("Email: " .. user.email)
        end
    else
        iprint("Error parsing JSON data")
    end
end


function getApiData()
    local url = 'http://127.0.0.1:8000/user/'
    sendOptions = {
        connectionAttempts = 3,
        connectTimeout = 5000,
        method = "GET",
        formFields = {},
    }
    fetchRemote(url, sendOptions, function(data, info)
        hangetdleApiResponse(data, info)
    end)
end

 

data repose json

[
    {
        "id": 49,
        "username": "framef318",
        "email": "[email protected]"
    },
    {
        "id": 50,
        "username": "framef3188",
        "email": "[email protected]"
    }
]

And if you do:

local result = {fromJSON(data)}

?

 

    {
        "id": 49,
        "username": "framef318",
        "email": "[email protected]"
    },

This is one return value.

local a, b = fromJSON(data)

 

    {
        "id": 50,
        "username": "framef3188",
        "email": "[email protected]"
    }

And this is one return value.

local a, b = fromJSON(data)

 

Other way (untested):

local result = fromJSON("[" .. data .. "]")

Thank you very much. I'll try it out.

local a, b = fromJSON(data)

If I can't know how many values to return, what do I do with local a, b?

This function can return one table, which also contains other tables, so you don't need to declare multiple variables to store the return vale of it.

I still don't understand, does that mean I can use for in and fromJSON(data)? But it seems like I've done this before and it didn't produce any results.

That is why you can capture those by surrounding the fromJSON with a table:

local result = {fromJSON(data)}

 

Although this solution might be more optimised:

local result = fromJSON("[" .. data .. "]")

It changes your data string to:

[[
    {
        "id": 49,
        "username": "framef318",
        "email": "[email protected]"
    },
    {
        "id": 50,
        "username": "framef3188",
        "email": "[email protected]"
    }
]]

Which helps returning everything inside of 1 variable, instead of multiple.
