Testing data recieved from http.request

Questions
1

I was wondering if I could test what is being displayed on the webpage? Such as, if a certain image is displayed on a website’s homepage

I think you can get the webpage, but I’m not sure how you would identify a specific image unless you knew the name of the images being displayed.

@dave1707 I have the names of the images, however I don’t know the code of how to learn which of the three it is using

Here’s some code that will show data received from a url, in this example, google.com . You can scroll the page up or down to show more text. I don’t know if this will be helpful or not.

displayMode(FULLSCREEN)

function setup()
    font("Courier")
    textMode(CORNER)
    setup1()
    dy=0
    da=0
    hda=0
    str=""
    
    url="http://www.google.com"
    
    http.request(url,response)
end

function setup1()
    rows=44
    char=75
    if WIDTH>768 then
        rows=32
        char=100
    end
end
    
function response(data,status,headers)
    print("response")
    str=data
    print(string.sub(str,1,170))
    dataLen=str:len()
    print("status",status)
    print("headers")
    for a,b in pairs(headers) do
        print(a,b)
    end
end

function draw()
    background(40, 40, 50)
    if hw~=WIDTH then
        setup1()
    end
    fill(255)
    if str~="" then
        pos=1
        startCount=pos+dy
        for z=1,rows do
            str1=""
            for z1=pos+dy,pos+dy+char-1 do
                if z1<=dataLen then
                    v=string.sub(str,z1,z1)
                    if string.byte(v)==10 then
                        v="€"
                    elseif string.byte(v)<32 or string.byte(v)>127 then
                        v="¿"
                    end
                    str1=str1..v
                    endCount=z1
                end
            end                   
            text(str1,0,HEIGHT-50-21*z)
            pos=pos+char
        end
        header=string.format("(Start %6d)     (End %6d)     (Size%6d)",startCount,endCount,dataLen)
        text(header,150,HEIGHT-20)
    else
        text("Reading or No Data",WIDTH/2,HEIGHT/2)
   end
end

function touched(t)
    da=da+t.deltaY/21
    if da<0 then
        da=0
    elseif da>(dataLen/char)-(rows-4) then
        da=hda
    end
    dy=math.floor(da)*char
    hda=da
end

@dave1707 , It’s going to sound stupid, but you could explain what that code is doing. I’m sorry I don’t understand, my brain is fried from trying to decipher how the programmers set up the website I am trying to test

@AnotherBoringUser There’s not a whole lot to explain. It does a request to the url and just displays the information coming back as text. That’s about the only thing it does. A new line character is replaced with € and any unprintable characters with ¿ .

@dave1707 Okay that was what was confusing me. I didn’t realize what it was doing
