Web scrape and validation

General
1

Hi all !.

A few months back i was working on a project were i scrap some part of this web site: Tasmota ESP8266 Binaries specially on the "version" element.
Then, I validate the Tasmota version via http API and finally i compare the web version and the tasmota version to finally decide if the tasmota device is updated or not.

This is the actual flow i'm using with harcoded Tasmota information so it can be reproduced.

Problems:

  1. suddenly the web scrap stopped working. It cannot retrieve the td or tr element. Maybe changed on the website or something is missing.
  2. The tasmota version is not working too. No information comes along.

I've been opening this issues some months ago.

Any help will be grateful!.

Regards,

Martin.-

I imported your flow and it seems to be working for me. Is there something else this should be doing?

I doubt it just stopped working - my guess is you have updated node-red (or are running this flow on a newer version of node-red) as it does indeed NOT work on newer node-red. What version of node-red is this?

@mdkrieg my guess is you are running node-red V1.x?

@Marty1982 the workaround is to wrap the td with td and table

function code...

msg.payload = `<table><tr>${msg.payload}</tr></table>`
return msg;

Uhm ok...i use version 2.0.6 and maybe something is failing on that version.
So, if i add that wrap id now i get this:

Somehow i'm getting the Current / Old values empty....

You wont get anything in "current" if you dont use real data. Remember this...

the picture (and flow) you posted uses fake data - and that fake data has 2 entries, both with version older than "10.0.0"

so if you ...

  • expand the current (as in array of devices with current firmware) it is empty.
  • expand the old (as in array of devices with old firmware) it has 2 entries.

image

in simple terms - it does work.

Did you put the code in the function exactly as I wrote it?

Here is my copy (of your copy of my old flow) - it works for me on V2.x of node-red ...

EDIT

Did you operate both inject buttons?

Ok.... thanks for the answer!

No i have this error.

I've modified the function "hosts" where it hold the real host ip but the http cannot be complete.

Regards!

Has this ever worked?

The hosts function sent an msg with msg.complete (empty url) to trigger the join node to release the data.

The error you are seeing is because msg.url is not set for that last message.

So I modified the hosts function to set msg.complete on the last host msg (instead of sending an extra msg with empty url)

try this...

Ok...now this is what i have replacing the http request node.

Before it worked fine, very strange it stopped working suddenly.

Thanks again!

Did you update the host IP addresses in the host function node?

put debug nodes (set to show complete message) after EVERY node and see what is happening & where it breaks down.

10

Ok this are the debugs. I've already updated the hosts ip in function node before. In fact i have only one host now 192.168.1.4

Yes, but as i explained before...

Did you use the new hosts function code I provided?

show me whats in your hosts function.

12

This is my host node with the information i have right now.

13

set the HTP Request like this...

14

OK, done!.

Now at the end of the flow i have an empty data.
But previously i can get both information, webversion and device version.
So maybe there is something wrong in the final function.

deviceData is an array in the code I sent you - you have an object.

image
image1002×668 43.1 KB

It looks like this is due to there only being 1 item in your hosts function. The join is outputing the single object instead of an array of 1 item - a new curve ball for me! I thought it would still output an array!

No matter, we can work around this.

Edit the last function node to this...

var webVersion = msg.payload.availableVersion; //get web version
var deviceData = msg.payload.deviceData; //get array of devices

if (Array.isArray(deviceData) == false) {
    deviceData = [deviceData];
}

var current = [];//where results will go
var old = [];
//loop through each device
for (let i = 0; i < deviceData.length; i++) {
    let device = deviceData[i]; //get this device
    var v = device.version; //get device version
    device.version = v.split("(")[0]; //split on "(" then take first element [0]
    device.webVersion = webVersion; //optional
    device.match = (device.version == device.webVersion); //compare device version to webVersion
    if(device.match) {
        current.push(device); //add result
    } else {
        old.push(device); //add result
    }
}

msg.payload = {
    current: current,
    old: old
}
return msg;
16

Curve ball! jajaja, because of this projects with trial and fail comes the curved ball.

Now it seems to brings the right data!.
