Invalid backslash in uploaded json

[plerohellec]

I'm receiving invalid yabs.sh json payloads almost daily at vpsbenchmarks.com. They are invalid because one or more strings in the json include a backslash that is not used as an escape character. It looks like the \ is escaping a double quote but it was not meant to. For example:
"asn":"AS44486 Oliver Horscht is trading as \SYNLINQ\"
or
"isp":"OOO \Network of data-centers \Selectel\"

Would it be possible to escape or delete those backslashes before including them in the json strings?

Here is an example with the full json input:
yab.invalid-backslash.json

Appreciate the bug report! Should be easy to filter out the backslashes. Has the network details section been the only area you have been receiving backslashes? I don't think any other field would be susceptible to bad input, but I want to confirm before implementing a change.

Yes, I've only seen it in the isp and asn fields but I assume all of the ip_info section is susceptible of including those backslashes. I suppose the backslash could also be found in cpu models since VPS providers can set it any way they want.
Thanks for taking the time to fix this!

I just realized that ip-api.com returns json like this in those cases:

{
    "as": "AS44486 Oliver Horscht is trading as \"SYNLINQ\"",
    "city": "Frankfurt am Main",
    "country": "Germany",
    "countryCode": "DE",
    "isp": "Oliver Horscht is trading as \"SYNLINQ\"",
    "lat": 50.1109,
    "lon": 8.68213,
    "org": "Solutions Virfect",
    "query": "103.252.88.1",
    "region": "HE",
    "regionName": "Hesse",
    "status": "success",
    "timezone": "Europe/Berlin",
    "zip": "60313"
}

So yabs.sh must be removing the " but keeping the \. It should either keep them both (ip-api.com returns valid json after all, there might be no need to alter those strings) or remove them both

Just pushed some changes (52f048b) to fix this. Can you give it a test and let me know if it worked? Should leave any instances of \" intact.

[plerohellec]

I don't know how to test this particular case, I would need a server with an IP address tied to those special ip info strings, which I don't have. But I received a few yabs in the past 10 hours from random IPs, I ran one myself and the generated json is valid.
Thank you for the fix!

Right, makes sense. Well please let me know if this comes up again and we'll re-open this issue!

No problem, thanks for the bug report!
