@Finesse

same problem in IOS WeChat

Finesse · 2021-04-27T01:45:06Z

@FeSeason @yuhonyon @caohongtao I need your help. Please scan this QR with WeChat so that I can sign up and debug the issue:

What the WeChat application says

Contact a WeChat user who meets the following conditions.(They do not have to be your WeChat friend.)

a. Signed up for WeChat over 1 month ago if they are an international user or over 6 months ago if they are a Chinese Mainland user
b. Hasn't completed "Help Friend Register" for other users in the past month
c. Hasn't been blocked in the past month
d. Has activated WeChat Pay if they are a Chinese Mainland user

Ask them to scan the following QR code using WeChat.

Finesse · 2021-04-28T03:00:30Z

Please give me access to WeChat or investigate the problem by yourself, otherwise I don't be able to help you. Please try to use NPM installation method and let me know if it helps.

Perpherior · 2021-04-28T04:38:24Z

Hi @Finesse, tried to scan the code but it says QR code is expired. Could you share a new one?

Finesse · 2021-04-28T04:52:26Z

@Perpherior @FeSeason Lets try registration first. Please try this code:

If I can’t register, then we will try to debug remotely.

Finesse · 2021-04-28T04:56:17Z

@FeSeason Thank you! I’ll check the bug soon

Finesse · 2021-04-28T06:42:03Z

I've found the reason of the bug. The fontPreferences entropy source doesn't complete. It creates an iframe with an srcdoc attribute and waits for the iframe to load, but the iframe doesn't load in WeChat browser for some reason.

I've found a solution. If I move the iframe.srcdoc = initialHtml line below the document.body.appendChild(iframe) line, the iframe starts getting loaded and get() returns a result. I'll publish a fix soon.

Finesse · 2021-04-28T08:14:41Z

The fix will be published in v3.1.1

zerrol · 2021-05-11T13:37:00Z

This problem was fixed in ios 14.x，but the problem still exisits in wechat with ios 13.x.
Please using wechat with ios 13.x . See this url: https://dev.hunliji.com/p/frontend/fingerprint-test/index.html.

…n iOS 13 (#645)

Finesse · 2021-05-12T02:36:39Z

Considering iOS 13. The fontPreferences and the fonts entropy sources don't complete. They create iframes and wait for the iframes to load, but the iframes don't load in WeChat browser for some reason. I've tried using both src and srcdoc, have tried changing the command order, nothing helps. Setting a real URL to the iframe src attribute helps, but making network requests isn't an option.

The solution that I've found is waiting until iframe.contentWindow.document.readyState becomes 'complete' (besides waiting for onload to fire). It fixes the problem in WeChat, keeps the correct iframe environment in Android Firefox and makes the source run faster in other browsers.

@zerrol Fixed by e11ed73. The fixed will be published in the next library release. If you need the fix soon, you can use the current master version: fp.min.js.zip.

Finesse · 2021-05-12T05:14:24Z

The problem happened in a Cordova application too (it uses WKWebView). The findings above are suitable for Cordova.

Finesse · 2021-06-01T07:31:08Z

The problem still happens in iOS 12.

@jyxu1016 Unfortunately, I don't have an iOS 12 device to debug, so you need to debug the issue by yourself. A probable reason is that an iframe loading promise never settles, therefore the withIframe function and the fonts and fontPreferences components never complete. You can check whether it's true on your device and try to find a way to know when the iframe is loaded to resolve the promise.

You can start your own FingerprintJS development playground to debug the issue: download the repository's code and follow the instructions. Once you start a playground and open it in WeChat, add alert()s to the source code to see what's going on.

I'll try to research the bug in a Cordova application on iOS 12 simulator, but it won't be a 100% reliable solution.

jyxu1016 · 2021-06-01T08:20:08Z

the problem also exisits in wechat with ios 13.x， read the comments above, this problem has always existed， IOS wechat is not available

Finesse · 2021-06-01T08:28:38Z

@jyxu1016 I can't reproduce it on iOS 13.6.1 WeChat 8.0.6. I open https://fingerprintjs.github.io/fingerprintjs and see this:

jyxu1016 · 2021-06-01T08:49:54Z

I open https://fingerprintjs.github.io/fingerprintjs/ ，I can get it, too

But using the following is not executed

fpPromise
.then((fp) => {
// Here can get fp
alert('hello 1')
return fp.get()
})
.then((result) => {
// ----------》No executed!! 《-------------
const visitorId = result.visitorId;
alert(visitorId);
});

Finesse · 2021-06-01T09:31:39Z

@jyxu1016 I've realized that the fix for iOS 13 hasn't been published yet, sorry. If you need the fix now, you can use the current master version: fp.min.js.zip. Please subscribe to the repository updates to get notified when the fix is published to NPM.

Could you please check whether https://fingerprintjs.github.io/fingerprintjs/ works in WeChat on iOS 12?

jyxu1016 · 2021-06-01T09:42:35Z

https://fingerprintjs.github.io/fingerprintjs/：it is available in WeChat on iOS 12
hope to published as soon as possible, thank

Finesse · 2021-06-01T09:51:19Z

@jyxu1016 Thank you. I think we will publish it soon.

jyxu1016 · 2021-06-11T14:01:37Z

@Finesse I'm waiting for you to publish every day

Finesse · 2021-06-14T09:58:34Z

@jyxu1016 The fix has just been released in v3.1.3
