Accessing web with HTTP auth

[janpeterka]

Hi, I'm trying to create Android app for the first time. I'm struggling with using it with web that is behind HTTPAuth (test server).

I tried creating custom WebView, as described here, and calling setHttpAuthUsernamePassword (which is deprecated, but I just wanted to make first working version).
It might be just because I have no prior experience with Kotlin and Android development, but I cannot get it to work.

I would appreciate any help for that.
Also, if there's a standard way to solve this, it might be worth adding to Hotwire Native resources or even add as configurable property of HotwireWebView.

Thanks for any help!

In my code I see something like this

open class KinoTurboWebFragment : HotwireWebFragment(), NavDestination {

    companion object {
        var user: String? = null
        var password: String? = null
    }

    override fun onReceivedHttpAuthRequest(handler: HttpAuthHandler, host: String, realm: String) {
        handler.proceed(user, password)
    }
}

I think this does the magic.

Yes, Hotwire.registerFragmentDestinations is also required.

[janpeterka]

I also found Hotwire.defaultFragmentDestination in demo, maybe that's enough?

[janpeterka]

Can you please post the whole file with your KinoTurboWebFragment?

[janpeterka]

Also, what version of HotwireNative do you use?

Thank you so much!

Ok, I got to working solution, thanks for you pointing me in correct direction!

Thanks to @MichalSznajder, code of demo application and the Hotwire native for Rails developers book , I managed to create a working code:

1. I had to create MyApplication.kt file with following code:

package com.myaap

import android.app.Application
import dev.hotwire.core.config.Hotwire
import dev.hotwire.navigation.config.defaultFragmentDestination
import dev.hotwire.navigation.config.registerFragmentDestinations

class MyApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        configureApp()
    }

    private fun configureApp(){
        // CustomWebFragment manages HTTPAuth connection to sandbox
        Hotwire.defaultFragmentDestination = CustomWebFragment::class
        Hotwire.registerFragmentDestinations(CustomWebFragment::class)
    }
} 

2. Then added this application to AndroidManifest.xml:

    <application
        android:name=".MyApplication"
        ...

3. Then I created CustomWebFrament.kt file with this code:

package com.myapp

import android.webkit.HttpAuthHandler
import dev.hotwire.navigation.destinations.HotwireDestinationDeepLink
import dev.hotwire.navigation.fragments.HotwireWebFragment

@HotwireDestinationDeepLink(uri = "hotwire://fragment/web")
open class CustomWebFragment : HotwireWebFragment() {
    override fun onReceivedHttpAuthRequest(handler: HttpAuthHandler, host: String, realm: String) {
        handler.proceed("ourusername", "oursecretpasswork")
    }
}

And now I am sucessfully getting through HTTPAuth.

It's advisable not to have username and password hardcoded, but I don't know yet how to do that.

@MichalSznajder didn't you by chance also did solve this for iOS? 😁

You need some research but starting point is:

extension TabBarViewController: NavigatorDelegate {
    func didReceiveAuthenticationChallenge(_ challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void)
    {
        let user = "secret_user"
        let pass = "secret_pass"
        
        let credential = URLCredential(user: user,
                                       password: pass,
                                       persistence: .permanent)
        completionHandler(.useCredential, credential)
}
'''

`TabBarViewController` is my custom view controller. Search for `NavigatorDelegate` and you will find view controller from your project.

I am still on `1.1.0` but head is same AFAIK.

Thank you so much, after some try-and-error I did manage to make this work!
