Intercepting mobile SDK network requests

Have greater control over networking requests made by the mobile SDKs.

iOS

You can provide the URLSession that will be used for all network requests made by the Cobrowse SDK.

CobrowseIO.instance().urlSession = \\ Your URLSession object

By setting a delegate on the provided URLSession object it will be told of any network request. You can then take action such as cancelling the task to block the network request from being made.

class CustomURLSessionDelegate: NSObject, URLSessionTaskDelegate {
    
    func urlSession(_ session: URLSession, didCreateTask task: URLSessionTask) {
        let allowedHosts = ["api.cobrowse.io"]
        
        guard let host = task.currentRequest?.url?.host, !allowedHosts.contains(host)
            else { return }
        
        print("Blocking data task for host: \(host)")
        task.cancel()
    }
}

Requires iOS 15+ macOS 12+

Android

Cobrowse SDK uses OkHttp for network communication. You can provide an OkHttpClient instance that will be used for all HTTP requests made by the Cobrowse SDK.

CobrowseIO.instance().okHttpClient(
    OkHttpClient.Builder()
        .addInterceptor(LoggingInterceptor())
        .build()
)

By setting an interceptor on the provided OkHttpClient object it will be told of any network request. You can then take action such as throwing an exception to block the network request from being made.

class LoggingInterceptor : Interceptor {
    companion object {
        private val allowedHosts = setOf(".cobrowse.io")
    }

    override fun intercept(chain: Interceptor.Chain): Response {
        val request = chain.request()
        val host = request.url().host()
        if (allowedHosts.any { host.endsWith(it) }) {
            return chain.proceed(request)
        } else {
            throw IOException("This request is not allowed: " + request.url())
        }
    }
}
