MockWebserver Retrofit - SSLHandshakeException: connection closed-CodePudding

I am writing a UI test using Espresso, Dagger2, Retrofit, and MockWebserver for mocking API response. I follow this tutorial by Weidian Huang on medium -> full github source here. Iam not using SSL pinning so I remote it. But I got problem when trying to change webmockserver interceptor. The log show error line is here chain.proceed(request).

class DebugUrlInterceptor : Interceptor {
    override fun intercept(chain: Interceptor.Chain): Response {
        var request: Request = chain.request()
        if (MockServerManager.shouldMockApi(request.url.encodedPath)) {
            val newUrl: HttpUrl = request.url.newBuilder()
                .scheme(MockServerManager.HTTPS_SCHEME)
                .host(MockServerManager.HOST)
                .port(MockServerManager.port)
                .build()

            request = request.newBuilder()
                .url(newUrl)
                .headers(request.headers)
                .method(request.method, request.body)
                .build()
        }
        return chain.proceed(request)
    }
}

I did use x509Trustmanager but it's still not working.

    @Provides
    @Named("unsafe")
    fun provideUnSafeOkHttpClient(okHttpClientBuilder: OkHttpClient.Builder): OkHttpClient {
        val x509TrustManager = @SuppressLint("CustomX509TrustManager")
        object : X509TrustManager {
            @SuppressLint("TrustAllX509TrustManager")
            override fun checkClientTrusted(
                chain: Array<out X509Certificate>?,
                authType: String?
            ) {
            }

            @SuppressLint("TrustAllX509TrustManager")
            override fun checkServerTrusted(
                chain: Array<out X509Certificate>?,
                authType: String?
            ) {
            }

            override fun getAcceptedIssuers(): Array<X509Certificate> {
                return arrayOf()
            }
        }

        val trustManagers = arrayOf<TrustManager>(x509TrustManager)

        val sslContext = SSLContext.getInstance("SSL")
        sslContext.init(null, trustManagers, java.security.SecureRandom())

        okHttpClientBuilder.sslSocketFactory(sslContext.socketFactory, x509TrustManager)
        okHttpClientBuilder.hostnameVerifier { _, _ -> true }

        return okHttpClientBuilder.build()
    }

Do anyone done this before please help, I've spent a day for that :((

CodePudding user response：

The problem is here:

val newUrl: HttpUrl = request.url.newBuilder()
                .scheme(MockServerManager.HTTPS_SCHEME)
                .host(MockServerManager.HOST)
                .port(MockServerManager.port)
                .build()

It's need to be HTTP_SCHEME instead of HTTPS_SCHEME
