一般情况下，Glide都是能正常访问Https图片的，因为日常的都是权威的CA证书，手机会自带这些证书，就认证过了，但是如果服务器用的是自签证书，这个时候就无法访问了，会报如下错误

javax.net.ssl.SSLHandshakeException(java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.)

接下来我们看看如何解决这个问题:

创建一个能忽略https的OkhttpClient,
替换Glide的加载器

创建一个能忽略https的OkhttpClient

这个网上有很多，我这简单贴下我的代码

object UnsafeOkHttpClient {
    /**
     * 创建一个忽略SSL校验的OkHttpClient
     * @param hostArray  你要忽略的域名，空数组 信任所有域名
      */  
    fun getUnsafeOkHttpClientByUrl( hostArray:Array<String>): OkHttpClient {
        try {
            Log.d("TAG", "忽略 getUnsafeOkHttpClient: ")
            // Create a trust manager that does not validate certificate chains
            val trustAllCerts = arrayOf<TrustManager>(TrustAllCertsTrustManager())

            // Install the all-trusting trust manager
            val sslContext = SSLContext.getInstance("SSL")
            sslContext.init(null, trustAllCerts, SecureRandom())
            // Create an ssl socket factory with our all-trusting manager
            val sslSocketFactory = sslContext.socketFactory

            val builder = OkHttpClient.Builder()
            builder.sslSocketFactory(
                sslSocketFactory,
                (trustAllCerts[0] as X509TrustManager)
            )

            builder.hostnameVerifier(CustomHostnameVerifier(hostArray))

            val okHttpClient = builder.build()
            return okHttpClient
        } catch (e: NoSuchAlgorithmException) {
            throw IllegalStateException(e)
        } catch (e: KeyManagementException) {
            throw IllegalStateException(e)
        }
    }
}
class CustomHostnameVerifier(private val allowedHost: Array<String>) : HostnameVerifier {
    override fun verify(hostname: String, session: SSLSession): Boolean {
        if (allowedHost.isEmpty()) {
            //空数组，则完全不拦截
            return true
        }
        for (host in allowedHost) {
            Log.d("TAG", " https verify:${host}    $hostname ")
            if (host.contains(hostname)) {

                return true
            }
        }


        return false
    }
}

替换Glide的加载器

在我们的AppLication中加入以下代码

Glide.get(this).registry.replace(
    GlideUrl::class.java,
    InputStream::class.java, OkHttpUrlLoader.Factory(UnsafeOkHttpClient.getUnsafeOkHttpClientByUrl(arrayOf()))
)

到这就结束了，很简单
