我有以下kotlin代码:
val urlPath = "https://10.0.2.2:8080"
var data: String
try {
data = URL(urlPath).readText()
} catch (e: Exception) {
Log.e("doInBackground", "Exception caught: ${e.localizedMessage}")
error = when (e) {
is MalformedURLException -> "Invalid URL"
is IOException -> "Network Error"
else -> {
"Network error: ${e.localizedMessage}"
}
}
}
如果我使用上面的代码连接到http服务器,上面的代码可以正常工作。但是,当我尝试使用自签名证书连接到https服务器时,它会失败。有没有办法在localhost上允许https连接(仅限),即使证书是自签名的?
答案 0 :(得分:3)
这是一个使用JSSE从https://google.com读取的示例,它完全信任每个证书,不应该有效地使用。
fun main(args: Array<String>) {
val urlPath = "https://google.com"
try {
(URL(urlPath).openConnection() as HttpsURLConnection).apply {
sslSocketFactory = createSocketFactory(listOf("TLSv1.2"))
hostnameVerifier = HostnameVerifier { _, _ -> true }
readTimeout = 5_000
}.inputStream.use {
it.copyTo(System.out)
}
} catch (e: Exception) {
TODO()
}
}
private fun createSocketFactory(protocols: List<String>) =
SSLContext.getInstance(protocols[0]).apply {
val trustAllCerts = arrayOf<TrustManager>(object : X509TrustManager {
override fun getAcceptedIssuers(): Array<X509Certificate> = arrayOf()
override fun checkClientTrusted(certs: Array<X509Certificate>, authType: String) = Unit
override fun checkServerTrusted(certs: Array<X509Certificate>, authType: String) = Unit
})
init(null, trustAllCerts, SecureRandom())
}.socketFactory
我为这些事情here设了一个小图书馆,既不是最新的也不是已发表的。然而,它提供了一个简单的DSL来设置TLS / SSL套接字,并为https连接提供了方法。
