【问题描述】：
我有一个自签名服务器硬编码端口 52428。即使我覆盖 HostNameVerifier 以始终返回 true，我的客户端应用程序也会不断收到“主机名未验证”。当我将主机名从 IP 地址更改为 DNS 时，弹出另一个错误，显示“无法解析主机：没有与主机名关联的地址”
这是我的代码：
private class SSLConnect extends AsyncTask<Void, Void, String> {
@Override
protected String doInBackground(Void... values) {
//String https_url = "https://www.google.com/";
//String https_url = "https://192.168.0.106:52428/webserveradmin/preferences";
String https_url = "https://home-pc:52428/webserveradmin/preferences/";
String response;
try {
TrustManager[] tm = new TrustManager[]{
new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
//return new X509Certificate[0];
return null;
}
}
};
URL url;
try {
url = new URL(https_url);
}
catch (MalformedURLException e) {
return "Error URL: " + e.getMessage();
}
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
try {
conn.setDefaultHostnameVerifier(new NullHostNameVerifier());
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, tm, new SecureRandom());
conn.setSSLSocketFactory(sc.getSocketFactory());
conn.setRequestMethod("GET");
conn.setRequestProperty("Authorization", "Basic " + Base64.encode("sa:sa".getBytes(), Base64.DEFAULT));
conn.connect();
InputStream in = conn.getInputStream();
BufferedReader r = new BufferedReader(new InputStreamReader(in));
StringBuilder sb = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
sb.append(line);
}
response = sb.toString();
} catch (GeneralSecurityException e) {
return "Error Security: " + e.getMessage();
}
}
catch(Exception e){
return "Error SSL: " + e.getMessage();
}
return response;
}
@Override
protected void onProgressUpdate(Void... values) {
}
@Override
protected void onPostExecute(String result) {
Toast.makeText(ctxt, result, Toast.LENGTH_LONG).show();
}
}
public class NullHostNameVerifier implements HostnameVerifier{
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
}
【问题讨论】：
-
您明白请求URL域必须与证书的通用名称匹配吗？
-
@Simon 你能解释一下吗？抱歉，我对所有这些还是很陌生。
-
您是否为您的问题找到了合适的解决方案？我现在面临类似的问题

查看 Steffen 使用 Key Pinning 的解决方案。这解决了我的问题。
