使用MATLAB的urlread命令处理无效的安全证书

考虑下面的Java类。我将此页面用作参考：

在HTTPS连接中禁用证书验证

C： MATLAB MyJavaClasses com stackoverflow Downloader.java

package com.stackoverflow;import java.io.BufferedReader;import java.io.InputStream;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.URL;import java.security.cert.X509Certificate;import javax.net.ssl.HttpsURLConnection;import javax.net.ssl.SSLContext;import javax.net.ssl.SSLSession;import javax.net.ssl.TrustManager;import javax.net.ssl.X509TrustManager;import javax.net.ssl.HostnameVerifier;public class Downloader {    public static String getData(String address) throws Exception {        // Create a trust manager that does not validate certificate chains        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {     public java.security.cert.X509Certificate[] getAcceptedIssuers() {         return null;     }     public void checkClientTrusted(X509Certificate[] certs, String authType) {     }     public void checkServerTrusted(X509Certificate[] certs, String authType) {     } }        };        // Create a host name verifier that always passes        HostnameVerifier allHostsValid = new HostnameVerifier() { public boolean verify(String hostname, SSLSession session) {     return true; }        };        // Install the all-trusting trust manager        SSLContext sc = SSLContext.getInstance("SSL");        sc.init(null, trustAllCerts, new java.security.SecureRandom());        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());        // Install the all-trusting host verifier        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);        // open connection        URL page = new URL(address);        HttpURLConnection conn = (HttpURLConnection) page.openConnection();        BufferedReader buff = new BufferedReader(new InputStreamReader(conn.getInputStream()));        // read text        String line;        StringBuffer text = new StringBuffer();        while ( (line = buff.readLine()) != null ) { //System.out.println(line); text.append(line + "n");        }        buff.close();        return text.toString();    }    public static void main(String[] argv) throws Exception {        String str = getData("https://expired.badssl.com/");        System.out.println(str);    }}

的MATLAB

首先，我们编译Java类（必须使用与MATLAB兼容的JDK版本）：

>> version -java>> system('javac C:MATLABMyJavaClassescomstackoverflowDownloader.java');

接下来，我们实例化并使用它作为MATLAB：

javaaddpath('C:MATLABMyJavaClasses')dl = com.stackoverflow.Downloader;str = char(dl.getData('https://expired.badssl.com/'));web(['text://' str], '-new')

以下是一些带有错误SSL证书的URL来进行测试：

urls = {    'https://expired.badssl.com/'       % expired    'https://wrong.host.badssl.com/'    % wrong host    'https://self-signed.badssl.com/'   % self-signed    'https://revoked.grc.com/'          % revoked};

更新：
我应该提到，从R2014b开始，MATLAB具有一个
