使用 HttpsURLConnection 忽略 ssl 证书的方法

Question

我使用两种方法来尝试使用 HTTPS URL：

旧的已弃用并返回正确值的响应。

这是它不需要忽略 ssl 证书的代码，它会自行忽略它或可能使用其他技术：

  public String newApiPost(String url,String p1,String p2,String p3){

    HttpClient httpClient = new DefaultHttpClient();
    // replace with your url
    HttpPost httpPost = new HttpPost(url);

    //Post Data
    List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>
    ();
    nameValuePair.add(new BasicNameValuePair("cliend_id",p1));
    nameValuePair.add(new BasicNameValuePair("client_secret", p2));
    nameValuePair.add(new BasicNameValuePair("key",p3));


    //Encoding POST data
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
     } catch (UnsupportedEncodingException e) {
        // log exception
        e.printStackTrace();
    }

    //making POST request.
    try {
        HttpResponse response = httpClient.execute(httpPost);
        HttpEntity httpEntity = response.getEntity();
          String   result = EntityUtils.toString(httpEntity,     
      HTTP.UTF_8);
       Log.d("response", result);

        // write response to log
        Log.d("zzuu", result.toString());
    } catch (ClientProtocolException e) {
        // Log exception
        e.printStackTrace();
    } catch (IOException e) {
        // Log exception
        e.printStackTrace();
        Log.d("dddfg", e.toString());

    }catch (Exception e){
        Log.d("dddfg", e.toString());

    }

    return "";
 }

然后我使用了不推荐使用的方法 HttpsUrlConnections 需要忽略 ssl 证书我使用了很多方法但没有工作：

   public void sendNew (String urls,String paramValue1,String   
        paramValue2,String paramValue3){
    URL url = null;
    BufferedReader reader = null;
    StringBuilder stringBuilder;
    String data="";

    try {
        url = new URL(urls);
     HttpsURLConnection conn = (HttpsURLConnection)  
     url.openConnection();

         conn.setReadTimeout(10000);
    conn.setConnectTimeout(15000);
        conn.setRequestMethod("POST");
    conn.setRequestProperty("Content-Type", "application/x-www-form- 
     urlencoded");
    conn.setRequestProperty("charset", "utf-8");
    conn.setDoInput(true);
       conn.setDoOutput(true);
    Uri.Builder builder = new Uri.Builder()
            .appendQueryParameter("cliend_id", paramValue1)
            .appendQueryParameter("client_secret", paramValue2)
            .appendQueryParameter("apikey", paramValue3);
    String query = builder.build().getEncodedQuery();

    OutputStream os = conn.getOutputStream();
    BufferedWriter writer = new BufferedWriter(
            new OutputStreamWriter(os, "UTF-8"));
    writer.write(query);
    writer.flush();
    writer.close();
    os.close();

    conn.connect();

         reader = new BufferedReader(new   
         InputStreamReader(conn.getErrorStream()));
        stringBuilder = new StringBuilder();

        String line = null;
        while ((line = reader.readLine()) != null)
        {
            stringBuilder.append(line + "\n");

        }
        data= stringBuilder.toString();
        Log.d("zzuu", data);

    } catch (MalformedURLException e) {
    e.printStackTrace();
   } catch (ProtocolException e) {
        e.printStackTrace();
        Log.d("dddfg", e.toString());

    } catch (IOException e) {
        e.printStackTrace();
        Log.d("dddfg", e.toString());

    }catch (Exception e){
        Log.d("dddfg", e.toString());

    }
}

它以这个错误响应：

我不明白什么时候问题在 restclient 和 postman 中运行良好 使用 post 方法在 url 正文中发送数据 然后我发现在使用 HttpsURLConnection 时我需要忽略 ssl 证书，但我尝试了很多方法来忽略但没有用

   I use 

       private void trustEveryone() {
       try {
         HttpsURLConnection.setDefaultHostnameVerifier(new 
        HostnameVerifier(){
            public boolean verify(String hostname, SSLSession session) 
     {
                 return true;
              }});
           SSLContext context = SSLContext.getInstance("TLS");
          context.init(null, new X509TrustManager[]{new 
        X509TrustManager(){
            public void checkClientTrusted(X509Certificate[] chain,
                                           String authType) throws 
                 CertificateException {}
            public void checkServerTrusted(X509Certificate[] chain,
                                           String authType) throws 
          CertificateException {}
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }}}, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(
                context.getSocketFactory());
      } catch (Exception e) { // should never happen
        e.printStackTrace();
      }
   }

Answer 1

从您的 logcat 信息来看，我认为您应该阅读以下链接：

1. HostnameVerifier

   如果 URL 的主机名与对等方的标识主机名不匹配，则在握手期间使用它。

2. Common Problems with Hostname Verification

   发生这种情况的一个原因是服务器配置错误。这 服务器配置了没有主题的证书 或与您所在的服务器匹配的主题备用名称字段 试图到达...

那么，你可以参考我对以下问题的回答：

编辑：关于你的想法'ignore ssl'，你可以尝试以下（但是据说不推荐这样做）：

public class HttpsTrustManager implements X509TrustManager {
    private static TrustManager[] trustManagers;
    private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};

    @Override
    public void checkClientTrusted(
            X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {

    }

    @Override
    public void checkServerTrusted(
            X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {

    }

    public boolean isClientTrusted(X509Certificate[] chain) {
        return true;
    }

    public boolean isServerTrusted(X509Certificate[] chain) {
        return true;
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return _AcceptedIssuers;
    }

    public static void allowAllSSL() {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {

            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                return true;
            }

        });

        SSLContext context = null;
        if (trustManagers == null) {
            trustManagers = new TrustManager[]{new HttpsTrustManager()};
        }

        try {
            context = SSLContext.getInstance("TLS");
            context.init(null, trustManagers, new SecureRandom());
        } catch (NoSuchAlgorithmException | KeyManagementException e) {
            e.printStackTrace();
        }

        HttpsURLConnection.setDefaultSSLSocketFactory(context != null ? context.getSocketFactory() : null);
    }
}

然后，在您的活动中，致电HttpsTrustManager.allowAllSSL();
