使用 HTTPS 的 HttpGet：SSLPeerUnverifiedException

Question

使用 HttpClient，尝试通过 HTTPS 进行通信时收到以下错误：

线程“main”中出现异常 javax.net.ssl.SSLPeerUnverifiedException：对等点未经过身份验证。

这是我的代码：

URI loginUri = new URI("https://myUrl.asp");

HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet( loginUri );
HttpResponse response = httpclient.execute( httpget );

如何抑制或删除此错误？

Answer 1

注意：不要在生产代码中执行此操作，而是使用 http 或上面建议的实际自签名公钥。

在 HttpClient 4.xx 上：

import static org.junit.Assert.assertEquals;

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
import org.junit.Test;

public class HttpClientTrustingAllCertsTest {

    @Test
    public void shouldAcceptUnsafeCerts() throws Exception {
        DefaultHttpClient httpclient = httpClientTrustingAllSSLCerts();
        HttpGet httpGet = new HttpGet("https://host_with_self_signed_cert");
        HttpResponse response = httpclient.execute( httpGet );
        assertEquals("HTTP/1.1 200 OK", response.getStatusLine().toString());
    }

    private DefaultHttpClient httpClientTrustingAllSSLCerts() throws NoSuchAlgorithmException, KeyManagementException {
        DefaultHttpClient httpclient = new DefaultHttpClient();

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, getTrustingManager(), new java.security.SecureRandom());

        SSLSocketFactory socketFactory = new SSLSocketFactory(sc);
        Scheme sch = new Scheme("https", 443, socketFactory);
        httpclient.getConnectionManager().getSchemeRegistry().register(sch);
        return httpclient;
    }

    private TrustManager[] getTrustingManager() {
        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }

            @Override
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
                // Do nothing
            }

            @Override
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
                // Do nothing
            }

        } };
        return trustAllCerts;
    }
}

Answer 2

这个答案遵循 owlstead 和 Mat 的回应。它适用于 SE/EE 安装，不适用于 ME/移动/Android SSL。

由于还没有人提到它，我将提及解决此问题的“生产方式”：
按照 HttpClient 中的 AuthSSLProtocolSocketFactory 类 来更新您的信任存储 &关键商店。

1. 导入可信证书并生成信任库文件

keytool -import -alias "my server cert" -file server.crt -keystore my.truststore

2. 生成新密钥（使用与信任库相同的密码）

< code>keytool -genkey -v -alias "my client key" -validity 365 -keystore my.keystore

3. 发出证书签名请求 (CSR)

keytool -certreq -alias "my client key" -file mycertreq .csr -keystore my.keystore

4. （自签名或让您的证书签名）

5. 导入受信任的 CA 根证书

keytool -import -alias "my Trusted ca" -file caroot.crt -keystore my.keystore

6. 导入包含完整证书链的 PKCS#7 文件

keytool - import -alias "my client key" -file mycert.p7 -keystore my.keystore

7. 验证生成的密钥库文件的内容

keytool -list -v -keystore my.keystore

如果不这样做拥有服务器证书，生成 JKS 格式的证书，然后将其导出为 CRT 文件。 来源：keytool 文档

keytool -genkey -alias server-alias -keyalg RSA -keypass changeit
    -storepass changeit -keystore my.keystore

keytool -export -alias server-alias -storepass changeit
    -file server.crt -keystore my.keystore

Answer 3

使用 HttpClient 3.x，您需要执行以下操作：

Protocol easyHttps = new Protocol("https", new EasySSLProtocolSocketFactory(), 443);
Protocol.registerProtocol("https", easyHttps);

EasySSLProtocolSocketFactory 的实现可以找到 此处。

Answer 4

如果您的服务器基于 JDK 7 并且您的客户端基于 JDK 6 并使用 SSL 证书，则会出现此异常。在 JDK 7 中，默认禁用 sslv2hello 消息握手，而在 JDK 6 中，启用 sslv2hello 消息握手。因此，当您的客户端尝试连接服务器时，将向服务器发送 sslv2hello 消息，并且由于 sslv2hello 消息禁用，您将收到此异常。要解决此问题，您必须将客户端移至 JDK 7，或者必须使用 6u91 版本的 JDK。但要获取此版本的 JDK，您必须获取

Answer 5

返回“secureClient”的方法（在 Java 7 环境中 - NetBeans IDE 和 GlassFish Server：端口 https 默认为 3920 ），希望这可以有所帮助：

public DefaultHttpClient secureClient() {
    DefaultHttpClient httpclient = new DefaultHttpClient();
    SSLSocketFactory sf;

    KeyStore trustStore;
    FileInputStream trustStream = null;
    File truststoreFile;
    // java.security.cert.PKIXParameters for the trustStore
    PKIXParameters pkixParamsTrust;

    KeyStore keyStore;
    FileInputStream keyStream = null;
    File keystoreFile;
    // java.security.cert.PKIXParameters for the keyStore
    PKIXParameters pkixParamsKey;

    try {
        trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        truststoreFile = new File(TRUSTSTORE_FILE);
        keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
        keystoreFile = new File(KEYSTORE_FILE);
        try {
            trustStream = new FileInputStream(truststoreFile);
            keyStream = new FileInputStream(keystoreFile);
        } catch (FileNotFoundException ex) {
            Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
        }
        try {
            trustStore.load(trustStream, PASSWORD.toCharArray());
            keyStore.load(keyStream, PASSWORD.toCharArray());
        } catch (IOException ex) {
            Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
        } catch (CertificateException ex) {
            Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
        }
        try {
            pkixParamsTrust = new PKIXParameters(trustStore);
            // accepts Server certificate generated with keytool and (auto) signed by SUN
            pkixParamsTrust.setPolicyQualifiersRejected(false);
        } catch (InvalidAlgorithmParameterException ex) {
            Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
        }
        try {
            pkixParamsKey = new PKIXParameters(keyStore);
            // accepts Client certificate generated with keytool and (auto) signed by SUN
            pkixParamsKey.setPolicyQualifiersRejected(false);
        } catch (InvalidAlgorithmParameterException ex) {
            Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
        }
        try {
            sf = new SSLSocketFactory(trustStore);
            ClientConnectionManager manager = httpclient.getConnectionManager();
            manager.getSchemeRegistry().register(new Scheme("https", 3920, sf));
        } catch (KeyManagementException ex) {
            Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
        } catch (UnrecoverableKeyException ex) {
            Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
        }

    } catch (NoSuchAlgorithmException ex) {
        Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
    } catch (KeyStoreException ex) {
        Logger.getLogger(ApacheHttpRestClient.class.getName()).log(Level.SEVERE, null, ex);
    }
    // use the httpclient for any httpRequest
    return httpclient;
}

您的本地 JVM 或远程服务器可能没有所需的密码。转到这里

https://www.oracle.com/java/technologies/ javase-jce8-downloads.html

并下载包含以下内容的 zip 文件：
US_export_policy.jar
和
local_policy.jar

替换现有文件（您需要在 JVM 中找到现有路径）。

在 Mac 上，我的路就在这里。
/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/security

这对我有用。
