我关注了 stackoverflow 上的许多链接并尝试了许多解决方案，但没有一个对我有用。我正在使用
WSO2 API manager1.9.1Exception in thread "main" javax.net.ssl.SSLPeerUnverifiedException: Host name 'XXXXXXXXX' does not match the certificate subject provided by the peer (CN=localhost, O=WSO2, L=Mountain View, ST=CA, C=US)

我开发了以下Java代码。请帮我看看这里出了什么问题。我需要以不安全的方式连接并允许在没有证书的情况下连接到 SSL 站点。
public static void main(String[] args) throws ClientProtocolException, IOException, NoSuchAlgorithmException, KeyStoreException, KeyManagementException {
SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build());
Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
.register("http", new PlainConnectionSocketFactory())
.register("https", sslsf)
.build();
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
cm.setMaxTotal(2000);//max connection
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf)
.setConnectionManager(cm).build();
HttpGet httpGet = new HttpGet("https://XXXXXXXXXX:8243/token");
CloseableHttpResponse response = httpclient.execute(httpGet);
String json =" {\"data\":\"grant_type=password&username=test&password=test123\"}";
try {
HttpPost httpost = new HttpPost(url);
httpost.setHeader("Content-Type", "application/x-www-form-urlencoded");
httpost.setHeader("Authorization", "Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
httpost.setEntity(new StringEntity(json));
HttpResponse httpResponse = httpclient.execute(httpost);
System.out.println(httpResponse.getStatusLine());
}
finally {
response.close();
}
String responseString1 = new BasicResponseHandler().handleResponse(response);
System.out.println("Response : "+responseString1);
}
我花了一个小时尝试解决同样的问题。这就是我想到的：
final SSLConnectionSocketFactory sslsf;
try {
sslsf = new SSLConnectionSocketFactory(SSLContext.getDefault(),
NoopHostnameVerifier.INSTANCE);
} catch (NoSuchAlgorithmException e) {
throw new RuntimeException(e);
}
final Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
.register("http", new PlainConnectionSocketFactory())
.register("https", sslsf)
.build();
final PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
cm.setMaxTotal(100);
httpClient = HttpClients.custom()
.setSSLSocketFactory(sslsf)
.setConnectionManager(cm)
.build();
希望它能够正常工作并且不使用任何已弃用的代码（httpclient 4.4.1）。
更换这个
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf)
.setConnectionManager(cm).build();
与
CloseableHttpClient httpclient = HttpClients.custom()
.setSSLSocketFactory(sslsf)
.setConnectionManager(cm)
.setHostnameVerifier(SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)
.build();
如果证书未签名（甚至不是自签名），那么你可以这样做
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
public class TrustAllStrategy implements TrustStrategy {
@Override
public boolean isTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
return true;
}
}
然后
builder.loadTrustMaterial(new TrustAllStrategy());
编辑：这个
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
sslcontext, //for you this is builder.build()
SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
);
感谢所有解决方案。我已经尝试了 1.5 天网上提供的所有解决方案，现在终于成功了。这是工作代码
SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(builder.build(), NoopHostnameVerifier.INSTANCE);
Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
.register("http", new PlainConnectionSocketFactory())
.register("https", sslConnectionSocketFactory)
.build();
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
cm.setMaxTotal(100);
CloseableHttpClient httpclient = HttpClients.custom()
.setSSLSocketFactory(sslConnectionSocketFactory)
.setConnectionManager(cm)
.build();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(postEntity);
httpPost.expectContinue();
CloseableHttpResponse response = httpclient.execute(httpPost);
这就是我想到的：
SSLContextBuilder sslcontext = new SSLContextBuilder();
sslcontext.loadTrustMaterial(null, new TrustSelfSignedStrategy());
httpclient = HttpAsyncClients.custom().setSSLContext(sslcontext.build()).setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
.build();
在尝试了本页建议的大部分解决方案以及其他相关的 stackoverflow 讨论后，我发现 AJC 的上述响应适用于 apache httpclient 版本 4.5。
原因： 创建 SSLConnectionSocketFactory 时，如果在构造函数中未指定 HostVerifier，则不会设置它并使用 DefaultHostVerifier。因此，AJC 解决方案的第 3 行发挥了重要作用。
（至少这是 apache httpclient 4.5.3 中的行为）
