支持https 但不验证证书的 Httpclient 工具类

末蓝、 2022-05-21 01:17 189阅读 0赞

情况是这样的，公司是做支付业务的，所以有异步通知订单的业务，商户有https，http 都有的

但是有一些商户的https 一个证书对应多个域名的情况，亦或者自建证书，所有我们需要修改成视情况而定的放弃证书的校验

下面直接提出工具类

SSLClient 跳过证书校验返回 CloseableHttpClient

package http;
    import java.security.cert.CertificateException;
    import java.security.cert.X509Certificate;
    
    import javax.net.ssl.SSLContext;
    import javax.net.ssl.TrustManager;
    import javax.net.ssl.X509TrustManager;
    
    import org.apache.http.conn.ClientConnectionManager;
    import org.apache.http.conn.scheme.Scheme;
    import org.apache.http.conn.scheme.SchemeRegistry;
    import org.apache.http.conn.ssl.SSLSocketFactory;
    import org.apache.http.impl.client.DefaultHttpClient;  
    //用于进行Https请求的HttpClient  
    public class SSLClient extends DefaultHttpClient{  
        public SSLClient() throws Exception{  
            super();  
            SSLContext ctx = SSLContext.getInstance("TLS");  
            X509TrustManager tm = 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 null;  
                    }  
            };  
            ctx.init(null, new TrustManager[]{tm}, null);  
            //允许所有证书
            SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);  
            ClientConnectionManager ccm = this.getConnectionManager();  
            SchemeRegistry sr = ccm.getSchemeRegistry();  
            sr.register(new Scheme("https", 443, ssf));  
        }  
    }

HTTP请求工具类，这个工具类基本的请求都包含了，也可以自行添加修改发送方式，如body方式等

目前是json 和map 的两种方式 有校验证书的，有不校验证书的，根据方法名就可以看出
