java post请求跳过证书验证

在Java中发送POST请求并跳过证书验证，可以使用HttpsURLConnection类的一些方法来实现。以下是一种示例代码，其中使用了TrustManager和HostnameVerifier来跳过证书验证：

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.security.cert.X509Certificate;

public class HttpsPost {

    public static void main(String[] args) throws Exception {

        String url = "https://example.com/api";
        String data = "param1=value1&param2=value2";

        // Create a trust manager that does not validate certificate chains
        TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    public X509Certificate[] getAcceptedIssuers() {
                        return null;
                    }

                    public void checkClientTrusted(X509Certificate[] certs, String authType) {
                    }

                    public void checkServerTrusted(X509Certificate[] certs, String authType) {
                    }
                }
        };

        // Install the all-trusting trust manager
        SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());

        // Create all-trusting host name verifier
        HostnameVerifier allHostsValid = (hostname, session) -> true;

        // Install the all-trusting host verifier
        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);

        // Send POST request
        URL obj = new URL(url);
        HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
        con.setRequestMethod("POST");
        con.setDoOutput(true);
        con.getOutputStream().write(data.getBytes("UTF-8"));

        // Get response
        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuilder response = new StringBuilder();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        // Print response
        System.out.println(response.toString());
    }
}

在上面的代码中，我们创建了一个TrustManager，该TrustManager不验证证书链。然后，我们使用该TrustManager创建了一个SSLContext，并将其设置为默认的SSLSocketFactory。接下来，我们创建了一个HostnameVerifier，该Verifier接受所有主机名，并将其设置为默认的HostnameVerifier。最后，我们使用HttpsURLConnection类来发送POST请求，该请求将跳过证书验证。
