Java HTTPS 请求工具类

在Java开发中，我们经常需要进行HTTPS请求。为了方便管理和简化代码，我们可以使用工具类来封装HTTPS请求的逻辑。下面就给大家介绍一个简单的Java HTTPS请求工具类，并附上代码示例。

HTTPS请求工具类

import javax.net.ssl.*;
import java.io.*;
import java.net.URL;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class HttpsUtil {

    public static String sendGetRequest(String url) {
        try {
            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) {
                }
            }};

            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());

            URL obj = new URL(url);
            HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

            con.setRequestMethod("GET");

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

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

            in.close();

            return response.toString();
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

使用示例

public class Main {

    public static void main(String[] args) {
        String url = "
        String response = HttpsUtil.sendGetRequest(url);
        System.out.println(response);
    }
}
