java 自定义证书路径的https请求

您可以使用Java的HttpsURLConnection类来发出自定义证书路径的HTTPS请求。以下是一个示例代码：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManagerFactory;
import java.io.FileInputStream;
import java.security.KeyStore;

public class CustomCertHttpsRequest {
    public static void main(String[] args) throws Exception {
        // 证书路径
        String certPath = "/path/to/certificate.pem";
        // 证书密码
        String certPassword = "password";
        // 请求URL
        String url = "https://example.com";

        // 加载证书
        KeyStore keyStore = KeyStore.getInstance("JKS");
        FileInputStream fis = new FileInputStream(certPath);
        keyStore.load(fis, certPassword.toCharArray());

        // 创建TrustManagerFactory
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(keyStore);

        // 创建SSLContext
        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(null, tmf.getTrustManagers(), null);

        // 创建HttpsURLConnection
        URL requestUrl = new URL(url);
        HttpsURLConnection conn = (HttpsURLConnection) requestUrl.openConnection();
        conn.setSSLSocketFactory(sslContext.getSocketFactory());

        // 发送HTTPS请求
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
        }
        in.close();
    }
}

在上面的代码中，我们首先定义证书路径和密码。然后，我们加载证书文件，并使用TrustManagerFactory和SSLContext创建一个安全连接。最后，我们创建HttpsURLConnection，将证书套接字工厂设置为SSLContext的套接字工厂，并使用openConnection()方法发送HTTPS请求。

请注意，如果您使用的是自签名证书，则需要在加载证书之前禁用主机名验证。例如：

HttpsURLConnection.setDefaultHostnameVerifier((hostname, sslSession) -> true);
