使用Jackson(Java)正确地打开多个URL的SSL流可以按照以下步骤进行操作:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.12.4</version>
</dependency>
import javax.net.ssl.*;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
public class SSLUtil {
public static void trustAllCertificates() throws NoSuchAlgorithmException, KeyManagementException {
// 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) throws CertificateException {}
}
};
// Install the all-trusting trust manager
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
// Bypass hostname verification
HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> true);
}
}
SSLUtil.trustAllCertificates()
方法来信任所有证书,以避免SSL验证错误。然后,可以使用Jackson的ObjectMapper
类来打开URL并读取数据,如下所示:import com.fasterxml.jackson.databind.ObjectMapper;
import javax.net.ssl.HttpsURLConnection;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
public class Main {
public static void main(String[] args) {
try {
SSLUtil.trustAllCertificates(); // 信任所有证书
ObjectMapper objectMapper = new ObjectMapper();
URL url = new URL("https://example.com/api/data");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setRequestMethod("GET");
try (InputStream inputStream = connection.getInputStream()) {
// 从输入流中读取数据并进行处理
MyDataObject dataObject = objectMapper.readValue(inputStream, MyDataObject.class);
// 进行其他操作...
}
} catch (IOException | NoSuchAlgorithmException | KeyManagementException e) {
e.printStackTrace();
}
}
}
请注意,这只是使用Jackson(Java)正确地打开多个URL的SSL流的基本示例。实际应用中,可能还需要进行错误处理、数据解析和其他相关操作。
