我使用的是WSO2 API Manager 1.9.1版.在这个工具中,我发布了我的示例项目(即代理)并订??阅该项目以获取消费者密钥和秘密.这个工具也给了我CURL命令,它工作正常.

下面的CURL命令运行正常.

curl -k -d "grant_type=password&username=XXXXX&password=XXXXX" -H "Authorization: Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX, Content-Type: application/x-www-form-urlencoded" https://XXXXXXXXXXX:XXXX/token

现在我正在尝试使用RestTemplate开发java代码,它将连接到受SSL保护的站点而无需验证,即查看上面的CURL命令的不安全方式.
到目前为止,我开发了以下代码,但是当我运行时,我看到以下错误.

public static void main(String[] args) {
        HttpHeaders headers = new HttpHeaders();
        headers.add("Accept", "application/json");
        headers.add("Content-Type", MediaType.APPLICATION_FORM_URLENCODED.toString());
        headers.add("Authorization", "Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");

        String url = "https://XXXXXXXXXXXXXX:XXXX/token";

        String data = "grant_type=password&username=XXXXX&password=XXXXX";

        RestTemplate restTemplate = new RestTemplate();
        HttpEntity<String> entity = new HttpEntity<String>(data,headers);
        HttpEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, entity, String.class);
        System.out.println("RESPONSE : "+response.getBody());
    }

我面临的错误.请建议我们如何连接到SSL站点不安全的方式,同样的curl命令呢？

我们如何解决这个错误？偏离我的问题与javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names present不相似

解决方法:

通过应用以下代码可以解决以下问题,这些代码以不安全的方式连接到受SSL保护的站点. (注意：要使用cert enable连接到SSL站点,您需要添加tomcat SSL配置).

以下代码工作正常.

import java.security.NoSuchAlgorithmException;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;

    }

    private static void disableSslVerification() {
        try{
            // Create a trust manager that does not validate certificate chains
            TrustManager[] trustAllCerts = new TrustManager[] {new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {

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

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

            HostnameVerifier allHostsValid = new HostnameVerifier() {

                    return true;
                }
            };

            // Install the all-trusting host verifier
            HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        HttpHeaders headers = new HttpHeaders();
        headers.add("Accept", "application/json");
        headers.add("Content-Type", MediaType.APPLICATION_FORM_URLENCODED.toString());
        headers.add("Authorization", "Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXX");

        String url = "https://XXXXXXXXXXXXX:XXXX/token";

        String dataJSON = "grant_type=password&username=XXXXX&password=XXXXX";

        RestTemplate restTemplate = new RestTemplate();
        HttpEntity<String> entity = new HttpEntity<String>(dataJSON,headers);
        HttpEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, entity, String.class);
        System.out.println("O/P : "+response.getBody());
    }
