Java下载https文件并上传阿里云oss服务器

这篇文章主要介绍了Java下载https文件并上传到阿里云oss服务器,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

今天做了一个从Https链接中下载音频并且上传到OSS服务器，记录一下希望大家也少走弯路。

一共两个类：

1 、实现自己的证书信任管理器类

/**
 * @author mazhq
 * @Title: X509TrustUtiil
 * @ProjectName: zeus
 * @Description: 证书信任管理器类
 * @date 2019/2/18 15:14
 */
public class X509TrustUtil implements X509TrustManager {
  @Override
  public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
  }
  @Override
  public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {

  }

  @Override
  public X509Certificate[] getAcceptedIssuers() {
    return new X509Certificate[0];
  }
}

2、阿里云上传工具类

/**
 * @author mazhq
 * @Title: OSSUtil
 * @ProjectName: zeus
 * @Description: TODO
 * @date 2019/2/18 14:07
 */
public class OSSUtil {
  /**
  * @Description: 上传文件到阿里云
  * @param recordingLink
  * @param fileName
  * @return void
  * @exception
  * @author mazhq
  * @date 2019/2/18 14:30
  */
  public static String uploadRecording(JSONObject ossJson, String recordingLink, String fileName){
    try {
      // Endpoint以杭州为例，其它Region请按实际情况填写。
      String endpoint = "";

      String bucketServer;
      String bucketName;
      bucketName = "dev-uploadtoimages";
      endpoint = "http://oss-devimage.xxxx.com/";
      bucketServer = "http://dev-uploadtoimages.oss-cn-beijing.aliyuncs.com/";

      // 阿里云主账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建RAM账号。
      String accessKeyId = ossJson.getString("accessKeyId");
      String accessKeySecret = ossJson.getString("accessKeySecret");
      String security = ossJson.getString("security");

      // 创建OSSClient实例。
      OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret, security);

      // 上传网络流。
      SSLContext sslcontext = SSLContext.getInstance("SSL", "SunJSSE");
      sslcontext.init(null, new TrustManager[] { new X509TrustUtil() }, new java.security.SecureRandom());
      URL url = new URL(recordingLink);
      HostnameVerifier ignoreHostnameVerifier = new HostnameVerifier() {
        public boolean verify(String s, SSLSession sslsession) {
          System.out.println("WARNING: Hostname is not matched for cert.");
          return true;
        }
      };
      HttpsURLConnection.setDefaultHostnameVerifier(ignoreHostnameVerifier);
      HttpsURLConnection.setDefaultSSLSocketFactory(sslcontext.getSocketFactory());
      HttpsURLConnection urlCon = (HttpsURLConnection) url.openConnection();
      urlCon.setConnectTimeout(6000);
      urlCon.setReadTimeout(6000);
      int code = urlCon.getResponseCode();
      if (code != HttpURLConnection.HTTP_OK) {
        throw new Exception("文件读取失败");
      }
      // 读文件流
      InputStream inputStream = urlCon.getInputStream();

      // 上传文件 (上传文件流的形式)
      ossClient.putObject(bucketName, "recording/"+fileName, inputStream);

      // 关闭OSSClient。
      ossClient.shutdown();

      return bucketServer+"recording/"+fileName;
    } catch (IOException e) {
      e.printStackTrace();
    }catch (Exception e){
      e.printStackTrace();
    }

    return null;
  }

}

结论：

两个类搭配着用，完美解决下载https文件上传到阿里oss返回上传之后路径。
