這篇文章主要介紹了Java下載https檔案並上傳到阿里雲oss伺服器,文中通過示例程式碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值,需要的朋友可以參考下

今天做了一個從Https連結中下載音訊並且上傳到OSS伺服器，記錄一下希望大家也少走彎路。

一共兩個類：

1 、實現自己的證書信任管理器類

/**
 * @author mazhq
 * @Title: X509TrustUtiil
 * @ProjectName: zeus
 * @Description: 證書信任管理器類
 * @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、阿里雲上傳工具類

/**
 * @author mazhq
 * @Title: OSSUtil
 * @ProjectName: zeus
 * @Description: TODO
 * @date 2019/2/18 14:07
 */
public class OSSUtil {
  /**
  * @Description: 上傳檔案到阿里雲
  * @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以杭州為例，其它Region請按實際情況填寫。
      String endpoint = "";
 
      String bucketServer;
      String bucketName;
      bucketName = "dev-uploadtoimages";
      endpoint = "http://oss-devimage.xxxx.com/";
      bucketServer = "http://dev-uploadtoimages.oss-cn-beijing.aliyuncs.com/";
 
      // 阿里雲主賬號AccessKey擁有所有API的訪問許可權，風險很高。強烈建議您建立並使用RAM賬號進行API訪問或日常運維，請登入 https://ram.console.aliyun.com 建立RAM賬號。
      String accessKeyId = ossJson.getString("accessKeyId");
      String accessKeySecret = ossJson.getString("accessKeySecret");
      String security = ossJson.getString("security");
 
      // 建立OSSClient例項。
      OSSClient ossClient = new OSSClient(endpoint,accessKeyId,accessKeySecret,security);
 
      // 上傳網路流。
      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("檔案讀取失敗");
      }
      // 讀檔案流
      InputStream inputStream = urlCon.getInputStream();
 
      // 上傳檔案 (上傳檔案流的形式)
      ossClient.putObject(bucketName,"recording/"+fileName,inputStream);
 
      // 關閉OSSClient。
      ossClient.shutdown();
 
      return bucketServer+"recording/"+fileName;
    } catch (IOException e) {
      e.printStackTrace();
    }catch (Exception e){
      e.printStackTrace();
    }
 
    return null;
  }
 
}

結論：

兩個類搭配著用，完美解決下載https檔案上傳到阿里oss返回上傳之後路徑。
