使用阿里云OSS上传图片

与ios的阿里云上传图片类似，目前是也刚接触android开发时间不长，在此记录一下

1.从后台服务器获取keyId、keySecret、token

此处省略。我们后台同时返回给我path图片在阿里云存储位置

2.android代码实现

2.1第一步先实现一个数据返回接口

import com.alibaba.sdk.android.oss.model.PutObjectResult;

  public  interface AliyunOSSCallBack {

        public void oSSRequestSuccess(PutObjectResult object);

        public void oSSRequestFailure(String errorCode,String msg);

}

2.2代码实现

public class AliyunOSSUtils {

    // 访问的endpoint地址
    public static final String OSS_ENDPOINT = "http://oss-cn-zhangjiakou.aliyuncs.com";
    public static final String BUCKET_NAME = "test";

 
    private static OSS oss;

    protected AliyunOSSCallBack ossCallBack;
    private OSSAsyncTask task;

    public void setOsstoken(String keyid, String keysecret, String token) {
        OSSCredentialProvider provider = new OSSStsTokenCredentialProvider(keyid, keysecret,token);
        ClientConfiguration conf = new ClientConfiguration();
        conf.setConnectionTimeout(15 * 1000); // 连接超时，默认15秒
        conf.setSocketTimeout(15 * 1000); // socket超时，默认15秒
        conf.setMaxConcurrentRequest(5); // 最大并发请求书，默认5个
        conf.setMaxErrorRetry(2); // 失败后最大重试次数，默认2次
        oss = new OSSClient(MainApplication.getAppCtx(), OSS_ENDPOINT, provider, conf);
    }
  /**
   * 同步上传单个文件
   *
   * @param name
   * @param localPath
 */
  public void uploadFile(String name, String localPath,final AliyunOSSCallBack callBack) {

        ossCallBack = callBack;
        // 构造上传请求。
        PutObjectRequest put = new PutObjectRequest(BUCKET_NAME, name, localPath);
        try {
            PutObjectResult putResult = oss.putObject(put);
            ossCallBack.oSSRequestSuccess(putResult);
        } catch (ClientException e) {
            // 本地异常，如网络异常等。
            e.printStackTrace();
            ossCallBack.oSSRequestFailure("",e.getMessage());
      } catch (ServiceException e) {
        // 服务异常。
        ossCallBack.oSSRequestFailure(e.getErrorCode(),e.getRawMessage());
     }
 }

/**
 * 异步上传单个文件
 *
 * @param name
 * @param localPath
 */
public void asynploadFile(String name, String localPath) {
    // 构造上传请求。
    PutObjectRequest put = new PutObjectRequest(BUCKET_NAME, name, localPath);
    // 异步上传时可以设置进度回调。
    put.setProgressCallback(new OSSProgressCallback<PutObjectRequest>() {
        @Override
        public void onProgress(PutObjectRequest request, long currentSize, long totalSize) {
            Log.d("PutObject", "currentSize: " + currentSize + " totalSize: " + totalSize);

        }
    });

    task = oss.asyncPutObject(put, new OSSCompletedCallback<PutObjectRequest, PutObjectResult>() {
        @Override
        public void onSuccess(PutObjectRequest request, PutObjectResult result) {
            Log.d("PutObject", "UploadSuccess");
            ossCallBack.oSSRequestSuccess(result);
        }

        @Override
        public void onFailure(PutObjectRequest request, ClientException clientExcepion, ServiceException serviceException) {
            // Request exception
            if (clientExcepion != null) {
                // Local exception, such as a network exception
                clientExcepion.printStackTrace();
                ossCallBack.oSSRequestFailure("",clientExcepion.getMessage());
            }
            if (serviceException != null) {
              ossCallBack.oSSRequestFailure(serviceException.getErrorCode(),serviceException.getRawMessage());
            }
        }
    });
    // task.cancel(); // Cancel the task
    // task.waitUntilFinished(); // Wait till the task is finished
}

/**
 * 取消异步请求
 *
 * @param
 */
public void asynCancel(){
    if(task != null && task.isCanceled()){
        task.cancel();
    }
}

}
