如何使用.net在Amzon中使用Selling-partner-api加密和上传数据

问题描述

我想对.Net使用Selling-partner-api-docs。我从url下面找到了一个引用，但这是使用Java示例编码的：https://github.com/amzn/selling-partner-api-docs/blob/main/guides/use-case-guides/feeds-api-use-case-guide-2020-09-04.md#step-2-encrypt-and-upload-the-feed-data

但是我想使用.Net编码可以建议下面Java编码部分的.Net编码

    import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.PipedInputStream;
import java.io.PipedOutputStream;
import java.nio.charset.StandardCharsets;

import com.amazon.spapi.documents.UploadHelper;
import com.amazon.spapi.documents.UploadSpecification;
import com.amazon.spapi.documents.exception.CryptoException;
import com.amazon.spapi.documents.exception.HttpResponseException;
import com.amazon.spapi.documents.impl.AESCryptoStreamFactory;

/* We want to maintain encryption at rest,so do not write unencrypted data to disk.  This is bad:
InputStream source = new FileInputStream(new File("/path/to/myFeed.xml"));

Instead,if your data can fit in memory,you can create an InputStream from a String (see encryptAndUpload_fromString()).
Otherwise,you can pipe data into an InputStream using Piped streams (see encryptAndUpload_fromPipedInputStream()).
 */
public class UploadExample {
  private final UploadHelper uploadHelper = new UploadHelper.Builder().build();

  // key,initializationVector,and url are returned by the createFeedDocument operation.
  public void encryptAndUpload_fromString(String key,String initializationVector,String url) {
    AESCryptoStreamFactory aesCryptoStreamFactory =
      new AESCryptoStreamFactory.Builder(key,initializationVector)
      .build();

    // This contentType must be the same value that was provided to createFeedDocument.
    String contentType = String.format("text/plain; charset=%s",StandardCharsets.UTF_8);

    // The character set must be the same one that is specified in contentType.
    try
      (InputStream source = new ByteArrayInputStream("my feed data".getBytes(StandardCharsets.UTF_8))) {
        UploadSpecification uploadSpec =
          new UploadSpecification.Builder(contentType,aesCryptoStreamFactory,source,url)
          .build();

        uploadHelper.upload(uploadSpec);
      }
    catch (CryptoException | HttpResponseException | IOException e) {
      // Handle exception.
    }
  }

  // key,and url are returned from createFeedDocument.
  public void encryptAndUpload_fromPipedInputStream(String key,StandardCharsets.UTF_8);

    try
      (PipedInputStream source = new PipedInputStream()) {
        new Thread(
          new Runnable() {
          public void run() {
            try
              (PipedOutputStream feedContents = new PipedOutputStream(source)) {
                // The character set must be the same one that is specified in contentType.
                feedContents.write("my feed data\n".getBytes(StandardCharsets.UTF_8));
                feedContents.write("more feed data".getBytes(StandardCharsets.UTF_8));
              }
            catch (IOException e) {
              // Handle exception.
            }
          }
        }).start();

        UploadSpecification uploadSpec =
          new UploadSpecification.Builder(contentType,url)
          .build();

        uploadHelper.upload(uploadSpec);
      }
    catch (CryptoException | HttpResponseException | IOException e) {
    
    }
  }
}
