Android二进制文件转码到Base64并通过Post进行提交

类似于Ruby,在上面调试成功后,将功能迁移到了Android应用上面。

  Java代码

  import org.apache.http.HttpResponse;

  import org.apache.http.NameValuePair;

  import org.apache.http.client.entity.UrlEncodedFormEntity;

  import org.apache.http.client.methods.HttpPost;

  import org.apache.http.impl.client.DefaultHttpClient;

  import org.apache.http.message.BasicNameValuePair;

  import org.apache.http.protocol.HTTP;

  import android.util.Base64;

  import android.util.Log;

  /**

  * TODO FIX Check the file length, it's long not int.This may lead the

  * problem.

  *

  * @param fileName

  * @param url

  * @return

  */

  public static boolean httpPostBase64(String fileName, String url) {

  try {

  File file = new File(fileName);

  FileInputStream in = new FileInputStream(file);

  byte[] buffer = new byte[(int) file.length() + 100];

  int length = in.read(buffer);

  String data = Base64.encodeToString(buffer, 0, length,

  Base64.DEFAULT);

  HttpPost httpRequest = new HttpPost(url);

  /*

  * NameValuePair实现请求参数的封装

  */

  List params = new LinkedList();

  params.add(new BasicNameValuePair("data", data));

  /* 添加请求参数到请求对象 */

  httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));

  /* 发送请求并等待响应 */

  HttpResponse httpResponse = new DefaultHttpClient()

  .execute(httpRequest);

  /* 若状态码为200 ok */

  if (httpResponse.getStatusLine().getStatusCode() != 200) {

  Log.d("Code", httpResponse.getStatusLine().toString());

  return false;

  }

  } catch (Exception e) {

  for(StackTraceElement s:e.getStackTrace())

 Log.d("Exception",s.toString());

  Log.d("Exception",e.getLocalizedMessage());

  return false;

  }

  return true;

  }
