注意一般使用Http协议上传的文件都比较小,一般是小于2M
这里示例是上传一个小的MP3文件
1.主Activity:MainActivity.java
- public class MainActivity extends Activity
- {
- private static final String TAG = "MainActivity";
- private EditText timelengthText;
- private EditText titleText;
- private EditText videoText;
- @Override
- public void onCreate(Bundle savedInstanceState)
- {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- //提交上传按钮
- Button button = (Button) this.findViewById(R.id.button);
- timelengthText = (EditText) this.findViewById(R.id.timelength);
- videoText = (EditText) this.findViewById(R.id.video);
- titleText = (EditText) this.findViewById(R.id.title);
- button.setOnClickListener(new View.OnClickListener()
- {
- @Override
- public void onClick(View v)
- {
- String title = titleText.getText().toString();
- String timelength = timelengthText.getText().toString();
- Map<String, String> params = new HashMap<String, String>();
- params.put("method", "save");
- params.put("title", title);
- params.put("timelength", timelength);
- try
- {
- //得到SDCard的目录
- File uploadFile = new File(Environment.getExternalStorageDirectory(), videoText.getText().toString());
- //上传音频文件
- FormFile formfile = new FormFile("02.mp3", uploadFile, "video", "audio/mpeg");
- SocketHttpRequester.post("http://192.168.1.100:8080/videoweb/video/manage.do", params, formfile);
- Toast.makeText(MainActivity.this, R.string.success, 1).show();
- }
- catch (Exception e)
- {
- Toast.makeText(MainActivity.this, R.string.error, 1).show();
- Log.e(TAG, e.toString());
- }
- }
- });
- }
- }
2.上传工具类,注意里面构造协议字符串需要根据不同的提交表单来处理
- public class SocketHttpRequester
- {
- /**

- * @param path 请求地址
- * @param xml xml数据
- * @param encoding 编码
- *

- byte[] data = xml.getBytes(encoding);
- URL url = new URL(path);
- HttpURLConnection conn = (HttpURLConnection)url.openConnection();
- conn.setRequestMethod("POST");
- conn.setDoOutput(true);
- conn.setRequestProperty("Content-Type", "text/xml; charset="+ encoding);
- conn.setRequestProperty("Content-Length", String.valueOf(data.length));
- conn.setConnectTimeout(5 * 1000);
- OutputStream outStream = conn.getOutputStream();
- outStream.write(data);
- outStream.flush();
- outStream.close();
- if(conn.getResponseCode()==200){
- return readStream(conn.getInputStream());
- }
- return null;
- }
