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<br /> {<br /> private static final String TAG = "MainActivity";<br /> private EditText timelengthText;<br /> private EditText titleText;<br /> private EditText videoText;</p> <p> @Override<br /> public void onCreate(Bundle savedInstanceState)<br /> {<br /> super.onCreate(savedInstanceState);<br /> setContentView(R.layout.main);<br /> //提交上传按钮<br /> Button button = (Button) this.findViewById(R.id.button);<br /> timelengthText = (EditText) this.findViewById(R.id.timelength);<br /> videoText = (EditText) this.findViewById(R.id.video);<br /> titleText = (EditText) this.findViewById(R.id.title);<br /> button.setOnClickListener(new View.OnClickListener()<br /> {<br /> @Override<br /> public void onClick(View v)<br /> {<br /> String title = titleText.getText().toString();<br /> String timelength = timelengthText.getText().toString();<br /> Map<String, String> params = new HashMap<String, String>();<br /> params.put("method", "save");<br /> params.put("title", title);<br /> params.put("timelength", timelength);<br /> try<br /> {<br /> //得到SDCard的目录<br /> File uploadFile = new File(Environment.getExternalStorageDirectory(), videoText.getText().toString());<br /> //上传音频文件<br /> FormFile formfile = new FormFile("02.mp3", uploadFile, "video", "audio/mpeg");<br /> SocketHttpRequester.post("http://192.168.1.100:8080/videoweb/video/manage.do", params, formfile);<br /> Toast.makeText(MainActivity.this, R.string.success, 1).show();<br /> }<br /> catch (Exception e)<br /> {<br /> Toast.makeText(MainActivity.this, R.string.error, 1).show();<br /> Log.e(TAG, e.toString());<br /> }<br /> }<br /> });<br /> }<br /> } 

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<br /> {<br /> /**<br /> * 发送xml数据<br /> * @param path 请求地址<br /> * @param xml xml数据<br /> * @param encoding 编码<br /> * @return<br /> * @throws Exception<br /> */<br /> public static byte[] postXml(String path, String xml, String encoding) throws Exception{<br /> byte[] data = xml.getBytes(encoding);<br /> URL url = new URL(path);<br /> HttpURLConnection conn = (HttpURLConnection)url.openConnection();<br /> conn.setRequestMethod("POST");<br /> conn.setDoOutput(true);<br /> conn.setRequestProperty("Content-Type", "text/xml;
