Android客户端主要代码：

public ImageHttp(Context context) {		super(context);		filePath = context.getCacheDir().getAbsolutePath();	}	public void uploadUserImg(Bitmap bitmap,			IHttpSenderCallBack<String> callback) {		this.callback = callback;		File file = getFile(bitmap);		// 注意与服务端协商		if (file == null) {			return;		}		List<Parameter> parameters = new ArrayList<Parameter>();		parameters.add(new Parameter("file", file));		uploadFile("uploadImg", parameters);	}	private File getFile(Bitmap bitmap) {		File file = null;		String path = filePath + "/image.jpg";		if (bitmap != null && !StringUtil.emptyOrNull(path)) {			try {				FileOutputStream out = new FileOutputStream(path);				bitmap.compress(Bitmap.CompressFormat.JPEG, 60, out);				out.flush();				out.close();				file = new File(path);			} catch (FileNotFoundException e) {				e.printStackTrace();			} catch (Exception e) {				e.printStackTrace();			}		}		return file;	}

protected String uploadFile(String methodName, List<Parameter> parameter) {		String errorMsg = "";		try {			String serviceUrl = getPostUrl(methodName);			HttpPost httpPost = new HttpPost(serviceUrl);			//采用http4包，不需要再添加  multipart/form-data表单 ，切记，这儿耽搁了好久			MultipartEntity mpEntity = new MultipartEntity(					HttpMultipartMode.BROWSER_COMPATIBLE); // 文件传输			if (parameter != null && !parameter.isEmpty()) {				for (int i = 0; i < parameter.size(); i++) {					Parameter p = parameter.get(i);					if ("file".equals(p.getKey())) {						mpEntity.addPart(p.getKey(),								new FileBody(((File) p.getValue())));					} else {						mpEntity.addPart(p.getKey(), new StringBody(p								.getValue().toString()));					}				}				httpPost.setEntity(mpEntity);			}			HttpClient httpclient = new DefaultHttpClient();			httpclient.getParams().setParameter(					CoreConnectionPNames.CONNECTION_TIMEOUT, TIMEOUT);			httpclient.getParams().setParameter(					CoreConnectionPNames.SO_TIMEOUT, TIMEOUT);			HttpResponse httpResponse = httpclient.execute(httpPost);			String result = "";			int status = httpResponse.getStatusLine().getStatusCode();			LogUtil.d("httpResponseCode--------->" + status);			if (status == HttpStatus.SC_OK) {				result = EntityUtils.toString(httpResponse.getEntity());			}			parseProperty_(result, methodName);			result = "";		} catch (UnsupportedEncodingException e) {			e.printStackTrace();		} catch (ClientProtocolException e) {			e.printStackTrace();		} catch (IOException e) {			e.printStackTrace();		} catch (Exception e) {			e.printStackTrace();		}		return errorMsg;	}
