菜鸟求救 安卓http请求乱码问题

[放纵的青春]

刚玩安卓
安卓项目中用http请求去请求一个web服务器
传过去的参数服务器接收是乱码
用浏览器访问中文正常

	/**
	 * Get请求
	 * 
	 * @param url
	 *            请求地址
	 * @param params
	 *            参数
	 * @return
	 */
	public static String httpGet(String url, Map<String, String> params) {
		StringBuilder sb = new StringBuilder();
		sb.append(url).append("?");
		for (String key : params.keySet()) {
			sb.append(key).append("=").append(params.get(key)).append("&");
		}

		url = sb.substring(0, sb.length() - 1);
		return openUrl(url);
	}

	/**
	 * 连接失败
	 */
	public static final String CONNECT_FAILED = "url request error";

	/**
	 * @param url
	 *            请求地址
	 * @return 返回结果
	 */
	public static String openUrl(String url) {
		HttpURLConnection c = null;
		try {
			StringBuffer sb = new StringBuffer();
			URL u = new URL(url);
			c = (HttpURLConnection) u.openConnection();
			if (c == null) {
				return CONNECT_FAILED;
			}
			BufferedReader br = new BufferedReader(new InputStreamReader(
					c.getInputStream()));
			int byteRead = 0;
			char[] buffer = new char[8192];
			while ((byteRead = br.read(buffer, 0, 8192)) != -1) {
				sb.append(buffer, 0, byteRead);
			}
			return sb.toString();
		} catch (Exception e) {
			System.out.println("http请求出错:" + url);
			return CONNECT_FAILED;
		} finally {
			if (c != null) {
				c.disconnect();
			}
		}
	}

	// 调用http接口查询仓库信息
		Map<String, String> params = new HashMap<String, String>();
		params.put("wareInfoName", wareInfoName);
		String xml = HttpUtil.httpGet(url, params);
