Andriod调用http请求

　　　　　　　　　　// 新建HttpPost对象
		HttpPost httpPost = new HttpPost(
				"http://180.153.1.1:8080/mybankGateway/gateway/queryProductType");

		// 参数列表
		List<NameValuePair> params = new ArrayList<NameValuePair>();
		params.add(new BasicNameValuePair("query", "工作日"));

		// 设置字符集
		HttpEntity entity = null;
		try {
			entity = new UrlEncodedFormEntity(params, HTTP.UTF_8);
		} catch (UnsupportedEncodingException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		// 设置参数实体
		httpPost.setEntity(entity);
		// 获取HttpClient对象
		HttpClient httpClient = new DefaultHttpClient();
		// 连接超时
		httpClient.getParams().setParameter(
				CoreConnectionPNames.CONNECTION_TIMEOUT, 30000);
		// 请求超时
		httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,
				30000);
		try {
			// 获取HttpResponse实例
			HttpResponse httpResp = httpClient.execute(httpPost);
			// 判断是够请求成功
			if (httpResp.getStatusLine().getStatusCode() == 200) {
				// 获取返回的数据
				String result = EntityUtils.toString(httpResp.getEntity(),
						"UTF-8");
				Log.i("HttpPost", "HttpPost方式请求成功，返回数据如下：");
				Log.i("result", result);
				System.err.println(result);
			} else {
				Log.i("HttpPost", "HttpPost方式请求失败");
			}
		} catch (ConnectTimeoutException e) {
			e.printStackTrace();
