一、第一种方式，通过HttpClient方式，代码如下：

public static String httpGet(String url, String charset)
   throws HttpException, IOException {
  String json = null;
  HttpGet httpGet = new HttpGet();
  // 设置参数
  try {
   httpGet.setURI(new URI(url));
  } catch (URISyntaxException e) {
   throw new HttpException("请求url格式错误。"+e.getMessage());
  }
  // 发送请求
  HttpResponse httpResponse = client.execute(httpGet);
  // 获取返回的数据
  HttpEntity entity = httpResponse.getEntity();
  byte[] body = EntityUtils.toByteArray(entity);
  StatusLine sL = httpResponse.getStatusLine();
  int statusCode = sL.getStatusCode();
  if (statusCode == 200) {
   json = new String(body, charset);
   entity.consumeContent();
  } else {
   throw new HttpException("statusCode="+statusCode);
  }
  return json;
}
