Java客户端无法从wcf rest服务读取大响应

我正在尝试使用android 2.1上的java客户端使用rest WCF服务。 它对小的响应非常有效。当我试图通过获得1000多个字符的响应读卡器来进一步推进时，read（buffer）无法读取所有字符。这导致脚本的最后一行返回：字符8193“{plate

我的android设备在仿真器android启动之前就开始出现此错误（字符1194而不是8193）。有人知道如何获取完整消息吗

客户端代码：

HttpGet request = new HttpGet(SERVICE_URI + "/GetPlates");
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
HttpEntity responseEntity = response.getEntity();
char[] buffer = new char[(int)responseEntity.getContentLength()];
InputStream stream = responseEntity.getContent();
InputStreamReader reader = new InputStreamReader(stream);
reader.read(buffer);
stream.close();         
JSONArray plates = new JSONArray(new String(buffer));

服务器配置：

<webHttpBinding>
    <binding name="big_webHttpBinding" maxReceivedMessageSize="4097152" maxBufferSize="4097152" maxBufferPoolSize="4097152">
      <readerQuotas maxStringContentLength="4097152" maxArrayLength="4097152" maxBytesPerRead="4097152" maxNameTableCharCount="4097152" maxDepth="4097152"/>
    </binding>
  </webHttpBinding>

而不是

char[] buffer = new char[(int)responseEntity.getContentLength()];
InputStream stream = responseEntity.getContent();
InputStreamReader reader = new InputStreamReader(stream);
reader.read(buffer);
stream.close(); 

这样做：

String jsonText = EntityUtils.toString(responseEntity, HTTP.UTF_8);

而不是

char[] buffer = new char[(int)responseEntity.getContentLength()];
InputStream stream = responseEntity.getContent();
InputStreamReader reader = new InputStreamReader(stream);
reader.read(buffer);
stream.close(); 

这样做：

String jsonText = EntityUtils.toString(responseEntity, HTTP.UTF_8);
