我有一个简单的解析器来从Web Api服务获取JSON数据。Web Api上的Android REST请求，JSON响应被分块
public JSONArray getJSONArrayFromUrl(String url) {
InputStream is = null;
JSONArray jObj = null;
String json = "";
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
//json += line;
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONArray(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
它的工作原理，但我的问题是，当数据稍大，他们得到大块！ 当内容较小时，一切工作正常，但以其他方式，我得到“没有任何价值”的异常。
我用的Restlet查询REST的Web API服务和例外是
Unterminated array at character 13 of [application/json,UTF-8]
我发现有关内容的长度有一定的问题，在IIS中，但无法找到或理解任何sollutions的，有人能帮助，我绝对认为这不是客户的问题，但我认为我应该关注服务器端！
