我有一个简单的解析器来从Web Api服务获取JSON数据。
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;
}
它有效，但我的问题是，当数据大一点时，它们会被分块！ 当内容较小时，一切工作正常，但在其他方面我得到例外，如“没有价值”。
我使用Restlet查询REST Web Api服务，异常是
Unterminated array at character 13 of [application/json,UTF-8]
我在IIS中发现了一些关于内容长度的问题，但无法找到或理解任何解决方案，有人可以提供帮助，我绝对认为这不是客户端的问题，但我认为我应该专注于服务器端！
