Question

我得到一个例外：

java.lang.Boolean无法转换为JSONObject

如何删除此例外？

HttpGet request = new
    HttpGet("http://xxxxxxxxxxxx/REST/MobileService.svcisApproved?DeviceID=123");
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
HttpEntity responseEntity = response.getEntity();
String changeTIDRec = EntityUtils.toString(responseEntity);
JSONObject jsonResponse = new JSONObject(changeTIDRec);

您需要这种方法：

 private static String convertStreamToString(InputStream is) {

BufferedReader reader = new BufferedReader(
    new InputStreamReader(is));
StringBuilder sb = new StringBuilder();

String line = null;
try {
    while ((line = reader.readLine()) != null) {
    sb.append(line + "\n");
    }
} catch (IOException e) {
    // Log.e(TAG, e.getMessage(), e);
    throw new RuntimeException(e.getMessage(), e);
} finally {
    try {
    is.close();
    } catch (IOException e) {
    // Log.e(TAG, e.getMessage(), e);
    throw new RuntimeException(e.getMessage(), e);
    }
}
return sb.toString();
}

它的使用方式如下：

InputStream instream = entity.getContent();
        response = convertStreamToString(instream);

为什么不使用Gson：

String test = "test string";
Gson gson = new Gson();
gson.toJson(test);

如何将String转换为JSON OBJECT
