当我尝试通过应用程序从中获取数据时,我的服务器禁止IP 10分钟。 我有2个设备,2个不同的IP。我尝试在浏览器中加载脚本:设备正确加载它。然后我尝试从应用程序请求数据,之后在浏览器中我得到“主机不可用”,但第二个设备仍然正确地在浏览器中加载脚本,直到我尝试直接从应用程序加载数据。 我认为问题出在一些安全设置中,该设置在服务器获得特定数量的请求后自动生成。 这是来自cPanel的日志:
也许在apache设置中存在这样的事情:
if (browser == unknown || OS == unknown)
banIP(360000);
请求代码:
.......
JSONObject json = null;
List<NameValuePair> pn = new ArrayList<NameValuePair>();
pn.add(new BasicNameValuePair("pn", getApplication()
.getPackageName()));
try {
json = jParser.makeHttpRequest(
"http://nastynoises.shunamicode.com/getlastappversion/get_latest_app_version_v2.php","GET", pn);
} catch (Exception e) {
}
.......
请求看起来像:
JsonParser:
makeHttpRequest(){
....
DefaultHttpClient httpClient = new DefaultHttpClient();
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
....
}
服务器返回:

if (!empty($result)) {
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_array($result)) {
$response["success"] = 1;
$response["version"] = $row['version'];
$response["approxdate"] = $row['approxdate'];
echo json_encode($response);
}
} else {
$response["success"] = 0;
$response["message"] = "Package not exist";
echo json_encode($response);
}
} else {
$response["success"] = 0;
$response["message"] = "Empty result";
echo json_encode($response);
}
} else {
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
echo json_encode($response);
}
?>
我尝试删除所有脚本并再次请求,但服务器仍然禁止。 我没有太多练习,这个错误让我陷入僵局。
答案 0 :(得分:1)
我找到了解决方案。现在我的应用程序工作正常,像以前一样但它不能成为问题的答案,它是一个旁路: 当我设置BasicHttpParams()时服务器返回响应,所以JSONParser现在工作:
....
int TIMEOUT_MILLISEC = 10000;
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient httpClient = new DefaultHttpClient(httpParams);
....
问题仍未解决
