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 个具有 2 个不同 IP 的设备。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”，但第二台设备仍然在浏览器中正确加载脚本，直到我尝试直接从应用程序加载数据。我认为问题出在某些安全设置中，该设置在服务器获得特定数量的请求后自动进行。这是来自 cPanel 的日志：

面板日志

也许在 apache 设置中存在这样的东西：

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) {
        }
.......

使请求看起来像：

http://nastynoises.shunamicode.com/getlastappversion/get_latest_app_version_v2.php?pn=com.shunamicode.nn

json解析器：

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：

php:

<?php
$response = array();
require_once __DIR__ . '/con.php';
$db = new DB_CONNECT();
if (isset($_GET["pn"])) {
    $result = mysql_query("SELECT * FROM `latest_versions` WHERE `package_name` = '".$_GET["pn"]."'");
    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);
}
?>

我试图删除所有脚本并再次请求，但服务器仍然禁止。我没有很多练习，这个错误使我陷入僵局。

我找到了解决方案。现在我的应用程序工作正常，就像以前一样。但它不能成为问题的答案，它是一个绕过：当我设置 BasicHttpParams() 时服务器返回响应，所以 JSONParser 现在可以工作了：

....
int TIMEOUT_MILLISEC = 10000; 
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
                    TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient httpClient = new DefaultHttpClient(httpParams);
....

问题仍然悬而未决
