Android-尝试连接到本地服务器(Xampp)时出错 [英] Android - error while try connect to local server(Xampp)

问题描述

这是我的logcat和我尝试连接的网址的第一行，它是有效的网址

here's my logcat and the first line the url i try to connect with and it's valid url

她是我的导致错误并导致连接拒绝的代码

her is my code that cause the error and make the connection to refuse

public static String makeHttpRequest(URL url) throws IOException {
    String jsonResponse = "";
    Log.e(LOG_TAG, url.toString());

    // If the URL is null, then return early.
    if (url == null) {
        return jsonResponse;
    }

    HttpURLConnection urlConnection = null;
    InputStream inputStream = null;
    try {
        urlConnection = (HttpURLConnection) url.openConnection();

        urlConnection.setReadTimeout(10000 /* milliseconds */);
        urlConnection.setConnectTimeout(15000 /* milliseconds */);
        urlConnection.setRequestMethod("GET");
        urlConnection.connect();

        // If the request was successful (response code 200),
        // then read the input stream and parse the response.
        if (urlConnection.getResponseCode() == 200) {
            inputStream = urlConnection.getInputStream();
            jsonResponse = readFromStream(inputStream);
        } else {
            Log.e(LOG_TAG, "Error response code: " + urlConnection.getResponseCode());
        }
    } catch (IOException e) {
        Log.e(LOG_TAG, "Problem retrieving the Category JSON results.", e);
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }
        if (inputStream != null) {
            inputStream.close();
        }
    }
    return jsonResponse;
}

我已经很早就知道如何建立Http连接了，但这是第一次在本地服务器上完成

i already know how to make Http connect and done it a lot before but this the first time on local server

推荐答案

由于模拟器和笔记本电脑的本地主机不同，因此您需要执行以下操作:

Since local host for Emulator and Laptop is different, you need to do following:

1. 使用笔记本电脑的命令提示符中的 ipconfig 命令获取PC的IP地址.
2. 您应该在URL中使用 ipAddress ，而不是使用 localhost .

1. Get the IP address of your PC using: ipconfig command in your Laptop's command prompt.
2. Instead of using localhost, you should use ipAddress in your URL.

因此您的地址将变为: http://< ip地址>/lotus/getstats.php?category = ATM

So your address will become: http://<ip address>/lotus/getstats.php?category=ATM
