这是我的logcat和我尝试连接的网址的第一行以及它的有效网址
她是我的代码导致错误并使连接拒绝
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;
}
我已经知道如何进行Http连接并且之前已经完成了很多但是这是第一次在本地服务器上

由于Emulator和Laptop的本地主机不同,您需要执行以下操作:
ipconfig
命令获取PC的IP地址。localhost
,而不是使用ipAddress
。 所以你的地址将成为:
http://<ip address>/lotus/getstats.php?category=ATM
