我只是使用TortoiseSVN将项目从家用笔记本电脑复制到办公室PC。但是该项目在我的办公室PC上运行不正常。
在这里，我的代码被卡在这里（我认为）。
public class SyncDatabase extends AsyncTask<String, Void, String> {
Handler mHandler = null;
public void setHandler(Handler handler) {
mHandler = handler;
}
private static final String TAG = "SyncDatabase";
Context mContext;
AlertDialog mAlertDialog;
public SyncDatabase(Context context) {
mContext = context;
}
String post_url = "http://192.168.56.1/php_poedi/progress_business/admin/process/location-Backup.php";
@Override
protected String doInBackground(String... params) {
try{
String txtLatitude = params[0];
String txtLongitude = params[1];
String editUserID = params[2];
String editEmailPHP = params[3];
String tempRadio = params[4];
String editDate = params[5];
String nationality = params[6];
URL url = new URL(post_url);
Log.d(TAG, "checkpost_url: "+ post_url);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);
httpURLConnection.setDoInput(true);
OutputStream outputStream = httpURLConnection.getOutputStream();
Log.d(TAG, "txtLatitude " + txtLatitude + "txtLongitude "+ txtLongitude);
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
String post_data = URLEncoder.encode("latitude", "UTF-8")+"="+URLEncoder.encode(txtLatitude,"UTF-8")
+"&"+URLEncoder.encode("longitude", "UTF-8")+"="+URLEncoder.encode(txtLongitude, "UTF-8")
+"&"+URLEncoder.encode("username", "UTF-8")+"="+URLEncoder.encode(editUserID, "UTF-8")
+"&"+URLEncoder.encode("email", "UTF-8")+"="+URLEncoder.encode(editEmailPHP, "UTF-8")
+"&"+URLEncoder.encode("gender", "UTF-8")+"="+URLEncoder.encode(tempRadio, "UTF-8")
+"&"+URLEncoder.encode("birthday", "UTF-8")+"="+URLEncoder.encode(editDate, "UTF-8")
+"&"+URLEncoder.encode("nationality", "UTF-8")+"="+URLEncoder.encode(nationality, "UTF-8");
bufferedWriter.write(post_data);
bufferedWriter.close();
outputStream.close();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "iso-8859-1"));
String result = "";
String line = "";
while ((line = bufferedReader.readLine()) != null) {
result += line;
}
Log.d(TAG, "result: "+ result);
bufferedReader.close();
inputStream.close();
httpURLConnection.disconnect();
return result;
} catch (MalformedURLException e){
e.printStackTrace();
} catch (IOException e){
e.printStackTrace();
}
return null;
}
@Override
protected void onPreExecute() {
mAlertDialog = new AlertDialog.Builder(mContext).create();
mAlertDialog.setTitle("Login Status");
}
@Override
protected void onPostExecute(String s) {
mAlertDialog.setMessage(s);
Log.d(TAG, "onPostExecute: "+ s);
if(mHandler!=null){
Message message = new Message();
message.obj = s;
mHandler.sendMessage(message);
Log.d(TAG, "Message " + message);
}
}
}
这是我的错误。

家用笔记本电脑或办公室PC上的项目都没有进行编辑。 我认为问题出在Android Studio设置中，但在哪一部分呢？我没有任何线索！
这是我的network_security_config.xml
<network-security-config>
<base-config cleartextTrafficPermitted="true">
<trust-anchors>
<certificates src="system" />
</trust-anchors>
</base-config>
</network-security-config>
还有AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.example.register">
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

答案 0 :(得分：0)
据我从您的logcat所看到的，您正在尝试连接到本地服务器以进行某些位置备份，因此您正在向具有以下IP地址{{1 }}。
在家里，您可能正在运行一个服务器应用程序，该服务器应用程序只能在本地网络中通信。您需要为服务器计算机提供一个公共IP地址，以访问服务器在本地网络（例如您的办公室）之外提供的API。
从Logcat中可以看到，您正在尝试连接到以下主机。
192.168.56.1您的办公室网络无法访问此地址，因为此IP地址是您家中一台计算机的IP地址（即本地IP地址）。因此，调用此API时找不到资源，我的猜测是，当您从服务器未获得任何信息时，您将不处理响应。
因此，我有两个建议。
http://192.168.56.1/php_poedi/progress_business/admin/process/locationBackup.php
。您可能还会考虑，将您的家用计算机设置为具有公共IP地址，但是，我认为这将需要很长时间才能由您自己执行。 192.168.56.1块来处理这种情况。如果无法解析服务器的响应，则可以在catch块中获取该响应，并生成try/catch或错误消息。 希望有帮助！
