PHP使用？id =（图像路径）显示图像

Question

我有一个子域https://i.luckvintage.net。我使用该网站通过ShareX轻松地将图像发送给我的客户。当我按“打印屏幕”按钮时，文件会自动上传到该网站。带有图片的网址示例如下：

我想收集有关使用第三方网站查看图像等人数的统计信息。为此，我需要将一些代码嵌入文件中。如何使PHP以URL形式https://i.luckvintage.net/image.php?id=chrome_1ZVoGRTlVv.png显示图像？

非常感谢。

您可以使用package com.example.asjuh.automatedsystem; import android.app.Activity; import android.content.Context; import android.content.SharedPreferences; import android.os.AsyncTask; import android.os.Bundle; import android.view.View; import android.widget.EditText; import android.widget.Switch; import android.widget.Toast; import android.widget.ToggleButton; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.ProtocolException; import java.net.URL; public class MainActivity extends Activity implements View.OnClickListener { public final static String PREF_IP = "PREF_IP_ADDRESS"; public final static String PREF_PORT = "PREF_PORT_NUMBER"; // declare buttons and text inputs private ToggleButton buttonPin2; private Switch IOTbutton; private EditText editTextIPAddress, editTextPortNumber; // shared preferences objects used to save the IP address and port so that the user doesn't have to // type them next time he/she opens the app. SharedPreferences.Editor editor; SharedPreferences sharedPreferences; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); sharedPreferences = getSharedPreferences("HTTP_HELPER_PREFS", Context.MODE_PRIVATE); editor = sharedPreferences.edit(); // assign buttons IOTbutton = (Switch)findViewById(R.id.switch1); buttonPin2 = (ToggleButton)findViewById(R.id.toggleButton2); // assign text inputs editTextIPAddress = (EditText)findViewById(R.id.editTextIPAddress); editTextPortNumber = (EditText)findViewById(R.id.editTextPortNumber); // set button listener (this class) buttonPin2.setOnClickListener(this); IOTbutton.setOnClickListener(this); // get the IP address and port number from the last time the user used the app, // put an empty string "" is this is the first time. editTextIPAddress.setText(sharedPreferences.getString(PREF_IP,"")); editTextPortNumber.setText(sharedPreferences.getString(PREF_PORT,"")); } @Override public void onClick(View view) { // get the pin number String parameterValue = ""; String parameter=""; // get the ip address String ipAddress = editTextIPAddress.getText().toString().trim(); // get the port number String portNumber = editTextPortNumber.getText().toString().trim(); // save the IP address and port for the next time the app is used editor.putString(PREF_IP, ipAddress); // set the ip address value to save editor.putString(PREF_PORT, portNumber); // set the port number to save editor.commit(); // save the IP and PORT // get the pin number from the button that was clicked if(view.getId()==IOTbutton.getId()){ parameter="IOT"; if(IOTbutton.getText().equals("ON")){ parameterValue="1"; } else{ parameterValue="0"; } } else if(view.getId() == buttonPin2.getId()) { parameter="pin"; if(buttonPin2.getText().equals("ON")){ parameterValue="1"; } else{ parameterValue="0"; } } if(ipAddress.length()>0 && portNumber.length()>0) { HttpGetRequest htp= new HttpGetRequest(this); htp.execute("http://"+ipAddress+":"+portNumber+"/?"+parameter+"="+parameterValue); } } public class HttpGetRequest extends AsyncTask<String,Void,String>{ public static final String REQUEST_METHOD = "GET"; public static final int READ_TIMEOUT = 30000; public static final int CONNECTION_TIMEOUT = 30000; private Context mContext; String result; public HttpGetRequest(Context context) { //Relevant Context should be provided to newly created components (whether application context or activity context) //getApplicationContext() - Returns the context for all activities running in application mContext = context.getApplicationContext(); } @Override protected String doInBackground(String... params) { String stringUrl = params[0]; try { URL myUrl = new URL(stringUrl); //Create a connection HttpURLConnection connection =(HttpURLConnection) myUrl.openConnection(); //Set methods and timeouts connection.setRequestMethod(REQUEST_METHOD); connection.setReadTimeout(READ_TIMEOUT); connection.setConnectTimeout(CONNECTION_TIMEOUT); connection.setDoInput(true); connection.setDoOutput(true); //Connect to our url connection.connect(); //Create a new InputStreamReader InputStreamReader streamReader = new InputStreamReader(connection.getInputStream()); //Create a new buffered reader and String Builder BufferedReader reader = new BufferedReader(streamReader); StringBuilder stringBuilder = new StringBuilder(); //Check if the line we are reading is not null String inputLine; while((inputLine = reader.readLine()) != null){ stringBuilder.append(inputLine); } //Close our InputStream and Buffered reader reader.close(); streamReader.close(); //Set our result equal to our stringBuilder result = stringBuilder.toString(); } catch (ProtocolException e) { e.printStackTrace(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return result; } @Override protected void onPostExecute(String r) { //Print the response code as toast popup Toast.makeText(mContext, "Response code: " + r, Toast.LENGTH_SHORT).show(); } @Override protected void onPreExecute() { Toast.makeText(mContext, "Going for the network call..", Toast.LENGTH_SHORT).show(); } } } 并将img设置为src
