Php 如何使用post方法上传带有参数的图像

我按照这个上传图像。我正在成功发送图像

String urlFormation = WebConstants.UPLOAD_IMAGE;
Log.i(TAG, "urlFormation: ======"+urlFormation);
URL url = new URL(urlFormation);

// Open a HTTP  connection to  the URL
conn = (HttpURLConnection) url.openConnection(); 
conn.setRequestProperty("user_id", userID); 
conn.setRequestProperty("release_id", releaseID); 

但是如何用相同的请求发送一些参数

String urlFormation = WebConstants.UPLOAD_IMAGE;
Log.i(TAG, "urlFormation: ======"+urlFormation);
URL url = new URL(urlFormation);

// Open a HTTP  connection to  the URL
conn = (HttpURLConnection) url.openConnection(); 
conn.setRequestProperty("user_id", userID); 
conn.setRequestProperty("release_id", releaseID); 

这些参数是我想要发送的

String urlFormation = WebConstants.UPLOAD_IMAGE;
Log.i(TAG, "urlFormation: ======"+urlFormation);
URL url = new URL(urlFormation);

// Open a HTTP  connection to  the URL
conn = (HttpURLConnection) url.openConnection(); 
conn.setRequestProperty("user_id", userID); 
conn.setRequestProperty("release_id", releaseID);

请帮帮我。谢谢

简单的方法是使用GET

String urlFormation = WebConstants.UPLOAD_IMAGE;
Log.i(TAG, "urlFormation: ======"+urlFormation);
URL url = new URL(urlFormation);

// Open a HTTP  connection to  the URL
conn = (HttpURLConnection) url.openConnection(); 
conn.setRequestProperty("user_id", userID); 
conn.setRequestProperty("release_id", releaseID); 

如果需要POST，可以将数据附加到请求正文中

String urlFormation = WebConstants.UPLOAD_IMAGE;
Log.i(TAG, "urlFormation: ======"+urlFormation);
URL url = new URL(urlFormation);

// Open a HTTP  connection to  the URL
conn = (HttpURLConnection) url.openConnection(); 
conn.setRequestProperty("user_id", userID); 
conn.setRequestProperty("release_id", releaseID);
