android使用Asynchronous Http Client如何将多文件上传到服务器var php?

    AsyncHttpClient client = new AsyncHttpClient();
        RequestParams params = new RequestParams();

    File[] file = new File[imageArrayList.size()]
    for(int i=0; i<imageArrayList.size(); i++) {
         file[i] = new File(imageArrayList.get(i));
    }

    params.put("uploadfile", file);

I don't know how to handle on php server site.

how to receive and save to my server folder?

$filePath = "uploads/"

    I am assuming you already have the file Uri so from the Android Side Use this function in AsyncTask for each file to upload multiple files

    public int uploadFile(String sourceFileUri) {
    
              String fileName = sourceFileUri;
    
              HttpURLConnection conn = null;
              DataOutputStream dos = null;  
              String lineEnd = "
    ";
              String twoHyphens = "--";
              String boundary = "*****";
              int bytesRead, bytesAvailable, bufferSize;
              byte[] buffer;
              int maxBufferSize = 1 * 1024 * 1024; 
              File sourceFile = new File(sourceFileUri); 
    
              if (!sourceFile.isFile()) {
    
    
                   Log.e("uploadFile", "Source File not exist :"
                                       +uploadFilePath + "" + uploadFileName);
    
                   runOnUiThread(new Runnable() {
                       public void run() {
                           messageText.setText("Source File not exist :"
                                   +uploadFilePath + "" + uploadFileName);
                       }
                   }); 
    
                   return 0;
    
              }
              else
              {
                   try { 
    
                         // open a URL connection to the Servlet
                       FileInputStream fileInputStream = new FileInputStream(sourceFile);
                       URL url = new URL("http://example.com/server.php");
    
                       // Open a HTTP  connection to  the URL
                       conn = (HttpURLConnection) url.openConnection(); 
                       conn.setDoInput(true); // Allow Inputs
                       conn.setDoOutput(true); // Allow Outputs
                       conn.setUseCaches(false); // Don't use a Cached Copy
                       conn.setRequestMethod("POST");
                       conn.setRequestProperty("Connection", "Keep-Alive");
                       conn.setRequestProperty("ENCTYPE", "multipart/form-data");
                       conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
                       conn.setRequestProperty("uploaded_file", fileName); 
    
                       dos = new DataOutputStream(conn.getOutputStream());
    
                       dos.writeBytes(twoHyphens + boundary + lineEnd); 
                       dos.writeBytes("Content-Disposition: form-data; name="uploaded_file";filename=""
                                                 + fileName + """ + lineEnd);
    
                       dos.writeBytes(lineEnd);
    
                       // create a buffer of  maximum size
                       bytesAvailable = fileInputStream.available(); 
    
                       bufferSize = Math.min(bytesAvailable, maxBufferSize);
                       buffer = new byte[bufferSize];
    
                       // read file and write it into form...

                       // Responses from the server (code and message)
                       serverResponseCode = conn.getResponseCode();
                       String serverResponseMessage = conn.getResponseMessage();

                                }
                            });                
                       }    
    
                       //close the streams //
                       fileInputStream.close();

                          }

                      Log.e("Upload file to server Exception", "Exception : "
                                                       + e.getMessage(), e);  
                  }
    
                  return serverResponseCode; 
    
               } 
             } 
    

    And from the Server Side server.php

    $file_path = "uploads/";
    
    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
        echo "Upload Complete";
    } else{
        echo "Upload Fail";
    }
