将图像从android上传到cakephp服务器

Question

目前我正在为web服务构建应用程序版本，所以我试图通过应用程序将图像从我的android手机上传到我的cakephp web服务器。

// Android的代码

HttpURLConnection conn = null; 
     DataOutputStream dos = null; 
     DataInputStream inStream = null; 
     String existingFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/New Folder/rsz_passportphoto.jpg"; 
     String lineEnd = "\r\n"; 
     String twoHyphens = "--"; 
     String boundary = "*****"; 
     int bytesRead, bytesAvailable, bufferSize; 
     byte[] buffer; 
     int maxBufferSize = 1*1024*1024; 
     String responseFromServer = ""; 
     String urlString = "http://msm.icas.edu.sg/FANS/FANSweb/app/controllers/pagesext_controller.php"; 
     try 
     { 
     //------------------ CLIENT REQUEST 
     FileInputStream fileInputStream = new FileInputStream(new File(existingFileName)); 
     // open a URL connection to the Servlet 
     URL url = new URL(urlString); 
     // Open a HTTP connection to the URL 
     conn = (HttpURLConnection) url.openConnection(); 
     System.out.println("Connected"); 
     // Allow Inputs 
     conn.setDoInput(true); 
     // Allow Outputs 
     conn.setDoOutput(true); 
     // Don't use a cached copy. 
     conn.setUseCaches(false); 
     // Use a post method. 
     conn.setRequestMethod("POST"); 
     conn.setRequestProperty("Connection", "Keep-Alive"); 
     conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); 
     dos = new DataOutputStream(conn.getOutputStream()); 
     dos.writeBytes(twoHyphens + boundary + lineEnd); 
     dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + existingFileName + "\"" + 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... 
     bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
     while (bytesRead > 0) 
     { 
      dos.write(buffer, 0, bufferSize); 
      bytesAvailable = fileInputStream.available(); 
      bufferSize = Math.min(bytesAvailable, maxBufferSize); 
      bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
     } 
     // send multipart form data necesssary after file data... 
     dos.writeBytes(lineEnd); 
     dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
     // close streams 
     Log.e("Debug","File is written"); 
     fileInputStream.close(); 
     Log.e("Debug","file input close"); 
     dos.flush(); 
     Log.e("Debug","flushed"); 
     dos.close(); 
     Log.e("Debug","closed"); 
     } 
     catch (MalformedURLException ex) 
     { 
      Log.e("Debug", "error 1 : " + ex.getMessage(), ex); 
     } 
     catch (IOException ioe) 
     { 
      Log.e("Debug", "error 2: " + ioe.getMessage(), ioe); 
     } 
     //------------------ read the SERVER RESPONSE 
     try { 
       inStream = new DataInputStream (conn.getInputStream()); 
       String str; 

       while ((str = inStream.readLine()) != null) 
       { 
        Log.e("Debug","Server Response "+str); 
       } 
       inStream.close(); 

     } 
     catch (IOException ioex){ 
      Log.e("Debug", "error: " + ioex.getMessage(), ioex); 
     } 
     } 

它永远是 9月7日至26日：13：34.112：E /调试（810）：错误：http://msm.icas.edu.sg/FANS/FANSweb/app/controllers/pagesext_controller.php 9月7日至26日：13：34.112：电子/调试（810）：java.io.FileNotFoundException：http://msm.icas.edu.sg/FANS/FANSweb/app/controllers/pagesext_controller.php

或试试这个

// PHP代码

<?php 

$target_path = "uploads/"; 

$target_path = $target_path . basename($_FILES['uploadedfile']['name']); 

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { 
echo "The file ". basename($_FILES['uploadedfile']['name']). 
" has been uploaded"; 
} else{ 
echo "There was an error uploading the file, please try again!"; 
} 

?> 

/// Android的代码放在这里

public class HttpFileUploader implements Runnable{

} 


void doStart(FileInputStream stream){ 
fileInputStream = stream; 
thirdTry(); 
} 

FileInputStream fileInputStream = null; 
void thirdTry(){ 
String exsistingFileName = "asdf.png"; 

String lineEnd = "\r\n"; 
String twoHyphens = "--"; 
String boundary = "*****"; 
String Tag="3rd"; 
try 
{ 
//------------------ CLIENT REQUEST 

Log.e(Tag,"Starting to bad things"); 
// Open a HTTP connection to the URL 

HttpURLConnection conn = (HttpURLConnection) connectURL.openConnection(); 

// Allow Inputs 
conn.setDoInput(true); 

// Allow Outputs 
conn.setDoOutput(true); 

// Don't use a cached copy.

// Use a post method. 
conn.setRequestMethod("POST");

Log.e(Tag,"Headers are written"); 

// create a buffer of maximum size 

int bytesAvailable = fileInputStream.available(); 
int maxBufferSize = 1024; 
int bufferSize = Math.min(bytesAvailable, maxBufferSize); 
byte[] buffer = new byte[bufferSize]; 

// read file and write it into form...

// close streams 
Log.e(Tag,"File is written");

// retrieve the response from server 
int ch; 

StringBuffer b =new StringBuffer(); 
while((ch = is.read()) != -1){ 
b.append((char)ch); 
} 
String s=b.toString(); 
Log.i("Response",s); 
dos.close(); 


} 
catch (MalformedURLException ex) 
{ 
Log.e(Tag, "error: " + ex.getMessage(), ex); 
} 

catch (IOException ioe) 
{ 
Log.e(Tag, "error: " + ioe.getMessage(), ioe); 
} 
} 

} 

Many of the headers included in the above file is not required, i was trying and failing :). 

Now to upload file here is the java code from my activity class 


public void uploadFile(){ 


try { 
FileInputStream fis =this.openFileInput(NAME_OF_FILE); 
HttpFileUploader htfu = new HttpFileUploader("http://11.0.6.23/test2.php","noparamshere", NAME_OF_FILE); 
htfu.doStart(fis); 
} catch (FileNotFoundException e) { 
// TODO Auto-generated catch block 
e.printStackTrace(); 
} 
}
