背景
网上很多上传到java服务器上的,找了好久,找到了上传到php的了,思路跟我当初想的差不多,就是POST过去。废话不多说,直接上图看代码。
PHP代码
PHP代码
-
- $target_path = "./upload/" ; //接收文件目录
- $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!" . $_FILES [ 'uploadedfile' ][ 'error' ];
- }
- ?>
Android代码
上传的主要代码:
Java代码
- private void uploadFile(String uploadUrl)
- {
- String end = "\r\n" ;
- String twoHyphens = "--" ;
- String boundary = "******" ;
- try
- {
- URL url = new URL(uploadUrl);
- HttpURLConnection httpURLConnection = (HttpURLConnection) url
- .openConnection(); //http连接
- // 设置每次传输的流大小,可以有效防止手机因为内存不足崩溃
-
- httpURLConnection.setChunkedStreamingMode( 128 * 1024 ); // 128K
- // 允许输入输出流
- httpURLConnection.setDoInput( true );
- httpURLConnection.setDoOutput( true );
- httpURLConnection.setUseCaches( false );
- // 使用POST方法
- httpURLConnection.setRequestMethod( "POST" );
- httpURLConnection.setRequestProperty( "Connection" , "Keep-Alive" ); //保持一直连接
- httpURLConnection.setRequestProperty( "Charset" , "UTF-8" ); //编码
- httpURLConnection.setRequestProperty( "Content-Type" ,
- "multipart/form-data;boundary=" + boundary); //POST传递过去的编码
-
- DataOutputStream dos = new DataOutputStream(
- httpURLConnection.getOutputStream()); //输出流
- dos.writeBytes(twoHyphens + boundary + end);
- dos.writeBytes( "Content-Disposition: form-data; name=\"uploadedfile\"; filename=\""
- + srcPath.substring(srcPath.lastIndexOf( "/" ) + 1 )
- + "\""
- + end);
- dos.writeBytes(end);
-
- FileInputStream fis = new FileInputStream(srcPath); //文件输入流,写入到内存中
- byte [] buffer = new byte [ 8192 ]; // 8k
- int count = 0 ;
- // 读取文件
- while ((count = fis.read(buffer)) != - 1 )
- {
- dos.write(buffer, 0 , count);
- }
- fis.close();
-
- dos.writeBytes(end);
- dos.writeBytes(twoHyphens + boundary + twoHyphens + end);
- dos.flush();
-
- InputStream is = httpURLConnection.getInputStream(); //http输入,即得到返回的结果
- InputStreamReader isr = new InputStreamReader(is, "utf-8" );
- BufferedReader br = new BufferedReader(isr);
- String result = br.readLine();
-
- Toast.makeText( this , result, Toast.LENGTH_LONG).show(); //将结果输出
- dos.close();
- is.close();
-
- } catch (Exception e)
- {
- e.printStackTrace();
- setTitle(e.getMessage());
- }
- }
因为安卓4.0之后耗时间的操作要求都在非UI线程中操作,即将前面的AsyncTask拿来用了吧~
AsyncTask传送门: http://www.cnblogs.com/yydcdut/p/3707960.html
在这个类中,将上传的操作放在doInBackground当中,可以有ProgressDialog显示上传了多少:
Java代码
- // Read file
- bytesRead = fileInputStream.read(buffer, 0 , bufferSize);
-
- while (bytesRead > 0 ) {
- outputStream.write(buffer, 0 , bufferSize);
- length += bufferSize;
- progress = ( int ) ((length * 100 ) / totalSize);
- publishProgress(progress);
-
- bytesAvailable = fileInputStream.available();
- bufferSize = Math.min(bytesAvailable, maxBufferSize);
- bytesRead = fileInputStream.read(buffer, 0 , bufferSize);
- }
- outputStream.writeBytes(lineEnd);
- outputStream.writeBytes(twoHyphens + boundary + twoHyphens
- + lineEnd);
- publishProgress( 100 );
还有就是,注意权限哟:
