上传 服务器 端php 代码如下 ： ? php $ target_path = ./tmp/ ;// 接收文件目录 $ target_path = $ target_path .( $ _files [ 'file' ][ 'name' ] ); $ target_path = iconv ( utf-8 , gb2312 , $ target_path ); if ( move_uploaded_file ( $ _files [ 'f
上传
服务器端php代码如下 ：
php $target_path = ./tmp/;//接收文件目录 $target_path = $target_path.($_files['file']['name']); $target_path = iconv(utf-8,gb2312, $target_path); if(move_uploaded_file($_files['file']['tmp_name'], $target_path)) { echo the file .( $_files['file']['name']). has been uploaded.; }else{ echo there was an error uploading the file, please try again! error code: .$_files['file']['error']; }?>
监控进度实现首先定义监听器接口，如下所示：
//进度监听器接口public interface progresslistener { public void transferred(long transferedbytes);}
实现监控进度的关键部分就在于记录已传输字节数，所以我们需重载filteroutputstream，重写其中的关键方法，实现进度监听的功能，如下所示，本例中首先重载的是httpentitywrapper，顾名思义，就是将需发送的httpentity打包，以便计算总字节数，代码如下：
// progressouthttpentity：输出流(outputstream)时记录已发送字节数public class progressouthttpentity extends httpentitywrapper { private final progresslistener listener; public progressouthttpentity(final httpentity entity, final progresslistener listener) { super(entity); this.listener = listener; } public static class countingoutputstream extends filteroutputstream { private final progresslistener listener; private long transferred; countingoutputstream(final outputstream out, final progresslistener listener) { super(out); this.listener = listener; this.transferred = 0; } @override public void write(final byte[] b, final int off, final int len) throws ioexception { // no, double-counting, as super.write(byte[], int, int) // delegates to write(int). // super.write(b, off, len); out.write(b, off, len); this.transferred += len; this.listener.transferred(this.transferred); } @override public void write(final int b) throws ioexception { out.write(b); this.transferred++; this.listener.transferred(this.transferred); } } @override public void writeto(final outputstream out) throws ioexception { this.wrappedentity.writeto(out instanceof countingoutputstream ? out : new countingoutputstream(out, this.listener)); }}
最后就是使用上述实现的类和httpclient进行上传并显示进度的功能，非常简单，代码如下，使用asynctask异步上传。
public class fileuploadasynctask extends asynctaskfile, integer, string> { private string url = http://192.168.83.213/receive_file.php; private context context; private progressdialog pd; private long totalsize; public fileuploadasynctask(context context) { this.context = context; } @override protected void onpreexecute() { pd = new progressdialog(context); pd.setprogressstyle(progressdialog.style_horizontal); pd.setmessage(上传中....); pd.setcancelable(false); pd.show(); } @override protected string doinbackground(file... params) { // 保存需上传文件信息 multipartentitybuilder entitys = multipartentitybuilder.create(); entitys.setmode(httpmultipartmode.browser_compatible); entitys.setcharset(charset.forname(http.utf_8)); file file = params[0]; entitys.addpart(file, new filebody(file)); httpentity httpentity = entitys.build(); totalsize = httpentity.getcontentlength(); progressouthttpentity progresshttpentity = new progressouthttpentity( httpentity, new progresslistener() { @override public void transferred(long transferedbytes) { publishprogress((int) (100 * transferedbytes / totalsize)); } }); return uploadfile(url, progresshttpentity); } @override protected void onprogressupdate(integer... progress) { pd.setprogress((int) (progress[0])); } @override protected void onpostexecute(string result) { pd.dismiss(); toast.maketext(context, result, toast.length_short).show(); } //上传文件到服务器 //服务器地址 //文件 public static string uploadfile(string url, progressouthttpentity entity) { httpclient httpclient = new defaulthttpclient(); httpclient.getparams().setparameter( coreprotocolpnames.protocol_version, httpversion.http_1_1); // 设置连接超时时间 httpclient.getparams().setparameter( coreconnectionpnames.connection_timeout, 5000); httppost httppost = new httppost(url); httppost.setentity(entity); try { httpresponse httpresponse = httpclient.execute(httppost); if (httpresponse.getstatusline().getstatuscode() == httpstatus.sc_ok) { return 文件上传成功; } } catch (clientprotocolexception e) { e.printstacktrace(); } catch (connecttimeoutexception e) { e.printstacktrace(); } catch (exception e) { e.printstacktrace(); } finally { if (httpclient != null && httpclient.getconnectionmanager() != null) { httpclient.getconnectionmanager().shutdown(); } } return 文件上传失败; }}
