最近试验android拍照上传的功能，基本顺利。

试验条件，

客户端，android2.2

服务器端，linux, nginx php 5.2

android 代码如下：

PHP代码如下：

///如果有上传文件则接收

if($_FILES){

$target_path = $target_path . basename( $_FILES['file1']['name']);

try{if(move_uploaded_file($_FILES['file1']['tmp_name'], $target_path)) {

echo "The file ".  basename( $_FILES['file1']['name']). " has been uploaded";

}

}catch( Exception $e ) {

echo $e->getMessage();   }

}

else  ///如果不是上传文件则列出图片

{

file_list(".");

}

function file_list($path){

$im_type=array('bmp','jpg','jpeg','png','gif');

if ($handle = opendir($path)) {

while (false !== ($file = readdir($handle)))

{

if ($file != "." && $file != "..") {

if (is_dir($path."/".$file))

{

file_list($path."/".$file);

}

else

{

if(strpos($file,'.png',1)||strpos($file,'.jpg',1)||strpos($file,'.ico',1)||strpos($file,'.gif',1))

{

echo ' ';

}

}

}

}

}

}

?>

Android 代码：

package com.app.model;

import java.io.DataOutputStream;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.InputStream;

import java.net.HttpURLConnection;

import java.net.URL;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.widget.Toast;

public class SubmitPhoto extends Activity

{

/* 变量声明

* newName：上传后在服务器上的文件名称

* uploadFile：要上传的文件路径

* actionUrl：服务器对应的程序路径 */

private String newName="";

private String uploadFile="";

private String actionUrl="http://dev.feiren.com/uploads/android/upload.php";

@Override

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

Intent intent = this.getIntent();

Bundle bundle = intent.getExtras();

newName = bundle.getString("fileName");

uploadFile=newName;

try {

String ok=post(actionUrl,newName);

Toast.makeText(this, "OK!",Toast.LENGTH_LONG).show();

finish();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

/* 上传文件到Server的方法*/

/**

* @param actionUrl

* @param params

* @param files

* @return

* @throws IOException

*/

public static String post(String actionUrl,String FileName) throws IOException {

String BOUNDARY = java.util.UUID.randomUUID().toString();

String PREFIX = "--" , LINEND = "\r\n";

String MULTIPART_FROM_DATA = "multipart/form-data";

String CHARSET = "UTF-8";

URL uri = new URL(actionUrl);

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

conn.setReadTimeout(5 * 1000); // 缓存的最长时间

conn.setDoInput(true);// 允许输入

conn.setDoOutput(true);// 允许输出

conn.setUseCaches(false); // 不允许使用缓存

conn.setRequestMethod("POST");

conn.setRequestProperty("connection", "keep-alive");

conn.setRequestProperty("Charsert", "UTF-8");

conn.setRequestProperty("Content-Type", MULTIPART_FROM_DATA + ";boundary=" + BOUNDARY);

DataOutputStream outStream = new DataOutputStream(conn.getOutputStream());

// 发送文件数据

if(FileName!=""){

StringBuilder sb1 = new StringBuilder();

sb1.append(PREFIX);

sb1.append(BOUNDARY);

sb1.append(LINEND);

sb1.append("Content-Disposition: form-data; name=\"file1\"; filename=\""+FileName+"\""+LINEND);

sb1.append("Content-Type: application/octet-stream; charset="+CHARSET+LINEND);

sb1.append(LINEND);

outStream.write(sb1.toString().getBytes());

InputStream is = new FileInputStream(FileName);

byte[] buffer = new byte[1024];

int len = 0;

while ((len = is.read(buffer)) != -1) {

outStream.write(buffer, 0, len);

}

is.close();

outStream.write(LINEND.getBytes());

}

//请求结束标志

byte[] end_data = (PREFIX + BOUNDARY + PREFIX + LINEND).getBytes();

outStream.write(end_data);

outStream.flush();

//得到响应码

int res = conn.getResponseCode();

InputStream in = null;

if (res == 200) {

in = conn.getInputStream();

int ch;

StringBuilder sb2 = new StringBuilder();

while ((ch = in.read()) != -1) {

sb2.append((char) ch);

}

}

return in == null ? null : in.toString();

}

}

以上代码已经试验成功。这个代码可以实现很多有意思的应用，比如你在户外拍照，刚拍下来，你所有的朋友马上都可以在你的微薄或者空间里看到。
