服务器端（Servlet的）code在Android的上传图片 [英] Server side(Servlet) code for upload image in android
本文介绍了服务器端（Servlet的）code在Android的上传图片的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
如何保存使用Java在我的服务器的特定位置如C Android设备上传的图片：\\ Program Files文件\\ Tomcat的7.0 \\图片。
这里是我的客户端code
公共静态无效uploadPictureToServer（字符串i_file）抛出ClientProtocolException，IOException异常{
位图bitmapOrg = BitmapFactory.de codeFILE（i_file）; ByteArrayOutputStream宝=新ByteArrayOutputStream（）; bitmapOrg.com preSS（Bitmap.Com pressFormat.JPEG，90，包）; 字节[] BA = bao.toByteArray（）; 字符串BA1 = Base64.en code（BA）; ArrayList的＆LT;＆的NameValuePair GT; namevaluepairs中新= ArrayList的＆LT;＆的NameValuePair GT;（）; nameValuePairs.add（新BasicNameValuePair（形象，BA1））; 尝试{ HttpClient的HttpClient的=新DefaultHttpClient（）; HttpPost httppost =新 HttpPost（Constant.uploadImage）; httppost.setEntity（新UrlEn codedFormEntity（namevaluepairs中））; HTT presponse响应= httpclient.execute（httppost）; HttpEntity实体= response.getEntity（）; 是= entity.getContent（）; }赶上（例外五）{ Log.e（log_tag，在HTTP连接错误+ e.toString（））; }
解决方案
工作code对我来说：
doFileUpload功能：
私人无效doFileUpload（）{
HttpURLConnection的康恩= NULL;
DataOutputStream类DOS = NULL;
DataInputStream以inStream中= NULL;
字符串exsistingFileName =/sdcard/six.3gp;
//这是这个地方，你做错了什么。
字符串lineEnd =\\ r \\ n;
串twoHyphens = - ;
字符串边界=*****;
INT读取动作，方bytesAvailable，缓冲区大小;
字节[]缓冲区;
INT MAXBUFFERSIZE = 1 * 1024 * 1024;
字符串urlString =http://192.168.1.5/upload.php;
尝试
{
Log.e（MediaPlayer的，内部第二种方法）;
的FileInputStream的FileInputStream =新的FileInputStream（新文件（exsistingFileName））;
网址URL =新的URL（urlString）;
康恩=（HttpURLConnection类）url.openConnection（）;
conn.setDoInput（真）;
//允许输出
conn.setDoOutput（真）;
//不要使用缓存副本。
conn.setUseCaches（假）;
//使用POST方法。
conn.setRequestMethod（POST）;
conn.setRequestProperty（连接，保持活动）;
conn.setRequestProperty（内容类型，的multipart / form-data的;边界=+边界）;
DOS =新的DataOutputStream类（conn.getOutputStream（））;
dos.writeBytes（twoHyphens +边界+ lineEnd）;
dos.writeBytes（内容处置：表格数据;名称= \\UploadedFile的\\;文件名= \\+ exsistingFileName +\\+ lineEnd）;
dos.writeBytes（lineEnd）;
Log.e（MediaPlayer的，头信息）;
参考bytesAvailable = fileInputStream.available（）;
BUFFERSIZE = Math.min（方bytesAvailable，MAXBUFFERSIZE）;
缓冲区=新的字节[缓冲区大小]
读取动作= fileInputStream.read（缓冲液，0，缓冲区大小）;
而（读取动作大于0）
{
dos.write（缓冲液，0，缓冲区大小）;
参考bytesAvailable = fileInputStream.available（）;
BUFFERSIZE = Math.min（方bytesAvailable，MAXBUFFERSIZE）;
读取动作= fileInputStream.read（缓冲液，0，缓冲区大小）;
}
dos.writeBytes（lineEnd）;
dos.writeBytes（twoHyphens +边界+ twoHyphens + lineEnd）;
在的BufferedReader =新的BufferedReader（新的InputStreamReader（conn.getInputStream（）））;
串inputLine;
而（（inputLine = in.readLine（））！= NULL）
tv.append（inputLine）;
//关闭流
Log.e（MediaPlayer的，文件写入）;
fileInputStream.close（）;
dos.flush（）;
dos.close（）;
}
赶上（MalformedURLException的前）
{
Log.e（MediaPlayer的，错误：+ ex.getMessage（），除息）;
}
赶上（IOException异常IOE）
{
Log.e（MediaPlayer的，错误：+ ioe.getMessage（），IOE）;
} // ------------------读取服务器响应
尝试{
inStream中=新DataInputStream所（conn.getInputStream（））;
字符串str;
而（（海峡= inStream.readLine（））！= NULL）
{
Log.e（MediaPlayer的，服务器响应+ STR）;
}
/ *而（（海峡= inStream.readLine（））！= NULL）{ } * /
inStream.close（）;
}
赶上（IOException异常ioex）{
Log.e（MediaPlayer的，错误：+ ioex.getMessage（），ioex）;
}
}
upload.php的
＆LT; PHPmove_uploaded_file（$ _ FILES ['UploadedFile的'] ['tmp_name的值']，./upload/\".$_FILES[\"uploadedfile\"][\"name]）;mysql_connect（localhost的根，）;
mysql_select_db（聊天）;
如果（使用isset（$ _ REQUEST ['味精']））
{
$ a = $ _REQUEST ['味精'];
$ SQL =INSERT INTO上传（图）VALUES（'$ A'）;
的mysql_query（$的SQL）;
}
？＆GT;
how to save the image uploaded from a android device using java in my server to a specific location like C:\Program Files\Tomcat 7.0\Images. here is my client side code
public static void uploadPictureToServer(String i_file) throws ClientProtocolException,IOException {
Bitmap bitmapOrg = BitmapFactory.decodeFile(i_file);
ByteArrayOutputStream bao = new ByteArrayOutputStream();
bitmapOrg.compress(Bitmap.CompressFormat.JPEG, 90, bao);
byte [] ba = bao.toByteArray();
String ba1=Base64.encode(ba);
ArrayList<NameValuePair> nameValuePairs = new
ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("image",ba1));
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new
HttpPost(Constant.uploadImage);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
}
解决方案
Working Code for me :
doFileUpload Function :
private void doFileUpload(){
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String exsistingFileName = "/sdcard/six.3gp";
// Is this the place are you doing something wrong.
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
String urlString = "http://192.168.1.5/upload.php";
try
{
Log.e("MediaPlayer","Inside second Method");
FileInputStream fileInputStream = new FileInputStream(new File(exsistingFileName) );
URL url = new URL(urlString);
conn = (HttpURLConnection) url.openConnection();
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=\"" + exsistingFileName +"\"" + lineEnd);
dos.writeBytes(lineEnd);
Log.e("MediaPlayer","Headers are written");
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
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);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
tv.append(inputLine);
// close streams
Log.e("MediaPlayer","File is written");
fileInputStream.close();
dos.flush();
dos.close();
}
catch (MalformedURLException ex)
{
Log.e("MediaPlayer", "error: " + ex.getMessage(), ex);
}
catch (IOException ioe)
{
Log.e("MediaPlayer", "error: " + ioe.getMessage(), ioe);
}
//------------------ read the SERVER RESPONSE
try {
inStream = new DataInputStream ( conn.getInputStream() );
String str;
while (( str = inStream.readLine()) != null)
{
Log.e("MediaPlayer","Server Response"+str);
}
/*while((str = inStream.readLine()) !=null ){
}*/
inStream.close();
}
catch (IOException ioex){
Log.e("MediaPlayer", "error: " + ioex.getMessage(), ioex);
}
}
upload.php
<?php
move_uploaded_file($_FILES['uploadedfile']['tmp_name'], "./upload/".$_FILES["uploadedfile"]["name"]);
mysql_connect("localhost","root","");
mysql_select_db("chat");
if(isset($_REQUEST['msg']))
{
$a = $_REQUEST['msg'];
$sql = "INSERT INTO upload(image)VALUES('$a')";
mysql_query($sql);
}
?>
