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
-
<?php
-
$target_path = "./upload/";
-
$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();
-
-
-
httpURLConnection.setChunkedStreamingMode(128 * 1024);
-
-
httpURLConnection.setDoInput(true);
-
httpURLConnection.setDoOutput(true);
-
httpURLConnection.setUseCaches(false);
-
-
httpURLConnection.setRequestMethod("POST");
-
httpURLConnection.setRequestProperty("Connection", "Keep-Alive");
-
httpURLConnection.setRequestProperty("Charset", "UTF-8");
-
httpURLConnection.setRequestProperty("Content-Type",
-
"multipart/form-data;boundary=" + boundary);
-
-
DataOutputStream dos = new DataOutputStream(
-
httpURLConnection.getOutputStream());
-
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);
-
byte[] buffer = new byte[8192];
-
int count = 0;
-
-
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();
-
InputStreamReader isr = new InputStreamReader(is, "utf-8");
-
BufferedReader br = new BufferedReader(isr);
-
String result = br.readLine();
-
-
Toast.makeText(this, result, Toast.LENGTH_LONG).show();
-
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
-
-
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:
XML/HTML代码
-
<uses-permission android:name="android.permission.INTERNET" />
