Android:使用 php 在服务器上上传图像
始终在服务器上上传 0KB 的图片 test.jpg！
Always upload image test.jpg with 0KB on the server!
图片如下:
所以你可以看到我在服务器上得到了什么.
So you can see what am i getting on the server.
我将不胜感激任何帮助或建议，我希望我能解决问题..
I would appreciate any help or suggesting and i hope i will solve the problem..
安卓代码:
public class Main extends Activity {
InputStream inputStream;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream); //compress to which format you want.
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeBytes(byte_arr);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("image",image_str));
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://server/uploader2.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
String the_string_response = convertResponseToString(response);
Toast.makeText(this, "Response " + the_string_response, Toast.LENGTH_LONG).show();
}catch(Exception e){
Toast.makeText(this, "ERROR " + e.getMessage(), Toast.LENGTH_LONG).show();
System.out.println("Error in http connection "+e.toString());
}
}
public String convertResponseToString(HttpResponse response) throws IllegalStateException, IOException{
String res = "";
StringBuffer buffer = new StringBuffer();
inputStream = response.getEntity().getContent();
int contentLength = (int) response.getEntity().getContentLength(); //getting content length…..
Toast.makeText(this, "contentLength : " + contentLength, Toast.LENGTH_LONG).show();
if (contentLength < 0){
}
else{
byte[] data = new byte[512];
int len = 0;
try
{
while (-1 != (len = inputStream.read(data)) )
{
buffer.append(new String(data, 0, len)); //converting to string and appending to stringbuffer…..
}
}
catch (IOException e)
{
e.printStackTrace();
}
try
{
inputStream.close(); // closing the stream…..
}
catch (IOException e)
{
e.printStackTrace();
}
res = buffer.toString(); // converting stringbuffer to string…..
Toast.makeText(this, "Result : " + res, Toast.LENGTH_LONG).show();
//System.out.println("Response => " + EntityUtils.toString(response.getEntity()));
}
return res;
}}
和php代码...(uploader2.php)
and php code... (uploader2.php)
<?php
$base=$_REQUEST['image'];
$binary=base64_decode($base);
header('Content-Type: image/jpg; charset=utf-8');
$file = fopen('test.jpg', 'wb');
fwrite($file, $binary);
fclose($file);
echo 'Image upload complete!!, Please check your php file directory……';
echo "<img src=test.jpg>";
?>
有什么问题?
