下面是runtime exeception
我在尝试将图像上传到服务器时得到的。
我正在尝试使用我的本地服务器(WAMP)上传图像,而我的 android 代码是
Bitmap bitmap = BitmapFactory.decodeFile("/sdcard/Sunset.jpg");
// Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.background1);
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://192.168.1.49/android/upload_image.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
String the_string_response = convertResponseToString(response);
Toast.makeText(uploadimage.this, "Response " + the_string_response, Toast.LENGTH_LONG).show();
}catch(Exception e){
Toast.makeText(uploadimage.this, "ERROR " + e.getMessage(), Toast.LENGTH_LONG).show();
System.out.println("Error 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(uploadimage.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 string buffer to string
Toast.makeText(uploadimage.this, "Result : " + res, Toast.LENGTH_LONG).show();
//System.out.println("Response => " + EntityUtils.toString(response.getEntity()));
}
return res;
}
}
这是我从互联网上获得的 php 代码。
<?php
$base=$_REQUEST['image'];
$binary=base64_decode($base);
header('Content-Type: bitmap; charset=utf-8');
$file = fopen('uploaded_image.jpg', 'wb');
fwrite($file, $binary);
fclose($file);
echo 'Image upload complete!!, Please check your php file directory……';
?>
任何人都可以帮助我解决我的问题。提前致谢
