我跟着教程如何上傳圖像,但文件不出現,我不知道我在哪裏做錯了。基本上,我從手機庫中選擇一張照片併發送。上傳圖片ANDROID
下面是我的代碼:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
btnUpload = (Button) this.findViewById(R.id.btnUpload);
btnUpload.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// To open up a gallery browser
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"), 1);
}
});
btnSent = (Button) this.findViewById(R.id.btnSent);
btnSent.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
HttpUploader uploader = new HttpUploader();
try {
// String image_name =
uploader.execute(getRealPathFromURI(currImageURI)).get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
}
});
}
// To handle when an image is selected from the browser
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
// currImageURI is the global variable I’m using to hold the
// content:
currImageURI = data.getData();
path = (TextView) findViewById(R.id.path);
path.setText(getRealPathFromURI(currImageURI));
}
}
}
// Convert the image URI to the direct file system path of the image file
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
android.database.Cursor cursor = managedQuery(contentUri, proj, // Which
// columns
// to
// return
null, // WHERE clause; which rows to return (all rows)
null, // WHERE clause selection arguments (none)
null); // Order-by clause (ascending by name)
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
這裏是我的http:
for (String sdPath : path) {
Bitmap bitmapOrg = BitmapFactory.decodeFile(sdPath);
ByteArrayOutputStream bao = new ByteArrayOutputStream();
// Resize the image
double width = bitmapOrg.getWidth();
double height = bitmapOrg.getHeight();
double ratio = 400/width;
int newheight = (int) (ratio * height);
bitmapOrg = Bitmap.createScaledBitmap(bitmapOrg, 400, newheight,
true);
// Here you can define .PNG as well
bitmapOrg.compress(Bitmap.CompressFormat.JPEG, 90, bao);
byte[] ba = bao.toByteArray();
String ba1 = Base64.encodeBytes(ba);
System.out.println("uploading image now ——–" + ba1);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("image", ba1));
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://path to my server/upload.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
// print response
outPut = EntityUtils.toString(entity);
Log.i("GET RESPONSE—-", outPut);
// is = entity.getContent();
Log.e("log_tag ******", "good connection");
bitmapOrg.recycle();
} catch (Exception e) {
Log.e("log_tag ******",
"Error in http connection " + e.toString());
}
這是我的PHP代碼:
<?php
$base = $_REQUEST["image"];
if (isset($base)) {
$suffix = createRandomID();
$image_name = "img_".$suffix."_".date("Y-m-d-H-m-s").".jpg";
// base64 encoded utf-8 string
$binary = base64_decode($base);
// binary, utf-8 bytes
header("Content-Type: bitmap; charset=utf-8");
$file = fopen("../images/post_images/" . $image_name, "wb");
fwrite($file, $binary);
fclose($file);
die($image_name);
} else {
die("No POST");
}
function createRandomID() {
$chars = "abcdefghijkmnopqrstuvwxyz?";
//srand((double) microtime() * 1000000);
$i = 0;
$pass = "";
while ($i <= 5) {
$num = rand() % 33;
$tmp = substr($chars, $num, 1);
$pass = $pass . $tmp;
$i++;
}
return $pass;
}
?>
您能查看的error_log你的PHP服務器上的樣子?你在PHP方面遇到什麼錯誤? – GBD
沒有錯誤。它說好連接 –
