我正在尝试将 img 从 android 手机上传到 php 服务器。
但是当它上传它的数据丢失（文件存在但有0字节）
我不知道问题出在 php 端还是 android 端。
这是我使用上传的代码
PHP：
<?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……';
?>
爪哇：
private void httpPostFileUpload(String fpath){
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;
String pathToOurFile = fpath;
Log.v("file path",fpath.toString());
String urlServer = "http://leojg.alwaysdata.net/tests/androidConnect/upload_image.php";
//String urlServer = "http://65.182.110.63/public/handle_upload.php";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
String fname = "";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
try
{
File f = new File(pathToOurFile);
fname = f.getName();
FileInputStream fileInputStream = new FileInputStream(f);
URL url = new URL(urlServer);
connection = (HttpURLConnection) url.openConnection();
// Allow Inputs & Outputs
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
// Enable POST method
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
outputStream = new DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
outputStream.writeBytes(lineEnd);
Log.v("ouput stream",outputStream.toString());
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// Read file
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
int serverResponseCode = connection.getResponseCode();
String serverResponseMessage = connection.getResponseMessage();
Log.d("amanda", "upload async finished, server response : " + serverResponseMessage);
fileInputStream.close();
fileInputStream = null;
outputStream.flush();
outputStream.close();
outputStream = null;
f= null;
parent.invokeJs("pictureUploadEnded('" + fname + "')");
//this.delete(fpath);
}
catch (Exception ex)
{
Log.d("amanda", "exception uploading image : " + ex.getMessage());
}
}
在这里你可以看到 img 的存储位置http://leojg.alwaysdata.net/tests/androidConnect/
解决方案：
<?php
$target_path = "./";
$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!";
}
?>
