在我的android代码中，我试图将.3gp文件上传到XAMPP服务器。我重复使用了以下代码来上传文件：
public int uploadFile(String sourceFileUri) {
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "'r'n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"
+uploadFilePath + "" + uploadFileName);
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "Source File not exist :"
+uploadFilePath + "" + uploadFileName, Toast.LENGTH_LONG).show();
}
});
return 0;
} else {
try {
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL(upLoadServerUri);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name='"uploaded_file'";filename='""
+ fileName + "'"" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Log.i("uploadFile", "HTTP Response is : "
+ serverResponseMessage + ": " + serverResponseCode);
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
public void run() {
String msg = "File Upload Completed.'n'n See uploaded file here : 'n'n"
+" http://www.androidexample.com/media/uploads/" +uploadFileName;
Toast.makeText(getApplicationContext(), "File Upload Complete.",
Toast.LENGTH_SHORT).show();
}
});
}
//close the streams //
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
dialog.dismiss();
ex.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "MalformedURLException",
Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
dialog.dismiss();
e.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "Got Exception : see logcat ",
Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server Exception", "Exception : "
+ e.getMessage(), e);
}
dialog.dismiss();
return serverResponseCode;
} // End else block
}
具有以下参数：
String upLoadServerUri = "http://"+iPAddress+"/patient/upload.php";
/********** File Path *************/
final String uploadFilePath = Environment.getExternalStorageDirectory().getPath()+"/Patient_Records/";
final String uploadFileName = "record.3gp";
下面是我的upload.php文件：
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
我在upload.php的同一目录中有一个目录uploads，更具体地说：
PHP文件upload.php完整路径为：C:'xampp'htdocs'patient'upload.php上传目录完整路径为：C:'xampp'htdocs'patient'uploads
android活动没有抱怨。在运行时，我收到消息"File Upload Complete."，好像一切都很顺利。但是，我在upload目录中找不到上传的文件。怎么了？
我建议您使用HttpClient类以多部分的形式发送数据。这里提到了一个简单的解决方案从Android手机到服务器的视频文件传输(https://stackoverflow.com/a/17673687/2482430)这对你的很有用
代码
public void uploadVideo(Context context, String videoPath) {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(context.getString(R.string.url_service_fbpost));
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
if(!videoPath.isEmpty()){
FileBody filebodyVideo = new FileBody(new File(videoPath));
reqEntity.addPart("uploaded", filebodyVideo);
}
postRequest.setEntity(reqEntity);
HttpResponse response = httpClient.execute(postRequest);
BufferedReader reader = new BufferedReader(new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
Log.e("Response: ", s.toString());
return true;
} catch (Exception e) {
Log.e(e.getClass().getName(), e.getMessage());
return false;
}
}
