我正在创建一个应用程序，我必须捕获视频并将其上传到服务器，如藤蔓应用程序。
工作流程： 一个按钮将用于“上传您自己的视频”
当用户点击按钮时，它将打开相机并开始录制视频。当用户停止录制时，视频将保存在SD卡上的文件夹中，并自动上传到服务器。
我有两个测试项目。一个捕获视频并保存它。其他将视频或任何文件上传到服务器上。 在上传视频项目中，我预先指定了一个特定的文件。
我的问题是如何合并这两个项目以满足我的需求。
我发布的源代码如下：
文件上传的源代码：
// messageText.setText("Uploading file path :- '/mnt/sdcard/"+uploadFileName+"'");
messageText.setText("Uploading file path :- '/storage/emulated/0/"+uploadFileName+"'");
/************* Php script path ****************/
upLoadServerUri = "MY_SERVER_LINK";
uploadButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog = ProgressDialog.show(MainActivity.this, "", "Uploading file...", true);
new Thread(new Runnable() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("uploading started.....");
}
});
uploadFile(uploadFilePath + "" + uploadFileName);
}
}).start();
}
});
}
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() {
messageText.setText("Source File not exist :"
+uploadFilePath + "" + uploadFileName);
}
});
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.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();

}
// 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.v("uploadFile", "HTTP Response is : "
+ serverResponseMessage + ": " + serverResponseCode);
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {

+" MY_SERVER_LINK"
+uploadFileName;
messageText.setText(msg);

在您的视频捕获代码中，您已调用
startActivityForResult(intent,CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);
合并它们，将onActivityResult添加到同一个文件
@Override
protected void onActivityResult(int requestCode, final int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
dialog =ProgressDialog.show(Activity.this, "", "loading...",false,true);
if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
new Thread(new Runnable() {
@Override
public void run() {
//call code in upload
runOnUiThread(new Runnable() {
@Override
public void run() {
dialog.dismiss();
}
});
}
}).start();

只需将代码从第一个项目复制到第二个项目，即可将您的视频或任何文件上传到服务器上，并将uri作为文件传递给上载函数。您也可以使用翻新2或looj在服务器上上传文件。
