Hilfe :(Wer weiß, wie eine POST-Anforderung für das Hochladen von YouTube-Videos über die YouTube-API in Java?Youtube POST in Java laden
Die Struktur der POST-Anforderung schreiben erforderlich here beschrieben.
Leider kann ich die Youtube-Java-Client-Bibliotheken nicht verwenden, da ich unter Android arbeite, das sie nicht unterstützt
Ich habe versucht, Code unten, aber es funktioniert nicht (ich bekomme den Fehler conn.getResponseCode() ist null)
public void videoUpload() {
HttpURLConnection conn = null;
// BufferedReader br = null;
DataOutputStream dos = null;
InputStream inStream = null;
// InputStream is = null;
// OutputStream os = null;

// String StrMessage = "";
//file path
// get filename from videoURI
String path = "file:///sdcard/";
String existingFileName = "video.3gp";
File videoFile = new File(path + existingFileName);
// String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "b93dcbA3";
String ver = "2";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1024;
// String responseFromServer = "";

conn = (HttpURLConnection) url.openConnection();
// Allow Inputs
conn.setDoInput(true);
// Allow Outputs

// Don't use a cached copy.
