Hi all,
Recently, I want to develop a simple application to upload
videos to YouTube. But after reading the
tutorial of YouTube Data API.
(http://code.google.com/intl/zh-TW/apis/youtube/2.0/
developers_guide_protocol_direct_uploading.html)
I don't know how to fix the problem I encounter now.
The following is my code and after executing it, the HTTP
response code is 400 (Bad Request) and
the error message is "Incomplete Multipart Body".
Please give me some suggestions and directions.
Thank you very much.
[MyCode]
public void upload(String token, String clientID, String developerKey,
File file)
{
String youtubeUrl = "http://uploads.gdata.youtube.com/feeds/api/
users/default/uploads";
URL url = null;
try
{
url = new URL(youtubeUrl);
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setUseCaches(false);
conn.setRequestProperty("Host",
"uploads.gdata.youtube.com");
conn.setRequestProperty("Authorization", "GoogleLogin auth=\"" +
token + "\"");
conn.setRequestProperty("GData-Version", "2");
conn.setRequestProperty("X-GData-Client", clientID);
conn.setRequestProperty("X-GData-Key", "key=" + developerKey);
conn.setRequestProperty("Slug", file.getName());
conn.setRequestProperty("Content-Type", "multipart/related;
boundary=\"" + boundary + "\"");
conn.setRequestProperty("Content-Length", getLength());
conn.setRequestProperty("Connection", "close");
DataOutputStream writer = new
DataOutputStream(conn.getOutputStream
());
writer.write(("\r\n--" + boundary + "\r\n").getBytes());
writer.write("Content-Type: application/atom+xml;
charset=UTF-8\r\n
\r\n".getBytes());
writer.write(getXml().getBytes("UTF-8"));
