我正在尝试使用 OAuth2.0 在 youtube API 上进行身份验证（就像可以在文档中看到的那样）但由于某种原因我无法获得它......
这是我的连接代码：
URL url = new URL("https://accounts.google.com/o/oauth2/device/code");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
conn.setRequestProperty("Host", "accounts.google.com");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write("client_id=999999999999999.apps.googleusercontent.com&scope=https://gdata.youtube.com");
wr.flush();
// Get the response
StringBuilder sb = new StringBuilder();
InputStreamReader is = new InputStreamReader(conn.getInputStream());
BufferedReader rd = new BufferedReader(is);
String line = "";
while ((line = rd.readLine()) != null) {
sb.append(line);
}
wr.close();
rd.close();
line = sb.toString();
这是我得到的错误：
