Google ClientLogin認証

Question

使用して認証を作成してみます clientlogin

URL url = new URL("https://www.google.com/accounts/ClientLogin");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");

connection.setRequestProperty("Email", "testonly%2Ein%2E2011%40gmail%2Ecom");
connection.setRequestProperty("Passwd", "mypass");
connection.setRequestProperty("accountType", "HOSTED");
connection.setRequestProperty("service", "apps");
connection.connect();

しかし、私は得ます Error=BadAuthentication. 。コードを修正するにはどうすればよいですか？

適切なものを設定する必要があります application/x-www-form-urlencoded Content-type そして、使用します OutputStream ポストボディを書くために。

//Open the Connection
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);
urlConnection.setRequestProperty("Content-Type",
                                 "application/x-www-form-urlencoded");

// Form the POST parameters
StringBuilder content = new StringBuilder();
content.append("Email=").append(URLEncoder.encode(youremail, "UTF-8"));
content.append("&Passwd=").append(URLEncoder.encode(yourpassword, "UTF-8"));
content.append("&service=").append(URLEncoder.encode(yourapp, "UTF-8"));
OutputStream outputStream = urlConnection.getOutputStream();
outputStream.write(content.toString().getBytes("UTF-8"));
outputStream.close();

// Retrieve the output
int responseCode = urlConnection.getResponseCode();
InputStream inputStream;
if (responseCode == HttpURLConnection.HTTP_OK) {
  inputStream = urlConnection.getInputStream();
} else {
  inputStream = urlConnection.getErrorStream();
}
