We are experiencing the issue of Gmail atom feed with 2-legged OAuth, an error message is "401 unauthorized".
The error message is like below.
<HTML>
<HEAD>
<TITLE>Unauthorized</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Unauthorized</H1>
<H2>Error 401</H2>
</BODY>
</HTML>
Until last week, we have no problem using Gmail atom feed. From this week, we are experiencing the issue even though we have a no change regarding Gmail atom feed and oauth.
Now, this problem do not occurs on all users(50,000 accounts), but this issue is increasing more and more.
It seems that this problem is caused by Google's side.
Is there anyone who has same issue?
Source code is like below.
private GoogleOAuthParameters mOauthParameters;
private OAuthSigner mSigner;
private final String SCOPE = "https://mail.google.com/mail/feed/atom";
GoogleService service;
String result = null;
mOauthParameters = new GoogleOAuthParameters();
mSigner = new OAuthHmacSha1Signer();
mOauthParameters.setOAuthConsumerKey(CONSUMER_KEY);
mOauthParameters.setOAuthConsumerSecret(CONSUMER_SECRET);
service = new GoogleService("gmail","feed");
service.setOAuthCredentials(mOauthParameters, mSigner);
service.setConnectTimeout(timeOut);
service.setReadTimeout(timeOut * 5);
GDataRequest request = service.createFeedRequest(new URL(SCOPE +"?xoauth_requestor_id=" + email));
request.execute();
InputStream is = null;
try {
is = request.getResponseStream();
StringBuffer out = new StringBuffer();
byte[] buffer = new byte[4094];
int readSize;
while ( (readSize = is.read(buffer)) != -1) {
out.append(new String(buffer, 0, readSize));
}
result = out.toString();
} catch (Exception e) {
throw e;
} finally {
is.close();
}
I need your help.
