我正在玩GAE和Android試圖獲得一個爲web服務製作的應用程序。我正在完成從Android的AccountManager獲取身份驗證令牌的步驟，根據需要獲取Cookie，然後將該cookie附加到GAE python應用程序處理的GET請求。出於某種原因，GAE應用程序似乎無法識別cookie或其他內容。很抱歉，對於這個巨大的帖子，我想我會盡可能多地在代碼中幫助解釋。GAE無法識別Cookie？
我在GAE中有這個基本類來測試用戶是否被識別。
class TestUser(webapp.RequestHandler):
def get(self):
if users.get_current_user():
self.response.out.write(users.get_current_user().nickname())
else:
self.response.out.write('no user')
application = webapp.WSGIApplication([
('/', MainPage),
('/testuser', TestUser)
], debug=True)
def main():
run_wsgi_app(application)
if __name__ == '__main__':
main()
從瀏覽器，這很好。我看到用戶。在Android上執行時，我得到「沒有用戶」。
這裏有一堆的Android代碼：
的onCreate：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
cookieLength = (TextView)findViewById(R.id.cookielength);
cookie = "";
AccountManager manager = AccountManager.get(getApplicationContext());
Account[] accounts = manager.getAccountsByType("com.google");
new GetAuthTokenTask().execute(accounts);
}
獲得身份驗證令牌，而無效，並再次得到它，以避免過期的令牌：
private class GetAuthTokenTask extends AsyncTask<Account, Object, String> {
@Override
protected String doInBackground(Account... accounts) {
AccountManager manager = AccountManager.get(getApplicationContext());
Account account = accounts[0];
String token = this.buildToken(manager, account);
Log.d(TAG, "First token: "+token);
manager.invalidateAuthToken(account.type, token);
return this.buildToken(manager, account);
}
private String buildToken(AccountManager manager, Account account) {
try {
AccountManagerFuture<Bundle> future = manager.getAuthToken (account, "ah", false, null, null);
Bundle bundle = future.getResult();
return bundle.getString(AccountManager.KEY_AUTHTOKEN);
} catch (OperationCanceledException e) {
Log.w(TAG, e.getMessage());
} catch (AuthenticatorException e) {
Log.w(TAG, e.getMessage());
} catch (IOException e) {
Log.w(TAG, e.getMessage());
}
return null;
}
protected void onPostExecute(String authToken) {
Log.d(TAG, "Second token: "+authToken);
getCookie(authToken);
}
}
獲取用戶的cookie，存儲在全局cookie字符串中。
private void getCookie(final String authToken) {
new Thread(new Runnable() {
public void run() {
String href = "https://someawesomeapp.appspot.com/_ah/login?continue=http://localhost/&auth="+authToken;
Log.d(TAG, "href: "+href);
DefaultHttpClient httpclient = new DefaultHttpClient();
final HttpParams params = new BasicHttpParams();
HttpClientParams.setRedirecting(params, false);
httpclient.setParams(params);
HttpGet httpget = new HttpGet(href);
try {
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
entity.consumeContent();
}
List<Cookie> cookies = httpclient.getCookieStore().getCookies();
Log.d(TAG, "Cookies");
if (cookies.isEmpty()) {
Log.d(TAG, "None");
} else {
for (int i = 0; i < cookies.size(); i++) {
Log.d(TAG, "- " + cookies.get(i).toString());
Cookie c = cookies.get(i);
Log.d(TAG, "cookie.getname(): "+c.getName());
if (c.getName().contentEquals("SACSID")) {
Log.d(TAG, "Found SACSID cookie");
cookie = c.getValue();
Log.d(TAG, "cookie now set to: "+cookie);
}
}
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
}
現在我們已經存儲cookie的時候，在用戶界面按下測試按鈕的用戶，這是執行：
公共無效爲testUser（查看視圖）{ Log.d（TAG， 「爲testUser（）」 ）;
String href = "http://someawesomeapp.appspot.com/testuser";
DefaultHttpClient httpclient = new DefaultHttpClient();
final HttpParams params = new BasicHttpParams();
HttpClientParams.setRedirecting(params, false);
httpclient.setParams(params);
HttpGet httpget = new HttpGet(href);
httpget.setHeader("Cookie", cookie);
try {
HttpResponse response = httpclient.execute(httpget);
StatusLine status = response.getStatusLine();
if (status.getStatusCode() != 200) {
throw new IOException("Invalid response from server: " + status.toString());
}
HttpEntity entity = response.getEntity();
if (entity != null) {
//entity.consumeContent();
InputStream inputStream = entity.getContent();
ByteArrayOutputStream content = new ByteArrayOutputStream();
// Read response into a buffered stream
int readBytes = 0;
byte[] sBuffer = new byte[512];
while ((readBytes = inputStream.read(sBuffer)) != -1) {
content.write(sBuffer, 0, readBytes);
}
String dataAsString = new String(content.toByteArray());
Log.d(TAG, "response: "+dataAsString);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
下面是Wireshark的連接的一嗅：
GET /testuser HTTP/1.1

這裏的反應是 「沒有用戶」 從GAE。有關如何讓GAE接受cookie並以cookie作爲用戶的任何想法？
27秒後，我想我找到了一個問題。這是來自瀏覽器的嗅探，我沒有那個ACSID =部分。
Cookie: ACSID=AJKiYcFeUHZUP56a
感謝您的幫助！
有狀態
編輯：我弄明白了。我需要等待一段時間來回答我自己的問題，但沒有足夠的聲望。基本上，因爲我使用SSL獲取cookie，所以cookie需要以SACSID而非ACSID作爲前綴，並且testuser url也需要爲https，因爲這是我們使用的cookie。
