Get 403: Forbidden of Google API - encoding problems in my POST?

Hi all

I have problems connecting to the Google API by MAIL by following the instructions on this page:
http://code.Google.com/APIs/accounts/docs/AuthForInstalledApps.html#ClientLogin

I've also posted on the forums of the Google API, but I'm starting to wonder if it's a problem that this forum would be able to answer. Here is the post on the Google forum:
http://www.Google.com/support/forum/p/Apps-APIs/thread?FID=1c22cb44eb5cbba600048a1fc5f25621&hl=en

Google used to accept a GET request and provide a string SID, who served as a connection key services such as Docs and Calendar. He still offers this SID to GET requests, so I know I can do the BB Simulator applications, but it no longer accepts the SID as a connection key. Now, I have to send a POST request in encoding UTF-8, including parameters as my user name and password and get an AUTH token in response.

Missions in this forum, I see that I can use a URLEncodedPostData object to encode the parameters for the WORK in UTF - 8. (I know I have to eventually get keys to use on a true signature BB, but I want to get a hello-world working on the Simulator before I pony up for them). I put the settings in this item and include it in the application, but I always get a 403: forbidden with an error message 'error = BadAuthentication' in response, as if my password is wrong. I checked the name of user and password with care, and I can do the JOB and get the AUTH token with the curvature of the line of control on this machine, there must be something about how I make the POST in the Java code.

Someone on the Google forum suggested that my settings may not have been encoded in UTF - 8, but shouldn't the 'UTF-8' parameter in the constructor URLEncodedPostData manage this coding? I also tried manually escape the '@' in my e-mail address to "% 40" because it seems that URLEncodedPostData does not encode the symbol like this @.» (My password contained no character who must escape for URL encoding.)

Here is the code I use. I use the Eclipse IDE for Blackberry OS 5 (I think that the version of the plugin for eclipse is 5.0.0_5.0.0.25) with Verizon 9630 Tour 5.0.0.591 Simulator. Any help?

private void googleSignInTest(String emailAddress, String googlePassword){

// see http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html#ClientLogin
String uri = "https://www.google.com/accounts/ClientLogin";

InputStream inputStream = null;
HttpsConnection httpsConnection = null;

try{
//create https connection, POST
httpsConnection = (HttpsConnection)Connector.open(uri);
httpsConnection.setRequestMethod(HttpsConnection.POST);

//http://supportforums.blackberry.com/t5/Java-Development/HttpConnection-set-to-POST-does-not-work/m-p...
URLEncodedPostData postData = new URLEncodedPostData("UTF-8", false);
postData.append("accountType", "GOOGLE");
postData.append("Email", emailAddress);
postData.append("Passwd", googlePassword);
postData.append("service", "cl");
postData.append("source", "my-test-app");
postData.append("Content-Type", "application/x-www-form-urlencoded");
postData.append("Content-Language", "en-US");

DataOutputStream outputStream = httpsConnection.openDataOutputStream();
outputStream.write(postData.toString().getBytes());
outputStream.flush();
outputStream.close();

//make the request and get response
int responseCode = httpsConnection.getResponseCode();
//403 Forbidden Error=BadAuthentication

//Do something with the response
...
}catch (IOException e) {
e.printStackTrace();
}

Seems that I have to set the content type in the connection, and not in the post data:

httpsConnection.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_TYPE, HttpProtocolConstants.CONTENT_TYPE_APPLICATION_X_WWW_FORM_URLENCODED);

Also, the following line is probably not just:

outputStream.write(postData.toString().getBytes());

It probably should be:

outputStream.write(postData.getBytes());

  • Get 403 Forbidden in Firefox, trying to use HELP

    Whenever I try to use the menu of HELP from LR (and other Adobe products), I get a 403 Forbidden message in Firefox my default browser.

    Is the URL which is a failure: http://community.Adobe.com/chcservices/services/redirect?u=http://help.Adobe.com & p = Lightro om_6.0 & l = en & id = AH_HOME

    If I copy and paste this URL in another browser, like IE, the redirect works and resolves at: https://helpx.Adobe.com/Lightroom/topics.html and the help page appears correctly.

    If I then copy this URL resolved in Firefox, the help page then also displays correctly.

    What is causing this problem with Firefox, and how can I solve it?

    Looks like you are running with the LR more up-to-date.

    The reason why we asked for the full version number is 6.0 (2015.0) has been released with a wrong URL in there for help pages and it has been fixed in the updated version first (?).

  • Cannot log on to Twitter. I get 403 Forbidden: the server understood the request, but refuses to fill. »

    When I try to log on to Twitter, I get the error message below.

    403 Forbidden: the server understood the request, but refuses to fill.

    Seems to emerged since I have updated to Firefox... I think so...

    You can manually connect on Twitter by removing cookies from twitter. Click on "Firefox" at the top left, and then choose 'Options '. Click on the "Privacy" tab and click on 'delete cookies '. In the list, scroll down to twitter.com and click on 'Delete the Cookies' I hope this helps. Regarding the 403 error, it is usually caused by a typing error in the address bar, or with a failure on the Twitter servers.

  • How to access a web site without getting a 403 forbidden?

    When I use a PC to access a website to any site the browser takes me to it without any problems. If I should try the same thing on my Mac Mini 2012 the same exact site gives me a 403 Forbidden message. Any browser should I use I get the same results. Why this phenomenon happens and is there a work around?

    On your Mac using Safari go to click menu bar Safari Safari > Preferences then select the Privacy tab, then click: delete all data Web site

    Quit and then restart Safari to test.

    If this does not help, you can have an extension Safari or third party plugin installed which is causing a conflict. It is easy to solve the problems.

    In the Safari menu, click Safari > Preferences , and select the tab ' Extensions '. If there are installed extensions, one at a time uninstall and exit then restart Safari to test.

    If it is not a question of extensions, try troubleshooting third-party plug-ins.

    Back to Safari > Preferences. This time select the tab Security Deselect: plug-ins Allow. Quit and restart Safari to test.

    If it makes a difference, the instructions of troubleshooting plugins here.

  • error message it says 403 forbidden, I can't get there I do not have the permission from the server

    can you help me

    Hi Stephanie,.

    To help you to propose measures to solve the problem, I would appreciate if you could answer the following questions:

    1. what web browser do you use?

    2 have you tried to use the same Web site on another computer?

    3 did you changes to the computer before the show?

    In fact this particular error message (Error 403 Forbidden) means that you are not allowed to view information about this web server in particular.

    If you use Internet Explorer and in the face of this issue then try following the steps:

    The website declined to show this webpage (HTTP 403)

    Internet Explorer is able to connect to the Web site, but Internet Explorer does not have permission to view the Web page. This can happen for various reasons; Here are some of the most common:

    ·         The site administrator has to give you permission to view the page or the web server does not accept applications for page. If there is a site you should have Internet access, contact the site administrator.

    ·         The Web page that you are trying to view is generated by a program, such as contains a shopping cart or search engine and the folder on the server, the program is not correctly configured by the site administrator.

    ·         You typed a basic web address (for example, www.example.com), but the site doesn't have a default (e.g. index.htm or default.html) Web page. In addition, the site does not list directories, which allows you to view files in a web folder.

    You can also view the article mentioned below for more information:

    I recommend no doubt create a subzone for Movi, you can also control the bandwidth also. I have never save anything to the default subfield on Highway and off the record for security purposes. Movi clients enter their own subfield

    NES as well as sub-areas for other specific things.

    For security reasons, I don't like is not verification of the credentials on the highway, especially if you have an ISDN gateway or maybe control has a route on the PSTN. Fraud free of charge is not sweet.

    I always sent SSO via local vs LDAP authentication. It becomes difficult when you are unable to join the fast track to the area but still want to authenticate and verify the credentials. The trick is that you must create a local user on the highway, and then create the same identical user name and the password in active directory. Then in MSD, get these credentials by using the model configuration for the version / MOVI device.
