OAuth issue in importing google contacts

Tag : php , By : Frank Bradley
Date : March 29 2020, 07:55 AM
Does that help Looks like you're forgetting to pass the code to the authenticate method. Here's the documentation and implementation of the authenticate method in Google_Client.php:
 * Attempt to exchange a code for an valid authentication token.
 * If $crossClient is set to true, the request body will not include
 * the request_uri argument
 * Helper wrapped around the OAuth 2.0 implementation.
 * @param $code string code from accounts.google.com
 * @param $crossClient boolean, whether this is a cross-client authentication
 * @return string token
public function authenticate($code, $crossClient = false)
  $this->authenticated = true;
  return $this->getAuth()->authenticate($code, $crossClient);
if (isset($_GET['code'])) {
    $client->authenticate($_GET['code']); // <-- Add code parameter here
    $_SESSION['token'] = $client->getAccessToken();
    header('Location: ' . $redirect_uri);

Any of those help You can use this method to get all the contacts in .vcf file. It return the same output that you get using AddressBook.framework.
- (void)getContacts {
    NSMutableArray *contactsArray=[[NSMutableArray alloc] init];
    CNContactStore *store = [[CNContactStore alloc] init];
    [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (!granted) {
            dispatch_async(dispatch_get_main_queue(), ^{
        NSMutableArray *contacts = [NSMutableArray array];

        NSError *fetchError;

        CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[[CNContactVCardSerialization descriptorForRequiredKeys], [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]]];

        BOOL success = [store enumerateContactsWithFetchRequest:request error:&fetchError usingBlock:^(CNContact *contact, BOOL *stop) {
            [contacts addObject:contact];
        if (!success) {
            NSLog(@"error = %@", fetchError);

        // you can now do something with the list of contacts, for example, to show the names

        CNContactFormatter *formatter = [[CNContactFormatter alloc] init];

        for (CNContact *contact in contacts) {

            [contactsArray addObject:contact];
            // NSString *string = [formatter stringFromContact:contact];

            //NSLog(@"contact = %@", string);

        //NSError *error;
        NSData *vcardString =[CNContactVCardSerialization dataWithContacts:contactsArray error:&error];

        NSString* vcardStr = [[NSString alloc] initWithData:vcardString encoding:NSUTF8StringEncoding];
        NSLog(@"vcardStr = %@",vcardStr);

        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *folderPath = [paths objectAtIndex:0];
        NSString *filePath = [folderPath stringByAppendingPathComponent:@"Contacts.vcf"];
        [vcardStr writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:nil];

Error while importing google contacts libraries?

Tag : python , By : Matt Croydon
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further You got the error because you installed atom as a separate dependency. gdata included atom in packages but not in requirements.
I will try to explain with an example. Activate a new virtualenv, install gdata:
pip install gdata==2.0.18
import atom.data
import gdata.data
import gdata.contacts.client
import gdata.contacts.data
