<?php
echo "<a href='".$client->createAuthUrl()."'><button>Login with Google</button></a>";
?>
我试图在php echo中添加<a href>类，但我不能做任何我想做的样式
<?php
echo "<a href='".$client->createAuthUrl()."'><button>Login with Google</button></a>";
?>
你可以试试这样做，希望对你有帮助。
<a href="<?=createAuthUrl()?>" class="your-class-name">Login with Google"</a>
你对单引号和双引号的使用有点混乱。我还应该补充一点，标签内的按钮并不正确。我建议去掉按钮，用a标签代替。考虑到这一点，以下是选项:
常规CSS方法
echo '<a class="mylink" href="'.$client->createAuthUrl().'">Login with Google</a>';
a.mylink{
styles here
}
内联样式方法
echo '<a style="styles here" href="'.$client->createAuthUrl().'">Login with Google</a>';
从google开发的角度来看，我想问你们为什么要这样做?如果你能检测到用户没有登录，就用location头重定向用户。
<标题>index . php h1> login。$Auth = new Oauth2Authentication();
$client = $Auth->GetClient();
$client = $Auth->initializeClient($client);
我的Oauth2Authentication类的相关代码。
function initializeClient($client)
{
try {
// Set the refresh token on the client.
if (isset($_SESSION['refresh_token']) && $_SESSION['refresh_token']) {
$client->refreshToken($_SESSION['refresh_token']);
}
// If the user has already authorized this app then get an access token
// else redirect to ask the user to authorize access to Google Analytics.
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
// Set the access token on the client.
$client->setAccessToken($_SESSION['access_token']);
// Refresh the access token if it's expired.
if ($client->isAccessTokenExpired()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
$client->setAccessToken($client->getAccessToken());
$_SESSION['access_token'] = $client->getAccessToken();
}
return $client;
} else {
// We do not have access request access.
header('Location: ' . filter_var( $client->getRedirectUri(), FILTER_SANITIZE_URL));
}
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
}
