你好我试图在用户用facebook按钮点击登录时设置一个POST ..这是因为在我制作的代码中,如果你已经注销,但是在Facebook中插入,那么你会在网站中再次被盗...所以,如果你注销,你永远不会注销..
为了避免这种情况我试图设置POST,设置经典条件
if ( isset ($_POST['fbconnect']))
我只需添加一个隐藏的输入并发送该表单usinf fb:login-button
这是我尝试过的......没有运气。
<form name="fbconnect" method="post">
<input type="hidden" name="fbconnect" value="fbconnect" />
<div id="fb-root"></div>
<fb:login-button scope='email,user_birthday'></fb:login-button></form>
<?php
}
?>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : <?=YOUR_APP_ID?>,
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
FB.Event.subscribe('auth.login', function(response) {
// ------------------------------------------------------
// This is the callback if everything is ok
$(this).parents('form').submit();
});
};
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
我也尝试用表单名称替换$(this).parents('form').submit();
表单,但它可以正常工作
我也试过这个
<script>
window.fbAsyncInit = function() {
FB.init({
appId : <?=YOUR_APP_ID?>,
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
FB.Event.subscribe('auth.login', function(response) {
// ------------------------------------------------------
// This is the callback if everything is ok
var url = "index.php";
var params = "fbconnect=fbconnect";
http.open("POST", url, true);
//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");
http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
}
http.send(params);
});
};
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
答案 0 :(得分:1)
更好的做法是在用户注销时使用重定向,而不是POST,即:
HTML:
<a onclick="FB.logout">Logout</a>
和Javascript:
FB.Event.subscribe('auth.authResponseChange', function(response) {
if (response.status == "connected") {
// log in login
}
else if (response.status != "connected") {
// logout logic, i.e
// location.href = "/sessions/logout";
alert("User has disconnected")
location.href = "/index.php?fbconnect=fbconnect"
}
});
如果你坚持发帖,你可以使用jQuery来简化事情:
FB.Event.subscribe('auth.login', function(response) {
$.post("index.php", {fbconnect: fbconnect}, function(data, response) {
alert(data);
});
});
