我跟随一个连接 Facebook 的导师,它使用以下代码成功连接到 Facebook。
代码如下 -
FB.Event.subscribe('auth.authResponseChange', function (response) {
if (response.status === 'connected') {
// the user is logged in and has authenticated your
// app, and response.authResponse supplies
// the user's ID, a valid access token, a signed
// request, and the time the access token
// and signed request each expire
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
// TODO: Handle the access token
// Do a post to the server to finish the logon
// This is a form post since we don't want to use AJAX
var form = document.createElement("form");
form.setAttribute("method", 'post');
form.setAttribute("action", 'loadMainPage.ashx');
var field = document.createElement("input");
field.setAttribute("type", "hidden");
field.setAttribute("name", 'accessToken');
field.setAttribute("value", accessToken);
form.appendChild(field);
document.body.appendChild(form);
form.submit();
} else if (response.status === 'not_authorized') {
// the user is logged in to Facebook,
// but has not authenticated your app
} else {
// the user isn't logged in to Facebook.
}
});
};
我如何请求 publish_actions 权限?
