如何从JavaScript SDK中的FB.login方法获取访问令牌
我需要从Javascript SDK中的FB.login方法获取访问令牌。 我的login代码是
FB.login(function(response) { if (response.session) { if (response.perms) { } else { // user is logged in, but did not grant any permissions alert("No Permission.."); } } else { // user is not logged in alert("Please login to facebook"); } }, {perms:'read_stream,publish_stream,offline_access'});
有没有办法获得访问令牌？ 我能够使用PHP获取访问令牌。
提前致谢….
您可以使用FB.getAuthResponse()['accessToken']获取访问令牌：
FB.login(function(response) { if (response.authResponse) { var access_token = FB.getAuthResponse()['accessToken']; console.log('Access Token = '+ access_token); FB.api('/me', function(response) { console.log('Good to see you, ' + response.name + '.'); }); } else { console.log('User cancelled login or did not fully authorize.'); } }, {scope: ''});
编辑：更新为使用Oauth 2.0，自2011年12月以来需要。现在使用FB.getAuthResponse(); 如果您使用的是没有控制台的浏览器（我正在与您通话，请使用Internet Explorer），请确保将console.log行注释掉或使用以下日志安全脚本：
if (typeof(console) == "undefined") { console = {}; } if (typeof(console.log) == "undefined") { console.log = function() { return 0; } }
response.session.access_token在我的代码中不起作用。 但是这个工作： response.authResponse.accessToken
FB.login(function(response) { alert(response.authResponse.accessToken); }, {perms:'read_stream,publish_stream,offline_access'});
如果您已经连接 ，只需在javascript控制台中input：
FB.getAuthResponse()['accessToken']
https://developers.facebook.com/docs/facebook-login/login-flow-for-web/
{ status: 'connected', authResponse: { accessToken: '...', expiresIn:'...', signedRequest:'...', userID:'...' } } FB.login(function(response) { if (response.authResponse) { // The person logged into your app } else { // The person cancelled the login dialog } });
response.session不起作用，因为response.authResponse是oauth迁移后访问响应内容的新方法。
