以下是我使用 InAppBrowser 进行 Facebook 身份验证的方法。由于您只是想从 url 中获取一个值,因此它应该以相同的方式工作:
var fb = {
id: '...'
,secret: '...'
,namespace: '...'
,redirect: '...'
,display: 'touch'
,scope: ['publish_actions']
,windowRef: null
,code: null
,onLoadEvent: function(event){
var url = event.url;
console.log(url);
//once we've been redirected to this domain, fb's job is done
if (/my.domain.com/.test(url)){
if (/code=/.test(url)){
//auth done
var code = url.match(/code=([^\&]+)/)
if (code) code = code[1];
window.fb.code = code;
window.fb.windowRef.close();
}else if (/error_description=/.test(url)){
//login unsuccessful
var error = url.match(/error_description=([^\&]+)/);
if (error) error = error[1].replace(/[^A-Z0-9 ]/gi, " ");
console.error("facebook login failed: " + error);
window.fb.code = null;
window.fb.windowRef.close();
}
}
}
};
var authUrl = "https://graph.facebook.com/oauth/authorize?"
+ "client_id=" + fb.id
+ "&redirect_uri=" + encodeURI(fb.redirect)
+ "&display=" + fb.display
+ "&scope=" + fb.scope.join('%2C');
fb.windowRef = window.open(authUrl, '_blank', loginPopupOptions);
//no reason we can't use the same function twice...
fb.windowRef.addEventListener('loadstart', fb.onLoadEvent);
fb.windowRef.addEventListener('loadstop', fb.onLoadEvent);
我试图只从我们的结构中提取相关部分,所以希望这样有意义......
