这是我在使用FB api时遇到的最奇怪的问题。也许我只是用他们的API太多了n00b,但是这里有。
我正在使用我网站的登录按钮。单击后,将向用户显示FB弹出窗口,告诉他们有关我的应用程序的基本信息(基本详细信息,活动用户数和请求的权限)
这一切都很好,花花公子。如果用户接受该应用程序,则将重新加载该页面,并且将从应用程序请求的信息将插入到数据库中并创建会话。

每次刷新页面时都会在DB中插入一行。没有创建任何会话。更奇怪的是,插入数据库中fb_id列的facebook id属于一个帐户,该帐户属于FB用于测试提交审批的开放图形操作的测试帐户。我知道,因为在深入了解数据库之后,我在DB中看到了一行属于FB开放图操作测试人员。 ID为“2147483647”。这显然不是打印出$ user_profile数组时打印出来的ID。此外,在第一次重新加载页面之后,甚至不应该发生插入查询,因为返回的rowCount设置为1.如果用户是第一次用户,则应该执行插入查询。沙箱模式未启用。我想可能与它有关。但是,事实并非如此。
在一个不相关的说明中,FB的api在执行
时是否存在错误$facebook->api("/me");
这似乎不起作用。
$facebook->api("/".$user);
似乎工作得很好。
可以找到实例[{3}}

Facebook user_id
可能超出支持的整数长度。在iPhone SDK
上发现了一个长ID,例如。 '10000328862128237
'。我怀疑这也是你的问题,因为我得到完全相同的数字'2147483647
