Question

如果用户尚未登录Facebook，我想创建一个可以提示登录的页面，然后检查用户是否是某个组的成员。如果没有，请提供一个按钮，单击该按钮将向该用户发送群组邀请。

在发送群组邀请的最后一步之前，我可以做所有事情。我想知道它是否有可能。该小组是一个普通的开放小组，而不是文档所说的仍处于测试阶段的应用小组。

我console.log响应，看到单击按钮时出现以下错误。

Object {error: Object}
error: Object
code: 3
message: "(#3) "
type: "OAuthException"

错误代码和错误消息根本没有帮助...

这是我到目前为止的完整代码

身份验证流程运行正常，问题出在sendInvite（）函数中，我愿意接受建议。

哦......，如果有人想要这个代码的css文件。（这不是问题的关键）

body {
    text-align: center; 
    font-family:Comic Sans MS;
    text-shadow: 0 1px 0 #222222;

    margin-top:20px;
    font-weight: bold;
    text-shadow: 0 3px 0 #222222;
}

#login
{
    width: 413px;
    height: 70px;
    background-image:url('../img/login.png');
    margin-left:auto;
    margin-right:auto;
    display:none;
    cursor:pointer;
}

#logout
{
    width: 413px;
    height: 70px;
    background-image:url('../img/logout.png');
    margin-left:auto;
    margin-right:auto;
    display:none;
    cursor:pointer;
}

#sendInvite
{
    background-color: cyan;
    cursor: pointer;
    border: black thin solid;
    margin-top:10px;
    max-width: 200px;
    padding: 5px;
    margin-left:auto;
    margin-right:auto;
}

#sendInvite:hover
{
    background-color: skyblue;
    color : green;
}
