DotNetOpenAuth的Facebook登录,获取头像与基本资料

Facebook的相对比较简单,下载下来的DEMO基本就可以用了,主要列一下需要注意的地方:

1.权限设置:
是在FacebookClient里面的AuthorizationEndpoint。具体设置示例如下:

AuthorizationEndpoint = new Uri("https://graph.facebook.com/oauth/authorize?scope=email,user_birthday,read_stream,publish_stream")

 

2.获取当前登录用户的EMAIL,就是需要权限设置加上email,然后如下就可以获取用户的基本资料了:

<a href="https://graph.facebook.com/me?scope=email&fields=id,name,email,first_name,last_name,link,birthday,picture&access_token=AAABB" rel="noopener nofollow">https://graph.facebook.com/me?scope=email&fields=id,name,email,first_name,last_name,link,birthday,picture&access_token=AAABB</a>B

 

3. 获取用户头像。facebook的只要知道用户的ID或name就可以获取了。一般是获取最大的然后resize成需要的。地址如下:

http://graph.facebook.com/randy.ran.12327/picture?type=large
//or
http://graph.facebook.com/100000396765290/picture?type=large

 

4. 获取好友列表及查看好友是否已经使用了此的APP,请求地址:

https://graph.facebook.com/me/friends?fields=id,name,installed&limit=5000&offset=0

 这里注意的是 installed 参数,默认情况下是没有这个返回的。如果好友已经使用了此的APP,则这installed=true ,就是根据这个来判断有哪些好友已经用了相同的APP的。然后就可以直接关注了。

5. 使用fbUI的发送消息邀请好友

<script src="http://connect.facebook.net/en_US/all.js"></script>
<script type="text/javascript">
    FB.init({
        appId: 'app id',
        cookie: true,
        status: true,
        xfbml: true
    });
 
 
    function FacebookInviteFriends2() {
        var link_url = "http://www.facebook.com/";
        FB.ui({
            method: 'send',
            to: '100001412299717',
            name: "Join me on my ibt!",
            description: "Randy is on Pinterest, a place to discover, collect, and share inspiration. Join Pinterest to see Randy's pins and start pinning.",
            picture: "http://media-cache-ec5.pinterest.com/avatars/randyran8_1356501711_444.jpg",
            link: link_url
        }, function (response) {
            alert(response);
        });
    }
 
</script>

6. 已API方式分享:

/// <summary>
/// 分享到facebook
/// </summary>
/// <param name="token"></param>
/// <param name="name">标题</param>
/// <param name="link">点击了的连接地址</param>
/// <param name="caption">caption(一行)</param>
/// <param name="description">description</param>
/// <param name="source">显示的图片地址150x150大小,需要以http开头的哦</param>
/// <param name="message">评论内容</param>
/// <returns></returns>
public static BoolMessage Share(string token, string name, string link, string caption, string description, string source, string message)
{
    Dictionary<string, string> dic = new Dictionary<string, string>();
    dic.Add("name", name);
    dic.Add("link", link);
    dic.Add("caption", caption);
    dic.Add("description", description);
    dic.Add("source", source);
    dic.Add("privacy", "{\"value\": \"EVERYONE\"}");
    dic.Add("message", message);
    dic.Add("access_token",token);
    string url = "https://graph.facebook.com/me/feed";
    return HttpHelper.WebRequest(HttpHelper.Method.POST, url,dic);
}
