我正在发出好友/ ids电话:
GET /1.1/friends/ids.json?screen_name=blablabla HTTP/1.1
发出有效回复:
{"ids":[97500486,32947624,8884440,2022687,28741369,33978239,10312111,950922,7682036,21688137,7696145,15876098],"next_cursor":0,"next_cursor_str":"0","previous_cursor":0,"previous_cursor_str":"0"}
我的界面如下所示:
[OperationContract(Name = "ids.json")]
[WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate="ids.json?user_id={userId}&screen_name={screenName}")]
FriendsIdsResponse Ids(long? userId, string screenName);
[DataContract]
public class FriendsIdsResponse
{
public FriendsIdsResponse()
{
}
[DataMember(Name = "ids")]
public long[] Ids { get; set; }
[DataMember(Name = "previous_cursor")]
public int PreviousCursor { get; set; }
[DataMember(Name = "next_cursor")]
public int NextCursor { get; set; }
}
无论Ids是什么类型(long [],IList,List等),它总是返回null。如果我将它实例化为ctor中的空List,则它具有Count == 0。
更新根据要求配置WCF:
<system.serviceModel>
<client>
<endpoint contract="TA.Twitter.Service.IFriends, TA.Twitter.Interfaces"
address="https://api.twitter.com/1.1/friends/"
binding="webHttpBinding" bindingConfiguration="WebHttpBinding"
></endpoint>
</client>
<bindings>
<webHttpBinding>
<binding name="WebHttpBinding" allowCookies="true">
<security mode="Transport">
</security>
</binding>
</webHttpBinding>
</bindings>
</system.serviceModel>

不是一个完整的答案,但您是否仅限于使用WCF来调用Tweeter API? 我是WCF的忠实粉丝,但对于Twitter,已有很多.net Librairies。我知道WCF存在挑战,但我不想每次都重新发明轮子。
Tweetsharp似乎是一个流行的.net库,用于访问Twitter API。
假设您已经拥有OAuth令牌,那么使用不到10行代码就可以获得朋友。
var service = new TweetSharp.TwitterService("consumerKey", "consumerSecret");
service.AuthenticateWith("accessToken", "accessTokenSecret");
var friends = service.ListFriendIdsOf(new TweetSharp.ListFriendIdsOfOptions() { ScreenName = "blabla" });
foreach (var friend in friends)
{
Console.WriteLine("new friend :{0} ", friend);
}
不到10行,不到10分钟,似乎是一个很好的妥协
