在Windows Phone上请求access_token时，Instagram API返回错误

我一直在尝试将Instagram API集成到我的应用程序中，但我仍然坚持使用身份验证 . 当我刚刚使用隐式流版本时，我让它完全正常工作，它给了我access_token作为URI片段的一部分 . 但是，现在我改为服务器端流程，我在用户登录后收到代码 . 然后我将这些代码发布到访问令牌URL，然后会给我access_token以及有关的某些信息 . 用户，例如他们的用户名和 Profiles 图片链接 .

我正在使用InstaSharp库，修改源代码 .

HttpClient client = new HttpClient { BaseAddress = new Uri(config.OAuthUri + "access_token/", UriKind.Absolute) };
        var request = new HttpRequestMessage(HttpMethod.Post, client.BaseAddress);

        request.AddParameter("client_secret", config.ClientSecret);
        request.AddParameter("client_id", config.ClientId);
        request.AddParameter("grant_type", "authorization_code");
        request.AddParameter("redirect_uri", config.RedirectUri);
        request.AddParameter("code", code);

        return client.ExecuteAsync<OAuthResponse>(request);

创建请求后，其格式如下：{方法：POST，RequestUri：'https://api.instagram.com/oauth/access_token/?client_secret= ＆client_id = ＆grant_type = authorization_code＆redirect_uri = http://instagram.com＆code = ', Version: 1.1, Content: , Headers: { }} (I inserted the space between the redirect_uri and code because it wouldn' t让我发布问题否则）

地址中的所有内容都显示正常，但我总是在重新调整的json文件中收到错误：

“{”code“：400，”error_type“：”OAuthException“，”error_message“：”您必须提供client_id“}”

我不知道造成这个错误的原因 . 任何帮助是极大的赞赏！谢谢！埃利奥特

    您使用的是最新版本的InstaSharp吗？叉吧here . 您可以在那里查看README.md，尽管's a bit outdated and you need to tweak some config. Here'是如何使用github中的最新版本来完成的：

    // create the configuration in a place where it's more appropriate in your app
InstaSharpConfig = new InstagramConfig(
    apiURI, oauthURI, clientId, clientSecret, redirectUri);

// then here's a sample method you can have to initiate auth 
// and catch the redirect from Instagram
public ActionResult instagramauth(string code)
{
    if (string.IsNullOrWhiteSpace(code))
    {
        var scopes = new List<InstaSharp.Auth.Scope>();
        scopes.Add(InstaSharp.Auth.Scope.likes);
        var link = InstaSharp.Auth.AuthLink(
            oauthURI, clientId, redirectUri, scopes);
        // where:
        // oauthURI is https://api.instagram.com/oauth
        // clientId is in your Instagram account
        // redirectUri is the one you set in your Instagram account; 
        // for ex: http://yourdomain.com/instagramauth

        return Redirect(link);
    }

    // add this code to the auth object
    var auth = new InstaSharp.Auth(InstaSharpConfig);

    // now we have to call back to instagram and include the code they gave us
    // along with our client secret
    var oauthResponse = auth.RequestToken(code);

    // save oauthResponse in session or database, whatever suits your case

    // oauthResponse contains the field Access_Token (self-explanatory), 
    // and "User" that'll give you the user's full name, id, 
    // profile pic and username


    return RedirectToAction("action", "controller");
}

    请注意，您可以拆分“instagramauth”方法 . 这样做是为了简洁 .
