问题描述
我已经使用Xamarin.Auth集成了Instagram登录,我提到了: Instagram basic display api - Getting Started 那是我第一次得到:
{"error_type": "OAuthException","code": 400,"error_message": "Invalid scope field(s): basic"}
然后我得到了这篇文章:C# Instagram - Invalid Scope
因此,我已经更新了所有内容,并在Instagram入门文档中提到的Instagram Basic display产品下的developers.facebook.com控制台中创建了New App。
然后在代码中,我使用了该新App的App ID,还更改了重定向网址,还添加了Instagram Test用户,他们也接受了邀请,但现在我得到了
{"error_type": "OAuthException","error_message": "Invalid redirect_uri"}
验证码:
var authenticator = new OAuth2Authenticator(
clientId: Keys.InstagramClientId,scope: "basic",authorizeUrl: new Uri("https://api.instagram.com/oauth/authorize/?client_id=" + Keys.InstagramClientId + "&redirect_uri=https://localhost:3000/callback&response_type=token"),redirectUrl: new Uri("https://localhost:3000/callback"))
{
AllowCancel = true,ShowErrors = false,ClearCookiesBeforeLogin = true
};
AuthenticationState.Authenticator = authenticator;
authenticator.Error += (sender,eventArgs) =>
{
activity.Finish();
};
authenticator.Completed += (sender,eventArgs) =>
{
if (eventArgs.IsAuthenticated)
{
App.AccountType = "Instagram";
App.SaveAccount(eventArgs.Account,view.IsFromreauthentication);
}
};
var presenter = new Xamarin.Auth.Presenters.OAuthLoginPresenter();
presenter.Login(authenticator);
输出:
解决方法
最后,我让它成功了,分享一下它,对寻求解决方案的人可能会有帮助!
var authenticator = new OAuth2Authenticator(
// Id & App Secret of App you have created on FB developer console in Instagram Basic Display
clientId: Keys.InstagramAppId,clientSecret: Keys.InstagramAppSecret,// Basic scope is not supported anymore,this will fix Invalid scope error:
scope: "user_profile,user_media",authorizeUrl: new Uri("https://api.instagram.com/oauth/authorize/?client_id=" + Keys.InstagramAppId + "&redirect_uri=https://business.instagram.com/abc&response_type=token"),accessTokenUrl: new Uri("https://api.instagram.com/oauth/access_token/"),// Make sure that your redirect Url needs to register in developer console and it must be valid one
redirectUrl: new Uri("https://business.instagram.com/abc"))
{
AllowCancel = true,ShowErrors = false,ClearCookiesBeforeLogin = true,IsLoadableRedirectUri = false
};
AuthenticationState.Authenticator = authenticator;
authenticator.Error += (sender,eventArgs) =>
{
Debug.WriteLine($"Error - {eventArgs.Message}");
};
authenticator.Completed += (sender,eventArgs) =>
{
if (eventArgs.IsAuthenticated)
{
var userid = eventArgs.Account.Properties["user_id"];
var access_token = eventArgs.Account.Properties["access_token"];
}
};
var presenter = new Xamarin.Auth.Presenters.OAuthLoginPresenter();
presenter.Login(authenticator);
要获取用户信息:
Request details using :
