Xamarin表单-Instagram登录:收到无效的redirect_uri错误，如何解决? [英] Xamarin form - Instagram login: getting Invalid redirect_uri error, how to fix it?

问题描述

我已经使用Xamarin.Auth集成了Instagram登录，我提到了: Instagram基本显示api-入门 在那第一时间，我得到了:

I have integrate Instagram login using Xamarin.Auth, I have referred: Instagram basic display api - Getting Started and in that first I was getting:

{"error_type": "OAuthException", "code": 400, "error_message": "Invalid scope field(s): basic"}

然后我得到了这篇文章: C#Instagram-无效范围

Then I have got this post: 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.

So I have updated everything and I have created New App in developers.facebook.com console under Instagram Basic Display product as mentioned in Instagram Getting Started document.

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，但是现在我得到了

Then in code I have used that new App's App ID and also changed redirect url, also added Instagram Test users and they have accept invitations too, but now I am getting

{"error_type": "OAuthException", "code": 400, "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);

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);
