Amazon Cognito:如何停止获取"redirect_mismatch"从浏览器重定向到Android应用时出错 [英] Amazon Cognito: How to stop getting "redirect_mismatch" error when redirecting from browser to Android app

问题描述

我正在尝试创建一个Android项目，在该项目中我授权用户，方法是让用户在浏览器中登录Amazon Cognito，然后应重定向回我的应用.不幸的是，当浏览器打开时，没有到达正确的登录页面，而是不断出现此错误:

I am trying to create a Android project where I authorize a user by having him log into Amazon Cognito in a browser, which should then redirect back to my app. Unfortunately, when the browser opens, instead of reaching the proper sign-in page, I keep getting this error:

在我的AuthenticatorActivity.java中:

In my AuthenticatorActivity.java:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_authenticator);

    Uri authzUrl = Uri.parse("https://<myDomain>.auth.us-west-2.amazoncognito.com/login?response_type=token&client_id=<myClientId>&redirect_uri=myapp://mainAct");
    Intent launchBrowser = new Intent(Intent.ACTION_VIEW, authzUrl);
    startActivity(launchBrowser);
}

在AndroidManifest中:

In AndroidManifest:

<activity android:name=".MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:host="mainAct" android:scheme="myapp"></data>
    </intent-filter>
</activity>

我无法弄清楚我在做什么错.我错过了一步吗?

I can't figure out what I am doing wrong here. Am I missing a step?

推荐答案

好吧，我在这里留下一个小窍门，以供下一个可能找到它的人使用.我遇到了完全相同的问题，但是作为Cognito和IdP/SSO的新手，我不知道如何解决此问题.这是我为最终解决此问题所做的工作.我们正在与外部服务集成，并且遇到了此错误.在Chrome开发者工具->网络下，我开始记录URL的访问，然后再次尝试SSO集成.列表中显示了一个URL，该URL通过重定向到URL访问了Cognito.该URL必须与Cognito的回调URL"下列出的URL相同.

Ok, I'm leaving a tidbit here for whoever might find it next. I hit this issue exact same issue, but as a newbie to Cognito and IdP/SSO I had no idea how to fix this. Here is what I did to eventually fix this. We were integrating with an external service, and we were getting this error. Under Chrome Developer Tools -> Network, I started to record the URL's visited, then I tried the SSO integration again. There was a URL that showed up in the list which visited Cognito with a redirect to URL. That URL must be the same URL as listed under the Callback URL for Cognito.

希望这可以节省将来的时间.

Hopefully, this saves someone some time in the future.
