LinkedIn scribe OAuth 库无法允许访问 LinkedIn 帐户 [英] LinkedIn scribe OAuth library unable to allow access to LinkedIn account
本文介绍了LinkedIn scribe OAuth 库无法允许访问 LinkedIn 帐户的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在编写一个概念验证应用程序，以使用 scribe OAuth 库连接到 LinkedIn.>
我可以获得请求令牌，但无法将其交换为访问令牌.我反复收到 oauth_problem=permission_unknown 响应，尽管点击了 LinkedIn 上的允许"，当我被要求进行身份验证时，我会重定向到该响应.
我已经注册了一个回调，以便当 LinkedIn 将用户重定向到我的回调时，我的身份验证活动将恢复，并且在 onResume 我提取请求令牌和 PIN 码以用于获取访问令牌，这部分至少似乎按预期工作.
我的代码在这里:

我知道 LinkedIn 声称他们对 OAuth 的实施相当严格，但我似乎无法看看我哪里出错了 - 也许我已经盯着它看太久了，这就是你们进来的地方.
有人有什么想法吗?OAuth 并不完全简单，但我也不敢相信它这么复杂.我可能遗漏了一些明显的东西，但就是无法弄清楚它是什么.
解决方案
在您的 onResume 方法中，您将获得一个新的请求令牌，但是，验证码来自您在onCreate 方法.因此，您尝试使用第二个请求令牌获取访问令牌，但验证码对应于第一个请求令牌 - 因此，您未获得访问令牌.有道理吗?
如果你从 onResume 方法中取出 requestToken = service.getRequestToken(); 那么这应该可以正常工作，因为其他一切看起来都是正确的.
I'm writing a proof-of-concept app to connect to LinkedIn using the scribe OAuth library.
I can get a request Token, but am unable to exchange that for an access token. I am repeatedly receiving the oauth_problem=permission_unknown response, despite clicking the 'allow' on LinkedIn that I am redirected to when I am asked to authenticate.
I've registered a callback so that when LinkedIn redirects the user to my callback, my authentication activity is resumed and in onResume I extract the request token and PIN code to use to get an access token and this part at least seems to be working as intended.
My code is here:

System.out.println();
System.out.println("Now go and authorize Scribe here:");
System.out.println(service.getAuthorizationUrl(requestToken));
Toast.makeText(this, "Please authorize " + getString(R.string.app_name), Toast.LENGTH_LONG).show();
startActivity (new Intent ( Intent.ACTION_VIEW, Uri.parse(service.getAuthorizationUrl(requestToken))));
}
}
@Override
protected void onResume() {
super.onResume();
if (this.getIntent()!=null && this.getIntent().getData()!=null){
Uri uri = this.getIntent().getData();
if (uri != null && uri.toString().startsWith("callback://whodunit")) {
verifier = new Verifier ( uri.getQueryParameter("oauth_verifier") );
// Trade the Request Token and Verfier for the Access Token
requestToken = service.getRequestToken();
System.out.println("Trading the Request Token for an Access Token...");
System.out.println(" ---> Request Token: " + requestToken.getToken());
System.out.println(" ---> Request Token Secret: " + requestToken.getSecret());
System.out.println(" ---> Verifier: " + verifier.getValue());
Token accessToken = service.getAccessToken(requestToken, verifier);
System.out.println("Got the Access Token!");
System.out.println("(if you're curious it looks like this: " + accessToken + " )");
System.out.println();
// Now let's go and ask for a protected resource!
System.out.println("Now we're going to access a protected resource...");
OAuthRequest request = new OAuthRequest(Verb.GET, PROTECTED_RESOURCE_URL);
service.signRequest(accessToken, request);
Response response = request.send();
System.out.println("Got it! Lets see what we found...");
System.out.println();
System.out.println(response.getBody());
System.out.println();
System.out.println("Thats it man! Go and build something awesome with Scribe! :)");
}
}
}
}
The relevant excerpt from my Manifest is here:

android:label="@string/app_name">

As you can see in the logcat, I'm getting an oauth token and token_secret, but I am unable to exchange these for the access token but keep getting the oauth_problem=permission_unknown error.
I know LinkedIn claim to be rather strict with their implementation of OAuth, I just can't seem to see where I'm going wrong - maybe I've been staring at it for too long already, which is where you guys come in.
Does anybody have any ideas? OAuth isn't exactly simple, but I can't believe it's this complicated either. I'm probably missing something obvious, but just can't work out what it is.

In your onResume method you're getting a new request token but, the verification code is from the request token you got in the onCreate method. So, you're trying to get an access token using the second request token but the verification code corresponds to the first request token - hence, you're not issued an access token. Make sense?
If you take out requestToken = service.getRequestToken(); from the onResume method then this should work as everything else looks correct.
