LinkedIn划线的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划线的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
我写了概念验证的应用程序使用隶的OAuth库连接到LinkedIn。
I'm writing a proof-of-concept app to connect to LinkedIn using the scribe OAuth library.
我能得到一个请求令牌，但我无法交流，对于一个访问令牌。我多次收到 oauth_problem = permission_unknown 的响应，尽管点击允许在LinkedIn上，我重定向到，当我问到身份验证。
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.
我已经注册了一个回调函数，这样当LinkedIn将用户重定向到我的回调，我的身份验证活动重新开始，在onResume我提取请求令牌和PIN code使用来获得访问令牌，这部分在至少似乎打算工作。
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.
我的code是在这里：
My code is here:
package com.rockrobot.example.scribelinkedin;
import org.scribe.builder.ServiceBuilder;
import org.scribe.builder.api.LinkedInApi;
import org.scribe.model.OAuthRequest;
import org.scribe.model.Response;
import org.scribe.model.Token;

import org.scribe.model.Verifier;
import org.scribe.oauth.OAuthService;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;
public class loginexample extends Activity {
private static OAuthService service;
private Token requestToken;
private Verifier verifier;
private static final String PROTECTED_RESOURCE_URL = "http://api.linkedin.com/v1/people/~/connections:(id,last-name)";
private static Boolean authInProgress = false;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if ( ! authInProgress ) {
authInProgress = true;
service = new ServiceBuilder()
.provider(LinkedInApi.class)
.apiKey("XXXXX")
.apiSecret("YYYYY")
.callback("callback://whodunit")
.build();
System.out.println("=== LinkedIn's OAuth Workflow ===");
System.out.println();
// Obtain the Request Token
System.out.println("Fetching the Request Token...");
requestToken = service.getRequestToken();
System.out.println("Got the Request Token!");
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! :)");
}
}
}
}
这是我的清单中的相关摘录在这里：
The relevant excerpt from my Manifest is here:
<activity android:name=".loginexample"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.VIEW"></action>
<category android:name="android.intent.category.BROWSABLE"></category>
<category android:name="android.intent.category.DEFAULT"></category>
<data android:host="whodunit" android:scheme="callback"></data>
</intent-filter>
</activity>
最后，我logcat的是在这里：
Finally, my logcat is here:

正如你可以在logcat中看到的，我收到的OAuth令牌和token_secret，但我不能互通，这些对于访问令牌，但不断收到 oauth_problem = permission_unknown 错误。
我知道LinkedIn自称是相当严格其实施的OAuth的，我只是不能似乎看到我要去哪里错了 - 也许我一直盯着太久已，这就是你们进来
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.
没有任何人有什么想法？ OAuth是不完全简单，但我不能相信它的这种复杂无论是。我可能失去了一些东西很明显，但就是无法找出它是什么。
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.
推荐答案
在你的 onResume 方法，你得到一个新的请求令牌，但是，验证code从你的的onCreate 方法得到的请求令牌。所以，你想用第二个请求令牌来获得访问令牌，但验证code对应的第一个请求令牌 - 因此，你没有发出一个访问令牌。有意义吗？
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?
如果你把 requestToken = service.getRequestToken（）; 从onResume方法，那么这应该工作作为一切看起来是正确的。
If you take out requestToken = service.getRequestToken(); from the onResume method then this should work as everything else looks correct.
