在Android上使用OAuth与抄写 [英] Using OAuth with Scribe on Android
问题描述
你好我使用的是与LinkedIn OAuth的通信隶库。
Hi I'm using the scribe library for OAuth communication with LInkedIn.
我有一个登录类和查询类。
I have a login class and a query class.
登录类创建一个服务，让我的请求令牌和秘密，并创建我的访问令牌。访问令牌，然后保存到preferences文件。这似乎很好地工作，我可以做一个成功的API调用，已创建的所有令牌后。
The login class creates a service to get my request token and secret and creates my access token. The access token is then saved to the preferences file. This seems to work fine and I can make a successful api call after all the tokens have been created.
在我的OAuth查询类我检索访问令牌，创建另一个服务，并设法使API调用，但是当我过负荷的活动，这使得调用这个类就导致我的应用程序崩溃。我已经测试，以确保访问令牌被保存，他们是。
In my OAuth query class i retrieve the access token, create another service and try to make an API call, but when ever I load an activity which makes calls this class it causes my app to crash. I have tested to make sure that the access token is saved and they are.
下面是我的登入分类
public class Login_LinkedIn extends Activity
{
SharedPreferences settings;
OAuthService service;
Token requestToken;
Button home;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.webauth);
initControls();
service = new ServiceBuilder()
.provider(LinkedInApi.class)
.apiKey( getString(R.string.apiKey) )
.apiSecret( getString(R.string.secKey) )
.callback( getString(R.string.callBack) )
.build();
requestToken = service.getRequestToken();
final String authURL = service.getAuthorizationUrl(requestToken);
final WebView webview = (WebView) findViewById(R.id.webView);
//attach WebViewClient to intercept the callback url
webview.setWebViewClient(new WebViewClient()
{
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
//check for our custom callback protocol
//otherwise use default behavior
if(url.startsWith( getString(R.string.callBack) ))
{
//authorization complete hide webview for now.
webview.setVisibility(View.GONE);
Uri uri = Uri.parse(url);
String verifier = uri.getQueryParameter("oauth_verifier");
Verifier v = new Verifier(verifier);
//save this token for practical use.
Token accessToken = service.getAccessToken(requestToken, v);
OAuthRequest request = new OAuthRequest(Verb.GET, "http://api.linkedin.com/v1/people/~:(first-name,last-name)");
service.signRequest(accessToken, request);
Response response = request.send();
xmlHandler xh = new xmlHandler(response.getBody());
settings = getSharedPreferences("preferences", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("accessToken", accessToken.getToken());
// The requestToken is saved for use later on to verify the OAuth request.
// See onResume() below
editor.putString("requestToken", requestToken.getToken());
editor.putString("requestSecret", requestToken.getSecret());
editor.putString("first-name", xh.getValue("first-name"));
editor.putString("last-name", xh.getValue("last-name"));
editor.commit();
return true;
}
return super.shouldOverrideUrlLoading(view, url);
}
});
//send user to authorization page
webview.loadUrl(authURL);
}
@Override
protected void onResume()
{
super.onResume();
Intent i = getIntent();
if(i != null)
{
Uri uri = i.getData();
if(uri != null)
{
String oauthVerifier = uri.getQueryParameter("oauth_verifier");
Verifier verifier = new Verifier(oauthVerifier);
requestToken = new Token(settings.getString("requestToken", null), settings.getString("requestSecret", null));
Token accessToken = service.getAccessToken(requestToken, verifier);
// Save the access token.
SharedPreferences.Editor editor = settings.edit();
editor.remove("requestToken");
editor.remove("requestSecret");
editor.putString("accessToken", accessToken.getToken());
editor.putString("accessSecret", accessToken.getSecret());
editor.commit();
// Start the film list activity.
final Intent intent = new Intent(this,ProConnect.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
}
}
private void initControls()
{
home = (Button)findViewById(R.id.home);
final Intent intent = new Intent(this,ProConnect.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
home.setOnClickListener(new Button.OnClickListener()
{
public void onClick (View v)
{
startActivity(intent);
}
});
}
}
和我的查询类
public class oAuthQuery extends Activity
{
OAuthService service;
Token accessToken;
SharedPreferences settings;
public oAuthQuery()
{
service= new ServiceBuilder()
.provider(LinkedInApi.class)
.apiKey( getString(R.string.apiKey) )
.apiSecret( getString(R.string.secKey) )
.callback( getString(R.string.callBack) )
.build();
settings = getSharedPreferences("preferences", 0);
accessToken = new Token(settings.getString("accessToken", null), settings.getString("accessSecret", null));
}
public String query(String s)
{
OAuthRequest request = new OAuthRequest(Verb.GET, s);
service.signRequest(accessToken, request);
Response response = request.send();
return response.getBody();
}
public OAuthService getService()
{
return service;
}
}

Thanks for any help Jeff
推荐答案
我解决了这个问题，这是一件愚蠢进行到底。我已经编辑我的code保存访问密钥和访问令牌，但已经忘记了我的手机上测试我的应用程序时，重新登录。这导致在其中保存没有被达到令牌的部件的code
I solved the problem it was something stupid in the end. I had edited my code to save the access secret and the the access token but had forgotten to re-login when testing my app on my phone. This resulted in the code which saved the parts of the token was not being reached.
我用邀请LinkedIn的API调用中仍然有一个问题
I still have a problem using the invite call in the LinkedIn API
invite.setOnClickListener(new Button.OnClickListener()
{
public void onClick (View v)
{
inviteXml = inviteCreator.inviteString(to, subj, body, authName, authValue);
nameField.setText(inviteXml);
titleField.setText("");
call = "http://api.linkedin.com/v1/people/~/mailbox";
request = new OAuthRequest(Verb.GET, call);
request.addPayload(inviteXml);
service.signRequest(accessToken, request);
response = request.send();
invite.setVisibility(View.GONE);
}
});
我不知道这是否是XML字符串添加到呼叫的正确方法。 LinkedIn的API不指定它是如何被添加。有没有人有这方面的经验？
I'm not sure if this is the correct way to add the XML string to the call. The LinkedIn API doesn't specify how it is to be added. Has anyone any experience with this?
