我想我发现有一种解决方法.

蒸汽openid可以像这样一个url请求使用：

https://steamcommunity.com/openid/login?

openid.claimed_id=http://specs.openid.net/auth/2.0/identifier_select&

openid.identity=http://specs.openid.net/auth/2.0/identifier_select&

openid.mode=checkid_setup&

openid.ns=http://specs.openid.net/auth/2.0&

openid.realm=https://REALM_PARAM&

openid.return_to=https://REALM_PARAM/signin/

其中REALM_PARAM是将出现在登录屏幕上的网站,此外,用户在身份验证完成后将被重定向到该网站,不需要真正存在.

所有你需要做的是解析用户id的新url.

所以我用这样的东西

public class LoginActivity extends ActionBarActivity {

// The string will appear to the user in the login screen

// you can put your app's name

final String REALM_PARAM = "YourAppName";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

final WebView webView = new WebView(this);

webView.getSettings().setJavaScriptEnabled(true);

final Activity activity = this;

webView.setWebViewClient(new WebViewClient() {

@Override

public void onPageStarted(WebView view, String url,

Bitmap favicon) {

//checks the url being loaded

setTitle(url);

Uri Url = Uri.parse(url);

if(Url.getAuthority().equals(REALM_PARAM.toLowerCase())){

// That means that authentication is finished and the url contains user's id.

webView.stopLoading();

// Extracts user id.

Uri userAccountUrl = Uri.parse(Url.getQueryParameter("openid.identity"));

String userId = userAccountUrl.getLastPathSegment();

// Do whatever you want with the user's steam id

});

setContentView(webView);

// Constructing openid url request

String url = "https://steamcommunity.com/openid/login?" +

"openid.claimed_id=http://specs.openid.net/auth/2.0/identifier_select&" +

"openid.identity=http://specs.openid.net/auth/2.0/identifier_select&" +

"openid.mode=checkid_setup&" +

"openid.ns=http://specs.openid.net/auth/2.0&" +

"openid.realm=https://" + REALM_PARAM + "&" +

"openid.return_to=https://" + REALM_PARAM + "/signin/";

webView.loadUrl(url);

}

}
