【问题描述】：
我正在尝试打开用户的 Facebook 个人资料页面，如 here 所示。在我的应用程序中，用户在授予我的应用程序权限后登录，我得到了常用的详细信息，如 FB ID、姓名、电子邮件等。但我无法使用 FB ID 在浏览器中打开个人资料页面。还有其他方式可以显示个人资料页面吗？
public class MainActivity extends AppCompatActivity {
CallbackManager callbackManager;
AccessTokenTracker accessTokenTracker;
AccessToken accessToken;
String fbid;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FacebookSdk.sdkInitialize(getApplicationContext());
facebookOncreateCalling();
Button loginbtn = (Button) findViewById(R.id.loginbtn);
loginbtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
LoginManager.getInstance().logOut();
} catch (Exception e) {
e.printStackTrace();
}
LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("public_profile", "user_friends", "email", "user_birthday", "user_about_me"));
}
});
// Here I want to open facebook profile page in browser

}【问题讨论】：
-
“正如我在一些 SO 帖子中看到的，用户名权限已被弃用” - 从来没有这样的权限...
username字段 已使用 API v2.0 从用户对象中删除。 -
那么如果没有办法获取用户名，如何使用FB ID打开用户的个人资料？我正在为 same@CBroe 编辑我的问题
-
只需从用户配置文件中请求
link字段，它会为您提供https://www.facebook.com/app_scoped_user_id/123456789/形式的URL，并且在浏览器中调用时将重定向到用户的实际配置文件地址。跨度>
