我有一个带有public class fb extends Activity {
Button fbbt1;
CallbackManager callbackManager;
AccessTokenTracker accessTokenTracker;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fb);
try {
FacebookSdk.sdkInitialize(getApplicationContext());
fbbt1 = (Button) findViewById(R.id.fbbutton);
callbackManager = CallbackManager.Factory.create();
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
}
@Override
public void onCancel() {
// App code
// savedInstanceState
}
@Override
public void onError(FacebookException exception) {
// App code
Toast.makeText(fb.this, exception.toString(), Toast.LENGTH_LONG).show();
}
});
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile, user_groups"));
accessTokenTracker = new AccessTokenTracker() {
@Override
protected void onCurrentAccessTokenChanged(
AccessToken oldAccessToken,
AccessToken currentAccessToken) {
}
};
fbbt1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
getUserData(AccessToken.getCurrentAccessToken());
Toast.makeText(fb.this, "Access Token: "+ AccessToken.getCurrentAccessToken().getToken().toString(), Toast.LENGTH_LONG).show();
}
catch (Exception e){
Toast.makeText(fb.this, "error is: "+e.toString(), Toast.LENGTH_LONG).show();
}
}
});
}
catch (Exception e){
Toast.makeText(fb.this, e.toString(), Toast.LENGTH_LONG).show();
}
}
public void getUserData(AccessToken accessToken){
GraphRequest.newGraphPathRequest(
accessToken, "/ 415004402015833/posts",
new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse graphResponse) {
try {
Toast.makeText(fb.this, "Object Length is : " + graphResponse.getJSONObject().length(), Toast.LENGTH_LONG).show();
Toast.makeText(fb.this, "request was: " + graphResponse.getRequest(), Toast.LENGTH_LONG).show();
String resp = graphResponse.getRawResponse();
Toast.makeText(fb.this, "response is: " + resp, Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(fb.this, "error is: " + e.toString(), Toast.LENGTH_LONG).show();
}
}
}).executeAsync();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
@Override
protected void onDestroy() {
super.onDestroy();
try{
accessTokenTracker.stopTracking();}
catch (Exception e){
Toast.makeText(fb.this, "error is: "+e.toString(), Toast.LENGTH_LONG).show();
}
}
}
属性的模型（类别），我为此定义了一条路线：
:name问题是，某些类别的名称包含字符＆＃34; /＆＃34;。因此，例如，如果某个类别被命名为＆＃34;药物/药房＆＃34;，那么该网址将被解释为get ':name' => 'categories#show'
，而不是categories#Drugs#Pharmacy。
还有其他人遇到过这个问题吗？我怎么能绕过这个？我想我可以从每个网址中删除该字符，但如果我能以某种方式包含它，那将会很酷。
