无法使用 Facebook API 获取位置和电子邮件 [英] Can't get location and email using Facebook API
问题描述
在我的 Android 应用程序中，我开发了此代码以使用我的帐户登录并获取用户属性，例如姓名、位置和电子邮件.问题是我可以得到名字，但我无法得到电子邮件和位置.当我尝试我的代码而不尝试捕获应用程序崩溃和我在 getproperty("email") 和 getlocation() 中的日志点时.当我使用 try.应用程序有效，但没有电子邮件或位置.
In my Android application I developed this code to login with my account and get user property like name, location and email. The problem is I can get the name, but I can't get the email and the location. When I tried my code without try catch the application crush and my log point in getproperty("email") and getlocation(). When I use the try. The application work but there is no email or location.

推荐答案
问题是您没有请求权限:
The issue is that you have not asked for permissions:
authButton.setReadPermissions(Arrays.asList("user_likes", "user_status","email","user_birthday"));
但是，您使用的是较旧的 Facebook SDK，而 最新的 SDK 是 4.0.+.下面，我将基于最新的 API 为您提供 Facebook 登录的完整示例代码.请记住，您首先必须在 developers.facebook 中添加您的应用程序作为 文档 提到了.
However, you are using an older Facebook SDK, while the newest SDK is 4.0.+. Below, I will give you a full sample code for Facebook login, based on the newest API. Keep in mind that you first have to add your application in developers.facebook as the documentation mentions out.
public class LoginActivity extends ActionBarActivity{
@Override
protected void onActivityResult(int requestCode, int responseCode, Intent data)
{
super.onActivityResult(requestCode, responseCode, data);
callbackManager.onActivityResult(requestCode, responseCode, data);
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(this.getApplicationContext());
setContentView(R.layout.activity_login);
callbackManager = CallbackManager.Factory.create();
loginButton = (LoginButton) findViewById(R.id.loginFaceBook_button);
List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile");
loginButton.setReadPermissions(permissionNeeds);
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>()
{
@Override
public void onSuccess(LoginResult loginResult)
{
System.out.println("onSuccess");
GraphRequest request = GraphRequest.newMeRequest
(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback()
{
@Override
public void onCompleted(JSONObject object, GraphResponse response)
{
// Application code
Log.v("LoginActivity", response.toString());
//System.out.println("Check: " + response.toString());
try
{
String id = object.getString("id");
String name = object.getString("name");
String email = object.getString("email");
String gender = object.getString("gender");
String birthday = object.getString("birthday");
System.out.println(id + ", " + name + ", " + email + ", " + gender + ", " + birthday);
}
catch (JSONException e)
{
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel()
{
System.out.println("onCancel");
}
@Override
public void onError(FacebookException exception)
{
System.out.println("onError");
Log.v("LoginActivity", exception.getCause().toString());
}
});
}
}
如果您想使用 Fragment 而不是 ActionBarActivity，只需在您的权限行后面添加 loginButton.setFragment(this); 即可.
If you want to use Fragment instead of ActionBarActivity, the just add loginButton.setFragment(this); right after your permission line.
manifest.xml:
manifest.xml:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<application
<!-- your other attrs..-->
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/app_id"/> <!-- Get this one from developers.facebook -->
<activity
android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name"/>
您还需要向您的应用程序添加一个哈希键.这是一种使用代码执行此操作的方法:
You will need to add to your application a hash key too. Here is a way to do this with code:
try
{
//paste Your package name at the first parameter
PackageInfo info = getPackageManager().getPackageInfo("PUT_YOUR_PACKAGE_NAME_HERE",
PackageManager.GET_SIGNATURES);
for (android.content.pm.Signature signature : info.signatures)
{
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String sign = Base64.encodeToString(md.digest(), Base64.DEFAULT);
Log.e("MY KEY HASH:", sign);
Toast.makeText(getApplicationContext(),sign, Toast.LENGTH_LONG).show();
}
}
catch (PackageManager.NameNotFoundException e)
{
}
catch (NoSuchAlgorithmException e)
{
}
在它打印出哈希键后，您将其复制粘贴到您的项目所在的 facebook.developer 帐户.
After it prints you out the hash key, you copy paste it to your facebook.developer account, where your project is located.
在grandle中，您应该在repositories中添加jcenter并添加compile 'com.facebook.android:facebook-android-sdk:4.0.0' 在 dependecies 中.
In grandle, you should add jcenter in repositories and also add compile 'com.facebook.android:facebook-android-sdk:4.0.0' in dependecies.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects
{
repositories {
jcenter()
/*more project attrs..*/
}
}
还有另一个grandle文件:
And the other grandle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "YOUR_PACKAGE_NAME"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
}
为了跟踪用户的位置，您需要一个 GPS 跟踪器，例如 这个."user_location" 权限不返回 lon, lat，而是一个 Page 对象，我认为这不是您想要的.所以，你的权限应该是 List 现在你应该可以检索用户的电子邮件了
In order to track the user's location, you will need a GPS Tracker, something like this. "user_location" permission does not return a lon, lat, but a Page object, which I think is not what you want. So, your permissions should be List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile"); and now you should be able to retrieve user's email
