问题描述
我使用了测试应用程序 id 并通过测试用户在 dash_board 应用程序上创建在 facebook 开发站点上登录,使用 facebook sdk 的登录按钮小部件登录时需要 pulish_actions 权限,但结果得到 postid 总是 = null.这是我的代码:

shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
@Override
public void onSuccess(Sharer.Result result) {
if (result.getPostId() != null)
Log.e(TAG, result.getPostId());
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException e) {
}
});
pulishButton.setOnClickListener(this);
try{
loginButton.setPublishPermissions(new String[]{"publish_actions","publish_stream"});
}catch (FacebookException e){
e.printStackTrace();
}
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.e(TAG, "success");
loginButton.setEnabled(false);
pulishButton.setEnabled(true);
GraphRequest.newMeRequest(
loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject json, GraphResponse response) {
if (response.getError() != null) {
// handle error
System.out.println("ERROR");
} else {
System.out.println("Success");
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}).executeAsync();
}
@Override
public void onCancel() {
Log.e(TAG, "On cancel");
}
@Override
public void onError(FacebookException e) {
Log.d(TAG, e.toString());
}
});
推荐答案
解决办法是强制ShareDialog使用Feed模式,避免使用FB的App进行分享:
The solution is to force ShareDialog to use Feed mode and avoid using FB's App for sharing:
shareDialog.show(linkContent, ShareDialog.Mode.FEED);
我相信这是 FB 的错误.使用 FB App 进行共享时,它们不会将 postId 发送到 onSuccess 回调(postId = null),但如果您使用 Feed,它们会发送.
I believe this is a bug by FB. They don't send postId to onSuccess callback when using FB App for sharing (postId = null), but they do if you use Feed.
我听说您可以通过使用 Facebook 登录并要求publish_actions"权限来避免postId=null"问题.但我不认为这是处理这个问题的正确方法.关于提到的许可 Facebook 声明:
I've heard you can avoid the "postId=null" problem by using Facebook Login and demanding "publish_actions" permission. But I don't think this is the correct way to deal with this problem. Regarding the mentioned permission Facebook states:
通过对话框或社交插件发布不需要此权限.如果您仅使用共享对话框、Feed 对话框、消息对话框等或社交插件(例如赞"按钮),请勿请求审核此权限.
Facebook 的共享对话框文档:
Facebook's docs on Share Dialog:
这不需要 Facebook 登录或任何扩展权限,因此它是在网络上启用共享的最简单方法.
