Like posts over Facebook graph api
提问by simekadam
HI! I have little problem with facebook PHP SDK..I want to like a post, or something else via facebook PHP SDK..I am doing this code, I think it should be right, but ?apparently it's not working..The given error code is, the PHP SDK dont know this kind of POST request(the generated link is definitely alright). What I have seen on Facebook Developers page is about the same..There is an example of Curl command, and I the PHP SDK is doing this requests over Curl (propably).
你好！我对 facebook PHP SDK 没有什么问题。代码是，PHP SDK不知道这种POST请求（生成的链接肯定没问题）。我在 Facebook 开发人员页面上看到的内容大致相同..有一个 Curl 命令示例，我的 PHP SDK 正在通过 Curl 执行此请求（可能）。
$this->getFacebook()->api("/"+$id+"/likes", 'post');This is what I am using in my code and it's not working(Facebook API Exception unsupported post request).
$this->getFacebook()->api("/"+$id+"/likes", 'post');这是我在我的代码中使用的，但它不起作用（Facebook API 异常不受支持的发布请求）。
Maybe, I have bad syntax in my code, but, for example, when I want to post a status to my Profile, it's working..Another cause which confused me, was when I tried to fetch these data over Graph api(on the documentation page is written, I should use address like graph.facebook.com/POST_ID/likes)...
也许，我的代码中有错误的语法，但是，例如，当我想将状态发布到我的个人资料时，它正在工作..另一个让我感到困惑的原因是，当我试图通过 Graph api（在文档页面已写好，我应该使用像graph.facebook.com/POST_ID/likes）这样的地址...
You can comment on or like a post by posting tohttps://graph.facebook.com/POST_ID/commentsandhttps://graph.facebook.com/POST_ID/likes,respectively:
您可以在或喜欢一个帖子中发布评论https://graph.facebook.com/POST_ID/comments和https://graph.facebook.com/POST_ID/likes，分别为：
curl -F 'access_token=...' \
https://graph.facebook.com/313449204401/likes<=this is from facebook documentation
curl -F 'access_token=...' \
https://graph.facebook.com/313449204401/likes<=这是来自facebook文档
And all these requests or commands(liking ones, comments have I not yet tried) are putting me back a JSON array which contents any already existing likes, but my like is nowhere.
所有这些请求或命令（喜欢的，我还没有尝试过的评论）让我回到一个 JSON 数组，其中包含任何已经存在的喜欢，但我的喜欢无处可去。
Does anyone know what to do?How to like a post from PHP..There are other SKDs like FQL, but I haven't any knowlegde with it, so I like rather to use the standard PHP SDK(but if is there some possibility how to call for example FQL from PHP SDK, here I am:))
有谁知道该怎么做？如何喜欢来自 PHP 的帖子..还有其他像 FQL 这样的 SKD，但我对它一无所知，所以我更喜欢使用标准的 PHP SDK（但如果有一些可能性如何从 PHP SDK 调用例如 FQL，我在这里:))
Please help..
请帮忙..

Okay, after a couple of tests don't use the plus sign +when sending the parameter as the ID alone will be send as argument to the apimethod without /and /likesso use:
好的，经过几次测试后，+在发送参数时不要使用加号，因为单独的 ID 将作为参数发送给api方法/，/likes因此使用：
$this->getFacebook()->api("/".$id."/likes", 'post');
Or even better:
或者甚至更好：
$this->getFacebook()->api("/$id/likes", 'post');
Also make sure that you have the publish_streamextended permission, refer to this document.
还要确保您具有publish_stream扩展权限，请参阅此文档。

View who likes object with id $id:
查看谁喜欢带有 id $id 的对象：
$this->getFacebook()->api("/$id/likes", 'get');
Add like to object with id $id:
将 like 添加到带有 id $id 的对象：
$this->getFacebook()->api("/$id/likes", 'post');
Remove like from object with id $id:
从 id 为 $id 的对象中删除 like：
$this->getFacebook()->api("/$id/likes", 'delete');
Make sure you have the publish_stream permission to post and delete likes.
确保您拥有发布和删除赞的 publish_stream 权限。
An easy wasy to experiment with this is through the facebook graphapi explorer.
一个简单的实验是通过 facebook graphapi explorer。
