facebook graph api 从 2.2 到 2.3 不起作用 [英] facebook graph api not work from 2.2 to 2.3
问题描述
由于图形 api 2.2 的截止日期,我正在尝试使用 v2.3 修复我的图形 api但是当我使用 2.3 时,我发现大多数 api 请求响应什么都没有,但是我在升级文档中找不到任何更新.例如:
Because it's due date for graph api 2.2, I'm trying fix my graph api using v2.3 But I discover most api request response nothing when I use 2.3, but I can not found any update for this in the upgrade document. For example:
https://graph.facebook.com/v2.3/{$user_id}?date_format=U&fields=albums.order(reverse_chronological).limit(100).offset(0){id,count,name,created_time}
如果我使用 2.3 将不返回任何内容.我打电话时无法获得用户的生日:
will return nothing if I use 2.3. And I can't get user's birthday when I call:
https://graph.facebook.com/v2.3/{$user_id}
它只是返回名称和实时位置.但在 v2.2 中,它包含生日资料.
It's only return name and live location. But in v2.2, it include birthday profile.
我使用 facebook SDK 3.2.2,因为我的 php 版本是 5.3.有什么我不知道的更新吗?谢谢.
I use facebook SDK 3.2.2 because my php version is 5.3. Is there any update that I don't know? Thanks.
推荐答案
我自己发现了这个问题.这是因为 SDK 3.2.2.对于 facebook 更新(来自 API 2.3 版的 Changelog):
I have found the problem myself. It's because the SDK 3.2.2. For facebook update (from the Changelog for API version 2.3):
[Oauth Access Token] Format - https://www.facebook的响应格式当您为 access_token 交换代码时返回的 .com/v2.3/oauth/access_token 现在返回有效的 JSON 而不是 URL 编码.此响应的新格式为 {"access_token": {TOKEN}, "token_type":{TYPE}, "expires_in":{TIME}}.我们进行了此更新以符合 RFC 6749 的第 5.1 节.
[Oauth Access Token] Format - The response format of https://www.facebook.com/v2.3/oauth/access_token returned when you exchange a code for an access_token now return valid JSON instead of being URL encoded. The new format of this response is {"access_token": {TOKEN}, "token_type":{TYPE}, "expires_in":{TIME}}. We made this update to be compliant with section 5.1 of RFC 6749.
但 SDK 将响应识别为数组(在 getAccessTokenFromCode 函数中):
But SDK is recognize the response as an array(in the getAccessTokenFromCode function):
$response_params = array();
parse_str($access_token_response, $response_params);
if (!isset($response_params['access_token'])) {
return false;
}
return $response_params['access_token'];
这将无法正确获取用户访问令牌,并且您无法获取用户数据.所以你应该更新这个函数来解析数据为json:
This will not get user access token correctly, and you can't get user's data. So you should update this function to parse data as json:
$response = json_decode($access_token_response);
if (!isset($response->access_token)) {
return false;
}
return $response->access_token;
然后所有的功能都会照常工作.
Then all of the function will work as usual.
此外,您必须对 setExtendedAccessToken()
进行类似的更改.否则,您的应用程序将无法扩展访问令牌.下面的代码演示了如何升级功能.
Additionally, you must make similar changes to setExtendedAccessToken()
. Otherwise, your app won't be able to extend access tokens. The code below demonstrates how to upgrade the function.
/**
* Extend an access token, while removing the short-lived token that might
* have been generated via client-side flow. Thanks to http://bit.ly/ b0Pt0H
* for the workaround.
*/
public function setExtendedAccessToken() {
try {
// need to circumvent json_decode by calling _oauthRequest
// directly, since response isn't JSON format.
$access_token_response = $this->_oauthRequest(
$this->getUrl('graph', '/oauth/access_token'),
$params = array(
'client_id' => $this->getAppId(),
'client_secret' => $this->getAppSecret(),
'grant_type' => 'fb_exchange_token',
'fb_exchange_token' => $this->getAccessToken(),
)
);
}
catch (FacebookApiException $e) {
// most likely that user very recently revoked authorization.
// In any event, we don't have an access token, so say so.
return false;
}
if (empty($access_token_response)) {
return false;
}
//Version 2.2 and down (Deprecated). For more info, see http://stackoverflow.com/a/43016312/114558
// $response_params = array();
// parse_str($access_token_response, $response_params);
//
// if (!isset($response_params['access_token'])) {
// return false;
// }
//
// $this->destroySession();
//
// $this->setPersistentData(
// 'access_token', $response_params['access_token']
// );
//Version 2.3 and up.
$response = json_decode($access_token_response);
if (!isset($response->access_token)) {
return false;
}
$this->destroySession();
$this->setPersistentData(
'access_token', $response->access_token
);
}
