Question

我试图找出是否已为用户授予'publish_action'权限（使用php）。

我可以查询图表，我只是坚持解析响应，以便能够获得publish_actions ='grant'。

查询是：

$ user_permissions =   “https://graph.facebook.com/me/permissions?access_token=”   。$的access_token;

$ permissions = json_decode（file_get_contents（$ user_permissions））;

如果我打印回复

的print_r（$权限）;

我明白了......

stdClass对象（[data] =＆gt;数组（[0] =＆gt; stdClass对象（   [permission] =＆gt;安装[status] =＆gt;授予）[1] =＆gt; stdClass对象   （[权限] =＆gt; public_profile [status] =＆gt;已授予）[2] =＆gt; stdClass的   对象（[权限] =＆gt; publish_actions [status] =＆gt;已授予）））

捕获致命错误：无法转换类stdClass的对象   字符串

基本上我只想在php中分配一个变量如果publish_actions [status] =='grant'

对此的任何帮助将不胜感激。

更新

尝试下面的Sahil建议：

$user_permissions = "https://graph.facebook.com/me/permissions?access_token=" .$access_token;

$permissions = json_decode(file_get_contents($user_permissions, TRUE));

$hasPublishPerm = false;
print_r($permissions['data']);
print_r($permissions);
foreach($permissions['data'] as $permission){
   if($permission['permission']=="publish_actions" && 
      $permission['status']=="granted"){
        $hasPublishPerm = true;
        break;
   }
}

if($hasPublishPerm){
   echo "User has granted the publish permission";
}
else{
   echo "User has NOT granted the publish permission";
}

我收到此错误：

致命错误：不能将stdClass类型的对象用作...中的数组

就这样做 -

$hasPublishPerm = false;
foreach($permissions['data'] as $permission){
   if($permission['permission']=="publish_actions" && 
      $permission['status']=="grantedd"){
        $hasPublishPerm = true;
        break;
   }
}

if($hasPublishPerm){
   echo "User has granted the publish permission";
}
else{
   echo "User has NOT granted the publish permission";
}
