我是 PHP 编程的新手，目前我正在尝试将 aXenforo forum与我的网站集成。我想整合注册系统使用XenAPI plugin。我按照此页面上的指南进行操作，并且有效！

示例请求：

api.php?action=register&hash=d8e8fca2dc0f896fd7cb4cb0031ba249&username=Contex&password=My_Password&email=me@contex.me

回应是：

{
  "visible": 1,
  "user_group_id": 2,
  "user_state": "valid",
  "language_id": 1,
  "username": "Contex",
  "email": "me@contex.me",

  "remember_key": "11d20c2e9ffbbd7466a872dacf18051a47d94dce"
}

这是我的问题，如何将其中一个响应转换为 PHP 变量？

从"user_group_id": 2到$user_group_id = 2。

新问题

我得到了哈桑的答复，我按照他的指示，

我将我的 php 脚本编辑为如下所示：

$response = file_get_contents('http://forum.mydomain.com/api.php?action=getUsers&value=Contex&hash=Contex:9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08');
$response = json_decode($response, true);
echo $response->user_id;

我对其进行测试并收到一条新的错误消息。

Notice: Trying to get property of non-object.

如何解决？谢谢！

你需要使用json_decode()

$response = json_decode($str);
$user_group_id = $response->user_group_id;

echo $user_group_id;

注意替换$str为您的 API 响应变量。

尝试示例

$str = <<<JSON

{
  "visible": 1,
  "user_group_id": 2,
  "user_state": "valid",
  "language_id": 1,
  "username": "Contex",
  "email": "me@contex.me",
  "timezone": "Europe\/Berlin",
  "gender": "male",
  "style_id": 0,
  "secondary_group_ids": "",
  "display_style_group_id": 2,
  "permission_combination_id": 2,
  "message_count": 0,
  "alerts_unread": 0,
  "conversations_unread": 0,
  "register_date": 1368197942,
  "last_activity": 1368197942,
  "trophy_points": 0,
  "avatar_date": 0,
  "avatar_width": 0,
  "avatar_height": 0,
  "gravatar": "",
  "is_moderator": 0,
  "is_admin": 0,
  "is_banned": 0,
  "like_count": 0,
  "custom_title": "",
  "warning_points": 0,
  "user_id": 5,
  "dob_day": 27,
  "dob_month": 12,
  "dob_year": 1980,
  "csrf_token": "f5c36cd98569ae380b4c0383d8310954514ac64b",
  "status": "",
  "status_date": 0,
  "status_profile_post_id": 0,
  "signature": "",
  "homepage": "",
  "location": "",
  "occupation": "",
  "following": "",
  "ignored": "",
  "avatar_crop_x": 0,
  "avatar_crop_y": 0,
  "about": "",
  "facebook_auth_id": 0,
  "custom_fields": "",
  "content_show_signature": 1,
  "show_dob_date": 1,
  "show_dob_year": 1,
  "receive_admin_email": 1,
  "email_on_conversation": 1,
  "default_watch_state": "watch_email",
  "is_discouraged": 0,
  "alert_optout": "",
  "enable_rte": 1,
  "allow_view_profile": "everyone",
  "allow_post_profile": "members",
  "allow_receive_news_feed": "everyone",
  "allow_send_personal_conversation": "members",
  "allow_view_identities": "everyone",

  "data": "a:3:{s:4:\"hash\";s:64:\"f1a9f22e79366a9d7b8fcf18178d7bc95c8057ec6f8904b48809f24c2f40efdb\";s:4:\"salt\";s:64:\"f30d7f122f8db2f2c9f92755a667149ed524ae50ab1c0e2f269c4588f8e5835a\";s:8:\"hashFunc\";s:6:\"sha256\";}",
  "remember_key": "11d20c2e9ffbbd7466a872dacf18051a47d94dce"
}

JSON;


$response = json_decode($str);
$user_group_id = $response->user_group_id;

echo $user_group_id;
