DiscuzX3.5发帖json api

参考文章：PHP实现独立Discuz站外发帖(直连操作数据库)_discuz 发帖api-CSDN博客

简单改造了一下，适配我自己的需求

有一个站点存在多个采集站，我想通过主站拿标题，采集站拿内容

使用到的sql如下

CREATE TABLE `pre_forum_post_sync`  (
                                        `id` int(0) NOT NULL AUTO_INCREMENT,
                                        `foreign_id` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL,
                                        `foreign2_id` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL,
                                        `foreign3_id` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL,
                                        `tid` int(0) NOT NULL,
                                        `pid` int(0) NOT NULL,
                                        `update_time` int(0) NULL DEFAULT NULL,
                                        PRIMARY KEY (`id`) USING BTREE,
                                        UNIQUE INDEX `foreign_id`(`foreign_id`) USING BTREE
) ENGINE = InnoDB  CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci ROW_FORMAT = Dynamic;


CREATE TABLE `pre_wechat_push_log` (
                                       `id` BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
                                       `tid` INT NOT NULL COMMENT '主题ID',
                                       `pid` INT NOT NULL COMMENT '帖子ID',
                                       `push_time` DATETIME DEFAULT CURRENT_TIMESTAMP COMMENT '推送时间'
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

使用方法

curl --location 'http://d.example.com/topic_only.php' \
--header 'AccessKey: my-access-key' \
--header 'AccessSecret: my-access-secret' \
--header 'Content-Type: application/json' \
--data '{
  "fid": "2",
  "title": "测试标题0816",
  "content": "这是一个测试内容。",
  "foreign_id": "9966",
  "post_time": "2024-08-16 10:00:00"
}
'

跟参考的代码相比，这里做了一个简单的鉴权，AccessKey AccessSecret与php代码里保持一致才可调用。本来像参考oss写个签名方法，还是先不搞这么复杂了。

由于采集站没有源站帖子id，则写一个根据标题更新内容的api

update_by_title.php

 'error', 'message' => 'Missing AccessKey or AccessSecret']);
    exit;
}

if ($headers['accesskey'] !== ACCESS_KEY || $headers['accesssecret'] !== ACCESS_SECRET) {
    http_response_code(403);
    echo json_encode(['status' => 'error', 'message' => 'Invalid AccessKey or AccessSecret']);
    exit;
}

// 接收并解析 JSON 输入
$input = file_get_contents('php://input');
$data = json_decode($input, true);

// 检查必要字段
   if (!isset($data['fid'], $data['title'], $data['content']) ||
       (!isset($data['foreign2_id']) && !isset($data['foreign3_id']))) {
       echo json_encode(['status' => 'error', 'message' => 'Missing required parameters: fid, title, content, and either foreign2_id or foreign3_id']);
       exit;
   }


$fid = $data['fid'];
$title = $data['title'];
$content = $data['content'];
$foreign2_id = $data['foreign2_id'] ?? null;
$foreign3_id = $data['foreign3_id'] ?? null;


try {
    // 初始化数据库连接
    $con = mysqli_connect('mysql', 'root', 'pass', 'ultrax', 3306);
    if (!$con) {
        throw new Exception("Database connection failed");
    }

    // 查找 title 对应的主题 ID(tid)
    $sql = "SELECT tid FROM pre_forum_thread WHERE subject = '{$title}' AND fid = '{$fid}' LIMIT 1";
    $res = mysqli_query($con, $sql);

    if (!$res || mysqli_num_rows($res) === 0) {
        throw new Exception("No thread found with the given title and fid");
    }

    $row = mysqli_fetch_assoc($res);
    $tid = $row['tid'];

    // 获取主帖 pid（通常 position = 1）
    $sql = "SELECT pid FROM pre_forum_post WHERE tid = '{$tid}' AND position = 1 ORDER BY dateline DESC LIMIT 1";
    $res = mysqli_query($con, $sql);

    if (!$res || mysqli_num_rows($res) === 0) {
        throw new Exception("Main post not found for the thread");
    }

    $row = mysqli_fetch_assoc($res);
    $pid = $row['pid'];

    // 更新帖子内容
    $sql = "UPDATE pre_forum_post SET message = '{$content}' WHERE pid = '{$pid}'";
    if (!mysqli_query($con, $sql)) {
        throw new Exception("Update post content failed: " . mysqli_error($con));
    }

    // 更新同步记录表中的 foreign2_id
    if (isset($data['foreign2_id'])) {
       // 更新 foreign2_id 字段
       $sql = "UPDATE pre_forum_post_sync
               SET foreign2_id = '{$foreign2_id}'
               WHERE tid = '{$tid}' AND pid = '{$pid}'";
    } elseif (isset($data['foreign3_id'])) {
       // 新增 foreign3_id 字段更新逻辑
       $sql = "UPDATE pre_forum_post_sync
               SET foreign3_id = '{$foreign3_id}'
               WHERE tid = '{$tid}' AND pid = '{$pid}'";
    }

    if (!mysqli_query($con, $sql)) {
       throw new Exception("Update sync record failed: " . mysqli_error($con));
    }

   $updateFields = [];
   if (isset($data['foreign2_id'])) {
       $updateFields[] = 'foreign2_id';
   }
   if (isset($data['foreign3_id'])) {
       $updateFields[] = 'foreign3_id';
   }

   echo json_encode([
       'status' => 'success',
       'data' => [
           'tid' => $tid,
           'pid' => $pid,
           'updated_fields' => $updateFields,
           'message' => 'Post updated successfully'
       ]
   ]);

} catch (Exception $e) {
    echo json_encode(['status' => 'error', 'message' => $e->getMessage()]);
}

使用方法

curl --location 'https://d.example.com/update_by_title.php' \
--header 'AccessKey: my-access-key' \
--header 'AccessSecret: my-access-secret' \
--header 'Content-Type: application/json' \
--data '{
  "fid": "2",
  "title": "测试标题",
  "content": "这是一个测试内容8888872",
  "foreign3_id": "123456"
}
'

 这里 "foreign3_id": "123456"也可以改成  "foreign2_id": "123456"，当有多个采集站时扩充数据库字段修改代码即可。

这里用post get都可以。

把这3个php文件防弹discuz安装目录下，后续就可以通过调用API实现帖子同步和新帖通知操作了。
