这里我使用的是多轮
public function run() {
$user_id = 1;//用户ID
$msg = "如何成为更好的人";//用户聊天内容
$is_stream = 0;//是否以流式接口的形式返回数据,默认false。
$cacheKey = $user_id.'@chatlog';// 缓存文件名
$old_content = cache($cacheKey);
include_once CMF_ROOT . 'vendor/baidubce/Chat.php';
$chat = new Chat('ClientId','ClientSecret');//自行更改一下配置
$messages = [];
$my_msg = [];
$my_msg['role'] = 'user';
$my_msg['content'] = $msg;
if (!$old_content) {
// 之前该用户没有存在聊天记录
$messages['messages'][] = $my_msg;
} else {
// 之前有聊天记录
$messages = json_decode($old_content,true);
$messages['messages'][] = $my_msg;
}
$messages['stream'] = $is_stream == 1 ? true : false;
$data = json_encode($messages,JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);
$response = $chat->runErnieBotTurbo($data);
$res = [];
if ($is_stream == 1) {
$str_arr = explode("data: ",$response);
array_shift($str_arr);
$res_msg = [];
for ($i=0; $i < count($str_arr); $i++) {
$arr = [];
$arr = json_decode($str_arr[$i],true);
$res_msg[] = $arr['result'];
}
$res['result'] = implode("\n\n",$res_msg);
} else {
$res = json_decode($response,true);
}
$assistant_msg = [];
$assistant_msg['role'] = 'assistant';
$assistant_msg['content'] = $res['result'];
$messages['messages'][] = $assistant_msg;
cache($cacheKey,json_encode($messages));
$this->success('请求成功!',$messages);
}
多轮的需要在请求参数中将之前发送与返回的数据也加上,上面的代码示例是用的多轮,不过推荐大家使用单轮响应的方式。
最开始对接的时候,提示以下错误信息:(无权限访问该用户数据。)
{"error_code":6,"error_msg":"No permission to access data"}
首先这种问题需要考虑创建应用是否勾选相关接口权限。
