最近我在给客户开发科大讯飞的星火认知大模型SparkDesk,踩过一些坑,网上几乎搜不到PHP的demo代码,这里模板兔给出以下成果代码供大家参考。
首先,sparkdesk的接口需要使用到websocket,所以我们需要先安装websocket,使用composer在网站根目录安装:
composer require textalk/websocket
然后就是写php代码:
<?php require __DIR__.'/vendor/autoload.php'; use WebSocket\Client; class api { /** * 调用科大讯飞星火认知模型 * @param $params * @return array */ public function sendMsg($params) { $prompt = $params['prompt']; //获取科大讯飞参数 $app_id = $params['APPID']; $api_key = $params['APIKEY']; $api_secret = $params['APISecret']; //拼接链接 $url = $this->createUrl($api_key, $api_secret); $client = new Client($url); //拼接要发送的信息 $message = $this->createMsg($app_id, $prompt); try { $client->send(json_encode($message, true)); $response = $client->receive(); $response_arr = json_decode($response, true); // 科达讯飞会分多次发送消息 do { if ($response_arr['header']['code'] == '0') { echo 'data: '.$response."\n\n"; //转成EventSource的输出格式 }else{ echo '[error]'.$response_arr['header']['message']; break; } $content = $response_arr['payload']['choices']['text'][0]['content']; if ($response_arr['header']['status'] == 2) { echo 'data: [DONE]'."\n\n"; break; } //继续接收消息 $response = $client->receive(); $response_arr = json_decode($response, true); } while (true); /*return [ 'code' => 0, 'msg' => '输出成功', ];*/ } catch (Exception $e) { /*return [ 'code' => -1, 'msg' => $e->getMessage(), ];*/ } finally { $client->close(); } } /** * 拼接签名 * @param $api_key * @param $api_secret * @param $time * @return string */ private function sign($api_key, $api_secret, $time) { $signature_origin = 'host: spark-api.xf-yun.com' . "\n"; $signature_origin .= 'date: ' . $time . "\n"; $signature_origin .= 'GET /v1.1/chat HTTP/1.1'; $signature_sha = hash_hmac('sha256', $signature_origin, $api_secret, true); $signature_sha = base64_encode($signature_sha); $authorization_origin = 'api_key="' . $api_key . '", algorithm="hmac-sha256", '; $authorization_origin .= 'headers="host date request-line", signature="' . $signature_sha . '"'; $authorization = base64_encode($authorization_origin); return $authorization; } /** * 生成Url * @param $api_key * @param $api_secret * @return string */ private function createUrl($api_key, $api_secret) { $url = 'wss://spark-api.xf-yun.com/v1.1/chat'; $time = gmdate('D, d M Y H:i:s') . ' GMT'; $authorization = $this->sign($api_key, $api_secret, $time); $url .= '?' . 'authorization=' . $authorization . '&date=' . urlencode($time) . '&host=spark-api.xf-yun.com'; return $url; } /** * 生成要发送的消息体 * @param $app_id * @param $speed * @param $volume * @param $pitch * @param $audio_content * @return array */ private function createMsg($app_id, $prompt) { return [ 'header' => [ 'app_id' => $app_id, ], 'parameter' => [ "chat"=> [ "domain"=> "general", "temperature"=> 0.5, "max_tokens"=> 1000, ] ], 'payload' => [ "message"=> [ "text"=> [ ["role"=> "user", "content"=> $prompt] ] ] ], ]; } } header("Content-Type: text/event-stream"); header("Cache-Control: no-cache"); header("X-Accel-Buffering: no"); header('Connection: keep-alive'); $params = array( "prompt"=>"你好", "APPID"=>"", "APIKEY"=>"", "APISecret"=>"" ); $test = new api(); $test->sendMsg($params);
我把接口输出的流转成EventSource的输出格式,这样客户端方便对接,毕竟之前对接过GPT,这样来讲切换会更容易些。
最后我们再通过客户端js来输出数据,js代码这里就不多赘述了。文章来源:https://www.toymoban.com/news/detail-688374.html
