这是我第一次使用机器人。我决定使用wit.ai bot,使用PHP。我想要做的是为机器人设置回调函数,例如当用户要求天气时机器人将执行getWeather()
。如果我使用cURL
,如何将此功能传递给机器人?有可能吗?我在git上找到了一些SDK,但是对于wit.ai来说,它们都是非官方的。
$ch = curl_init();
$headr = array();
$headr[] = "Authorization: Bearer XXXXXXXXXXXXXXXX";
curl_setopt($ch, CURLOPT_URL,"https://api.wit.ai/message?v=20170118&q=what is weather in London ?");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER,$headr);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec ($ch);
curl_close ($ch);
echo $server_output;
我发现了这个SDK https://github.com/tgallice/wit-php,但我无法使用ActionMapping它总是给出错误:
致命错误:Class' ActionMapping'找不到 第12行/Users/jack/Documents/www/bar/index.php
我的代码:
<?php
require_once __DIR__.'/vendor/autoload.php';
use Tgallice\Wit\Client;
use Tgallice\Wit\ConverseApi;
use Tgallice\Wit\Conversation;
use Tgallice\Wit\Model\Step\Action;
use Tgallice\Wit\Model\Step\Message;
class MyActionMapping extends ActionMapping
{
/**
* @inheritdoc
*/
public function action($sessionId, Context $context, Action $step)
{
return call_user_func_array(array($this, $step->getAction()), array($sessionId, $context));
}
/**
* @inheritdoc
*/
public function say($sessionId, Context $context, Message $step)
{
echo $step->getMessage();
}
}
$client = new Client('XXX');
$api = new ConverseApi($client);
$actionMapping = new MyActionMapping();
$conversation = new Conversation($api, $actionMapping);
$context = $conversation->converse('session_id', 'Hello I live in London');
答案 0 :(得分:4)
根据你的错误,你确定这些事情:
安装库:
首先,通过composer安装库,以便正确添加所有文件。也许这将是主要原因。
curl中传递的参数:
对于wheater,您使用了https://wit.ai/docs/http/20160526 API。此外,令牌部分缺少卷曲
并点击此功能:
$ curl -XPOST 'https://api.wit.ai/converse?v=20160526&session_id=123abc&q=weather%20in%20Brussels' \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H 'Authorization: Bearer $TOKEN'
