wechaty接入腾讯聊天机器人

By minirplus on 2021-10-05 in DEV

wechaty可以接入腾讯自己的聊天机器人api，来实现消息自动回复。腾讯聊天机器人业务在自然语言处理》对话机器人》闲聊下。

这里以自建的get方式php api为示例，

1	composer require tencentcloud/tencentcloud-sdk-php

api.php

<?php

require_once 'vendor/autoload.php';

use TencentCloud\Common\Credential;

use TencentCloud\Common\Profile\ClientProfile;

use TencentCloud\Common\Profile\HttpProfile;

use TencentCloud\Common\Exception\TencentCloudSDKException;

use TencentCloud\Nlp\V20190408\NlpClient;

use TencentCloud\Nlp\V20190408\Models\ChatBotRequest;

//input

if (isset($_GET['send'])) {

$send = $_GET['send'];

}

else {

die();

}

try {

$cred = new Credential("SecretId-change-it", "SecretKey-change-it");

$httpProfile = new HttpProfile();

$httpProfile->setEndpoint("nlp.tencentcloudapi.com");

$clientProfile = new ClientProfile();

$clientProfile->setHttpProfile($httpProfile);

$client = new NlpClient($cred, "ap-guangzhou", $clientProfile);

$req = new ChatBotRequest();

$params = array(

"Query" => "$send"

);

$req->fromJsonString(json_encode($params));

$resp = $client->ChatBot($req);

print_r($resp->toJsonString());

}

catch(TencentCloudSDKException $e) {

echo $e;

}

bot.js

if (msg.type() == bot.Message.Type.Text) {

// tencent chatbot

await axios.get(`https://your-api-server-address-change-me/api.php?send=${encodeURIComponent(msg.text())}`)

.then(res=>{

console.log(res.data)

global.autoReplySay = res.data.Reply

if(res.data.Confidence < 0.5){

global.autoReplySay = "..."

}

})

}

await msg.say(global.autoReplySay)

}

这里实在不知道如何把.then的值带到外面，所以用了global变量。Confidence应该是回复的匹配指数，可以用这个值来判断是否要丢弃这次的回复内容，这里设定判断阈值为0.5。注意替换上方的msg为你自己的message实例对象名称。另外需要用到axios模块 import axios from 'axios' 。

腾讯chatbot的返回内容格式

{

Reply: '不是姑姑我不明白，这世界变化快',

Confidence: 0,

RequestId: 'fac765f1-580f-401d-b8db-f65f1a544df2'

}
