用laravel对接一个文字转语音的功能列出全部代码

由于涉及到第三方API的调用,需要先申请相应的API Key。以下是对接百度AI语音合成API的示例代码:
1. 在 .env 文件中添加如下配置:
```
BAIDU_AI_APP_ID=your_app_id
BAIDU_AI_API_KEY=your_api_key
BAIDU_AI_SECRET_KEY=your_secret_key
```
2. 创建一个语音合成服务的控制器 SpeechController:
```
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
use GuzzleHttp\Client;
class SpeechController extends Controller
{
public function textToSpeech(Request $request)
{
// 获取请求参数
$text = $request->input('text');
$lang = $request->input('lang', 'zh');
$speed = $request->input('speed', 5);
// 构建请求参数
$params = [
'tex' => $text,
'lang' => $lang,
'spd' => $speed,
'cuid' => uniqid(),
'ctp' => 1,
'tok' => '',
];
// 生成签名
$params['tok'] = $this->generateToken($params);
// 发送请求
$client = new Client();
$response = $client->request('GET', 'http://tsn.baidu.com/text2audio', [
'query' => $params,
]);
// 解析响应
$contentType = $response->getHeaderLine('Content-Type');
$contentLength = $response->getHeaderLine('Content-Length');
$body = $response->getBody();
// 保存音频文件
$fileName = uniqid() . '.mp3';
Storage::put('speech/' . $fileName, $body);
// 返回音频文件URL
return Storage::url('speech/' . $fileName);
}
private function generateToken($params)
{
$appKey = env('BAIDU_AI_API_KEY');
$appSecret = env('BAIDU_AI_SECRET_KEY');
ksort($params);
$queryStr = http_build_query($params) . $appSecret;
$sign = md5($queryStr);
return "{$appKey}:{$sign}";
}
}
```
3. 在路由中定义语音合成服务的API接口:
```
Route::get('/speech', 'SpeechController@textToSpeech');
```
4. 在前端页面中调用语音合成服务的API接口:
```
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Text to Speech</title>
</head>
<body>
<textarea id="text" rows="5" cols="50"></textarea>
<select id="lang">
<option value="zh">中文</option>
<option value="en">英文</option>
</select>
<select id="speed">
<option value="1">慢速</option>
<option value="5" selected>标准速度</option>
<option value="9">快速</option>
</select>
<button id="submit">转换</button>
<audio id="audio" controls></audio>
<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script>
$(function() {
$('#submit').click(function() {
var text = $('#text').val();
var lang = $('#lang').val();
var speed = $('#speed').val();
$.get('/speech', {
text: text,
lang: lang,
speed: speed,
}, function(response) {
$('#audio').attr('src', response);
});
});
});
</script>
</body>
</html>
```
以上代码仅供参考,实际使用时需要根据业务需求进行适当修改。
