我来介绍PHP项目中调用文本摘要接口的几种常见方法：
使用cURL调用API接口
百度AI接口示例
<?php
function textSummary($text, $apiKey, $secretKey) {
$url = "https://aip.baidubce.com/rpc/2.0/nlp/v1/news_summary";
// 获取access_token
$tokenUrl = "https://aip.baidubce.com/oauth/2.0/token";
$postData = [
'grant_type' => 'client_credentials',
'client_id' => $apiKey,
'client_secret' => $secretKey
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $tokenUrl);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
$tokenInfo = json_decode($response, true);
$accessToken = $tokenInfo['access_token'];
// 调用文本摘要接口
$data = [
'content' => $text,
'max_summary_len' => 200
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url . "?access_token=" . $accessToken);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
return json_decode($result, true);
}
// 使用示例
$text = "这里是需要生成摘要的长文本内容...";
$apiKey = "your_api_key";
$secretKey = "your_secret_key";
$summary = textSummary($text, $apiKey, $secretKey);
print_r($summary);
?>
通用API调用封装函数
<?php
function callSummaryAPI($text, $apiUrl, $apiKey, $maxLength = 200) {
$data = [
'text' => $text,
'max_length' => $maxLength,
'min_length' => 50
];
$headers = [
'Authorization: Bearer ' . $apiKey,
'Content-Type: application/json'
];
$ch = curl_init();
curl_setopt_array($ch, [
CURLOPT_URL => $apiUrl,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => json_encode($data),
CURLOPT_HTTPHEADER => $headers,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_TIMEOUT => 30,
CURLOPT_SSL_VERIFYPEER => false
]);
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($httpCode == 200) {
return json_decode($response, true);
} else {
return ['error' => 'API调用失败', 'code' => $httpCode];
}
}
?>
使用Guzzle HTTP客户端
<?php
require 'vendor/autoload.php';
use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;
class TextSummarizer {
private $client;
private $apiKey;
private $apiUrl;
public function __construct($apiKey, $apiUrl) {
$this->client = new Client();
$this->apiKey = $apiKey;
$this->apiUrl = $apiUrl;
}
public function summarize($text, $options = []) {
try {
$response = $this->client->post($this->apiUrl, [
'headers' => [
'Authorization' => 'Bearer ' . $this->apiKey,
'Content-Type' => 'application/json',
],
'json' => array_merge([
'text' => $text,
'max_length' => 200,
'min_length' => 50,
], $options),
'timeout' => 30,
]);
return json_decode($response->getBody(), true);
} catch (RequestException $e) {
return [
'error' => true,
'message' => $e->getMessage()
];
}
}
}
// 使用示例
$summarizer = new TextSummarizer(
'your_api_key',
'https://api.example.com/summarize'
);
$result = $summarizer->summarize('这里是需要摘要的文本内容...');
echo $result['summary'];
?>
常用API示例
阿里云NLP接口
<?php
function aliyunTextSummary($text, $accessKeyId, $accessKeySecret) {
require_once 'aliyun-php-sdk-core/Config.php';
$client = new DefaultAcsClient(
'cn-hangzhou',
$accessKeyId,
$accessKeySecret
);
$request = new Aliyun\Api\Nlp\Request\V20180408\TextSummaryRequest();
$request->setAcceptFormat('JSON');
$request->setTitle("文章标题");
$request->setContent($text);
$request->setSummaryLength(200);
try {
$response = $client->getAcsResponse($request);
return json_decode(json_encode($response), true);
} catch (Exception $e) {
return ['error' => $e->getMessage()];
}
}
?>
OpenAI GPT API
<?php
function openAISummary($text, $apiKey) {
$url = "https://api.openai.com/v1/chat/completions";
$data = [
'model' => 'gpt-3.5-turbo',
'messages' => [
[
'role' => 'system',
'content' => '请对以下文本生成简洁的摘要，不超过100字：'
],
[
'role' => 'user',
'content' => $text
]
],
'max_tokens' => 200,
'temperature' => 0.5
];
$ch = curl_init();
curl_setopt_array($ch, [
CURLOPT_URL => $url,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => json_encode($data),
CURLOPT_HTTPHEADER => [
'Authorization: Bearer ' . $apiKey,
'Content-Type: application/json'
],
CURLOPT_RETURNTRANSFER => true
]);
$response = curl_exec($ch);
curl_close($ch);
return json_decode($response, true);
}
?>
完整的调用示例类
<?php
class TextSummaryService {
private $provider;
private $config;
public function __construct($provider = 'baidu', $config = []) {
$this->provider = $provider;
$this->config = $config;
}
public function generate($text, $options = []) {
switch ($this->provider) {
case 'baidu':
return $this->baiduSummary($text, $options);
case 'aliyun':
return $this->aliyunSummary($text, $options);
case 'openai':
return $this->openAISummary($text, $options);
default:
throw new Exception("不支持的API提供商");
}
}
private function baiduSummary($text, $options) {
// 百度API实现
$apiKey = $this->config['api_key'] ?? '';
$secretKey = $this->config['secret_key'] ?? '';
return textSummary($text, $apiKey, $secretKey);
}
private function aliyunSummary($text, $options) {
// 阿里云API实现
$accessKeyId = $this->config['access_key_id'] ?? '';
$accessKeySecret = $this->config['access_key_secret'] ?? '';
return aliyunTextSummary($text, $accessKeyId, $accessKeySecret);
}
private function openAISummary($text, $options) {
// OpenAI API实现
$apiKey = $this->config['api_key'] ?? '';
return openAISummary($text, $apiKey);
}
}
// 使用示例
$config = [
'api_key' => 'your_api_key',
'secret_key' => 'your_secret_key'
];
$summaryService = new TextSummaryService('baidu', $config);
$result = $summaryService->generate('需要摘要的文本内容...');
?>
注意事项
- API密钥保护：密钥不要直接写在代码中，建议使用环境变量或配置文件
- 错误处理：添加完善的异常捕获和错误处理机制
- 文本长度限制：注意API的文本长度限制，超长文本需要分段处理
- 频率限制：了解API的调用频率限制，避免被限流
- 缓存机制：对相同内容的摘要可以缓存，减少API调用
需要我详细解释某个特定API的调用方法吗？
