当将Java代码转换为PHP代码时,需要注意一些语法和函数的差异。下面是将给定的Java代码转换为PHP代码的示例:
```php
function sign($map, $privateKey) {
// 将计算签名内容按照规则生成签名字符串:去除空值,按照ASCII码排序,将属性和值使用=连接,最后使用&连接各个拼接的字符串
$signSource = implode('&', array_map(
function ($key, $value) {
return $key . '=' . $value;
},
array_keys($map),
array_values($map)
));
// 进行签名
try {
// 根据私钥字符串生成私钥
$rsaKey = openssl_pkey_get_private(base64_decode($privateKey));
// 新建Signature对象,用于签名/验签
$signature = '';
// Signature对象初始化签名
openssl_sign($signSource,***

以下是使用 PHP 和 cURL 请求实现的代码:
```php
<?php
class AdApi {
private $key;
private $client;
private $url;
public function __construct($key) {
$netTransport = [
'DialContext' => (new \GuzzleHttp\Client())->getConfig('timeout'),
'TLSHandshakeTimeout' => 1,
'ResponseHeaderTimeout' => 3,
'ExpectContinueTimeout' => 1,
'MaxIdleConnsPerHost' => 10,
'MaxIdleConns' => 100,
'IdleConnTimeout' => 10,
];
$netClient = [
'timeout' => 30,
'transport' => $netTransport,
];
$this->key = $key;
$this->client = new \GuzzleHttp\Client($netClient);
$this->url = 'http://adapi.ysjgames.com/';
}
public function accounts() {
$params = [
'mod' => 'ad',
'type' => 'accounts',
];
$this->injectSign($params);
$accountUrl = $this->url . '?' . http_build_query($params);
$response = $this->client->get($accountUrl);
if ($response->getStatusCode() !== 200) {
throw new Exception('Request failed with status code ' . $response->getStatusCode());
}
$body = (string) $response->getBody();
$respData = json_decode($body, true);
if ($respData['code'] !== 0) {
throw new Exception('code != 0 :' . $body);
}
return $respData['accounts'];
}
private function injectSign(&$params) {
$current = time();
$sign = md5($current . $this->key);
$params['time'] = $current;
$params['sign'] = $sign;
}
}
// Usage example
$adApi = new AdApi('aasd@##SDfsd1213');
try {
$accounts = $adApi->accounts();
var_dump($accounts);
} catch (Exception $e) {
echo $e->getMessage();
}
```
在上面的代码中,我们使用了 Guzzle HTTP 扩展来创建 HTTP 客户端,而不是原始的 cURL 函数。这是因为 Guzzle 提供了更好的 API,可以更方便地处理请求和响应。我们在构造函数中配置了一个 `GuzzleHttp\Client` 实例,该实例使用与 Go 代码中相同的参数来配置 cURL。我们还使用了 `http_build_query` 函数来构建查询字符串,并将签名参数注入到参数数组中,就像 Go 代码中的 `InjectSign` 方法一样。最后,我们使用 `json_decode` 函数来解析响应正文,并使用 `var_dump` 函数输出返回的帐户列表。
签名验证java代码示例
以下是一个使用Java进行微信支付签名验证的示例代码:
```java
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.*;
public class WeChatPaySignatureValidator {
// 商户密钥(API密钥)
private static final String API_KEY = "your_api_key";
public static boolean validateSignature(Map<String, String> params) {
// 将参数按照键值对的字典序排序
SortedMap<String, String> sortedParams = new TreeMap<>(params);
// 拼接待验证的签名字符串
StringBuilder sb = new StringBuilder();
for (Map.Entry<String, String> entry : sortedParams.entrySet()) {
String key = entry.getKey();
String value = entry.getValue();
if (value != null && !value.isEmpty() && !"sign".equals(key)) {
sb.append(key).append("=").append(value).append("&");
}
}
sb.append("key=").append(API_KEY);
// 使用MD5算法进行加密,生成签名值
String sign = md5(sb.toString()).toUpperCase();
// 验证签名
return sign.equals(params.get("sign"));
}
private static String md5(String s) {
try {
MessageDigest md = MessageDigest.getInstance("MD5");
byte[] bytes = md.digest(s.getBytes());
StringBuilder result = new StringBuilder();
for (byte b : bytes) {
String hex = Integer.toHexString(b & 0xff);
if (hex.length() == 1) {
result.append("0");
}
result.append(hex);
}
return result.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
return null;
}
}
}
```
使用示例:
```java
public class Main {
public static void main(String[] args) {
// 假设收到的回调参数存储在一个Map中
Map<String, String> params = new HashMap<>();
params.put("appid", "your_appid");
params.put("mch_id", "your_mch_id");
params.put("nonce_str", "random_nonce_str");
params.put("out_trade_no", "your_order_no");
params.put("sign", "generated_sign");
boolean isValid = WeChatPaySignatureValidator.validateSignature(params);
if (isValid) {
System.out.println("签名验证通过");
// TODO: 处理支付回调逻辑
} else {
System.out.println("签名验证失败");
// TODO: 处理异常情况
}
}
}
```
请注意,上述示例代码仅提供了签名验证的基本逻辑,您需要根据具体的业务需求和微信支付接口文档进行相应的参数处理和异常处理。此外,确保您已正确获取并保存了商户密钥(API密钥),并在代码中进行相应的替换。
