最近在开发一个微信小微商户项目,API请求都需要携带微信的CA证书进行请求,直接上代码,就当自己备份一下

private function wx_httpPost($url, $data, $cert, $key, $headers = 0) {
    $ip = rand(0, 255) . '.' . rand(0, 255) . '.' . rand(0, 255) . '.' . rand(0, 255);
    $UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; .NET CLR 3.5.21022; .NET CLR 1.0.3705; .NET CLR 1.1.4322)";
    if (!$headers) {
        $headers = ['X-FORWARDED-FOR:' . $ip . '', 'CLIENT-IP:' . $ip . ''];
    }
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_TIMEOUT, 300);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_USERAGENT, $UserAgent);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSLCERTTYPE, 'PEM');
    curl_setopt($ch, CURLOPT_SSLCERT, $cert);
    curl_setopt($ch, CURLOPT_SSLKEYTYPE, 'PEM');
    curl_setopt($ch, CURLOPT_SSLKEY, $key);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}
