php实现微信公众号企业转账功能

微信(小程序)  /  管理员 发布于 7年前   162

企业付款提供由商户直接付钱至用户微信零钱的能力，支持平台操作及接口调用两种方式，资金到账速度快，使用及查询方便。主要用来解决合理的商户对用户付款需求，比如：保险理赔、彩票兑换等等。

特点

• 发起方式灵活，可通过页面或接口发起
• 微信消息触达，用户及时获知入账详情
• 支持实名校验，判断收款人真实身份
• 通过openid即可实现付款，无需用户敏感隐私信息
• 到账速度快，在发起后，用户可在几分钟内收到付款

企业转账需要到微信商户平台=》产品中心=》企业付款到零钱，开启此功能

下面是程序截图：

第一步：设置配置参数

$url='https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers';$pars = array();$pars['mch_appid'] =$this->module['config']['appid'];$pars['mchid']=$this->module['config']['mchid'];$pars['nonce_str'] =random(32);$pars['partner_trade_no'] =time().random(3,1);$pars['openid'] =$openid;$pars['check_name'] ='NO_CHECK' ;//$pars['re_user_name'] ='' ;$monet_finall = $price * 100;$pars['amount'] =$monet_finall; //这里是折算成1%的所以要*100$pars['desc'] ='您已成功提现 '.$price.' 现金';$pars['spbill_create_ip'] =$this->module['config']['ip'];ksort($pars, SORT_STRING);$string1 = '';foreach ($pars as $k => $v) {  $string1 .= "{$k}={$v}&";}$string1 .= "key=".$this->module['config']['password'];$pars['sign'] = strtoupper(md5($string1));$xml = array2xml($pars);$extras = array();$extras['CURLOPT_CAINFO'] = ATTACHMENT_ROOT . '/withdraw/cert/rootca.pem.' . $_W['uniacid'];$extras['CURLOPT_SSLCERT'] = ATTACHMENT_ROOT   . '/withdraw/cert/apiclient_cert.pem.' . $_W['uniacid'];$extras['CURLOPT_SSLKEY'] = ATTACHMENT_ROOT . '/withdraw/cert/apiclient_key.pem.' . $_W['uniacid'];$procResult = null;

第二步：CURL请求微信服务器

load()->func('communication');$resp = ihttp_request($url, $xml, $extras);

其中ihttp_request函数内容是：

function ihttp_request($url, $post = '', $extra = array(), $timeout = 60) {  $urlset = parse_url($url);  if (empty($urlset['path'])) {   $urlset['path'] = '/';  }  if (!empty($urlset['query'])) {   $urlset['query'] = "?{$urlset['query']}";  }  if (empty($urlset['port'])) {     }  if (strexists($url, 'https://') && !extension_loaded('openssl')) {   if (!extension_loaded("openssl")) {     message('请开启您PHP环境的openssl');   }  }  if (function_exists('curl_init') && function_exists('curl_exec')) {   $ch = curl_init();   if (!empty($extra['ip'])) {     $extra['Host'] = $urlset['host'];     $urlset['host'] = $extra['ip'];     unset($extra['ip']);   }   curl_setopt($ch, CURLOPT_URL, $urlset['scheme'] . '://' . $urlset['host'] . ($urlset['port'] == '80' || empty($urlset['port']) ? '' : ':' . $urlset['port']) . $urlset['path'] . $urlset['query']);   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);   @curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);   curl_setopt($ch, CURLOPT_HEADER, 1);   @curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);   if ($post) {     if (is_array($post)) {      $filepost = false;foreach ($post as $name => &$value) {        if (version_compare(phpversion(), '5.6') >= 0 && substr($value, 0, 1) == '@') {         $value = new CURLFile(ltrim($value, '@'));        }        if ((is_string($value) && substr($value, 0, 1) == '@') || (class_exists('CURLFile') && $value instanceof CURLFile)) {         $filepost = true;        }      }      if (!$filepost) {        $post = http_build_query($post);      }     }     curl_setopt($ch, CURLOPT_POST, 1);     curl_setopt($ch, CURLOPT_POSTFIELDS, $post);   }   if (!empty($GLOBALS['_W']['config']['setting']['proxy'])) {     $urls = parse_url($GLOBALS['_W']['config']['setting']['proxy']['host']);     if (!empty($urls['host'])) {      curl_setopt($ch, CURLOPT_PROXY, "{$urls['host']}:{$urls['port']}");      $proxytype = 'CURLPROXY_' . strtoupper($urls['scheme']);      if (!empty($urls['scheme']) && defined($proxytype)) {        curl_setopt($ch, CURLOPT_PROXYTYPE, constant($proxytype));      } else {        curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);        curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);      }      if (!empty($GLOBALS['_W']['config']['setting']['proxy']['auth'])) {        curl_setopt($ch, CURLOPT_PROXYUSERPWD, $GLOBALS['_W']['config']['setting']['proxy']['auth']);      }     }   }   curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);   curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);   curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);   curl_setopt($ch, CURLOPT_SSLVERSION, 1);   if (defined('CURL_SSLVERSION_TLSv1')) {     curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);   }   curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1');   if (!empty($extra) && is_array($extra)) {     $headers = array();     foreach ($extra as $opt => $value) {      if (strexists($opt, 'CURLOPT_')) {        curl_setopt($ch, constant($opt), $value);      } elseif (is_numeric($opt)) {        curl_setopt($ch, $opt, $value);      } else {        $headers[] = "{$opt}: {$value}";      }     }     if (!empty($headers)) {      curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);     }   }   $data = curl_exec($ch);   $status = curl_getinfo($ch);   $errno = curl_errno($ch);   $error = curl_error($ch);   curl_close($ch);   if ($errno || empty($data)) {     return error(1, $error);   } else {     return ihttp_response_parse($data);   }  }  $method = empty($post) ? 'GET' : 'POST';  $fdata = "{$method} {$urlset['path']}{$urlset['query']} HTTP/1.1\r\n";  $fdata .= "Host: {$urlset['host']}\r\n";  if (function_exists('gzdecode')) {   $fdata .= "Accept-Encoding: gzip, deflate\r\n";  }  $fdata .= "Connection: close\r\n";  if (!empty($extra) && is_array($extra)) {   foreach ($extra as $opt => $value) {     if (!strexists($opt, 'CURLOPT_')) {      $fdata .= "{$opt}: {$value}\r\n";     }   }  }  $body = '';  if ($post) {   if (is_array($post)) {     $body = http_build_query($post);   } else {     $body = urlencode($post);   }   $fdata .= 'Content-Length: ' . strlen($body) . "\r\n\r\n{$body}";  } else {   $fdata .= "\r\n";  }  if ($urlset['scheme'] == 'https') {   $fp = fsockopen('ssl://' . $urlset['host'], $urlset['port'], $errno, $error);  } else {   $fp = fsockopen($urlset['host'], $urlset['port'], $errno, $error);  }  stream_set_blocking($fp, true);  stream_set_timeout($fp, $timeout);  if (!$fp) {   return error(1, $error);  } else {   fwrite($fp, $fdata);   $content = '';   while (!feof($fp))     $content .= fgets($fp, 512);   fclose($fp);   return ihttp_response_parse($content, true);  }}

第三步：解析分析微信服务器返回值并返回。

if (is_error($resp)) {  $procResult = $resp;} else {  $arr=json_decode(json_encode((array) simplexml_load_string($resp['content'])), true);  $xml = '' . $resp['content'];  $dom = new \DOMDocument();  if ($dom->loadXML($xml)) {    $xpath = new \DOMXPath($dom);    $code = $xpath->evaluate('string(//xml/return_code)');    $ret = $xpath->evaluate('string(//xml/result_code)');    if (strtolower($code) == 'success' && strtolower($ret) == 'success') {      $procResult = array('errno'=>0,'error'=>'success');;    } else {      $error = $xpath->evaluate('string(//xml/err_code_des)');      $procResult = array('errno'=>-2,'error'=>$error);    }  } else {    $procResult = array('errno'=>-1,'error'=>'未知错误');  }}return $procResult;
