php实现微信公众号企业转账功能

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,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,1) == '@') {

$value = new CURLFile(ltrim($value,'@'));

}

if ((is_string($value) && substr($value,1) == '@') || (class_exists('CURLFile') && $value instanceof CURLFile)) {

$filepost = true;

}

}

if (!$filepost) {

$post = http_build_query($post);

}

}

curl_setopt($ch,CURLOPT_POST,CURLOPT_POSTFIELDS,$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,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,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,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/1.1rn";

$fdata .= "Host: {$urlset['host']}rn";

if (function_exists('gzdecode')) {

$fdata .= "Accept-Encoding: gzip,deflatern";

}

$fdata .= "Connection: closern";

if (!empty($extra) && is_array($extra)) {

foreach ($extra as $opt => $value) {

if (!strexists($opt,'CURLOPT_')) {

$fdata .= "{$opt}: {$value}rn";

}

}

}

$body = '';

if ($post) {

if (is_array($post)) {

$body = http_build_query($post);

} else {

$body = urlencode($post);

}

$fdata .= 'Content-Length: ' . strlen($body) . "rnrn{$body}";

} else {

$fdata .= "rn";

}

if ($urlset['scheme'] == 'https') {

$fp = fsockopen('ssl://' . $urlset['host'],$urlset['port'],$errno,$error);

} else {

$fp = fsockopen($urlset['host'],$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;
