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);
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;
