PHP-微信提现到零钱

PHP-微信提现到零钱
哈喽大家好，在原来做的微信支付的各种接口里总会不经意的就踩个地雷，虽然都是小问题，但是还是会浪费一些时间，于是乎，今儿个心血来潮就写一个关于微信提现到零钱【俗称企业付款到零钱】互相探讨，大佬轻喷哈

一．使用条件

切记切记不要在用到提现的时候再去开通

二：程序
先做一个调用支付的类
class WxpayService
{
protected $mchid;
protected $appid;
protected $appKey;
protected $apiKey;
public $data = null;

public function __construct($mchid, $appid, $appKey,$key)
{
$this->mchid = $mchid;
$this->appid = $appid;
$this->appKey = $appKey;
$this->apiKey = $key;
}

获取OpenId，用于后续的给对应的用户进行提现
/**

• 通过跳转获取用户的openid，跳转流程如下：
• 1、设置自己需要调回的url及其其他参数，跳转到微信服务器https://open.weixin.qq.com/connect/oauth2/authorize
• 2、微信服务处理完成之后会跳转回用户redirect_uri地址，此时会带上一些参数，如：code
• @return 用户的openid
  */
  public function GetOpenid()
  {
  //通过code获得openid
  if (!isset($_GET[‘code’])){
  //触发微信返回code码
  $scheme = $_SERVER[‘HTTPS’]==‘on’ ? ‘https://’ : ‘http://’;
  $baseUrl=urlencode($scheme.${}_{S}ERVER{[}^{\prime }HTT{P}_{H}OS{T}^{\prime }].$_SERVER[‘PHP_SELF’].$_SERVER[‘QUERY_STRING’]);
  $url = KaTeX parse error: Expected group after '_' at position 7: this->_̲_CreateOauthUrl…baseUrl);
  Header(“Location: $url”);
  exit();
  } else {
  //获取code码，以获取openid
  $code = $_GET[‘code’];
  $openid = $this->getOpenidFromMp($code);
  return $openid;
  }
  }

/**

• 通过code从工作平台获取openid机器access_token
• @param string $code 微信跳转回来带上的code
• @return openid
  /
  public function GetOpenidFromMp($code)
  {
  $url = KaTeX parse error: Expected group after '_' at position 7: this->_̲_CreateOauthUrl…code);
  $res=self::curlGet($url);
  //取出openid
  $data=jso{n}_{d}ecode($res,true);
  $this->data = $data;
  $openid = $data[‘openid’];
  return $openid;
  }
  /*
• 构造获取open和access_toke的url地址
• @param string $code，微信跳转带回的code
• @return 请求的url
  */
  private function __CreateOauthUrlForOpenid($code)
  {
  $urlObj[“appid”] = $this->appid;
  $urlObj[“secret”] = $this->appKey;
  $urlObj[“code”] = $code;
  $urlObj[“grant_type”] = “authorization_code”;
  $bizString = $this->ToUrlParams($urlObj);
  return "https://api.weixin.qq.com/sns/oauth2/access_token?".$bizString;
  }

/**

• 构造获取code的url连接
• @param string $redirectUrl 微信服务器回跳的url，需要url编码
• @return 返回构造好的url
  */
  private function __CreateOauthUrlForCode($redirectUrl)
  {
  $urlObj[“appid”] = $this->appid;
  $urlObj["redirec{t}_{u}ri"]="$redirectUrl";
  $urlObj[“response_type”] = “code”;
  $urlObj[“scope”] = “snsapi_base”;
  $urlObj[“state”] = “STATE”."#wechat_redirect";
  $bizString = $this->ToUrlParams($urlObj);
  return "https://open.weixin.qq.com/connect/oauth2/authorize?".$bizString;
  }

/**

• 拼接签名字符串
• @param array $urlObj
• @return 返回已经拼接好的字符串
  */
  private function ToUrlParams($urlObj)
  {
  $buff="";foreach($urlObj as $k => KaTeX parse error: Expected '}', got 'EOF' at end of input: v) { if(k != “sign”) $buff .= $k . “=” . $v . “&”;
  }
  $buff=trim($buff, “&”);
  return $buff;
  }

进行付款，将获取的openId与其他参数代入这个方法
/**

• 企业付款
• @param string $openid 调用【网页授权获取用户信息】接口获取到用户在该公众号下的Openid
• @param float $totalFee 收款总费用 单位元
• @param string $outTradeNo 唯一的订单号
• @param string $orderName 订单名称
• @param string $notifyUrl 支付结果通知url 不要有问号
• @param string $timestamp 支付时间
• @return string
  */
  public function createJsBizPackage($openid, $totalFee, $outTradeNo,$trueName)
  {
  $config = array(
  ‘mch_id’ => $this->mchid,
  ‘appid’ => $this->appid,
  ‘key’ => $this->apiKey,
  );
  $unified = array(
  ‘mch_appid’ => $config[‘appid’],
  ‘mchid’ => $config[‘mch_id’],
  ‘nonce_str’ => self::createNonceStr(),
  ‘openid’ => $openid{,}^{\prime }chec{k}_{n}am{e}^{\prime }={>}^{\prime }FORC{E}_{C}HEC{K}^{\prime },//校验用户姓名选项。N{O}_{C}HECK：不校验真实姓名，FORC{E}_{C}HECK：强校验真实姓{名}^{\prime }r{e}_{u}se{r}_{n}am{e}^{\prime }=>$trueName, //收款用户真实姓名（不支持给非实名用户打款）
  ‘partner_trade_no’ => $outTradeNo{,}^{\prime }spbil{l}_{c}reat{e}_i{p}^{\prime }={>}^{\prime }127.0.0.1^{\prime }{,}^{\prime }amoun{t}^{\prime }=>intval($totalFee * 100), //单位 转为分
  ‘desc’=>‘付款’, //企业付款操作说明信息
  );
  $unified{[}^{\prime }sig{n}^{\prime }]=self::getSign($unified, $config[‘key’]);
  $responseXml = $this->curlPost{(}^{\prime }https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfer{s}^{\prime },self::arrayToXml($unified));
  $unifiedOrder=simplexm{l}_{l}oa{d}_{s}tring($responseXml, ‘SimpleXMLElement’, LIBXML_NOCDATA);
  if ($unifiedOrder===false)die{(}^{\prime }parsexmlerro{r}^{\prime });if($unifiedOrder->return_code != ‘SUCCESS’) {
  die(KaTeX parse error: Expected 'EOF', got '}' at position 30: …return_msg); }̲ if (unifiedOrder->result_code != ‘SUCCESS’) {
  die($unifiedOrder->err_code);
  }
  return true;
  }

public static function curlGet($url = ‘’, $options = array())
{
$ch=cur{l}_{i}nit($url);
curl_setopt($ch,CURLOP{T}_{R}ETURNTRANSFER,1);cur{l}_{s}etopt($ch, CURLOPT_TIMEOUT, 30);

}

这里去拿自己在商户号中拿到的证书，要注意的是，php拿到的是以.pem结尾的证书
public function curlPost($url = ‘’, $postData = ‘’, KaTeX parse error: Expected '}', got 'EOF' at end of input: … if (is_array(postData)) {
$postData=htt{p}_{b}uil{d}_{q}uery($postData);
}
$ch=cur{l}_{i}nit();cur{l}_{s}etopt($ch, CURLOPT_URL, $url);cur{l}_{s}etopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,CURLOP{T}_{P}OST,1);cur{l}_{s}etopt($ch, CURLOPT_POSTFIELDS, $postData);cur{l}_{s}etopt($ch, CURLOPT_TIMEOUT, 30); //设置cURL允许执行的最长秒数
if (!empty(KaTeX parse error: Expected '}', got 'EOF' at end of input: …l_setopt_array(ch, KaTeX parse error: Expected 'EOF', got '}' at position 13: options); }̲ //https请求 不验…ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

 //第一种方法，cert 与 key 分别属于两个.pem文件
 //默认格式为PEM，可以注释
 curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM');
 curl_setopt($ch,CURLOPT_SSLCERT,getcwd().'/cert/apiclient_cert.pem');
 //默认格式为PEM，可以注释
 curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM');
 curl_setopt($ch,CURLOPT_SSLKEY,getcwd().'/cert/apiclient_key.pem');
 //第二种方式，两个文件合成一个.pem文件
// curl_setopt($ch,CURLOPT_SSLCERT,getcwd().'/all.pem');
 $data = curl_exec($ch);
 curl_close($ch);
 return $data;

}

public static function createNonceStr($length = 16)
{
$chars = ‘abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789’;
$str{=}^{\prime \prime };for($i = 0; $i < $length; $i++) {
$str.=substr($chars, mt_rand(0, strlen($chars) - 1), 1);
}
return KaTeX parse error: Expected 'EOF', got '}' at position 7: str; }̲ public static…arr)
{
$xml="";foreach($arr as $key => KaTeX parse error: Expected '}', got 'EOF' at end of input: …if (is_numeric(val)) {
$xml .= “<” . $key . “>” . $val . “”;
} else
$xml .= “<” . $key . “>”;
}
$xml .= “”;
return $xml;
}

public static function getSign($params, KaTeX parse error: Expected '}', got 'EOF' at end of input: …ey) { ksort(params, SORT_STRING);

调取类文件进行提现

至此，大功告成~~~~~~ ~~~~~~
