首先給大家看一看這個(gè)表格：

php編程（視頻）根據(jù)微信高級(jí)紅包接口，開(kāi)發(fā)PHP版本的API接口，現(xiàn)在進(jìn)行主要代碼分析。
紅包接口調(diào)用請(qǐng)求代碼，所有請(qǐng)求參數(shù)為必填參數(shù)與文檔對(duì)應(yīng)：
class Wxapi {
private $app_id = '
wxXXXXXXXXXXXX'
;
//公眾賬號(hào)appid，首先申請(qǐng)與之配套的公眾賬號(hào) private $app_secret = '
XXXXXXXXXXXXXXXXXXXXXXXX'
;
//公眾號(hào)secret，用戶獲取用戶授權(quán)token private $app_mchid = '
XXXXXXXX'
;
//商戶號(hào)id function __construct(){
//do sth here.... }
/** * 微信支付 * @param string $openid 用戶openid */ public function pay($re_openid) {
include_once('
WxHongBaoHelper.php'
);
$commonUtil = new CommonUtil();
$wxHongBaoHelper = new WxHongBaoHelper();
$wxHongBaoHelper->setParameter("nonce_str", $this->great_rand());
//隨機(jī)字符串，丌長(zhǎng)于 32 位 $wxHongBaoHelper->setParameter("mch_billno", $this->app_mchid.date('
YmdHis'
).rand(1000, 9999));
//訂單號(hào) $wxHongBaoHelper->setParameter("mch_id", $this->app_mchid);
//商戶號(hào) $wxHongBaoHelper->setParameter("wxappid", $this->app_id);
$wxHongBaoHelper->setParameter("nick_name", '
紅包'
);
//提供方名稱 $wxHongBaoHelper->setParameter("send_name", '
紅包'
);
//紅包發(fā)送者名稱 $wxHongBaoHelper->setParameter("re_openid", $re_openid);
//相對(duì)于醫(yī)脈互通的openid $wxHongBaoHelper->setParameter("total_amount", 100);
//付款金額，單位分 $wxHongBaoHelper->setParameter("min_value", 100);
//最小紅包金額，單位分 $wxHongBaoHelper->setParameter("max_value", 100);
//最大紅包金額，單位分 $wxHongBaoHelper->setParameter("total_num", 1);
//紅包収放總?cè)藬?shù) $wxHongBaoHelper->setParameter("wishing", '
感謝您參與紅包派發(fā)活動(dòng)，祝您新年快樂(lè)！'
);
//紅包祝福詫 $wxHongBaoHelper->setParameter("client_ip", '
127.0.0.1'
);
//調(diào)用接口的機(jī)器 Ip 地址 $wxHongBaoHelper->setParameter("act_name", '
紅包活動(dòng)'
);
//活勱名稱 $wxHongBaoHelper->setParameter("remark", '
快來(lái)?yè)專?
);
//備注信息 $postXml = $wxHongBaoHelper->create_hongbao_xml();
$url = '
https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack'
;
$responseXml = $wxHongBaoHelper->curl_post_ssl($url, $postXml);
//用作結(jié)果調(diào)試輸出 //echo htmlentities($responseXml,ENT_COMPAT,'
UTF-8'
);
$responseObj = simplexml_load_string($responseXml, '
SimpleXMLElement'
, LIBXML_NOCDATA);
return $responseObj->return_code;
}
獲取隨機(jī)字符串方法：
/** * 生成隨機(jī)數(shù) */ public function great_rand(){
$str = '
1234567890abcdefghijklmnopqrstuvwxyz'
;
for($i=0;
$i$i++){
$j=rand(0,35);
$t1 .= $str[$j];
}
return $t1;
}
簽名算法：
/** 例如：
appid：
wxd111665abv58f4f mch_id：
10000100 device_info：
1000 Body：
test nonce_str：
ibuaiVcKdpRxkhJA 第一步：
對(duì)參數(shù)按照 key=value 的格式，并按照參數(shù)名 ASCII 字典序排序如下：
stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_i d=10000100&nonce_str=ibuaiVcKdpRxkhJA";
第二步：
拼接支付密鑰：
stringSignTemp="stringA&key=192006250b4c09247ec02edce69f6a2d" sign=MD5(stringSignTemp).toUpperCase()="9A0A8659F005D6984697E2CA0A 9CF3B7" */ protected function get_sign(){
define('
PARTNERKEY'
,"QSRXXXXXXXXXXXXXXXXXXXXX");
try {
if (null == PARTNERKEY || "" == PARTNERKEY ) {
throw new SDKRuntimeException("密鑰不能為空！" . "
");
}
if($this->check_sign_parameters() == false) {
//檢查生成簽名參數(shù) throw new SDKRuntimeException("生成簽名參數(shù)缺失！" . "
");
}
$commonUtil = new CommonUtil();
ksort($this->parameters);
$unSignParaString = $commonUtil->formatQueryParaMap($this->parameters, false);
$md5SignUtil = new MD5SignUtil();
return $md5SignUtil->sign($unSignParaString,$commonUtil->trimString(PARTNERKEY));
}
catch (SDKRuntimeException $e) {
die($e->errorMessage());
}
}
CURL請(qǐng)求以及發(fā)送證書：
function curl_post_ssl($url, $vars, $second=30,$aHeader=array()) {
$ch = curl_init();
//超時(shí)時(shí)間 curl_setopt($ch,CURLOPT_TIMEOUT,$second);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
//這里設(shè)置代理，如果有的話 curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);
//cert 與 key 分別屬于兩個(gè).pem文件 //請(qǐng)確保您的libcurl版本是否支持雙向認(rèn)證，版本高于7.20.1 curl_setopt($ch,CURLOPT_SSLCERT,dirname(__FILE__).DIRECTORY_SEPARATOR.'
zhengshu'
.DIRECTORY_SEPARATOR.'
apiclient_cert.pem'
);
curl_setopt($ch,CURLOPT_SSLKEY,dirname(__FILE__).DIRECTORY_SEPARATOR.'
zhengshu'
.DIRECTORY_SEPARATOR.'
apiclient_key.pem'
);
curl_setopt($ch,CURLOPT_CAINFO,dirname(__FILE__).DIRECTORY_SEPARATOR.'
zhengshu'
.DIRECTORY_SEPARATOR.'
rootca.pem'
);
if( count($aHeader) >= 1 ){
curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);
}
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$vars);
$data = curl_exec($ch);
if($data){
curl_close($ch);
return $data;
}
else {
$error = curl_errno($ch);
//echo "call faild, errorCode:$error ";
curl_close($ch);
return false;
}
}
入口文件：
@require "pay.php";
//獲取用戶信息 $get = $_GET['
param'
];
$code = $_GET['
code'
];
//判斷code是否存在 if($get=='
access_token'
&& !empty($code)){
$param['
param'
] = '
access_token'
;
$param['
code'
] = $code;
$packet = new Packet();
//獲取用戶openid信息 $userinfo = $packet->_route('
userinfo'
,$param);
if(empty($userinfo['
openid'
])){
exit("NOAUTH");
}
//調(diào)取支付方法 $packet->_route('
wxpacket'
,array('
openid'
=>$userinfo['
openid'
]));
}
else{
$packet->_route('
userinfo'
);
}
