本文实例讲述了php版微信js-sdk支付接口类用法。分享给大家供大家参考，具体如下：

这个支付类是根据官方的文档修改而来！主要实现生成JS API 、Native的package签名包和Native响应的XML格式数据。注释都标上了各方法的用意。由于package包签名，略复杂，这个要自己多花时间去对应去看和log出文件来一一对比！当然只要你用上教程的类，设置好对应的参数就可以正确的生成package参数等

if (isset($argc) && $argc >= 1 && $argv[0] == __FILE__) {

//初始化pay的必要信息

$pay = new WechatPay(array(

WechatPay::APPID => 'wx99dabzpiuq83985b8',

WechatPay::APPSERCER => 'ac12e7e4abaer63hkoa0cc36a9663fa',

WechatPay::PARTNERKEY => 'bae4sfa3562rsfaq23s2045',

WechatPay::PARTNERID => '1268969802',

WechatPay::PAYSIGNKEY => '9Fqsxb3PK4IVOCEc4yCquy5zecS9LeeMjF2Nn4B4YKoOxPwaQdFwMezKT8oNlBYaWcuT',

WechatPay::SIGNTYPE => 'sha1',

));

//设置package 必要的参数 jsapi native都通用

$pay->setParams(WechatPay::BANK_TYPE, "WX");

$pay->setParams(WechatPay::BODY, "test");

$pay->setParams(WechatPay::PARTNER, $pay->partnerid);

$pay->setParams(WechatPay::OUT_TRADE_NO, commonUtil::createNoncestr());

$pay->setParams(WechatPay::TOTAL_FEE, "1");

$pay->setParams(WechatPay::FEE_TYPE, "1");

$pay->setParams(WechatPay::TIMESTAMP, time());

$pay->setParams(WechatPay::NOTIFY_URL, "http://www.demo.com/notify");

$pay->setParams(WechatPay::SPBILL_CREATE_IP, "127.0.0.1");

$pay->setParams(WechatPay::INPUT_CHARSET, "UTF-8");

//JSAPI的签名json

print_r($pay->createJsApiPackage());

//生成native XML

print_r($pay->createNativePackage());

//生成native URL

print_r($pay->createNativeUrl("9701"));

}

JS API生成的package签名包参数：

{

"appId":"wx9998ff5f4dede5b7",

"package":"bank_type=WX&body=test&fee_type=1&input_charset=UTF-8&notify_url=http%3A%2F%2Fwww.demo.com%2Fnotify&out_trade_no=Vf5qsSwtu0hc2loH&partner=wx9998ff5f4dede5b7&spbill_create_ip=127.0.0.1&timestamp=1409295711&total_fee=1&sign=FEE0167BD0D89A88BF6850590EA889B6",

"timeStamp":1409295711,

"nonceStr":"Vf5qsSwtu0hc2loH",

"paySign":"f816264c750923863c370a1739640244b0c2d39c",

"signType":"sha1"

}

Native 响应的XML格式：

1409296124

Native的URL链接：

weixin://wxpay/bizpayurl?appid=wx9998ff5f4dede5b7&noncestr=VY7cVA6mtVrc1BVq&productid=9701&sign=43508b65b50e1d7e1089be66d55a709469155d73&timestamp=1409296323

无论哪一种方式，我们都要通过setParams来设置必要初始化参数和商品价格和状态等！

WechatPay class:

class WechatPay {

const

BANK_TYPE = 'bank_type',

BODY = 'body',

PARTNER = 'partner',

OUT_TRADE_NO = 'out_trade_no',

TIMESTAMP = 'timestamp',

TOTAL_FEE = 'total_fee',

FEE_TYPE = 'fee_type',

NOTIFY_URL = 'notify_url',

SPBILL_CREATE_IP = 'spbill_create_ip',

INPUT_CHARSET = 'input_charset',

APPID = 'appid',

APPSERCER = 'appsercer',

PAYSIGNKEY = 'appkey',

PARTNERID = 'partnerid',

PARTNERKEY = 'partnerkey',

SIGNTYPE = 'signtype';

public

$params = array(), $partnerid = '';

static protected

$_instance;

protected

$_appid, $_appkey, $_signtype, $_partnerkey, $_appsercer;

static public function getInstance(array $options = array()) {

if (empty(self::$_instance)) {

self::$_instance = new self ($options);

}

return self::$_instance;

}

public function __construct(array $options = array()){

$this->_appid = $options[self::APPID];

$this->_signtype = $options[self::SIGNTYPE];

$this->_partnerkey = $options[self::PARTNERKEY];

$this->_appsercer = $options[self::APPSERCER];

$this->partnerid = $options[self::APPID];

}

public function setParams($param, $paramValue) {

$this->params[CommonUtil::trimString($param)] = CommonUtil::trimString($paramValue);

}

public function getParams($param) {

return $this->params[$param];

}

protected function createNoncestr( $length = 16 ) {

$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";

$str ="";

for ( $i = 0; $i < $length; $i++ ) {

$str.= substr($chars, mt_rand(0, strlen($chars)-1), 1);

}

return $str;

}

public function checkParams(){

//必要的9个参与签名的参数

if($this->params[self::BANK_TYPE] == null || $this->params[self::BODY] == null || $this->params[self::PARTNER] == null ||

$this->params[self::OUT_TRADE_NO] == null || $this->params[self::TOTAL_FEE] == null || $this->params[self::FEE_TYPE] == null ||

) {

return false;

}

return true;

}

* 生成package包

* @params 初始化类时用setParams方法定义必要的9个参数

* 排序后格式化url query形式再md5SignUtil类签名，再给合URL

protected function getPackageSign(){

try {

if (null == $this->_partnerkey || "" == $this->_partnerkey ) {

throw new Exception("密钥不能为空！" . "
");

}

$commonUtil = new CommonUtil();

ksort($this->params);

$unSignParaString = $commonUtil->formatUrlQuery($this->params, false);

$paraString = $commonUtil->formatUrlQuery($this->params, true);

$md5SignUtil = new MD5SignUtil();

return $paraString . "&sign=" . $md5SignUtil->sign($unSignParaString,commonUtil::trimString($this->_partnerkey));

} catch (Exception $e) {

echo ($e->getMessage());

}

* 生成签名方法

* @params appid appkey package timestamp noncestr 等参数而native事例代码中加上retcode reterrmsg两个参数

public function getPaySign($signObj){

foreach ($signObj as $k => $v){

$signParams[strtolower($k)] = $v;

}

try {

if ($this->_appkey == "") {

throw new Exception("APPKEY为空！" . "
");

}

$signParams["appkey"] = $this->_appkey;

ksort($signParams, SORT_STRING);

$commonUtil = new CommonUtil();

$signString = $commonUtil->formatPayUrlQuery($signParams, false);

return sha1($signString);

} catch (Exception $e) {

echo ($e->getMessage());

}

//JS API 签名其中nonceStr是作为订单号灌穿整个支付流程

public function createJsApiPackage(){

try {

if($this->checkParams() == false) {

");

}

$payObj["signType"] = $this->_signtype;

return json_encode($payObj);

} catch (Exception $e) {

die($e->getMessage());

}

* 构建发货状态数组主要三个参数openid transid orderid

public function createDeliverPost(Array $params) {

$deliver = array();

$deliver['appid'] = $this->_appid;

$deliver['deliver_status'] = 1;

$deliver['deliver_msg'] = 'OK';

$deliver['app_signature'] = $this->getPaySign($deliver);

$deliver['sign_method'] = 'sha1';

return $deliver;

}

* 生成扫描或者点击原生URL后，响应的XML格式

* @params $retcode $reterrmsg 定义该商品的状态

public function createNativePackage($retcode = 0, $reterrmsg = "ok") {

try {

if ($this->checkParams() == false && $retcode == 0) { //如果是正常的返回，检查财付通的参数

throw new Exception("生成package参数缺失！" . "
");

}

$commonUtil = new CommonUtil();

$xml = $commonUtil->arrayToXml($nativeObj);

* 生成原生URL 以订单号为参数这是灌穿整个支付流程

public function createNativeUrl($productid) {

* 取IP地址

public function getIp(){
