对于每个刚开始工作的新手来说，无论支付宝支付还是微信支付都是跑不掉的一个小门槛。
在加上本人比较技术比较渣（比较懒导致的），不太喜欢引用那么大的SDK，于是就简单集成了一下支付宝的支付。
但也只是只有支付而已哦，其他的一些功能还是自己用自己在集成吧，嘻嘻(#^.^#)还是懒。
废话不多说了，直接上代码：
/**
* 支付宝支付
*/
class Alipay
{
private $config =[
"app_id" => "************", //支付宝APPid
"rsaPrivateKey" => "************", //支付宝私钥
"rsaPublicKey" => "************", //支付宝公钥
"charset" => "utf-8",
"sign_type" => "RSA2",
"version" => "1.0",
];
private $submitUrl = "https://openapi.alipay.com/gateway.do" ;//提交地址
public $calltype = "app";//pc电脑端 app 手机和app端公用
public $submit_auto=true;
public function index($data)
{
$calltype=$this->calltype;
return $this->$calltype($data);
}
public function app($data)
{
$return_url=$data['return_url'];
$notify_url=$data['notify_url'];
$subject=$data['subject'];
$order_sn=$data['order_sn'];
$total=$data['total'];
$biz_content=[
'body'=>'',
'subject'=>$subject,
'out_trade_no'=>$order_sn,
'timeout_express'=>'30m',
'total_amount'=>$total,
'product_code'=>'QUICK_MSECURITY_PAY',
];

$signdata=$this->alisign($postdata);
$str=$this->keyandvalStr($signdata,1);
//返回链接不能带官方https链接
return $str;
}
public function pc($data)
{

$notify_url=$data['notify_url'];
$biz_content=[

$post=[

return $url;
}
public function alisign($data)
{
$rsaPrivateKey=$this->config['rsaPrivateKey'];
$buff = "";
ksort($data);
$buff=$this->keyandvalStr($data);
$str = chunk_split($rsaPrivateKey, 64, "\n");
$res = "-----BEGIN RSA PRIVATE KEY-----\n$str-----END RSA PRIVATE KEY-----\n";
$sign=$this->ras2Sign($buff,$res);
$data['sign']=$sign;
return $data;
}
function keyandvalStr($data,$flg=0)
{
$buff="";
foreach ($data as $k => $v) {
if($flg!=0 && $v != "" && !is_array($v))
{
$v=urlencode($v);
$buff .= $k . "=" . $v . "&";
}else{
if($k != "sign" && $v != "" && !is_array($v)){
$buff .= $k . "=" . $v . "&";
}
}
}
$buff = trim($buff, "&");
return $buff;
}
function ras2Sign($buff,$res)
{
$sign='';
openssl_sign($buff, $sign, $res, OPENSSL_ALGO_SHA256);
$sign = base64_encode($sign);
return $sign;
}
function formsubmithtml($action,$data)
{
$sHtml = "<form id='alipaysubmit' name='alipaysubmit' action='".$action."' method='POST'>";
foreach ($data as $key => $value) {
$val = str_replace("'","'",$value);
$sHtml.= "<input type='hidden' name='".$key."' value='".$val."'/>";
}
$sHtml = $sHtml."<input type='submit' class='paysubmit' value='ok' ></form>";
if($this->submit_auto==true)
{
$sHtml = $sHtml."<script>document.forms['alipaysubmit'].submit();</script>";
}
return $sHtml;
}
}
调用方法：
use pay\Alipay;
$callD=[
'return_url' => '支付完成跳转路径',
'notify_url' => '回调路径',
'total' => '支付总额',
'subject' => '支付说明',
'order_sn' => '生成订单号',
];
$url=$this->Alipay($callD);
public function Alipay($data,$flg=true)
{
$pay = new Alipay();
$pay->calltype='app';
$pay->submit_auto=$flg;
$pay=$pay->index($data);
return $pay;
}
以上即是本次分享的内容。
