【扫码支付】
public function wxPayImg($body,$out_trade_no,$fee,$product_id,$logo,$path,$attach,$pro_id){
require_once Env::get('app_path')."api/wxpay/lib/WxPay.Api.php";
//实例化配置信息
$config = new WxPayConfig();
$input = new \WxPayUnifiedOrder();
//设置商品描述
$input->SetBody($body);
//设置订单号
$input->SetOut_trade_no($out_trade_no);
//设置商品金额(单位:分)
$input->SetTotal_fee($fee);
//设置异步通知地址
$notify = $config->GetNotifyUrl();
$input->SetNotify_url($notify);
//设置交易类型
$input->SetTrade_Type('NATIVE');
//设置商品ID
$input->SetProduct_id($product_id);
$input->SetDevice_info($pro_id);
$input->SetAttach($attach);
//调用统一下单API
$result = \WxPayApi::unifiedOrder($config,$input);
//dump($result);
$qr_url = $result['code_url'];
$img = $this->createCode($qr_url,$logo,$path);
//生成数组
$array = array('img'=>$img,'out_trade_no'=>$out_trade_no);
return $array;
}
//生成二维码
public function createCode($code_url,$logo,$path){
//创建基本的QR码
$qrCode = new QrCode($code_url);
$qrCode->setSize(300);
//设置高级选项
$qrCode->setWriterByName('png');
$qrCode->setEncoding('UTF-8');
$qrCode->setErrorCorrectionLevel(ErrorCorrectionLevel::HIGH());
$qrCode->setForegroundColor(['r' => 0, 'g' => 0, 'b' => 0, 'a' => 0]);
$qrCode->setBackgroundColor(['r' => 255, 'g' => 255, 'b' => 255, 'a' => 0]);
//$qrCode->setLabel('', 16, App::getAppPath().'/../public/static/user/font/msyhl.ttc', LabelAlignment::CENTER());
$qrCode->setLogoPath($logo);
$qrCode->setLogoWidth(50);
$qrCode->setValidateResult(false);
//边距设置
$qrCode->setMargin(10);
//直接输出二维码
header('Content-Type: '.$qrCode->getContentType());
//echo $qrCode->writeString();
//将二维码保存到指定目录
$qrCode->writeFile($path);
//生成数据URI以内联图像数据(即在<img>标记内)
$dataUri = $qrCode->writeDataUri();
return $dataUri;
}
【JSAPI接口支付】
public function jsApiPay($openId,$Body,$out_trade_no,$fee,$product_id,$attach){
require_once Env::get('app_path')."api/wxpay/lib/WxPay.Api.php";
$tools = new JsApiPay();
$input = new \WxPayUnifiedOrder();
//设置商品描述
$input->SetBody($Body);
//设置订单号
$input->SetOut_trade_no($out_trade_no);
//设置商品金额(单位:分)
$input->SetTotal_fee($fee);
//设置异步通知地址
$config = new WxPayConfig();
$notify = $config->GetNotifyUrl();
$input->SetNotify_url($notify);
//设置交易类型
$input->SetTrade_Type('JSAPI');
//设置商品ID
$input->SetProduct_id($product_id);
//用户openID
$input->SetOpenid($openId);
$input->SetAttach($attach);
//调用统一下单API
$result = \WxPayApi::unifiedOrder($config,$input);
$jsApiParameters = $tools->GetJsApiParameters($result);
return $jsApiParameters;
}
【订单查询】
public function QueryOrder($number,$transaction_id=NULL){
require_once App::getAppPath().'api/wxpay/lib/WxPay.Api.php';
require_once App::getAppPath().'api/wxpay/lib/WxPay.Notify.php';
$input = new \WxPayOrderQuery();
$input->SetOut_trade_no($number);
$input->SetTransaction_id($transaction_id);
$config = new WxPayConfig();
$result = \WxPayApi::orderQuery($config, $input);
if($result['result_code']=='SUCCESS'){
if($result['trade_state']=='SUCCESS'){
$arr = json_decode($result['attach'],true);
$pay_time = $this->getPayTime($result['time_end']);
return ['code'=>100,'result_code'=>$result['result_code'],'attach'=>$arr,'pay_time'=>$pay_time,'result'=>$result,'msg'=>"支付成功"];
}else{
return ['code'=>101,'result_code'=>$result['result_code'],'err_code'=>$result['err_code'],'result'=>$result,'msg'=>"订单未支付"];
}
}else{
return ['code'=>103,'result_code'=>$result['result_code'],'result'=>$result,'msg'=>"订单不存在"];
}
//dump($result);
//return $result;
}
attach,官方解释:附加数据,在查询API和支付通知中原样返回,可作为自定义参数使用,实际情况下只有支付完成状态才会返回该字段。有时我们在开发时需要在查询订单时返回一些特定的数值,比如:会员ID、支付订单ID、申请ID、会员名称等等,这时可以使用attach进行传递参数,但是attach是一个字符串,有时往往传值的是数组,那么只需要利json_encode进行转化即可,例如:
$remarks = array(
'cid'=>1,
'member_id'=>2,
'apply_id'=>28,
);
$attach = json_encode($remarks);
查询订单后,再用json_decode进行转化,例如:
$arr = json_decode($result['attach'],true);
这里得到的$arr是一个数组,直接按照数组的调用规则调用即可
当所查询的订单信息不存在时,返回如下:
array(9) {
["appid"] => string(18) "公众号APPId"
["err_code"] => string(13) "ORDERNOTEXIST"
["err_code_des"] => string(15) "订单不存在"
["mch_id"] => string(10) "商户ID"
["nonce_str"] => string(16) "H0K6KPemexExM5DV"
["result_code"] => string(4) "FAIL"

}
当所查询的订单信息支付失败,返回如下:
array(11) {
["appid"] => string(18) "公众号APPId"
["attach"] => string(13) "你的传参值"
["mch_id"] => string(10) "商户ID"
["nonce_str"] => string(16) "BR3zfazCdI3vZj5e"
["out_trade_no"] => string(13) "1636555204840"

["trade_state"] => string(6) "NOTPAY"
["trade_state_desc"] => string(15) "订单未支付"
}
当所查询订单信息存在时返回如下:
array(21) {

["cash_fee"] => string(4) "2000"
