很多時候，在專案開發的時候需要用到微信支付介面調用，例如：商城製作、線上繳費、保險繳費等等，小編最近做了幾個水費收費系統、保函出具系統、線上報名系統，均用到了微信支付，以下把微信支付的製作以及支付後的幾種狀態說明列出，希望對大家有所幫助。
【掃碼支付】
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 $dataUri;
}【JSAPI介面支付】
public function jsApiPay($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 $jsApiParameters;
}【訂單查詢】
public function QueryOrder($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，官方解釋：附加數據，在查詢API和支付通知中原樣返回，可作為自訂參數使用，實際情況下只有支付完成狀態才會回傳該欄位。有時我們在開發時需要在查詢訂單時傳回一些特定的數值，例如：會員ID、支付訂單ID、申請ID、會員名稱等等，這時可以使用attach進行傳遞參數，但是attach是一個字串，有時常傳值的是數組，那麼只需要利json_encode轉換即可，例如：
$remarks = array(
'cid'=>1,
'member_id'=>2,
'apply_id'=>28,
);
$attach = json_encode($remarks);查詢訂單後，再用json_decode進行轉化，例如：
$arr = json_decode($result['attach'],true);
這裡得到的$arr是一個數組，直接按照數組的調用規則調用即可
當所查詢的訂單資訊不存在時，傳回如下：
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"

}當所查詢的訂單資訊支付失敗，傳回如下：
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"

["trade_state"] => string(6) "NOTPAY"
["trade_state_desc"] => string(15) "订单未支付"

["time_end"] => string(14) "20211111111938"
["total_fee"] => string(4) "2000"
["trade_state"] => string(7) "SUCCESS"
