1 微信支付
【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;}2 微信支付时attach参数的设置
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
3 微信支付的几种状态
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" ["return_code"] => string(7) "SUCCESS" ["return_msg"] => string(2) "OK" ["sign"] => string(64) "8779CA8C7F4931B4296C19FFFB176A3111F74B7244123A0C0EB7AD8DB2B1BDA49DA"}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" ["result_code"] => string(7) "SUCCESS" ["return_code"] => string(7) "SUCCESS" ["return_msg"] => string(2) "OK" ["sign"] => string(64) "7927EC724A7FDBFF034621B1EC492DB4D130AC13A43E4C66C7B6AD7889736CD5" ["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(22) { ["appid"] => string(18) "公众号APPId" ["attach"] => string(13) "你的传参值" ["bank_type"] => string(6) "OTHERS" ["cash_fee"] => string(1) "1" ["cash_fee_type"] => string(3) "CNY" ["device_info"] => string(1) "1" ["fee_type"] => string(3) "CNY" ["is_subscribe"] => string(1) "Y" ["mch_id"] => string(10) "商户ID" ["nonce_str"] => string(16) "Y8iYqXqHfs22hexX" ["openid"] => string(28) "支付者微信openid" ["out_trade_no"] => string(13) "1642682408295" ["result_code"] => string(7) "SUCCESS" ["return_code"] => string(7) "SUCCESS" ["return_msg"] => string(2) "OK" ["sign"] => string(64) "2F25084A568BBDA805DA8EE3FEB846448C9778DCBC2B745E8210D950E0742E38" ["time_end"] => string(14) "20220120204024" ["total_fee"] => string(1) "1" ["trade_state"] => string(7) "SUCCESS" ["trade_state_desc"] => string(12) "支付成功" ["trade_type"] => string(6) "NATIVE" ["transaction_id"] => string(28) "4200001358202201201811257221"}以上就是关于“怎么用ThinkPhp5.1脚本制作微信支付”这篇文章的内容，相信大家都有了一定的了解，希望小编分享的内容对大家有帮助，若想了解更多相关的知识内容，请关注编程网行业资讯频道。
