php教程_ThinkPhp5.1制作微信支付以及支付后的几种状态说明

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
