小程序端页面初始化内容如下：javascriptPage({ data: { userN: '' }, payInput: function(e) { console.log(e); this.setData({ userN: e.detail.value }); }, loginBtnClick: function() { getApp().onLaunch(function(openid) { // ... }); }});

小程序端

// pages/pay/pay.js Page({ /** * 页面的初始数据 */ data: { }, payInput: function (e) { console.log(e) this.setData({ userN: e.detail.value }) }, loginBtnClick: function () { getApp().onLaunch(function (openid) { var openid = JSON.stringify(openid.data) wx.setStorageSync("openid",openid) }) var openid = wx.getStorageSync('openid') if (this.data.userN.length <= 0 ) { this.setData({ infoMess: '温馨提示：请输入正确的金额！', }) } else { wx.request({ url: 'gong.90plus.cn/app/Pay/payfee', //你服务器code.php文件地址，默认GET。小程序只支持api.mch.weixin.qq.com/pay/unifiedorder'; $parameters = array( 'appid' => $appid, //小程序ID 'mch_id' => $mch_id, //商户号 'nonce_str' => $this->createNoncestr(), //随机字符串 // 'body' => 'test', //商品描述 'body' => $body, // 'out_trade_no' => '2015450806125348', //商户订单号 'out_trade_no'=> $out_trade_no, // 'total_fee' => floatval(0.01 * 100), //总金额 单位 分 'total_fee' => $total_fee, // 'spbill_create_ip' => $_SERVER['REMOTE_ADDR'], //终端IP 'spbill_create_ip' => '116.62.121.247', //终端IP 'notify_url' => 'www.weixin.qq.com/wxpay/pay.php', //通知地址 确保外网能正常访问 'openid' =>$openid, //用户id 'trade_type' => 'JSAPI'//交易类型 ); //统一下单签名 $parameters['sign'] = $this->getSign($parameters); $xmlData = $this->arrayToXml($parameters); $return = $this->xmlToArray($this->postXmlCurl($xmlData, $url, 60)); return $return; } private function xmlToArray($xml) { //禁止引用外部xml实体 libxml_disable_entity_loader(true); $xmlstring = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA); $val = json_decode(json_encode($xmlstring), true); return $val; } //数组转换成xml private function arrayToXml($arr) { $xml = " "; foreach ($arr as $key => $val) { if (is_array($val)) { $xml .= "<" . $key .
