向微信登录请求，拿到code，再将code提交换取openId
wx.login({
success: function(res) {
if (res.code) {
//发起网络请求
wx.request({
url: 'https://api.weixin.qq.com/sns/jscode2session?appid=wx9114b997bd86f***&secret=d27551c7803cf16015e536b192******&js_code='+res.code+'&grant_type=authorization_code',
data: {
code: res.code
},
success: function (response) {
console.log(response);
}
})
} else {
console.log('获取用户登录态失败！' + res.errMsg)
}
}
});
从控制台看到已经成功拿到openid，剩下的事情就是将它传到服务端就好了，服务端那边$this->input->post('openId')等着收呢。
5. 小程序端向https://lendoo.leanapp.cn/index.php/WXPay发起请求，作统一下单
//统一下单接口对接
wx.request({
url: 'https://lendoo.leanapp.cn/index.php/WXPay',
data: {
openId: openId
},
success: function (response) {
console.log(response);
},
header: {
'content-type': 'application/x-www-form-urlencoded'
},
});
得到如下结果
{
"appid": "wx9114b997bd86f8ed",
"mch_id": "1414142302",
"nonce_str": "eEICgYFuGqxFRK6f",
"prepay_id": "wx201701022235141fc713b8f80137935406",
"result_code": "SUCCESS",
"return_code": "SUCCESS",
"return_msg": "OK",
"sign": "63E60C8CD90394FB50E612D085F5362C",
"trade_type": "JSAPI"
}
前提是https://lendoo.leanapp.cn已经在白名单。
6. 小程序端调起支付API
// 发起支付
var appId = response.data.appid;
var timeStamp = (Date.parse(new Date()) / 1000).toString();
var pkg = 'prepay_id=' + response.data.prepay_id;
var nonceStr = response.data.nonce_str;
var paySign = md5.hex_md5('appId='+appId+'&nonceStr='+nonceStr+'&package='+pkg+'&signType=MD5&timeStamp='+timeStamp+"&key=d27551c7803cf16***e536b192d5d03b").toUpperCase();
console.log(paySign);
console.log(appId);
wx.requestPayment({
'timeStamp': timeStamp,
'nonceStr': nonceStr,
'package': pkg,
'signType': 'MD5',
'paySign': paySign,
'success':function(res){
console.log('success');
console.log(res);
}
});
