2.生成带参数小程序二维码：

var parameters = {

scene: "pageurl=qrcode&userid=" +that.data.userInfo.AutoId,

page: "pages/index/index",

width: 430

}

wx.request({

url: getApp().globalData.api + '/api/WeChat/GetQrCodeImage',

data: JSON.stringify(parameters),

method: 'PUT',

responseType: 'arraybuffer',

success: function(res) {

console.log(res);

let data = wx.arrayBufferToBase64(res.data);

that.setData({

qrcodeUrl: 'data:image/jpeg;base64,' + data

})

}

})

}

});

3.获取二维码代码

var scene =    decodeURIComponent   (options.scene);

console.log("The from qrcode and share info is " + scene);

//var scene = "pageurl=qrcode&userid=4"

var url = scene.split("&")[0].split("=")[1]

var id = scene.split('&')[1].split("=")[1];

if (url == "qrcode") {

that.setData({

pageUrl: "store",

isLoad: true,

userId: id

});

}
