调用服务端接口生成小程序二维码

image

坑1

scene的参数值必须有，没有就报格式不符合要求

express收到二进制后直接返回image给前端

request({
            url: path,
            method: "POST",
            encoding: null,
            body: JSON.stringify(req.body)  
        }, function(error, response, body) {
            // 这里收到的是二进制buffer，需要把二进制转为图片返回给前端
            res.set({
                'Content-Type': 'image/png',
            })
            res.send(body)
});

加载自定义字体

const util = require('utils/util.js');

App({

  onLaunch: function () {
    //加载思源黑体
    util.getFontFamily();
  },
})

//这个方法建议放到公共文件中，例如我这里是utils.js
function getFontFamily() {
  wx.loadFontFace({
    family: 'webfont',
    source: 'url("//d.sicq.org/assets/src/SourceHanSansCN-Normal.ttf")',//这个文件放到您的服务器根目录下
    success: function (res) {
      console.log(res.status) // loaded 
    },
    fail: function (res) {
      console.log(res.status) // error 
    },
    complete: function (res) {
      console.log(res.status);
    }
  });

坑1: session_key必须有效

使用云开发直接获取加密数据

由于该错误一直无法解决，更改为使用云开发方案替代
