记录下开发微信小程序时,遇到的一些坑:
1. 微信小程序真机调试的时候,报错request:fail url not in domain list

2. 图片缩放通过画布实现,要采用回调函数。
const ctxx = wx.createCanvasContext('attendCanvasId'); ctxx.drawImage(tempImagePath, 0, 0, windowWidth, windowHeight * 0.5); ctxx.draw(false, wx.canvasToTempFilePath({ canvasId: 'attendCanvasId', success: function (res) { tempImagePath = res.tempFilePath; console.log(tempImagePath); wx.hideToast() }, fail: function (res) { console.log(res); } }));
