- 点击上传图片,拍照上传,确认图片后,加载中然后就没有了,没有上传图片
- 应该是打印出返回的data
-
"pages/upPoto/main"
- 提供一个最简复现 Demo
data () {
return {
imgMaxWidth: 1500,
imgMaxHeight: 1500}
},
methods: {

var taskid = Number(id)
var that = this
var FSM = wx.getFileSystemManager()
wx.chooseImage({
count: 1, // 默认9
sizeType: ['compressed'], // 指定只能为压缩图,首先进行一次默认压缩
sourceType: ['camera'], // 可以指定来源是相册还是相机,默认二者都有
success: function (photo) {
wx.getImageInfo({

success: function (res) {
var imgHeight = 0
var imgWidth = 0
var containerRatio = that.imgMaxWidth / that.imgMaxHeight
var imgRatio = res.width / res.height

var ctx = wx.createCanvasContext('canvas')
ctx.drawImage(res.path, 0, 0, that.cWidth, that.cHeight)
ctx.draw(false, setTimeout(function () {

fail: function (res) {
console.log(res.errMsg)

}
}
我也遇到这个问题,有没有结果喃
请问解决了吗,我这边也碰到这个问题,好几个用户反馈,选了图片,显示压缩中,请稍后,然后就没有然后了,其中一个手机型号是华为P9
H5还是小程序?报错信息是什么?
真机测试看看报没报错
请大神们帮我看看,这个为什么iphone没有执行成功,可以拍照,确定照片,但是显示加载中,然后就什么都没有了
