Small micro-channel program more and more fire, because micro-channel has become essential to everyone we chat every day, no matter from children and to the elderly, almost always play to the letter, and app memory for feeling too much, most people are not willing to download, so small micro letter that came with the program to become the people's favorite, so small program to download video files and pictures how it, a small ape lap belt you look.

Download (encounter pits)

1. To distinguish what content is downloaded

0.1 Pictures Download wx.saveImageToPhotosAlbum (Objectobject)

0.2 video download wx.saveVideoToPhotosAlbum (Objectobject)

It is more than two categories

2. Routing Problem

Picture file path, file path can be temporary or permanent file path, the path does not support network picture

It does not support the need to deal with how to use

DownloadTaskwx.downloadFile(Objectobject)

Download the file to a local resource. The client initiates a HTTPSGET direct request, returns the file path of the local temporary

That becomes a path through the network Download the local temporary path

3. My code (picture download stories, need to use video wx.saveVideoToPhotosAlbum)

var url = '网络图片'
wx.downloadFile({
  url: url, //下载资源的地址网络
  success: function (res) {
  //console.log(res)
  // 只要服务器有响应数据，就会把响应内容写入文件并进入 success 回调，业务需要自行判断是否下载到了想要的内容
  if (res.statusCode === 200) {
    wx.playVoice({
    filePath: res.tempFilePath
    })
  }
  // 保存图片到本地
  wx.saveImageToPhotosAlbum({
    filePath: res.tempFilePath,
    success:
    function (data) {
      //console.log(data);
      wx.showModal({
      title: '下载成功',
      content: '图片以保存至您的手机',
      })
    },
  })
  }
})
