Upload pictures/files via WeChat Mini Program

The official WeChat document provides methods for uploading files: 

wx.chooseMessageFile(Object object)

The basic library 2.5.0 starts to support, and the lower version needs to be compatible .

Select the file from the client session.

Mainly by changing the value of type to select the type that needs to be uploaded, it needs to be tested on a real machine 

The uploaded picture is as follows:

wx.chooseMessageFile({
  count: 10,
  type: 'image',
  success (res) {
    // tempFilePath可以作为img标签的src属性显示图片
    const tempFilePaths = res.tempFiles
  }
})
