移动端h5图片压缩上传

移动端H5图片压缩上传

大体的思路是,部分API的兼容性请参照caniuse

  1. 利用FileReader,读取blob对象,或者是file对象,将图片转化为data uri的形式。
  2. 使用canvas,在页面上新建一个画布,利用canvas提供的API,将图片画入这个画布当中。
  3. 利用canvas.toDataURL(),进行图片的压缩,得到图片的data uri的值
  4. 上传文件。

步骤1当中,在进行图片压缩前,还是对图片大小做了判断的,如果图片大小大于200KB时,是直接进行图片上传,不进行图片的压缩,如果图片的大小是大于200KB,则是先进行图片的压缩再上传:
