vue中使用图片url直接下载图片
在这里插入图片描述

     // 下载图片
      downloadByBlob(url, name) {
        let image = new Image()
        image.setAttribute('crossOrigin', 'anonymous')
        image.src = url
        image.onload = () => {
          let canvas = document.createElement('canvas')
          canvas.width = image.width
          canvas.height = image.height
          let ctx = canvas.getContext('2d')
          ctx.drawImage(image, 0, 0, image.width, image.height)
          canvas.toBlob((blob) => {
            let url = URL.createObjectURL(blob)
            this.download(url, name)
            // 用完释放URL对象
            URL.revokeObjectURL(url)
          })
        }
      },

      download(href, name) {
        let eleLink = document.createElement('a')
        eleLink.download = name
        eleLink.href = href
        eleLink.click()
        eleLink.remove()
      },

直接调用即可
