Vue2下载xlsx文件无法打开问题

Vue2下载xlsx文件无法打开问题

问题原因：项目中使用了Mock与file.download产生冲突
解决方法：在mock.js中添加如下代码

Mock.XHR.prototype.send = (() => {
  const _send = Mock.XHR.prototype.send
  return function () {
    if (!this.match) {
      this.custom.xhr.responseType = this.responseType || ''
      this.custom.xhr.timeout = this.timeout || 0
      this.custom.xhr.withCredentials = this.withCredentials || false
      this.custom.xhr.onabort = this.onabort || null
      this.custom.xhr.onerror = this.onerror || null
      this.custom.xhr.onload = this.onload || null
      this.custom.xhr.onloadend = this.onloadend || null
      this.custom.xhr.onloadstart = this.onloadstart || null
      this.custom.xhr.onprogress = this.onprogress || null
      this.custom.xhr.onreadystatechange = this.onreadystatechange || null
      this.custom.xhr.ontimeout = this.ontimeout || null
    }
    return _send.apply(this, arguments)
  }
})()

重启项目即可打开文件成功。
