       请求   
`async upload({ file }) {
  try {
    // 图片转换为2进制
    const p = new FormData()
    p.append('file', file)
    const res = await pdfAndImgSelf(p)
    this.$set(this.registerDirectorData[this.current], 'files', [{ name: file.name, value: res.data.data.url, imgurl: res.data.data.imgurl }])
  } catch (e) {
    this.$message.error('上传失败，请重新上传')
  }
},`

目前上传成功后还是走catch  并且页面没有上传的图片

走catch 肯定是 try 模块里有报错了，可以先打印下catch 的 err 信息看看 err信息 ，或者 try 里面debugger 调试看看哪一步报错了 没有失败原因很难定位问题
