vue文件上传

前端部分

    <input
      id="upload"
      style="display:none"
      type="file"
      @change="getFile($event)"
    />

    getFile (event) {
      let self = this
      console.log(event.target.files)
      if (event.target.files[0].name.indexOf(this.upFileType) > -1) {
        let file = event.target.files[0]
        let formData = new FormData()
        formData.append('project', this.upProject)
        formData.append('moduleId', this.upModuleId)
        formData.append('module', this.upModule)
        formData.append('fileInfo', file)
        formData.append('initFileType', this.upFileType)
        commData
          .uploadCon(formData)
          .then(data => {
            console.log(data)
            if (data.success) {
              // 这边需要清空，不然重复文件不会继续上传
              event.srcElement.value = ''
              self.$message({
                type: 'success',
                message: data.msg
              })
              if (this.upProject === 'init') {
                self.getInitProData(1, this.initProPageInfo.pageSize)
              } else {
                self.getOtherProData(1, this.otherProPageInfo.pageSize)
              }
            } else {
              self.$message({
                type: 'error',
                message: data.msg
              })
            }
          })
          .catch(e => {
            self.$message.error('服务端出错')
            console.error(e)
          })
      } else {
        this.$message({
          type: 'warning',
          message: '上传文件和所选格式不一致!'
        })
      }
    }

请求头部

const remoteStartByFile = postparam => {
  return new Promise((resolve, reject) => {
    axios
      .post('/comm/uploadCon', postparam, {
        headers: { 'Content-Type': 'multipart/form-data' }
      })
      .then(response => {
        resolve(response)
      })
      .catch(e => {
        reject(e)
      })
  })
}

后台部分
