Django服务端读取excel文件并且传输到接口

    path_name = "opboss_download_" + str(int(time.time())) + ".csv"
    print(path_name)

    write = Write_excel(path_name=path_name, sheet="opboss")

    data = ctx.get("data")
    for d in data:
        darr = []
        darr.append(d.get("asrtime"))
        darr.append(d.get("app_id"))
        darr.append(d.get("app_name"))
        darr.append(d.get("asrdevicetype"))
        darr.append(d.get("asrdevicetypename"))
        darr.append(d.get("asrdeviceid"))
        darr.append(d.get("asr"))
        darr.append(d.get("tts"))
        darr.append(d.get("nlp"))
        darr.append(d.get("intent"))
        write.add_content(darr)

    write.write_now()

    def file_iterator(file_name, chunk_size=512):
        with open(file_name, 'rb') as f:
            while True:
                c = f.read(chunk_size)
                if c:
                    yield c
                else:
                    break

    response = StreamingHttpResponse(file_iterator(path_name))
    response["Content-Type"] = "application/octet-stream"
    response["Content-Disposition"] = 'attachment;filename="{0}"'.format(path_name)

    return response

前端vue处的实现方法：

      <a href="javascript:;" class="btn"  @click="getDownloadDataOrNot">点击下载</a>

// 限制数据导出条数，超出一万条范围不让导出
    getDownloadDataOrNot(){
      if (this.total > 10000){
        alert("不好意思，你要导的数据超过1万条，请缩小导出范围，谢谢合作！")
      }else {
        this.getDownloadData(this.deviceid, this.page, this.size, this.startdate, this.enddate, this.app_id, this.intent, this.device_type_id);
      }
    },

大致是上面这样，如有错误，还请大虾们指教！
