美国新冠肺炎疫情最新情况百度关键词优化软件如何

问题说明：

订单服务，查询预售但是出现Broken pipe；

测试版是正常的，正式版报错

解决方案

• 1、延长客户端超时时间

• // 查询预售单列表
  export function listPreOrder(query) {return request({url: '/order/presale/list',method: 'get',params: query,timeout: 10000 //添加请求响应时间未验证})
  }

  2、合理优化服务端接口代码，提升，降低响应时间和返回数据量
• 3、增加系统运行内存
• 测试版正常，说明代码没有问题，而且数据是4000条不多，查看服务器内存16G，已经使用13G，剩余是交换内存，所以导致执行失败
