我想从响应中删除 drugName 但它没有发生任何想法如何从传播运算符中删除属性？主文件

  const transformedResponse = transformResponse(response);
  const loggerResponse = {...transformedResponse};
  delete loggerResponse[drugName];
  console.log("LOGGER>>>>", loggerResponse);
  logger().info('Drug Price Response=', { ...loggerResponse, memberId: memberId, pharmacyId: pharmacyId });

\ 数据

LOGGER>>>> {
    '0': {
        isBrand: false,
        drugName: 'test drug',
        drugStrength: '5 mg 1 5 mg',
        drugForm: 'Tablet',
    }
}

变换响应

[{
    drugName: 'HYDROCODONE-HOMATROPINE MBR',
    drugStrength: '5MG-1.5MG',
    drugForm: 'TABLET',
    brand: false
}]

我有来自后端的数据流,我看到它在控制台中打印现在我正在尝试将事件推送到dataSource其抛出错误dataSource未定义.有人可以帮助如何动态添加数据到物化表？

import {
    StreamService
} from '../stream.service';
import {
    MatTableDataSource
} from '@angular/material';
import * as io from 'socket.io-client';

@Component({
    selector: 'app-stream',
    templateUrl: './stream.component.html',
    styleUrls: ['./stream.component.css']
})
export class StreamComponent implements OnInit {
    displayedColumns = ['ticketNum', "assetID", "severity", "riskIndex", "riskValue", "ticketOpened", "lastModifiedDate", "eventType"];
    dataSource: MatTableDataSource < Element[] > ;
    socket = io();

    constructor(private streamService: StreamService) {};

    ngOnInit() {
        this.streamService.getAllStream().subscribe(stream => {

我想删除Bootstrap网格中多列之间的空格.

我们如何覆盖Bootstrap的CSS以实现此任务或使用纯CSS的任何其他更好的解决方案？

main.html中

<div class="row">
  <div class="col-md-2">
    // stuff here for this column
  </div>
  <div class="col-md-10">
    // stuff here for columns
  </div>
</div>

我有socket.io工作,app.js但当我试图从其他模块调用它不创造io.connection不确定？

app.js

var app = express();
var server = require('http').createServer(app);
var io = require('socket.io')(server);
var ditconsumer = require('./app/consumers/ditconsumer');
ditconsumer.start(io);
server.listen(3000, function () {
    console.log('Example app listening on port 3000!');
});

consumer.js

module.exports = {
    start: function (io) {
        consumer.on('message', function (message) {
            logger.log('info', message.value);
            io.on('connection', function (socket) {
                socket.on('message', function(message) {
                    socket.emit('ditConsumer',message.value);
                    console.log('from console',message.value);
                });
            });
        });
}
}

我在尝试解决的代码中有错误。我认为它需要一个return语句，但我已经在forEach循环之外，但它仍然抛出错误：

not all the code path return the value

如何修复下面的代码？

main.ts：

private ValidateRequestArgs(str) {
  let ret: boolean = true;
  // here on val its throwing tslint error not all code paths return value 
  str.split(',').forEach((val) => {
    if (!ret) {
      return false;
    }
    if (List.indexOf(val) > -1) {
      ret = true;
    } else {
      ret = false;
    }
  });
  return ret;
}

我想在将数据记录到文件之前创建并保存文件.以下方法是创建数据并将其保存到文件,并且只有Chrome浏览器支持.如何创建和保存空白文件,然后将数据记录到其中并支持IE和Chrome？

    a.download = name;
}
$scope.recordLogs = function(){
    download('file text', 'myfilename.txt', 'text/plain')
}

我已经socket.emit从客户端调用服务器作为响应我希望有文件名到客户端没有发生以下代码不确定什么是错误的任何想法,我没有看到任何错误.如何获得服务器使用的响应socket.emit？
