Question

例如，我想做这样的事情：

{hostURL}/api/entities/14/15/16/17

反过来会带回对应ID的所有数据。这种方法行不通。我也试过了，但是也没用：

{hostURL}/api/entities?id=16&id=17

文档显示了如何使用一个ID（在HTTP请求处理下）使用它：https://github.com/angular/in-memory-web-api

有什么办法可以传递多个ID？

谢谢。

Answer 1

尝试将数组作为ID传递

let IDs = [16, 17];

{hostURL}/api/entities?ids={IDs}

也许这对您有用。

Answer 2

围绕它。我在angular-in-memory-web-api文档中找到了这个GitHub文件：https://github.com/angular/in-memory-web-api/blob/master/src/app/hero-in-mem-data-override.service.ts，并构建了以下解决方案：

import { getStatusText, STATUS } from 'angular-in-memory-web-api/http-status-codes';
import { InMemoryDbService, RequestInfo } from 'angular-in-memory-web-api';

  get(reqInfo: RequestInfo) {
    // Extract ids from URL
    const ids: Array<number> = reqInfo.req.urlWithParams.match(/[0-9]+/g).map(n => +(n));
    // If there's more than one ID in the URL then we call the appropriate function
    if (ids.length > 1) {
      return this.getRelationshipDetails(reqInfo, ids)
    }
  }

private getRelationshipDetails(reqInfo: RequestInfo, ids: Array<number>) {
  console.log('HTTP GET override')
  const entities = reqInfo.collection;
  return reqInfo.utils.createResponse$(() => {
    const data = entities.filter(entity => ids.indexOf(entity.id) !== -1)
    const dataEncapsulation = reqInfo.utils.getConfig().dataEncapsulation;
    const options: any = data ?
      {
        body: dataEncapsulation ? { data } : data,
        status: STATUS.OK
      } :
      {
        body: { error: `Entities with ids='${ids}' not found` },
        status: STATUS.NOT_FOUND
      };
    return this.finishOptions(options, reqInfo)
  });
}

private finishOptions(options: any, { headers, url }: RequestInfo) {
  options.statusText = getStatusText(options.status);
  options.headers = headers;
  options.url = url;
  return options;
}

是否可以将多个ID传递给angular-in-memory-web-api中的查询字符串？
