'Argument expression expected' 在 ajax 调用 rxjs 时出错

Question

我在使用 api 调用后收到此错误。我正在尝试从 myjson api 获取数据。我是在对当前的实现做错什么，还是有更好的方法来调用相同的 api.

import { createAction, handleActions } from 'redux-actions'
import { PLUGIN_NAME, STORE_MOUNT_POINT } from '../constants'
import { Epic,ofType } from 'redux-observable'
import { Store } from '../Store'
import { defer, of } from 'rxjs'
import { mergeMap } from 'rxjs/operators'
import { ajax } from '../util'

const fetchReportTemplate$: Epic<Store.IFSA> = (action$, state$) =>
  action$.ofType(startFetchReportsTemplate.toString(),
      return  ajax(
          {
            url: 'https://api.myjson.com/bins/15dcd9',
            body: ''
          }
        )
      ).map(({ response: { data } }) => {
        return of(clearAllHttpErrors(), receiveReportsTemplateRows(data))
        })

是的，这是您代码中的语法错误。

action$.ofType(startFetchReportsTemplate.toString(),
      // here, floating return without function
      return  ajax(
