无法在可观察到的Redux上解决POST调用

Question

[我正在开发一个本机应用程序，并使用Observable.fromPromise进行POST调用，我得到以下响应，但是我不确定如何捕获代码方面的响应，并且我也收到了一些警告] >

响应：

PromiseObservable {_isScalar: false, promise: Promise, scheduler: undefined}
promise: Promise
_40: 0
_55: Promise
_40: 0
_55: Promise

我正在使用mergeMap捕获响应，不确定在这种情况下为什么它不起作用

代码：

const testEpic: Epic<Action, ReduxState> = (
  action$: ActionsObservable<any>,
  store: MiddlewareAPI<any, ReduxState>,
) =>
  action$
    .ofType(TEST_GET)
    .mergeMap((action) => {
      return Observable.merge(
          .fetch('/testPath/pathData', payload) // return part which is working properly
          .mergeMap((response) => {
             // calls not coming here for POST, PUT, DELETE even though it is status 200
          })
      )
    }
    )
    .catch((error) => {

    })

Answer 1

尝试一下

fetch("/testPath/pathData", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

Answer 2

我已解决它，实际上是由于contentType不匹配而进入了'错误'
