无法解析 POST 对 redux observable 的调用

Question

我正在开发一个 React 本机应用程序，并正在使用 Observable.fromPromise 进行 POST 调用，我收到以下响应，但我不确定如何捕获响应代码，我也收到了一些警告

回复：

PromiseObservable {_isScalar: false, promise: Promise, scheduler: undefined}
promise: Promise
_40: 0
_55: Promise
_40: 0
_55: Promise
_40: 0
_51: 3
_55: Response
bodyUsed: true
headers: Headers {map: {…}}
ok: true
status: 200
statusText: undefined
type: "default"
url: "http://localhost:9999/testPath/pathData"
_bodyBlob: Blob {_data: {…}}
_bodyInit: Blob {_data: {…}}
__proto__: Object
_65: 2
_72: null
__proto__: Object
_65: 3
_72: null
__proto__: Object
_65: 3
_72: null
__proto__: Object
scheduler: undefined
_isScalar: false
__proto__: Observable

警告：

我正在使用 mergeMap 来捕获响应，不确定为什么在这种情况下它不起作用

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

试试这个

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

Answer 2

我已经解决了，实际上它进入了内部 'error' 因为 contentType
