Question

我正在尝试在componentDidMount中获取数据，设置状态和更改路由，但无法完成（仅在单击屏幕后）。我想有些东西与fetch的异步性质有关但是如何修复？

componentDidMount(){

AsyncStorage.multiGet([USER_TOKEN, USER_REFRESH_TOKEN,USER_REMEMBERED]).then((data) => {
  const userRemembered = JSON.parse(data[2][1])
  const userAccessToken = data[0][1]
  const userRefreshToken = data[1][1]

  if (userRemembered) {
    fetch("SOME_URL", {
      method: "POST",
      headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        refreshToken: userRefreshToken
      })
    })
    .then(response => response.json())
    .then(responseData => {
      console.log(responseData); // only after clicking on the screen it is logged
      if (responseData.success) {
        AsyncStorage.multiSet([[USER_TOKEN,responseData.response.accessToken],[USER_REFRESH_TOKEN,responseData.response.refreshToken],[USER_REMEMBERED,JSON.stringify(true)]])
        this.setState({
          token:responseData.response.accessToken,
          refreshToken: responseData.response.refreshToken,
          isLoggedIn: true
        }) //only after clicking on the screen state is changed
        this.changeRoute(this.state) //only after clicking on the clicking on the screen route is changed
      }
      else {
        console.log("API is not responding");
      }
    })
    .catch((error) => {
      console.log(error)
    })
  }
  else{
    console.log('user has not checked Remember Me');
  }
})

}

我终于明白了。我打开了远程JS调试，这让事情搞得一团糟。我把它关掉了，一切正常。

在ComponentDidMount中获取数据不起作用
