我是新的反應原生和反應傳奇。我有api電話工作,並且據我所知,一切都按預期工作。但是,如何顯示我從服務器返回給用戶的錯誤。對不起,如果這是一個微不足道的問題。這裏是我到目前爲止的代碼反應本機REDX傳奇如何向用戶顯示錯誤
集裝箱/ GetUserInfo.js
moveToJoinScreen(){
this.props.getStudentAvator(vouchercode, DeviceInfo.getUniqueID(), 'iOS');
}
render() {
return (
<View style={styles.container}>
<TouchableHighlight onPress={() => this.moveToJoinScreen()} underlayColor='#ff000000'>
<Image style={styles.imagestyle} style={{height:60, width:150}} source={Images.joinNow} />
</TouchableHighlight>
<Text style={styles.welcome}>
{'\n'}
</Text>
<TouchableHighlight onPress={() => this.moveToRegisterScreen()} underlayColor='#ff000000'>
<Image style={styles.imagestyle} style={{height:80, width:150}} source={Images.registerMyId} />
</TouchableHighlight>
</View>
)
}
}
const mapDispatchToProps = dispatch => ({
getStudentAvator:(emailaddress, deviceid, platform) => dispatch(StudentActions.SetupVoucherRequest(vouchercode, deviceid, platform))
})
export default connect(null, mapDispatchToProps)(LaunchScreen)
這裏是saga.js
export function* SetupVoucherRequest(api, action) {
const { vouchercode, deviceid, platform } = action
if(vouchercode.length >11 || vouchercode.length < 10)
{
yield put(StudentCardActions.SetupVoucherFailuer())
return
}
// make the call to the api
const response = yield call(api.SetupVoucher, vouchercode, deviceid, platform)
if (response.ok) {
const firstUser = 'fahad'
const avatar = 'Avatar_Fahad'
// do data conversion here if needed
yield put(StudentCardActions.SetupVoucherSuccess(avatar))
} else {
yield put(StudentCardActions.SetupVoucherFailuer())
}
}
不知道我怎麼能傳遞錯誤回到容器頁面顯示錯誤。任何幫助將不勝感激。在此先感謝
訪問錯誤在你的UI有什麼地方可以閱讀如何設置maStateToProps。抱歉,仍然試圖學習所有這些東西。謝謝 – dogwasstar
