我有用户登录名,并且我有2个错误处理程序

>电子邮件和密码为空
>电子邮件和密码与数据库不匹配

通过邮递员我发送

>空的用户名和密码结果是

{
    "errors": {
        "email": "please enter valid emails",
        "password": "please enter password"
    }
}

>电子邮件和密码错误,结果是

{
    "general": "email or password not match"
}

我注意到第一个错误有对象错误,第二个没有

我的反应js代码是

// i remove css and imports 

class login extends Component {
    constructor() {
        super();
        this.state = {
            email: '',
            password: '',
            loading: false,
            errors: {}

        }
    }
    handleChnage = (event) => {
        this.setState({
            [event.target.name]: event.target.value
        })
    }
    handleSubmit = (event) => {
        // console.log('hi');
        event.preventDefault();
        this.setState({
            loading: true
        });
        const userData = {
            email: this.state.email,
            password: this.state.password
        }
        axios.post('/login', userData)
            .then((res) => {
                //console.log(res.data)
                this.setState({
                    loading: false
                });
                this.props.history.push('/');
            })
            .catch((err) => {
                console.log(err.response.data)
               // let errors  ={email:'',password:''}
                this.setState({
                    //errors11: err.response.data.errors,
                    errors : err.response.data.errors,
                    // error2:err.response.data,
                    loading: false
                })
            })
    }
    render() {
        const { classes } = this.props;
        const { errors, loading,} = this.state;
        return (
            <Grid container className={classes.form}>
                <Grid item sm />
                <Grid item sm >
                    <img src={AppIcon} alt="app cion" className={classes.image} />
                    <Typography variant="h2" className={classes.pagetitle}>Login</Typography>
                    <form noValidate onSubmit={this.handleSubmit}>
                        <TextField id="email" name="email" type="email" label="Email" className={classes.textfeild}
                            helperText={errors.email} error={errors.email ? true : false} value={this.state.email} onChange={this.handleChnage} fullWidth />
                        <TextField id="password" name="password" type="password" label="Password" className={classes.textfeild}
                            helperText={errors.password} error={errors.password ? true : false} value={this.state.password} onChange={this.handleChnage} fullWidth />
                        {errors.general &&(
                            <Typography variant="body2" className={classes.customerror}>
                                {errors.general}
                            </Typography>
                        )}
                        <Button type="submit" variant="contained" color="primary" className={classes.button}>Login </Button>
                    </form>
                </Grid>
                <Grid item sm />
            </Grid>
        )
    }
}

login.propTypes = {
    classes: PropTypes.object.isRequired
}

export default withStyles(styles)(login);

如果我发送电子邮件和密码错误,我的问题是在此代码中

93 | helperText = {errors.email} error = {errors.email吗？ true：false} value = {this.state.email} onChange = {this.handleChnage} fullWidth

这行我有错误,这是我的控制台日志

general: "email or password not match"

我该如何处理此类错误？

解决方法:

查看您的请求处理代码和响应,我可以看到错误响应在处理错误方面是不一致的.我认为您应该考虑将响应固定为一致的.我会尝试在提交的错误处理中替换行

errors : err.response.data.errors,

会为一般错误创造结构的东西：f.e.

errors : {...err.response.data.errors, general: err.response.data.general}
