react怎么mock数据-木庄网络博客

react mock数据的方法：首先在public目录下建立【/api/headerList.json】文件；然后加入相关代码【axios.get('/api/headerList.json')】。

本教程操作环境：windows7系统、React17版、thinkpad t480电脑。

react mock数据的方法：

如下代码，在input获得焦点时调用getList()方法。

const mapDispathToProps = (dispatch) => {
    return {
        handleInputFocus() {
            dispatch(actionCreators.getList())
        }
    }
}

getList()方法是通过Ajax获取数据，此时后端并没有写好，所以自己mock一个数据。

export const getList = () => {
    return (dispatch) => {
        axios.get('/api/headerList.json').then((res) => {
            const data = res.data;
            console.log(data)
        }).catch(() => {
            console.log('error')
        })
    }
}

axios.get('/api/headerList.json')这句代码，计算机会首先去src目录下寻找/api/headerList.json，没有找到然后去public目录下找，此时我们在public目录下建立/api/headerList.json文件，文件如下：

{
    "success":true,
    "data":["微信","支付宝","蚂蚁金服","被骗","借呗","诈骗","盗窃","pandas","TensorFlow","PyTorch","Caffe","scikit-learn","Python","Keras","pyecharts","ggplot","Matplotlib","Gensim","Bokeh","Theano","Scrapy","SciPy","Plotly","NumPy","XGBoost","是","他","有","光大永明","我","要","人","Android","女","大","不","着","男","它","二","于","中","java","把","上","这","下","的","了","来"]
}
