#The operating environment of this tutorial: windows7 system, React17 version, thinkpad t480 computer.

React mock data method:

The following code calls thegetList()method when the input gains focus.

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

The getList() method obtains data through Ajax. At this time, the backend has not been written yet, so I mock the data myself.

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')With this code, the computer will first go to the src directory to look for /api/headerList.json. If it is not found, it will go to public Find it in the directory. At this time, we create the /api/headerList.json file in the public directory. The file is as follows:

{ "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"] }

The data returned at this time is the above data, throughconsole.log(res.data )Print the data as shown below:

In this way, the mock data will be successful.
