方法用Express、Axios和React删除不起作用

Question

我用axios.js和react编写的代码：

remove = (name, id) => {
  axios.delete('http://127.0.0.1:9000/people/' + id).
  then((response => id.splice(name, 1)))
}

我的express.js:

js lang-js prettyprint-override">app.delete('/people', function (req, res) {
  res.send('DELETE request to homepage');
});

和错误：

未捕获（promise中）错误：在xmlHttpRequest.HandleError(xhr.js:87)的createError（createError.js:16)处出现网络错误

谁来帮帮我？

您似乎试图将ID作为请求参数发送给您的后盾。

你必须

更改axios.delete('http://127.0.0.1:9000/people/'+id).

app.delete('/people', function (req, res) {

 app.delete('/people/id', function (req, res) {

app.use(function (req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
