POST不使用React组件

Question

我正在关注教程：http://sahatyalkabov.com/create-a-character-voting-app-using-react-nodejs-mongodb-and-socketio/

我遇到POST问题。当我使用Chrome的Postman时，我可以成功更新api。但是当我尝试通过反应组件时，我无法这样做。

这让我相信AddCharacter.js存在问题，但我无法弄清楚原因。在提交时，调用handleSubmit函数，然后调用AddCharacterActions函数，然后最终调用addCharacter（在AddCharacterActions.js中），这是一个AJAX POST。那么它如何与server.js（/ api / characters）中的内容联系起来呢？

server.js

...

app.post('/api/characters', function(req, res, next) {

  var gender = req.body.gender;
  var name = req.body.name;

  var character = new Character({

    name: name,
    gender: gender
  });

  character.save(function(err) {
    if (err) return next(err);
    res.send({ message: name + ' has been added successfully!' });
  });

});

AddCharacterActions.js

import alt from '../alt';

class AddCharacterActions {
  constructor() {
    this.generateActions(
      'addCharacterSuccess',
      'addCharacterFail',
      'updateName',
      'updateGender',
      'invalidName',
      'invalidGender'
    );
  }

  addCharacter(name, gender) {
    $.ajax({
      type: 'POST',
      url: '/api/characters',
      data: { name: name, gender: gender }
    })
      .done((data) => {
        this.actions.addCharacterSuccess(data.message);
      })
      .fail((jqXhr) => {
        this.actions.addCharacterFail(jqXhr.responseJSON.message);
      });
  }
}

export default alt.createActions(AddCharacterActions);
