Node.js 快速路线的Redux操作需求主体未定义

我一直在努力使用这个功能，它应该将redux表单值发送到我的express服务器，并等待mongoose模型

到达快速路由后的请求正文不包含我在redux操作中发送的表单值。表单值在客户端（在submitInvestment操作中）正确记录。但是，一旦发送到express（使用axios）->控制台日志，req.body将显示未定义

form.js

<form onSubmit={this.props.handleSubmit((values) => { this.props.submitInvestment(values) })}>

export default connect(null, actions)(reduxForm({ form: 'investmentForm' })(InvestmentForm))

route.js

module.exports = app => {
  app.post('/api/investments', async (req, res) => {
    console.log(req.body)
    res.sendStatus(200);
  });
}

此外；当我试图用完整构建的route.js捕捉请求时

module.exports = app => {
  app.post('/api/investments', async (req, res) => {
    const { currency, units, date } = req.body;

    const investment = new Investment({ 
      currency,
      units,
      date,
      _user: req.user.id
    });

    try {
      await investment.save();
      res.status(200);
    } catch (err) {
      res.status(422).send(err);
    }
  });
}

那么我的服务器日志是

[0] (node:25154) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: Cannot match against 'undefined' or 'null'.
[0] (node:25154) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

传入的请求需要由中间件处理

App.js

app.use(bodyParser.json());

您是否包括

body解析器

中间件？正如在《仅为验证》中所述，您是否尝试过在服务器上发送带有

json.stringify（）

和

json.parse（）

的正文？@Daniele成功了，谢谢！
