Question

我正在尝试使用axios post方法将数据发送到具有不同端口号的其他微服务。但是在其他微服务中，im无法获取/获取从服务A发送到服务B的数据。我如何在另一个微服务中获取firstname和lastname的值？我已经安装了body-parser，但仍然无法正常工作，在微服务之间通信/发送数据的最佳方法是什么？谢谢

Service A (Port 3001)

     axios.post('http://localhost:3000/v1/wsData', {
  firstName: 'Fred',
  lastName: 'Flintstone'
})
.then(function (response) {
  console.log(response);
})
.catch(function (error) {
  console.log(error);
});





Service B (Port 3000)


router.post('/v1/wsData',async(ctx, next) => { 
  try {
    const result =  ctx.response.firstName
    console.log(result)
    await next ()
  } catch(err) {
    throw err
  }
}
)

尝试了很多次后，我不断收到错误，例如数据未定义，没有对象等等

Answer 1

您在使用expressjs吗？

如果是这样，您可以使用app.use(express.json())或/和app.use（express.urlencoded({extended: boolean})作为正文解析中间件。

ctx是什么意思？

router.post('/v1/wsData', (req, res, next) => {
    //you can access the body with req.body.
});

您是否在下一个中间件中发送响应？如果没有，则可以使用res.send，res.json（），res.sendStatus（），....

我希望能有所帮助。

在使用axios POST请求发送数据以及在另一个微服务中获取/获取数据时需要帮助
