body data not sent in axios request

问题:

I am trying to send data through axios request to my backend script, but the body looks empty.

Here's a request sent from front-end:

axios.request({
  method: 'GET',
  url: `http://localhost:4444/next/api`,
  headers: {
    'Authorization': token
  },
  data: {
    next_swastik: 'lets add something here'
  },

}).then((res)=>{  
  console.log("api call sucessfull",res);

}).catch((err)=>{
  console.log("api call unsucessfull",err);

  this.props.toggleLoading(false);
})

Here's a back-end:

app.get('/next/api', verifyToken, function(req, res) {
console.log(req.body);

})

But I am getting {} empty body. I am getting headers and other data but not data.

回答1:

GET requests should not have a body.

Change the method from 'GET' to 'POST'

Like so:

axios.request({
  method: 'POST',
  url: `http://localhost:4444/next/api`,
  headers: {
    'Authorization': token
  },
  data: {
    next_swastik: 'lets add something here'
  },

})

and change your api to expect a post

app.post('/next/api', verifyToken, function(req, res) {
console.log(req.body);
});

or

Change the data property to params

axios.request({
  method: 'GET',
  url: `http://localhost:4444/next/api`,
  headers: {
    'Authorization': token
  },
  params: {
    next_swastik: 'lets add something here'
  },

})

and change the api to log out the params

app.get('/next/api', verifyToken, function(req, res) {
console.log(req.params);
});

and like @MaieonBrix said, make sure that your headers contain the content type that you are sending.

It looks like you only have two points left to make it work :

• one : the http method should be set to POST instead of GET since you want to send something.

• two : you can then add the http header (like what you did with the authorization header) Content-Type: 'application/json`

On the back-end don't forget to use some kind of body parser utility package like this one : body-parser and set it up with your app.

I suppose your server is using express, here is how you will do it with express :

const express = require('express');
const app = express();
const bodyParser = require('body-parser')
const jsonParser = bodyParser.json();

app.use(jsonParser); // use it globally
app.get('your_route', jsonParser, otherMiddleware, (req, res) => ...); // use it for specific routes

/* ... rest of your code */

Try this

this.axios('realties', { params: this.filter })
