Express.js POST req.body empty

Question

So I have the following code in my server.js file that I\'m running with node.js. I\'m using express to handle HTTP requests.

app.post(\'/api/destinations\',         


        

Answer 1

You need bodyParser.json as well:

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

Answer 2

Sometimes the req.body shows {} if you forgot to put the name attribute to the form input fields. Following is an example:

<input type="email" name="myemail" class="form-control" id="exampleInputEmail2" placeholder="Email address" required>

Then the req.body shows { myemail: 'mathewjohnxxxx@gmail.com' }

I post this answer because, i have encountered the similar problem and this worked for me.

Answer 3

For me the back end was configured properly the issue was valid JSON format including double quotes on the variables.

this did not work

      const res = await axios.post(serverPath + "/user/login", {
         email: email,
         password: password,
      });

This DID work (with double quotes around email and password

      const res = await axios.post(serverPath + "/user/login", {
         "email": email,
         "password": password,
      });

Answer 4

Make sure if you are making the form and inputs in javascript that you append the input to the form. That was my issue.

yourForm.appendChild(yourInput);
