Unhandled Rejection (SyntaxError): Unexpected end of JSON input

I have a login form (Username and Password) written in a React JS environment; the form consumes a REST API that contains the user credentials. I'm using the Fetch method to consume the API, but it errors out. I need to access the service via POST, but when I check (via chrome console - Network tab ) how my application is accessing the service, it states that the request method used is GET. How do I modify my code to access the form using post? Here is my code snippet I'm using to consume the web APT:

class Login extends Component {

    //constructor
    constructor() {
        super();
        this.state={
         data: [],
        }
    } 

    //componet did mount method
    componentDidMount(){
        return fetch('http://myjson.com/file')
        .then((response)=>response.json())
        .then((responseJson)=>
        {

           this.setState({
               data:responseJson.token
           })
           console.log(this.state.data)
        })
   }

I researched using the request.method but I'm uncertain how to implement it into the code. Could I get some help with this please? ...thanks in advance

fetch('http://myjson.com/users/', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    username: 'userName',
    password: 'pwd',
  })
})

Here is fetch docs

Edit

componentDidMount(){

    return fetch('http://myjson.com/users/', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        username: 'userName',
        password: 'pwd',
      })
    })
    .then((response)=>response.json())
    .then((responseJson)=>
    {

       this.setState({
           data:responseJson.token
       })
       console.log(this.state.data)
    })
}
