Passing headers with axios POST request

Question

When using Axios, in order to pass custom headers, supply an object containing the headers as the last argument

Modify your Axios request like:

const headers = {
  'Content-Type': 'application/json',
  'Authorization': 'JWT fefege...'
}

axios.post(Helper.getUserAPI(), data, {
    headers: headers
  })
  .then((response) => {
    dispatch({
      type: FOUND_USER,
      data: response.data[0]
    })
  })
  .catch((error) => {
    dispatch({
      type: ERROR_FINDING_USER
    })
  })

Here is a full example of an axios.post request with custom headers

var postData = {
  email: "[email protected]",
  password: "password"
};

let axiosConfig = {
  headers: {
      'Content-Type': 'application/json;charset=UTF-8',
      "Access-Control-Allow-Origin": "*",
  }
};

axios.post('http://<host>:<port>/<path>', postData, axiosConfig)
.then((res) => {
  console.log("RESPONSE RECEIVED: ", res);
})
.catch((err) => {
  console.log("AXIOS ERROR: ", err);
})

To set headers in an Axios POST request, pass the third object to the axios.post() call.

const token = '..your token..'

axios.post(url, {
  //...data
}, {
  headers: {
    'Authorization': `Basic ${token}` 
  }
})

To set headers in an Axios GET request, pass a second object to the axios.get() call.

const token = '..your token..' 

axios.get(url, {
  headers: {
    'Authorization': `Basic ${token}`
  }
})

const data = {
  email: "[email protected]",
  username: "me"
};

const options = {
  headers: {
      'Content-Type': 'application/json',
  }
};

axios.post('http://path', data, options)
 .then((res) => {
   console.log("RESPONSE ==== : ", res);
 })
 .catch((err) => {
   console.log("ERROR: ====", err);
 })

All status codes above 400 will be caught in the Axios catch block.

Also, headers are optional for the post method in Axios
