Passing headers with axios POST request

I have written an Axios POST request as recommended from the npm package documentation like:

var data = {
    'key1': 'val1',
    'key2': 'val2'
}
axios.post(Helper.getUserAPI(), data)       
.then((response) => {
    dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
    dispatch({type: ERROR_FINDING_USER})
})

And it works, but now I have modified my backend API to accept headers.

Content-Type: 'application/json'

Authorization: 'JWT fefege...'

Now, this request works fine on Postman, but when writing an axios call, I follow this link and can't quite get it to work.

I am constantly getting 400 BAD Request error.

Here is my modified request:

axios.post(Helper.getUserAPI(), {
    headers: {
        'Content-Type': 'application/json',
        'Authorization': 'JWT fefege...'
    },
    data
})      
.then((response) => {
    dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
    dispatch({type: ERROR_FINDING_USER})
})

Solution 1:

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
    })
  })

Solution 2:

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);
})

Solution 3:

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}`
  }
})
