responseType can be 'arraybuffer', 'blob', 'document', 'json', 'text', 'stream'.

In this example, this.data is the data you want to send. It can be a value or an Array.

Passing an object argument

(If you want to send an object you'll probably have to serialize it). You can initialize a default header axios.defaults.headers. Morris SMorris S. if you want to do a get request with params and headers.

I have changed like this in axios header. I had to create a fd=new FormData() object and use the [.append()][1] method before sending it through axios to my Django API, otherwise I receive a 400 error.In my backend the profile image is related through a OneToOne relationship to the user model.

Therefore it is serialized as a nested object and expects this for the put request to work. All changes to the state within the frontend are done with the this.setState method.

I believe important part is the handleSubmit method at the end. First my axios put request:. My handleSubmit method needs to create the following json object, where the image attribute gets replaced by the actual user input:.

Multiple requests

@user2950593Your axios request is correct. You need to allow your custom headers on server side.If you have your api in php then this code will work for you.

Once you will allow your custom headers on server side, your axios requests will start working fine.

You can use axios interceptors for this task. 1-) Inside the successfull login, put the retrieved token to the localStorage. Remove setAuthToken line. 2-) Add this interceptor to your axios instance.

The code snippet below does not working (but it does not raise any error); global header is used when using the instance:.

Using Axios interceptors

This does work, instance header overrides the global default:. It seems to me that this object structure should be created by default when using #create. Additionally, if you want to unset the header don't use delete.

We can use Axios interceptors to automatically set the Authorization header for all requests:

In this example, we use the axios.interceptors.request.use method to update each request header and set the access token in the Authorization HTTP header.

We target the Authorization header from the config.headers object and set a Bearer token, which is stored in localStorage, as its value.

Axios interceptors are also useful for monitoring access tokens for impending expiration. A refreshToken() function may be used to update a token before it expires:

We can also call the axios.interceptors.response.use() method to get a new access token whenever a response returns a 403 error, meaning the existing token has expired:

In this example, the axios.interceptors.response.use method intercepts all incoming responses and then checks the status of the response. If the request that triggered the response is not authenticated, then the token is expired. In that case, we call for the refreshToken() function to obtain a new access token.

Wrapping up

In this article, we examined how to set HTTP request headers with Axios by passing an object, creating a specific Axios instance, and using Axios interceptors. For information about additional features of the Axios HTTP client, see its website or GitHub.

Are you adding new JS libraries to improve performance or build new features? What if they’re doing the opposite?

There’s no doubt that frontends are getting more complex. As you add new JavaScript libraries and other dependencies to your app, you’ll need more visibility to ensure your users don’t run into unknown issues.

LogRocket is a frontend application monitoring solution that lets you replay JavaScript errors as if they happened in your own browser so you can react to bugs more effectively.

LogRocket works perfectly with any app, regardless of framework, and has plugins to log additional context from Redux, Vuex, and @ngrx/store. Instead of guessing why problems happen, you can aggregate and report on what state your application was in when an issue occurred. LogRocket also monitors your app’s performance, reporting metrics like client CPU load, client memory usage, and more.
