In HTTP, a PUT request is a method used to update a resource on a web server. This indicates that a client is putting a new version of a resource to a specific URL path. Axios is a popular JavaScript library used for making HTTP requests in a browser. In this article, we will explore how to use the Axios library to perform PUT requests with headers, along with code examples.
Headers are used to communicate metadata information about a request or response. HTTP headers help in identifying the type of content being sent, language preferences, caching preferences, and more. Headers are also used to authenticate a request or to provide additional information. Axios allows for the use of headers during HTTP requests to include additional details and information for the server or client as needed.
To send a PUT request with headers using Axios, we must first install the library through NPM. You can do this by running the command npm install axios in your terminal. Once installed, we can import Axios and use it to make a PUT request with headers.
To make a PUT request using Axios, we can use the axios.put() method. The first parameter for this method is the URL to which we want to make the request. Following this, we can pass in an object containing the headers using the headers key. The object should contain key-value pairs representing the header name and its value. Finally, we can pass in the data we want to update as the third parameter.
Example:
import axios from 'axios';
const URL = 'https://myapi.com/resource';
const data = {
name: 'John Doe',
age: 30,
};
const headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer MY_TOKEN_HERE',
};
axios.put(URL, data, { headers })
.then(response => {
console.log(response.data);
})
.catch(error => {
console.error(error);
});
In this example, we are making a PUT request to https://myapi.com/resource. The data object contains the information we want to update for the resource. We also defined the headers object with the Content-Type and Authorization headers. These headers will be sent along with the request to provide additional information.
Once the request is sent, we then listen for the response using a .then() function. This function receives the response object from the server, which contains the updated resource data. In case of any errors or failures, we also have a .catch() function to handle the errors.
In conclusion, making PUT requests with headers using Axios is a straightforward process. We simply need to define the headers object and pass it as an argument to the axios.put() method. With Axios, we can easily make HTTP requests, including GET, POST, PUT, DELETE, and more, using JavaScript.
in this article, we will explore the use of Axios library along with PUT method and headers to make web requests. We will cover some of the important HTTP headers used to authenticate a PUT request, authenticating a PUT request with Bearer Tokens, and many more.
PUT request is the most popular method for updating the resources at the server-side in the RESTful APIs and web development. We use the PUT method when our data is structured and requires an update. This method performs a full update on the server-side.
Axios is a popular and widely used JavaScript library for performing HTTP requests from a web page. Axios provides us with a streamlined and simplified API for sending HTTP requests and handling responses.
Headers are used to transmit information about the HTTP request or response, such as the type of content, language preferences, and authentication information. Headers allow us to customize our HTTP requests based on our specific application needs.
To send a PUT request using Axios, we start by installing the library via NPM. Once installed, we can create a new instance of the Axios client using the axios.create() method and specify the default headers to be sent with each request.
import axios from 'axios';
const baseURL = 'https://api.example.com';
const instance = axios.create({
baseURL,
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer MY_TOKEN_HERE',
},
});
In this example, we created an instance of axios and specify the base URL for the API. We also specified the default headers to be sent with each request using the headers key. Here, we defined the Content-Type and Authorization headers that will be sent with every request.
We can then use this instance to make a PUT request by calling the put() method and passing in the URL, data, and any additional headers as needed.
const data = {
name: 'John Doe',
age: 30,
};
const headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer MY_TOKEN_HERE',
};
instance.put('/resource/123', data, { headers })
.then(response => {
console.log(response.data);
})
.catch(error => {
console.error(error);
});
In this example, we made a PUT request to a resource 123 with the given data. We also passed in the headers object to include any additional headers needed for the request.
When it comes to authentication, Bearer Tokens are a popular method for authenticating HTTP requests. A Bearer Token is an authentication mechanism that involves passing a token along with the request to authenticate the user or client.
To authenticate a PUT request using Bearer Tokens, we need to include the token as an Authorization header in the request.
const data = {
name: 'John Doe',
age: 30,
};
const token = 'MY_BEARER_TOKEN';
const headers = {
'Content-Type': 'application/json',
'Authorization': `Bearer ${token}`,
};
instance.put('/resource/123', data, { headers })
.then(response => {
console.log(response.data);
})
.catch(error => {
console.error(error);
});
In this example, we include the bearer token as an Authorization header by concatenating the token with the string Bearer. The server can then extract the token from the header using a server-side code and use it to authenticate the request.
In conclusion, Axios is a powerful and popular library for sending HTTP requests from a web page. With its streamlined and simplified API, Axios makes it easy to handle HTTP requests and responses with minimal setup and minimum effort. By including headers in the request, we can customize our HTTP requests to include additional information like authentication tokens, cookies or caching information.
