Setting up vue-resource root and authentication configuration

Currently, I am reviewing the documentation for vue-resource that outlines how to configure it: https://github.com/vuejs/vue-resource/blob/master/docs/config.md

The documentation specifies setting headers with a common authorization value:

 Vue.http.headers.common['Authorization'] = 'Basic YXBpOnBhc3N3b3Jk';

While it seems like "Basic YXBpOnBhc3N3b3Jk" is just an example, what exactly does this value signify and what should be used instead?

Additionally, on the same page, there is mention of a "root" setting:

 Vue.http.options.root = '/root';

I interpret this as the base URL for the web application. Nonetheless, why does vue-resource require me to provide this information? What purpose does it serve?

javascriptvue.jsvue-resource

Answer №1

When you add headers to the Vue.http.headers.common object, vue-resource will include these headers in every request.

If you want to add headers to each individual request, you can do so like this:

http({
 url: '/someUrl', 
 method: 'GET',
 headers: {
   Authorization: 'Basic YXBpOnBhc3N3b3Jk'
 }
})

The value for the Authorization header is a base64-encoded string with a username and password combination. 

window.atob('YXBpOnBhc3N3b3Jk') // => "api:password"

If you need to use basic authentication with vue-resource, make sure to provide your own username and password.

Keep in mind that anyone using your application can potentially see the username and password. Check out https://en.wikipedia.org/wiki/Basic_access_authentication for more details on basic authentication.

You can set the root endpoint for your REST service by defining the root-property.

Vue.http.options.root = 'http://api.domain.com/v1'

// This will send the request to http://api.domain.com/v1/someRoute
http({
 url: '/someRoute'
});

Answer №2

To globally set header authorization, utilize the interceptor:

Vue.http.interceptors.push(function(request, next) {

    request.headers['Authorization'] = 'Basic abcd' //Base64
    request.headers['Accept'] = 'application/json'
    next()
});

Additionally, remember to enable credentials by using the following option:

Vue.http.options.credentials = true;
