backbone.jsHow do I set headers in Backbone.js?
Backbone.js provides a way to set headers for all requests made from the application. This can be done by setting the headers
property in the sync
method of the model or collection.
For example, if you want to set a Authorization
header on all requests, you can do the following:
MyModel = Backbone.Model.extend({
sync: function(method, model, options) {
options.headers = {
'Authorization': 'Bearer <token>'
};
return Backbone.sync(method, model, options);
}
});
The sync
method takes three parameters:
method
: The HTTP method to use for the request (e.g.GET
,POST
,PUT
, etc).model
: The model or collection that is being synced.options
: An options object containing the headers to be set.
The options
object is passed to the Backbone.sync
method, which is responsible for making the actual request.
You can also set headers on a per-request basis by passing the headers
option when calling sync
directly. For example:
MyModel.fetch({
headers: {
'Authorization': 'Bearer <token>'
}
});
