web.fetch.Headers — clojure-interop/cljs-web-api 1.0.10

The Headers interface of the Fetch API allows you to perform actions on HTTP request and response headers. These actions include setting, adding to, and removing. A Headers object has an associated list, which is initially empty and consists of zero or more name value pairs. You can add to this using methods like append() Examples.) In all methods of this interface, header names are by case-insensitive byte sequence.

append cljs

(append this name value)

Method.

The append() method of the web.fetch.Headers interface appends new value onto an existing header inside a Headers object, or the header if it does not already exist.

myHeaders.append(name, value);

constructor cljs

(constructor & args)

Constructor.

The Headers() constructor creates a new web.fetch.Headers object.

init Optional An object containing any HTTP headers that you want to pre-populate your Headers object with. This can be a simple object literal with web.ByteString values; or an existing Headers object. In the last case, the new Headers object inherits its data from the existing Headers object.

delete cljs

(delete this name)

Method.

The delete() method of the web.fetch.Headers interface deletes header from the current Headers object.

myHeaders.delete(name);

entries cljs

(entries this)

Method.

The Headers.entries() method returns an iterator allowing to through all key/value pairs contained in this object. The both key and value of each pairs are web.ByteString objects.

headers.entries();

for-each cljs

(for-each this & args)

Method.

Executes a provided function once for each array element.

get cljs

(get this name)

Method.

The get() method of the web.fetch.Headers interface returns byte string of all the values of a header within a Headers object a given name. If the requested header doesn't exist in the Headers it returns null.

myHeaders.get(name);

get-all cljs

(get-all this name)

Method.

[Experimental] [Obsolute]

The getAll() method of the web.fetch.Headers interface used return an array of all the values of a header within a Headers with a given name; in newer versions of the Fetch spec, it has deleted, and Headers.get() has been updated to fetch all header instead of only the first one.

myHeaders.getAll(name);

has cljs

(has this name)

Method.

The has() method of the web.fetch.Headers interface returns boolean stating whether a Headers object contains a certain header.

myHeaders.has(name);

keys cljs

(keys this)

Method.

The Headers.keys() method returns an iterator allowing to go all keys contained in this object. The keys are web.ByteString

headers.keys();

set cljs

(set this name value)

Method.

The set() method of the web.fetch.Headers interface sets a value for an existing header inside a Headers object, or adds header if it does not already exist.

myHeaders.set(name, value);

values cljs

(values this)

Method.

The Headers.values() method returns an iterator allowing to through all values contained in this object. The values are web.ByteString

headers.values();
