Django响应将json设置为cookie

Question

I would like to set the value of a client side cookie from django as a javascript dictionary object. I know you can set a cookie value of a string like this in django:

response = HttpResponseRedirect( reverse('app:home') )
response.set_cookie( 'cookiekey', 'value' )
return response

I can then read the cookie on the client side like this:

Cookies.get( 'cookiekey' )

using the Cookies library ( https://github.com/js-cookie/js-cookie )

What I am unable to do is set the cookie to be a dictionary/json object:

I have tried this:

response.set_cookie( 'cookiekey', {'value' : 'value'} )

and

import json
response.set_cookie( 'cookiekey', json.dumps( {'value' : 'value'} ) )

and then tried to read the cookie back on the client side using:

Cookies.getJSON( 'cookiekey' )

but this doesn't seem to give me back a javascript dictionary object (neither does Cookies.get) but instead a string:

var message = Cookies.getJSON( 'cookiekey' );
alert( typeof message );

Answer 1

Use this in your Python script to set the cookie:

response.set_cookie("json", json.dumps({"foo":"bar"}))

And use this in your JavaScript to get the cookie, using JSON.parse rather than Cookies.get :

JSON.parse(Cookies.get( 'json' ))

This worked for me :)

EDIT:

Use JSON.parse(Cookies.get( 'json' ).split('\\\\').join(''); to remove all backslashes if that's an issue
