Is !document.cookie reliable?

由 天大地大妈咪最大 提交于 2020-01-02 01:21:08
问题 I'm wondering if using the following Javascript code is reliable: if (!document.cookie) { alert('Cookies are disabled.'); } I've tested this in IE, Firefox and Chrome and it seems that when you disabled cookies, the document.cookie object becomes unavailable. Does anyone have any experience with this method working/not working? Many Thanks Stephen Additional I'm well aware that this method requires JavaScript to be enabled on the client. I'm also aware of other server-side/JavaScript

问题 I am trying out Google Colab, but then I keep getting this pop up box that says: Error Could not access the resources needed to display output. This is probably because third-party cookies are not allowed by your browser. NotSupportedError: Failed to register a ServiceWorker: The user denied permission to use Service Worker. While turn off Block third party cookies worked for me from here, I would like to keep the setting to be turned on at all times for the sake of our privacy. Currently I

iPhone App Cookie Delay

由 て烟熏妆下的殇ゞ 提交于 2020-01-01 19:18:13
问题 My iPhone app has a UIWebView that loads a page containing javascript that sets a cookie. It seems that if i set a cookie and exit the app within 10-15 seconds then the cookie is never saved, however if i set the cookie, wait 10-15 seconds THEN exit the app, the cookie is saved. Anyone have any info about why their is a delay and how to go about having the cookies saved immediately. 回答1: The only workaround i was able to come up with is to save the cookies to the user defaults right before

Is this an appropriate login and registration encryption system

由 旧巷老猫 提交于 2020-01-01 12:25:34
问题 Apparently, hashing the username and password and saving them as cookies and logging in with sanitized cookie data is not good enough for you people (or my site's safety). Is this approach good enough? Registration procedure: $salt= date('U'); $username= hash('sha256', $salt. $_POST['username']); $password= hash('sha256', $salt. $_POST['password']); $token = hash('sha256', $salt. (rand(1,10000000000000000000000000000000000000000000))); To login manually, users type in their username and

Chrome does not allow cookies with expirations less than 4 hours

由 霸气de小男生 提交于 2020-01-01 12:24:10
问题 I can't seem to set cookies with short lifespans in Google Chrome. They're either not getting set, or are immediately being deleted (can't tell which, although the result is the same either way). This only occurs if the expiration is 4 hours or less in the future. Identical code works fine if the expiration time is greater than 4 hours and the issue does not occur in Firefox or Safari. Here's an example: Does not work: exp = new Date(); exp.setMinutes(exp.getMinutes() + 240); document.cookie=

Save OAuth WRAP access tokens directly on client machine in a cookie?

由 不想你离开。 提交于 2020-01-01 12:07:50
问题 I'm planning to setup a website that would access an oauth wrap framework. I was thinking of storing the access token on the client machine as it is. I do NOT want to maintain a database of temporary tokens, etc on the server. Should I be doing do? Or should I encrypt it? 回答1: First, why are they not using OAuth 2.0... You can store the OAuth credentials in a cookie or better yet, in HTML5 local storage. It should be encrypted so that only the server has access to this cookie and only the
