1 00:00:00,210 --> 00:00:07,320 All right, and before we implement the longer functionality in our interceptor and as a result in our 2 00:00:07,320 --> 00:00:09,780 application, let's discuss quickly why. 3 00:00:10,170 --> 00:00:16,980 So when I'm trying to update some user data, if one of the barriers is missing, I'm getting back this 4 00:00:16,980 --> 00:00:20,310 400, which means, well, it's a bad request. 5 00:00:20,730 --> 00:00:27,540 So essentially, user either needs to add the correct value or he or she just needs to navigate to the 6 00:00:27,780 --> 00:00:28,350 other page. 7 00:00:28,350 --> 00:00:33,960 And then when they come back normal again, this is going to be the default value that is coming from 8 00:00:33,960 --> 00:00:34,560 the database. 9 00:00:35,010 --> 00:00:35,970 Hopefully, that is clear. 10 00:00:36,620 --> 00:00:40,020 Now what would be other possible errors that we get? 11 00:00:40,200 --> 00:00:47,070 Well, we could get five hundred, which is that generic server error, but we can also get for a one 12 00:00:47,670 --> 00:00:48,480 one two four one. 13 00:00:48,930 --> 00:00:51,720 Well, that is unauthorized, correct? 14 00:00:52,290 --> 00:00:56,820 And here's what we need to think about if we're heading here for a one. 15 00:00:57,660 --> 00:01:00,330 Should the user be in the application in the first place? 16 00:01:01,110 --> 00:01:03,060 And what would be the scenario? 17 00:01:03,090 --> 00:01:08,040 Well, the scenario is that, let's say, user logged in and everything is fine and dandy. 18 00:01:08,040 --> 00:01:11,220 But at some point the token expired. 19 00:01:11,940 --> 00:01:15,750 Wouldn't it make more sense if we get back for a one? 20 00:01:16,050 --> 00:01:21,300 We actually log out the user right instead of just displaying that there's an error. 21 00:01:21,300 --> 00:01:28,200 So let me showcase that I'm going to go back to my app context and I'll do the same thing like we already 22 00:01:28,200 --> 00:01:31,710 did in one of the previous videos where I'm just going to comment on the token. 23 00:01:32,040 --> 00:01:37,470 Now again, keep in mind what I'm trying to showcase here is the Aspire token. 24 00:01:38,280 --> 00:01:40,200 I just don't want to go through the server and all that. 25 00:01:40,410 --> 00:01:45,240 But the idea is going to be exactly the same way if this token is not present. 26 00:01:45,630 --> 00:01:49,080 What we're going to get back is not the 400 show. 27 00:01:49,080 --> 00:01:55,620 We will get the 401 and in here now, even with all the values providing all that, I'm going to get 28 00:01:55,620 --> 00:01:57,120 this authentication round. 29 00:01:57,510 --> 00:02:01,980 And again, let me address the question one more time. 30 00:02:02,700 --> 00:02:06,210 What do you think makes more sense if you get four to one? 31 00:02:06,900 --> 00:02:08,400 So essentially, you're not authorized? 32 00:02:08,759 --> 00:02:15,240 Does it make sense to display that or kick out the user and then make sure that he or she logs back 33 00:02:15,240 --> 00:02:15,420 in? 34 00:02:15,630 --> 00:02:20,970 And of course, the answer is the second one where essentially you want to log out the user and make 35 00:02:20,970 --> 00:02:23,430 sure that all the credentials are in place. 36 00:02:23,730 --> 00:02:24,630 Now, how do we do that? 37 00:02:24,660 --> 00:02:28,230 Well, remember, we have right now our request and all that. 38 00:02:28,590 --> 00:02:30,090 I mean, everything is beautiful. 39 00:02:30,090 --> 00:02:36,180 We can save it here and make sure that we have the token and where we have the response. 40 00:02:36,180 --> 00:02:43,800 One, instead of just logging, what is the functionality for us that does the long, hard slog out 41 00:02:43,800 --> 00:02:44,690 user correct? 42 00:02:45,120 --> 00:02:52,320 So we're keeping score and keep on scrolling somewhere here who have the user dispatch, as well as 43 00:02:52,320 --> 00:02:56,670 removal from the local storage and instead of just logging something. 44 00:02:57,590 --> 00:03:02,150 The off air or whatever, I actually want to invoke dysfunction. 45 00:03:02,420 --> 00:03:06,590 I want to go here with logout user and invoke it. 46 00:03:06,890 --> 00:03:07,310 You know what? 47 00:03:07,700 --> 00:03:11,480 I think I was in too much of a hurry, actually. 48 00:03:11,960 --> 00:03:13,010 Still want to showcase this? 49 00:03:13,310 --> 00:03:13,940 My apologies. 50 00:03:14,090 --> 00:03:17,930 So now let's notice something where I'm going to go back to my application. 51 00:03:18,050 --> 00:03:19,300 All the values are here. 52 00:03:19,310 --> 00:03:20,300 Everything is correct. 53 00:03:20,570 --> 00:03:25,550 But since I have the token missing, I will be logged out as I should be. 54 00:03:25,850 --> 00:03:32,120 Now, one thing that I kind of want to quickly mention is the fact that we'll still display this arrow 55 00:03:32,120 --> 00:03:37,550 here, the alert, or simply because I mean, it takes time for us to remove it. 56 00:03:37,910 --> 00:03:38,270 Correct. 57 00:03:38,300 --> 00:03:40,370 Remember, we were doing that delay thing. 58 00:03:40,610 --> 00:03:44,700 So let me just quickly show cause that where I'm going to go with email. 59 00:03:44,720 --> 00:03:47,690 And if I remember correctly, it was Susan now. 60 00:03:47,960 --> 00:03:50,000 Now I believe my password is still secret. 61 00:03:50,390 --> 00:03:52,100 Hopefully, I didn't mess that one up. 62 00:03:52,430 --> 00:03:57,650 And again, let me quickly show something more once I go here and then I go to register notice. 63 00:03:57,980 --> 00:04:01,310 You'll get this alert for a little bit because we have that delay. 64 00:04:01,580 --> 00:04:02,900 Now, why am I showing that? 65 00:04:03,230 --> 00:04:08,570 Not only what I want to do is log out user here if it is for one? 66 00:04:09,710 --> 00:04:13,370 I also want to go to my update user over here. 67 00:04:13,730 --> 00:04:18,890 And I actually want to dispatch this one only if it's not for one. 68 00:04:19,370 --> 00:04:23,890 So essentially, if it's for one, I mean, there's really no point to showing that alert, correct 69 00:04:24,110 --> 00:04:28,250 and how we can do that while we're here, I can just set up the if condition where I'm going to go with 70 00:04:28,250 --> 00:04:33,320 error, then that response response status. 71 00:04:33,560 --> 00:04:38,750 And I'll just say, if it's not for one, then display there otherwise. 72 00:04:38,750 --> 00:04:40,430 I mean, you don't have to do anything. 73 00:04:40,820 --> 00:04:47,120 And yes, to answer your question, you can also attach, for example, five hundred in the log out 74 00:04:47,330 --> 00:04:48,200 as well as here. 75 00:04:48,500 --> 00:04:49,580 I mean, that kind of makes sense. 76 00:04:49,850 --> 00:04:55,120 If the server is not working properly, the user shouldn't be sitting in the front me anyway. 77 00:04:55,400 --> 00:04:56,480 So I'm going to go over here. 78 00:04:56,510 --> 00:05:00,710 I'll say if it's not for one, and then let's take this one over here. 79 00:05:01,010 --> 00:05:01,940 Let's say it. 80 00:05:02,240 --> 00:05:05,180 And now let's go back to our front end application one more time. 81 00:05:05,450 --> 00:05:07,330 So let me quickly log in again. 82 00:05:07,340 --> 00:05:09,020 I know you're probably sick of this, but. 83 00:05:10,030 --> 00:05:10,780 Mean, just do that. 84 00:05:11,170 --> 00:05:16,990 I'm going to go here, I'm going to log in again, I'll provide all the values, so that should be correct. 85 00:05:17,510 --> 00:05:23,320 And then let me go and I'll quickly show that there is an alert in this case. 86 00:05:23,590 --> 00:05:29,590 Again, you might say it's an extra step, but in my opinion, since we're setting up that delay, it 87 00:05:29,590 --> 00:05:32,140 kind of makes sense over here that we're not displaying the alert. 88 00:05:32,560 --> 00:05:36,970 Again, let me repeat, if there would be no delay, this wouldn't be necessary. 89 00:05:37,240 --> 00:05:38,060 Well, right away. 90 00:05:38,080 --> 00:05:39,190 Log out the user. 91 00:05:39,490 --> 00:05:45,070 So that way there's not going to be sending that message over there because keep in mind that we set 92 00:05:45,070 --> 00:05:51,520 this up and then there's that delay for us to remove in my case right away, just remove it when we 93 00:05:51,520 --> 00:05:52,360 invoke the function. 94 00:05:52,630 --> 00:05:54,190 Hopefully, that makes sense. 95 00:05:54,400 --> 00:05:59,920 And before we start setting up the jobs in our application, so essentially, we'll start with the model. 96 00:05:59,920 --> 00:06:02,560 We set up the controller and you already know the drill. 97 00:06:03,010 --> 00:06:08,890 I also want to clean up the app context a little bit where I will comment out of this log. 98 00:06:09,370 --> 00:06:11,860 So essentially, if you want to keep it, it's definitely an option. 99 00:06:11,860 --> 00:06:14,110 In my case, I will comment this one out. 100 00:06:14,110 --> 00:06:18,280 I will uncomment the Birtukan you the request one. 101 00:06:18,460 --> 00:06:22,930 So this one was in response, more specifically in the error callback function. 102 00:06:23,260 --> 00:06:27,010 Now this is going to be in the request one in the callback function. 103 00:06:27,370 --> 00:06:31,690 So a definitely, definitely definitely want to add that token over here. 104 00:06:32,050 --> 00:06:32,890 And then remember. 105 00:06:33,850 --> 00:06:36,270 In a profile, we comment this one, correct. 106 00:06:36,520 --> 00:06:39,280 While we were testing well, we're done with testing. 107 00:06:39,670 --> 00:06:45,460 Just keep in mind that from this point on, we'll be checking for those antibodies right away in the 108 00:06:45,460 --> 00:06:45,740 front. 109 00:06:46,720 --> 00:06:52,930 So if you all try to test the for hire response, I mean, it's not going to work because we'll right 110 00:06:52,930 --> 00:06:56,560 away check for it or we're here and with these changes in place. 111 00:06:56,860 --> 00:06:59,200 Now we can start setting up jobs in our application.
