WEBVTT 00:05.140 --> 00:05.740 I have read on. 00:05.740 --> 00:06.650 Welcome back. 00:06.760 --> 00:11.010 So in this final year we're going to be testing the API that we've been developing. 00:11.130 --> 00:13.170 So a couple of things from the previous video. 00:13.180 --> 00:19.050 Basically copied all the files in this file over here and I've moved them into the tutorial once since 00:19.060 --> 00:20.690 we already finished it. 00:20.740 --> 00:26.590 And the reason I did that is because this tutorial one file already has most of the libraries like flask 00:26.590 --> 00:31.810 and stuff like that and flask trustful so we don't have to download them again from scratch but you 00:31.810 --> 00:36.520 can do whatever I do right now and this similar similarity class file. 00:36.520 --> 00:36.760 Right. 00:36.760 --> 00:40.860 So you don't have to copy this into the tutorial one folder. 00:40.870 --> 00:44.220 I just moved it so I don't have the internet connection isn't very good. 00:44.290 --> 00:45.870 So I've just copied it there too. 00:45.870 --> 00:52.720 So that docket composed can cache some of the previously downloaded libraries and instead of downloading 00:52.720 --> 00:55.650 it again from scratch you can just access it from there. 00:55.670 --> 00:58.030 OK so I'm gonna go to tutorial one. 00:58.030 --> 01:01.860 But if you've been following so far then so. 01:01.970 --> 01:06.010 So go back and then go to tutorial one. 01:06.310 --> 01:11.560 And then if you've been following software you can pretend that you're inside text simulator and so 01:11.560 --> 01:14.650 if you open here it is exactly the same file. 01:14.650 --> 01:16.130 Everything's the same. 01:16.180 --> 01:18.630 The ACT-UP why file is the same. 01:18.650 --> 01:22.350 Right so this is what we've been writing registering detect and Riso. 01:22.540 --> 01:27.190 So this API is exactly what you've been writing in the whole file structures to see. 01:27.220 --> 01:30.300 So just pretend that you're indexing of it. 01:30.670 --> 01:35.760 So the first thing we're going to do is to do Sunar Dharker compose built. 01:36.430 --> 01:38.420 So we're going to build the project. 01:38.980 --> 01:43.800 So you'll see that it is going to OK. 01:43.810 --> 01:48.610 So I need to copy first of all this file because it's not excitatory or. 01:48.610 --> 01:51.160 So that's the only thing I haven't copied it yet. 01:51.510 --> 01:56.620 So I'm going to copy this file here that the model that we use in space. 01:56.790 --> 01:57.820 And I'm going to do. 01:57.910 --> 02:04.870 So let's first clear and then we're going to do Sudhakar composed build a gate is going to build them 02:04.870 --> 02:11.130 all I was going to tell me successfully built the model and the next thing I'm going to do is to shoot 02:11.140 --> 02:17.130 her dog her compose up and then I'm going to. 02:17.240 --> 02:21.630 So it should be running now and then you'll see it's running on localhost. 02:21.680 --> 02:22.820 So OK. 02:23.060 --> 02:26.620 So let's now open post man again. 02:29.040 --> 02:36.350 So we're going to open those men and in the meantime let's open the API to see how we expect the input 02:36.350 --> 02:36.710 to be. 02:36.710 --> 02:37.290 OK. 02:37.490 --> 02:42.370 So we come here and I'm going to say pseudo atom here. 02:42.370 --> 02:44.250 So I want to open the atom here. 02:45.310 --> 02:46.070 OK. 02:46.570 --> 02:49.850 So now it has been OK so this is active him over here. 02:49.870 --> 02:51.550 This is our API. 02:51.850 --> 02:53.070 It's at slash. 02:53.080 --> 02:55.120 So let's close this here. 02:55.360 --> 02:57.340 So this is our application. 02:57.340 --> 03:03.460 So the first thing is for the registration right so we go at slash register and it's expecting a username 03:03.460 --> 03:04.180 and password. 03:04.230 --> 03:04.970 OK. 03:05.230 --> 03:09.130 So I'm going to come to post Matt and then I'm going to write. 03:09.180 --> 03:18.280 Let's go to body and lead that and then just go to local hosta 5:7 slash register. 03:18.730 --> 03:28.510 And then from here let's say I have a Jaisalmer that I send a user name as a rule cause of my name and 03:28.600 --> 03:29.940 password. 03:30.220 --> 03:32.890 I'm going to write my password as 2:59 great. 03:32.920 --> 03:34.990 Very very simple password. 03:35.120 --> 03:39.260 And so I'm going to send this to so that I can register in the AP. 03:39.260 --> 03:41.630 I'm going to send this. 03:41.820 --> 03:48.150 And then there is the response status 202 I successfully signed up for the right for the message you 03:48.150 --> 03:50.280 successfully signed up for the API. 03:50.490 --> 03:50.880 Great. 03:50.880 --> 03:53.460 So now I have registered for the API. 03:53.670 --> 03:56.180 So now I'm going to be comparing. 03:56.190 --> 04:02.790 So if I go to the second thing is detect right and detect expects a username password. 04:02.790 --> 04:04.220 Text 1 and text 2. 04:04.320 --> 04:05.090 OK. 04:05.400 --> 04:10.220 So when I go back to postman and then I'm going to write karma. 04:10.350 --> 04:12.400 So I have a user name and my password. 04:12.510 --> 04:14.800 But this time I'm going to give it the next one. 04:14.910 --> 04:19.690 As for example this is a cute dog. 04:19.940 --> 04:20.580 OK. 04:22.470 --> 04:29.060 And then free text do I'm going to write Wow what a cute dog. 04:29.100 --> 04:29.650 OK. 04:29.850 --> 04:31.060 So they're very similar right. 04:31.070 --> 04:37.370 They're saying or for example I can write the dog is so cute. 04:37.410 --> 04:38.160 OK. 04:38.400 --> 04:40.370 So I'm saying one this is a cute dog. 04:40.380 --> 04:43.990 And wow the dog is so cute and it's funny. 04:44.220 --> 04:48.850 And that is going to tell me how close these two techs are or how similar they are. 04:48.850 --> 04:52.350 So police should give us a relatively high number. 04:52.350 --> 04:58.180 Right so not exactly one because there are different sentences obviously but they're also very similar. 04:58.170 --> 04:58.410 Right. 04:58.420 --> 05:00.230 They relate to each other. 05:00.540 --> 05:08.410 OK so let's try to use the service or send text and it tells me it's an invalid username. 05:08.570 --> 05:09.960 That's interesting. 05:10.330 --> 05:11.150 OK I see. 05:11.150 --> 05:13.500 So we haven't changed flash registers. 05:13.550 --> 05:15.550 This should be slashed tact. 05:15.740 --> 05:16.380 OK. 05:16.520 --> 05:18.370 So not register. 05:18.470 --> 05:23.130 So that's why it's telling me an invalid username because my user name is already taken. 05:23.130 --> 05:24.660 So he tells me choose another one. 05:24.740 --> 05:31.260 But we want to detect and not involve user ID and not register. 05:31.290 --> 05:32.770 OK so we're going to send this again. 05:32.780 --> 05:34.320 This is on file again. 05:34.580 --> 05:36.820 And then your notice here that it tells me. 05:36.850 --> 05:38.800 Let's see if I can make it bigger. 05:38.810 --> 05:40.070 Not quite. 05:40.340 --> 05:40.880 Exactly. 05:40.880 --> 05:48.140 Postman you would notice here tells me similarity score calculator successfully ratio is 0.66 5. 05:48.290 --> 05:51.010 So it's close to one race not super far away. 05:51.080 --> 05:55.630 So you can think of it as this is sixty six point five percent. 05:55.910 --> 05:56.360 Similar. 05:56.360 --> 06:00.950 So these two sentences are sixty six point five percent similar and that's fair enough. 06:00.950 --> 06:01.930 Right. 06:02.000 --> 06:06.790 They're talking about the same thing but not necessarily in the same format right. 06:06.800 --> 06:11.930 So this is the similarity between them and then status is still on. 06:11.960 --> 06:14.510 So what about if we change for example you too. 06:14.510 --> 06:15.350 Beautiful. 06:15.410 --> 06:16.330 Beautiful. 06:16.430 --> 06:16.940 OK. 06:17.120 --> 06:20.330 With that be changed the score obviously too good. 06:20.390 --> 06:23.050 So now it's sixty two point two percent. 06:23.330 --> 06:29.720 But you can still see that even though I changed it from cute to beautiful it still knows the similarity. 06:29.720 --> 06:29.870 Right. 06:29.870 --> 06:32.420 And this is the power of natural language processing. 06:32.450 --> 06:33.090 Right. 06:33.110 --> 06:37.840 It's able to do find that these two sentences are similar even though I don't. 06:37.940 --> 06:43.260 So I only have this dog right dog here that is that are exactly the same. 06:43.280 --> 06:48.810 But the sentences are two different sentences but it still finds the similarity is 62 percent. 06:48.830 --> 06:50.580 And that's pretty pretty cool. 06:50.590 --> 06:51.750 Right. 06:52.550 --> 06:55.460 OK so what happens if I keep abusing the system right. 06:55.520 --> 06:57.020 I use all my six tokens. 06:57.020 --> 07:03.450 I want to keep sending requests keep sending requests keeps running until I run out of tokens. 07:03.500 --> 07:05.930 So you can test the last gig. 07:06.140 --> 07:07.170 Oh yeah. 07:07.340 --> 07:09.550 So it says message you're out of tokens. 07:09.550 --> 07:12.300 Please refill status three or three. 07:12.440 --> 07:13.920 OK so that's the air. 07:14.270 --> 07:22.160 Now I need to refill so I'm going on right refill and then username my username so let's let me just 07:22.190 --> 07:24.080 copy this before I believe it. 07:24.080 --> 07:34.200 So I'm going I write user name is Faruq admin password is ABC 1 2 3 right ABC 1 2 3. 07:34.630 --> 07:41.710 And we're going to do the next one in-text do and we're gonna give it the refill amount. 07:41.710 --> 07:49.350 So I'm going to write refill and then for example for someone to give myself were tokens OK. 07:49.690 --> 07:50.790 So let's meet let's. 07:50.810 --> 07:57.310 And that last refill sells refilled successfully status 200. 07:57.310 --> 08:06.340 Now if I try to access the API again so I'm going to write the same to slash deduct the same Jason File 08:06.340 --> 08:12.000 to detect and I said that then it tells me a similarity score calculator. 08:12.010 --> 08:14.020 So now I have three tokens left. 08:14.160 --> 08:17.990 Now I can actually change this and I can write for example. 08:18.670 --> 08:21.200 Same sentence. 08:21.610 --> 08:26.780 And then here I would write also same sentence. 08:26.950 --> 08:32.050 And then it should be very very close to what rights are because they're exactly the same sentences. 08:32.050 --> 08:35.880 So if I send them then you would notice here that the ratio is one. 08:35.920 --> 08:36.730 Exactly. 08:36.730 --> 08:39.860 So these sentences are exactly identical. 08:40.880 --> 08:49.990 So yeah this is basically the entire API has three three ends or hit points register detect refill. 08:49.990 --> 08:54.830 We've tested it and it works fine and everything's working cool. 08:54.890 --> 08:58.670 So yeah we're going to stop here and I'll see you in the next video. 08:58.670 --> 09:00.840 So until the next video the.
