WEBVTT 00:00.140 --> 00:00.680 Hi everyone. 00:00.680 --> 00:01.220 Welcome back. 00:01.220 --> 00:07.280 In this lecture we will learn about how to build the Rest client for the API that returns all the movies. 00:07.280 --> 00:07.640 Right? 00:07.640 --> 00:11.270 Which means an API that's going to return an array actually. 00:11.270 --> 00:14.930 So in this case let's copy this one over here and then go to the browser. 00:14.960 --> 00:17.540 So in the browser if you paste this URL. 00:17.540 --> 00:19.820 So this is going to give you an array of response. 00:19.820 --> 00:21.980 In this case as you can see it starts with an array. 00:21.980 --> 00:24.200 And then it has this ten movies. 00:24.200 --> 00:26.990 And then it ends with an array element okay. 00:27.020 --> 00:28.220 So now what we are going to do. 00:28.250 --> 00:32.120 We are going to write the code that's going to return a collection of movies. 00:32.120 --> 00:36.260 So so far our client that we had built returned a single movie. 00:36.290 --> 00:40.280 Now we are going to write a client that's going to return a list of movies. 00:40.310 --> 00:43.730 So in this case let's go ahead and create a new function. 00:43.730 --> 00:46.130 But the code logic is going to be pretty much the same. 00:46.160 --> 00:51.710 So in this case let's copy this and then put it over here I'm going to name this one as get all movies 00:51.740 --> 00:51.920 okay. 00:51.950 --> 00:56.750 It's not going to be Get movie by ID it's going to be get all movies. 00:56.750 --> 01:03.320 And then in the place of movie by ID URL, we will pass the all movies Movie's URL. 01:03.440 --> 01:06.560 In this case, let's pass the all movie's URL over here. 01:06.560 --> 01:12.230 So when we get the response from this client, what we are going to get is an array of movies, right? 01:12.230 --> 01:14.810 So that's going to be part of the HTTP response tool. 01:14.810 --> 01:19.940 And then in the place of body, that whole HTTP array element is going to be present. 01:19.940 --> 01:25.730 So in the case of parsing this from a single movie to an array, what we have to do is there is an way 01:25.730 --> 01:30.110 in object mapper you can actually apply the array deserialization. 01:30.110 --> 01:33.290 So in this case what we can do is there is a class name new type reference. 01:33.290 --> 01:35.420 And then all you got to do is provide this one. 01:35.420 --> 01:38.480 So this should automatically apply that logic for you. 01:38.480 --> 01:40.310 I don't think we even need this one actually. 01:40.310 --> 01:41.420 Let's go ahead and remove it. 01:41.420 --> 01:43.010 So all you got to do is do this. 01:43.010 --> 01:48.860 This should take care of automatically converting that string array into a array of movies. 01:48.890 --> 01:51.260 So in this case let's go ahead and remove this one. 01:51.260 --> 01:53.270 And then this is going to be a list of movie. 01:53.300 --> 01:56.330 So in this case it's going to be list of movie. 01:56.870 --> 01:59.990 So let's go ahead and import the necessary classes. 02:00.110 --> 02:01.100 There you go. 02:01.130 --> 02:01.670 There we go. 02:01.670 --> 02:06.650 So this specific logic is going to take care of automatically Dramatically converting a string array 02:06.650 --> 02:11.270 to an array of movies, or in this case, it's going to be a collection of movies. 02:11.390 --> 02:15.740 So in this case, what we can do, we can write a test very similar to what we did over here. 02:16.220 --> 02:17.120 Put it over here. 02:17.120 --> 02:24.320 But instead of get movie by ID, we're going to call get all movies by ID, get all movies by ID and 02:24.320 --> 02:26.390 get all movies by ID over here. 02:26.390 --> 02:29.060 So in this case, we can change our assertions a little bit. 02:29.060 --> 02:33.170 So what we can do is we know this list is going to hold ten elements. 02:33.170 --> 02:35.930 So what we can do so we can do assert. 02:37.370 --> 02:40.730 So we can name this one as movies list. 02:40.730 --> 02:45.920 And we can have movies list dot size equal to equal to ten. 02:45.950 --> 02:47.420 Okay we can do that. 02:47.420 --> 02:50.060 And then we can actually complete our assertions. 02:50.060 --> 02:55.250 This is good enough for to make sure that our code is going to work as expected. 02:55.250 --> 02:59.180 So now what we're going to do we're going to execute the specific test case. 02:59.180 --> 03:04.640 So the specific test case is going to make sure it's going to call this function and then return the 03:04.640 --> 03:05.840 value as an array. 03:06.230 --> 03:06.560 There we go. 03:06.590 --> 03:08.430 We got the response as is an array. 03:08.430 --> 03:11.070 And our assertion was also successful. 03:11.070 --> 03:15.390 So in this case, another thing that you want to see if you want to see what is actually being returned. 03:15.390 --> 03:18.150 So you can actually add a short over here. 03:18.150 --> 03:21.510 And then in this episode, what we can do is we can actually print the body. 03:21.510 --> 03:30.180 So in this case we can say response body is and then we can provide plus HTTP response dot body. 03:30.180 --> 03:35.520 So this can print the whole body in the console so that you can see what's returned from this specific 03:35.520 --> 03:36.330 endpoint. 03:37.500 --> 03:38.940 Let's execute this test case. 03:38.970 --> 03:39.600 There you go. 03:39.600 --> 03:43.350 So this specific test case is printed this whole JSON array. 03:43.380 --> 03:47.190 So basically JSON array being parsed as a string. 03:47.190 --> 03:48.420 And that's what this one is. 03:48.420 --> 03:53.370 And then this string gets converted into a list of movies using this specific code. 03:53.400 --> 03:57.120 I hope you all have a pretty good idea about how to build an HTTP client. 03:57.120 --> 04:02.100 That's going to be dealing with an array of elements, and using the object mapper, we were able to 04:02.100 --> 04:06.150 convert that array of elements into a collection of elements. 04:06.150 --> 04:08.160 In this case, that element is a movie. 04:08.160 --> 04:09.600 This marks the end of this lecture. 04:09.600 --> 04:10.770 Thank you for watching.
