WEBVTT 00:03.790 --> 00:05.220 Hey, did everyone are they sure? 00:05.230 --> 00:06.940 And welcome to another video. 00:06.970 --> 00:11.410 In this video, we're going to talk about something that I kind of rushed through it, and some of you 00:11.410 --> 00:15.760 probably already know it, but I expect that you know nothing and that's where we are going to start. 00:15.910 --> 00:18.430 In case you didn't noticed, I wrote a get here. 00:18.430 --> 00:20.860 So what is this get and what it's going to do? 00:20.890 --> 00:23.350 Let's go ahead and talk more about this one. 00:23.650 --> 00:27.790 Now, whenever you make a Web request, there are types of Web requests that you make. 00:27.820 --> 00:32.890 Usually we really don't see or talk much about it because it's kind of obvious for us. 00:32.890 --> 00:35.890 But as a developer, that becomes a little bit more to us. 00:36.100 --> 00:41.410 Whenever you make a request to ask something from the Google, Google looks into the database and give 00:41.410 --> 00:42.100 it to you. 00:42.130 --> 00:48.190 That kind of request is known for the browser to make in most of the cases, but whenever you actually 00:48.190 --> 00:52.600 write in your email and password and you send it to Google and that validates it, that's a different 00:52.600 --> 00:58.240 kind of request because you are sending some data for the database itself and you're trying to just 00:58.240 --> 01:04.090 kind of put that data permanently, not in the case of log in, but definitely at the case of registration. 01:04.090 --> 01:07.510 So these kinds of things are made up of different web requests. 01:07.510 --> 01:12.820 Now, there are not too many of them for you to remember, but we call them as web request and they 01:12.820 --> 01:18.610 play a very important role at the time of building the web application, whether it's just rest API 01:18.610 --> 01:23.080 or something else, they are really important and good news is there are majorly four of them that we 01:23.080 --> 01:27.370 are going to talk, everybody talks, but there are a little bit more and I'll explain more of them. 01:27.460 --> 01:33.190 Simply putting get post, put and delete and no, there is no color code associated with them. 01:33.190 --> 01:37.060 Usually delete is marked as red, but there is no color code associated with them. 01:37.060 --> 01:39.520 I just put it because I felt these are good ones. 01:39.520 --> 01:45.370 Let's talk about them one by one and they are really simple get is for requesting the information. 01:45.430 --> 01:50.080 Let's just say you are onto a shopping website, you are searching for a term and it gives you a result 01:50.110 --> 01:50.340 back. 01:50.350 --> 01:57.490 These are all get operations and when you slide at just your pricing or maybe your filter by request 01:57.490 --> 02:01.840 or filter by rating, these all are get requests because you are not putting any information onto the 02:01.840 --> 02:03.700 database, you are just asking for it. 02:03.700 --> 02:09.610 And for all these kinds of asking information, we just go for request information and get type of request. 02:10.330 --> 02:14.150 In the case of post, it is usually add to database. 02:14.170 --> 02:19.330 Now what happens in this case, whenever there is information that you are sending something that probably 02:19.330 --> 02:25.980 is going to just add it onto the database itself, then definitely 100% it's supposed to request. 02:25.990 --> 02:30.880 Now, if a sensitive information is also traveling something like your password or something, it is 02:30.880 --> 02:35.890 recommended that web developers use a post request because in the post the data doesn't travel like 02:35.890 --> 02:39.120 in the URL or some place, which is really not that much safe. 02:39.130 --> 02:44.200 So in the case, whenever there is a database involved and you want to put some information or to store 02:44.230 --> 02:49.180 that permanently, then for such persistence information post request is being used. 02:49.270 --> 02:54.280 Another one is put whenever there is a database information which is already there, but you want to 02:54.280 --> 02:55.270 update it. 02:55.390 --> 02:57.700 That's where the put request comes in. 02:57.700 --> 03:01.540 For example, you want to change your username, you want to change your name, you want to change your 03:01.540 --> 03:02.320 photos. 03:02.380 --> 03:07.300 There is already something in the database and that's where the put request comes in. 03:07.390 --> 03:13.660 And finally, last but not the least, the delete request, which obviously is type of request delete 03:13.660 --> 03:15.550 and you delete something from the database. 03:15.550 --> 03:20.140 Now as a user, nobody cares about what kind of request they are sending as a web developer. 03:20.140 --> 03:22.450 Yes, we do care a lot about it now. 03:22.450 --> 03:23.170 Definitely not. 03:23.170 --> 03:28.750 These are the only ones, but these are the majorly being used in every single tech giant major of majority 03:28.750 --> 03:29.290 of them. 03:29.290 --> 03:35.320 But there is a link here to read more, and this is the official MD documentation that you can click 03:35.320 --> 03:38.170 from this web link and I'll give you all the presentation and everything. 03:38.170 --> 03:38.950 Don't do worry. 03:38.950 --> 03:41.840 So what you can see is majority. 03:41.860 --> 03:43.180 These kinds of requests are there. 03:43.180 --> 03:44.350 So there is a get request. 03:44.350 --> 03:47.170 Yes, of course there is a head request, but we don't use it that much. 03:47.170 --> 03:48.910 Yes, in the course we will be using it. 03:48.910 --> 03:50.500 But you don't have to worry too much on that. 03:50.500 --> 03:51.850 You automatically get that. 03:51.850 --> 03:52.870 You don't have to worry. 03:52.870 --> 03:57.280 Then there is a post put and delete that we talked about, but there is a connect, there is option 03:57.280 --> 03:58.960 trace and patch and all of that. 03:58.990 --> 04:00.270 You don't have to worry. 04:00.310 --> 04:05.470 Majority of the time you won't be seeing much of the people using it until unless you are building extremely 04:05.470 --> 04:06.640 complex application. 04:06.640 --> 04:11.110 And by the time you'll be having information about all four of them, it would be easier for you to 04:11.110 --> 04:12.460 understand the rest of them. 04:12.550 --> 04:12.870 Okay. 04:12.910 --> 04:17.920 So now that you are all done and you know the reason why I wrote a get here, because all of this is 04:17.920 --> 04:19.030 asking information. 04:19.030 --> 04:21.550 None of them is adding information on the database. 04:21.550 --> 04:25.840 We don't have a database yet, but this is all that you should know about the request. 04:25.840 --> 04:27.850 Read a little bit more on the documentation. 04:27.850 --> 04:29.200 Even if you don't understand it. 04:29.200 --> 04:32.170 Just glimpsing through over it is always a good idea. 04:32.170 --> 04:34.480 Let's go ahead and catch up in the next video.
