Alright, here we are in our GitHub Repo.
0:03
In the Uplink directory, we're going to
0:05
quickly create a virtual environment.
0:06
We're going to want to install some third party packages,
0:09
namely uplink and all of its dependencies.
0:11
So, you want to have this here, so you don't mess
0:14
with the global one.
0:17
Now that that's done, we can just drop this into PyCharm,
0:20
open it however you like.
0:23
Alright, it's open, there's no files,
0:25
we're starting from an entirely blank project.
0:28
So let's do two things,
0:29
let's go over here and add a program
0:33
and let's add a requirements.txt.
0:36
So, in order to work with Uplink,
0:39
it probably won't surprise you to know,
0:40
you have to install Uplink.
0:42
So we'll come over here and say uplink.
0:43
Now, we're going to install this,
0:45
however, let's quickly look at the Uplink documentation.
0:49
So, you can see it's really targeting
0:50
all the versions of Python,
0:52
great code coverage, really nice,
0:54
however, there is this sort of note here:
0:57
warning, until this becomes an official version one,
1:01
maybe don't depend on the exact stability of the API.
1:05
Chances are, what we're doing
1:06
is really pretty basic and won't change,
1:09
but I'll show you how we can hedge for that in a second.
1:11
So let's go over here.
1:15
Install our requirements,
1:17
and notice, we got Uplink 0.4.0
1:20
and we can actually...
1:22
This will go away in a second.
1:23
We can come over here and say this is actually
1:25
== to this.
1:26
And when we do this, it should still just say:
1:29
"No, no we're all good, everything's installed."
1:31
That way, when you get this project,
1:34
you can put this and it won't change.
1:36
In case that API really is unstable,
1:38
this will let you work with exactly
1:40
what we're using for this video.
1:42
Now this little green here is just PyCharm saying
1:44
this is misspelled.
1:46
We can just save it, tell it no, leave us alone.
1:48
Okay, so we are ready, actually to write some code.
1:52
And let's just put a little bit of structure in place.
1:56
What we're going to do it we're going to work with a blog service.
1:58
So, imagine this is a program that
2:00
lets us edit our own blog, but not from the web.
2:04
We're going to log into our application here
2:07
and we can say view our existing post,
2:09
edit our post, we can create new posts,
2:13
really kind of a toy example but,
2:14
it has much of the RESTful components
2:17
that any API would have.
2:18
So, it accepts POST, PUT, DELETE,
2:21
the various verbs and JSON bodies,
2:24
and other types of interesting things,
2:26
authentication and headers,
2:27
and it'll let you play around
2:28
with many of the capabilities without
2:30
getting into a really super complicated service.
2:33
So let's just write the skeleton here
2:35
and then we'll go check out the service.
2:36
Alright, so I'm going to just copy something in
2:38
and it's just going to like this.
2:40
So, what we're going to do, is we're going to define
2:42
basically a couple of operations here.
2:44
We'll use this one first.
2:45
So we're going to have a main method
2:47
and it's just going to go around and around
2:48
as long as you don't enter a blank line,
2:51
it's going to ask you, would you like to write a post?
2:54
Or, read the existing ones?
2:55
The service starts out with some already there.
2:57
And then it just says each time through,
2:59
do they say write, do they say read, if not exit.
3:04
We're going to fill this out with the implementation
3:06
of talking to the API.
