- [] Describe the client-server model and request-response cycle
- [] Identify examples of clients and servers, both on their local computers and remotely connected
- [] Identify examples of requests and responses
- [] Understand the difference between a request that returns HTML and an API request that returns JSON
- [] Understand the basic pieces of making HTML and JSON requests
- For simple requests, you only need 2 things: HTTP verb and URL
- HTTP verb: this will almost always be
GET
, kind of like how a data scientist's SQL query will almost always beSELECT
. But there are other verbs, includingPOST
andPATCH
, which are likeINSERT INTO
andUPDATE
- URL: this is the string representing the location of the resource. It can also be called a "path", or an "endpoint"
- [] Use a browser to make HTML and JSON requests
- This just means typing the URL into the browser. It will always be a
GET
request. - The browser will show HTML or JSON depending on the URL. So,
reddit.com
shows you HTML, whereasreddit.com/.json
shows you JSON.
- This just means typing the URL into the browser. It will always be a
- [] Use Postman to make HTML and JSON requests
- Postman has input fields where you can type the URL and select the HTTP verb from a drop-down
- Remember that this is a good tool for exploration/figuring out how to use an API (better than Chrome), but it's not the final product
- [] Practice reading someone else's Python code that uses the
requests
library - [] Use Python
requests
library to make JSON requests - [] Practice reading the documentation for an API
