Arrays have size - a fixed size, and cannot be resized (length is part of its type). How to declare: [size]type{} To create an empty array: var a [2]string an array of 2 values of type string. Can not mix types func main() { var a [2]int // if need just empty array b := [2]string{"one"} // with some elements in the array b[1] = "two" a[0] = 0 a[1] = 1 fmt....

I just discovered that we can add syntax highlighting to the markdown file. Very nice! ```<language> code```

FastAPI has two documentations: by swagger-ui (yourfastapiurl:port/docs) by redoc (yourfastapiurl:port/redoc) from fastapi import FastAPI app = FastAPI() @app.get("/") async def root(): return {"result": "It's working"} @app.get("/ise/{mac_address}") async def ise_search_mac_address(mac_address): return {"Search MAC": mac_address} @app.get("/{mode}/ise") async def ise_mode(mode): if mode == 'dev': return {'result': "Working with Dev ISE"} return {'result': "Working with Prod ISE"} http://127.0.0.1:8089/docs/ Also you can try it right there: http://127.0.0.1:8089/redoc/ And for sure, great FastAPI Documentation itself: here

Learning Go is exciting. Decided to see how to set up a Web Application or API using Go language along with FastAPI implementation. package main import ( "log" "net/http" ) // Define a home handler function func home(w http.ResponseWriter, r *http.Request) { w.Write([]byte("Hello from Goooooo")) } func main() { // http.NewServeMux() function to initialize a new servemux mux := http.NewServeMux() // match "/" URL pattern with home handler function mux.HandleFunc("/", home) // http....

A quick note about how to pass parameters @app.get("/ise/{mac_address}") async def ise_search_mac_address(mac_address): return {"Search MAC": mac_address} Another example: @app.get("/{mode}/ise") async def ise_mode(mode): if mode == 'dev': return {'result': "Working with Dev ISE"} return {'result': "Working with Prod ISE"}

Short and easy FastAPI startup for a quick playground and testing. pip install fastapi pip install uvicorn – main.py – from fastapi import FastAPI app = FastAPI() @app.get("/") def read_root(): return {"Hello": "World"} @app.get("/hello") def read_root(): return {"Hello": "Hello"} To start using uvicorn: uvicorn app.main:app --host 127.0.0.1 --port 8089

Nice, useful, and easy-to-use feature in FastAPI. It allows responding to the client and doing whatever needs to be done after the request, the client doesn’t have to wait for the operation to complete. For example, get an API request, respond to the client right away, do the job and send a notification once it’s done as a separate event.

More of Go I have already migrated some scripts from python to go, mostly with API. Decided to check how to SSH into network devices and run some commands. Of course, I used the well-known cisco always-on sandbox. note: using some code as a core and as an example (link in the comments Everything is pretty straightforward here: var ( User string = "developer" Password string = "C1sco12345" hosts = []string{"sandbox-iosxe-latest-1....

Go (Golang) is fast. This phrase is everywhere. It’s always interesting how long it takes a function to finish its operation. Here is an example of a helper function, that could be used to check and log the timing: func TimeTrack(start time.Time, name string) { elapsed := time.Since(start) log.Printf("%s took %s", name, elapsed) } It takes a start time and the name (could be a function name) as parameters. Use it with the “defer” statement inside the functions:...

Using Environment in Postman is one of the best things that we can use during the testing and while playing around with API. Postman makes this development phase much easier. API is getting more to the token-centric authentication and Environment Variable becomes handy. I will use Cisco Sandbox for my examples, that is one of the great ways to get some practice with Cisco products API. Setting up Postman Environment Variables:...
