import requests issue

[cataYT]

from python import Python
import requests

fn main():

# URL you want to send a GET request to
let url = 'https://jsonplaceholder.typicode.com/todos/1'

# Send the GET request
let response = requests.delete(url)

# Check if the request was successful (status code 200)
if response.status_code == 200:
    print('Request was successful')
    print('Response content:')
    print(response.text)
else:
    print(f'Request failed with status code {response.status_code}')

let save = str(input("Do you want to save the response?: "))

if save.lower() == "yes" or save.lower() == "y":

    let saveFile = open("response.json", "w")

    saveFile.write(f"{response.text}")

    saveFile.close()

In the above program, it says unable to locate requests so my question is there a mojo version for this?

There's not a Mojo version of requests yet, but I believe you can try another way.

from python import Python

fn main():
    try:
        let requests = Python.import_module("requests")
        # URL you want to send a GET request to
        let url = 'https://jsonplaceholder.typicode.com/todos/1'

        # Send the GET request
        let response = requests.delete(url)

        # Check if the request was successful (status code 200)
        if response.status_code == 200:
            print('Request was successful')
            print('Response content:')
            print(response.text)
        else:
            print('Request failed with status code', response.status_code)

    except:
        print("didn't work")

I don't yet see a way to write to files built in, you may have to code that by hand. Unfortunately that's above my level. But I'm trying to learn everything I can about the language while it's new and minimal so over time I can just add to my knowledge.

this one worked! thanks

I know this has been answered already, and that I provided the correct answer... but I happened to have this problem opened in my editor when I sat down tonight.
So I've been messing around with it. I've come up with this solution to provide both requests usage and write file functionality.

from python import Python


fn write_file(content: String) raises:
    '''
    Uses pythons builtins to open and write a file.
    '''
    let builtins = Python.import_module("builtins")
    let save = builtins.str(builtins.input("Save a file?"))
    if save.lower() == "yes" or save.lower() == "y":
        let saveFile = builtins.open("test.json", "a")
        _ = saveFile.write(content)
        _ = saveFile.close()


fn main() raises:
    '''
    Makes a request with pythons request module and returns the response.
    '''

    let requests = Python.import_module("requests")
    # URL you want to send a GET request to
    let url = 'https://jsonplaceholder.typicode.com/todos/2'

    # Send the GET request
    let response = requests.get(url)

    # Check if the request was successful (status code 200)
    if response.status_code == 200:
        print('Request was successful')
        print('Response content:')
        print(response.text)
        let resp = response.text
        write_file(resp.to_string())
    else:
        print('Request failed with status code', response.status_code)

In mojo, you can't just import python modules like in python. So this won't work

import requests

And MikeCase is also right that there doesn't seem to be a way in mojo yet to do any kind of mojo native File or Networking IO. You can get the open function through python's __builtins__ (which normally is automatically imported in python, but you can explicitly import it too with import builtins). Also you won't be able to use a Context Manager in mojo yet.

I haven't tested this myself, but try this

fn main():
    let bi = Python.import_module("builtins")
    let requests = Python.import_module("requests")

    let url = 'https://jsonplaceholder.typicode.com/todos/1'
  
    # Send the GET request
    let response = requests.delete(url)
  
    # Check if the request was successful (status code 200)
    if response.status_code == 200:
        print('Request was successful')
        print('Response content:')
        print(response.text)
    else:
        print(f'Request failed with status code {response.status_code}')
  
    let save = bi.str(bi.input("Do you want to save the response?: "))
    if save.lower() == "yes" or save.lower() == "y":
        let saveFile = bi.open("response.json", "w")
        saveFile.write(f"{response.text}")
        saveFile.close()

You may also get a warning about a shared python library not being found if you compile it as an executable

Python interoperability might fail when running a compiled Mojo program, with the message Unable to locate a suitable libpython, please set MOJO_PYTHON_LIBRARY. This is because we currently do not embed the Python version into the Mojo binary. For details and the workaround, see issue #551.

it gives me this error:

./test.mojo:2:14: error: use of unknown declaration 'Python', 'fn' declarations require explicit variable declarations
let bi = Python.import_module("builtins")
^~~~~~
./test.mojo:3:20: error: use of unknown declaration 'Python', 'fn' declarations require explicit variable declarations
let requests = Python.import_module("requests")
^~~~~~
mojo: error: failed to parse the provided Mojo

Sorry, I didn't include the full mojo file. At the top you need to import Python

from python import Python

fn main():
    let bi = Python.import_module("builtins")
    let requests = Python.import_module("requests")

    let url = 'https://jsonplaceholder.typicode.com/todos/1'
  
    # Send the GET request
    let response = requests.delete(url)
  
    # Check if the request was successful (status code 200)
    if response.status_code == 200:
        print('Request was successful')
        print('Response content:')
        print(response.text)
    else:
        print(f'Request failed with status code {response.status_code}')
  
    let save = bi.str(bi.input("Do you want to save the response?: "))
    if save.lower() == "yes" or save.lower() == "y":
        let saveFile = bi.open("response.json", "w")
        saveFile.write(f"{response.text}")
        saveFile.close()
