名称“privtopub”未定义

Question

My code looks like:

from django.shortcuts import render, redirect
from django.contrib.auth.models import User, auth
from django.contrib import messages
from .models import Details
from bitcoin import *
import random
import bs4
import requests

def login(request):

    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']

        user = auth.authenticate(username=username, password=password)

        if user is not None:
            auth.login(request, user)
            return redirect('/')
        else:
            messages.info(request, 'Invalid Credentials')
            return redirect('login')

    else:
        return render(request, 'login.htm')

def register(request):

    detail = Details()
    bits = random.getrandbits(256)
    bits_hex = hex(bits)
    private_key = bits_hex[2:]
    print(private_key)
    # private_key = random_key()
    public_key = privtopub(private_key)
    address = pubtoaddr(public_key)
    detail.private_key = private_key
    detail.public_key = public_key
    detail.address = address

But I get the error: name 'privtopub' is not defined

Answer 1

I would start by importing bitcoin as:

import bitcoin

rather than

from bitcoin import *

The latter is not ideal programming practice and is said to "clutter the name space."

Then change your:

public_key = privtopub(private_key)

to:

public_key = bitcoin.privtopub(private_key)

and see if your problem goes away.

Also, it looks like privtopub() may be an alias for privkey_to_pubkey() . So maybe your version of bitcoin is older and doesn't have the alias. If so, you can also try just calling the method by the longer name.
