下载 zip 并解析 django 中的 csv 文件，将数据复制到本地 DB(sqllite)

Question

I have a url, which downloads a zip file, containing a csv file. I want to parse the data and import it to local Database(sqlite) in Django.

In brief, input = url, pre-processing download.zip-> convert to.csv, output=csv rows in DB which has columns of csv as fields.

Answer 1

Well, I think if you google a bit you can do it yourself. I will give you the keyword:

• For download a file you can you use request:

import requests

url = 'https://www.facebook.com/favicon.ico' r = requests.get(url, allow_redirects=True)

open('facebook.ico', 'wb').write(r.content)

• To parse a csv file use xlsxwriter

• To save the data to database, I suggest you save the data to django model then call model.save()

To use it as a service you should use rest_framework and write a custom viewset like this. I had quite a hard time get familiar with it, so good luck, but when you get long, drf is quite handy tool for everything, just not fast.

You should django settings to save the path to temp file. In linux you can use /tmp
